CBCS Practice Questions

1. In the medical revenue cycle, which phase includes patient registration, insurance verification, and collection of demographic information before services are rendered?
   • The front-end phase
   • The back-end phase
   • The adjudication phase
   • The collections phase

   Correct answer: The front-end phase

   The front-end phase is correct because the revenue cycle begins before care is delivered with scheduling, patient registration, demographic capture, and insurance verification. The back-end phase covers claim submission, payment posting, and follow-up after the encounter, so registration tasks do not belong there.

2. A billing specialist needs to describe the overall purpose of the revenue cycle to a new employee. Which statement best captures it?
   • It manages all clinical decisions made during a patient encounter
   • It tracks administrative and clinical functions that capture, manage, and collect patient service revenue
   • It is limited to printing and mailing patient statements
   • It only applies to government insurance programs

   Correct answer: It tracks administrative and clinical functions that capture, manage, and collect patient service revenue

   Tracking the administrative and clinical functions that capture, manage, and collect patient service revenue is the correct description. The revenue cycle spans from pre-registration through final payment, not just statements or government payers, and it concerns financial workflows rather than clinical care decisions.

3. Which of the following best identifies the back-end functions of the revenue cycle?
   • Patient scheduling and pre-registration
   • Insurance eligibility checks at the front desk
   • Claim submission, payment posting, denial follow-up, and collections
   • Capturing patient demographics during intake

   Correct answer: Claim submission, payment posting, denial follow-up, and collections

   Claim submission, payment posting, denial follow-up, and collections are the back-end functions because they occur after the service is provided. Scheduling, pre-registration, eligibility verification, and demographic capture all happen on the front end before care.

4. What is the primary purpose of the HIPAA Privacy Rule?
   • To establish billing codes for outpatient procedures
   • To determine Medicare reimbursement rates
   • To require electronic submission of all claims
   • To set national standards for protecting individuals' protected health information

   Correct answer: To set national standards for protecting individuals' protected health information

   Setting national standards to protect individuals' protected health information is the correct purpose. The Privacy Rule governs the use and disclosure of PHI; it does not assign procedure codes, set reimbursement rates, or mandate electronic claim formats, which are handled by other rules and code sets.

5. Under the HIPAA Privacy Rule, a provider may disclose a patient's protected health information without the patient's written authorization for which purpose?
   • Treatment, payment, and health care operations
   • Selling the information to a marketing firm
   • Posting the information publicly to verify identity
   • Sharing it with an employer for hiring decisions

   Correct answer: Treatment, payment, and health care operations

   Treatment, payment, and health care operations is the correct answer because the Privacy Rule permits these core disclosures without separate written authorization. Selling PHI for marketing, posting it publicly, or releasing it to an employer for hiring all require authorization or are prohibited.

6. A patient asks the billing office to send copies of his medical records to a new physician. Under the HIPAA Privacy Rule, this disclosure falls under which permitted category?
   • Marketing
   • Treatment
   • Research
   • Public health reporting

   Correct answer: Treatment

   Treatment is correct because transferring records to another provider who is caring for the patient supports continuity of care. Marketing requires authorization, research has its own safeguards, and public health reporting addresses population surveillance rather than coordinating an individual patient's ongoing care.

7. Which of the following is considered protected health information (PHI) under HIPAA?
   • A general statistic about the number of flu cases nationwide
   • A blank claim form template
   • A patient's name combined with a diagnosis and date of service
   • An employee's payroll schedule

   Correct answer: A patient's name combined with a diagnosis and date of service

   A patient's name combined with a diagnosis and date of service is PHI because it links health information to an identifiable individual. Aggregate national statistics, blank form templates, and employee payroll data do not identify an individual's health condition, so they are not PHI.

8. Protected health information is best defined as individually identifiable health information that is which of the following?
   • Only information stored on paper
   • Limited to information about communicable diseases
   • Any information a hospital chooses to label confidential
   • Created or received by a covered entity and relating to a person's health, care, or payment

   Correct answer: Created or received by a covered entity and relating to a person's health, care, or payment

   Information created or received by a covered entity that relates to an individual's health condition, care, or payment is the correct definition. PHI applies to any medium, not just paper, and is not limited to communicable diseases or to whatever a facility arbitrarily labels confidential.

9. A billing specialist removes a patient's name, address, dates, and all 18 HIPAA identifiers from a record before using it for a training exercise. What has occurred?
   • The information has been de-identified and is no longer PHI
   • The information has been encrypted
   • The information has become a breach
   • The information is now subject to the False Claims Act

   Correct answer: The information has been de-identified and is no longer PHI

   De-identification is correct because removing all 18 HIPAA identifiers means the data can no longer be tied to an individual, so it is no longer PHI. Encryption only scrambles data while it remains PHI, and removing identifiers is a protective step rather than a breach or a claims-payment issue.

10. Which of the following is a covered entity required to comply with HIPAA?
    • A patient receiving care
    • A health care clearinghouse
    • A newspaper reporting on a hospital
    • A medical equipment manufacturer that does not bill insurers

    Correct answer: A health care clearinghouse

    A health care clearinghouse is a covered entity because HIPAA defines covered entities as health plans, health care clearinghouses, and providers who transmit health information electronically. Patients, the press, and a manufacturer that does not conduct covered transactions are not covered entities.

11. Which list correctly names the three types of covered entities under HIPAA?
    • Patients, providers, and employers
    • Hospitals, pharmacies, and laboratories only
    • Health plans, health care clearinghouses, and providers who transmit health information electronically
    • Federal agencies, state agencies, and local agencies

    Correct answer: Health plans, health care clearinghouses, and providers who transmit health information electronically

    Health plans, health care clearinghouses, and providers who transmit health information electronically are the three covered entities defined by HIPAA. Patients and employers are not covered entities, and the other options describe only subsets of providers or government bodies rather than the defined categories.

12. A medical billing company performs claims processing on behalf of a physician practice and handles PHI. What is this company's relationship to the practice under HIPAA?
    • It is a covered entity itself
    • It is exempt from HIPAA
    • It is a patient representative
    • It is a business associate

    Correct answer: It is a business associate

    A business associate is correct because a vendor that handles PHI to perform functions on behalf of a covered entity is a business associate and must sign a business associate agreement. The billing company is not itself a covered entity, is not exempt, and does not act as the patient's representative.

13. Which scenario is the best example of health care fraud rather than abuse?
    • Knowingly billing for services that were never provided
    • Inconsistently following a payer's documentation standards
    • Occasionally ordering tests that are slightly above necessity
    • Using an outdated fee schedule by mistake

    Correct answer: Knowingly billing for services that were never provided

    Knowingly billing for services that were never provided is fraud because fraud requires intentional deception for unlawful gain. Inconsistent documentation, occasional unnecessary tests, and mistaken use of an old fee schedule reflect abuse or error, which lack the deliberate intent that defines fraud.

14. What is the key distinction between fraud and abuse in health care billing?
    • Fraud applies only to Medicaid and abuse applies only to Medicare
    • Fraud involves intentional deception while abuse involves practices inconsistent with accepted standards without proven intent
    • Abuse is always a felony while fraud is a misdemeanor
    • There is no legal difference between the two terms

    Correct answer: Fraud involves intentional deception while abuse involves practices inconsistent with accepted standards without proven intent

    The distinction is that fraud involves intentional deception or misrepresentation while abuse involves practices inconsistent with accepted business or medical standards without established intent. The other choices misstate program scope, severity, and incorrectly claim the terms are interchangeable.

15. A provider routinely waives all patient copayments without a financial hardship assessment. This practice is most accurately classified as which of the following?
    • A clean claim
    • A required courtesy under HIPAA
    • Abuse that can lead to fraud and compliance violations
    • An approved write-off under every payer policy

    Correct answer: Abuse that can lead to fraud and compliance violations

    Routinely waiving copayments without documenting hardship is abuse that can escalate to fraud and compliance violations because it can misrepresent the true charge and induce overutilization. It is not a clean claim, is not required by HIPAA, and is not universally approved by payer policies.

16. The federal False Claims Act primarily addresses which of the following?
    • Standards for electronic health record interoperability
    • Setting CPT code values
    • Protecting the confidentiality of mental health records
    • Knowingly submitting false or fraudulent claims for payment to the government

    Correct answer: Knowingly submitting false or fraudulent claims for payment to the government

    Knowingly submitting false or fraudulent claims for government payment is the focus of the False Claims Act. The statute does not govern EHR interoperability standards, set CPT values, or address mental health record confidentiality, which fall under other laws and code sets.

17. Under the False Claims Act, what is the term for a private individual who files a lawsuit on behalf of the government alleging false claims?
    • A whistleblower (qui tam relator)
    • A covered entity
    • A clearinghouse
    • A business associate

    Correct answer: A whistleblower (qui tam relator)

    A whistleblower, known as a qui tam relator, is correct because the False Claims Act allows private citizens to file qui tam lawsuits and potentially share in recoveries. A covered entity, clearinghouse, and business associate are HIPAA roles unrelated to bringing a qui tam action.

18. A billing specialist discovers that the practice has been submitting claims using a higher-level service code than the documentation supports. Which federal law is most directly implicated?
    • The Anti-Kickback Statute only
    • The False Claims Act
    • The Privacy Rule
    • The Security Rule

    Correct answer: The False Claims Act

    The False Claims Act is implicated because knowingly submitting claims that overstate the level of service constitutes a false claim for government payment. The Privacy and Security Rules govern PHI protection, not billing accuracy, and the scenario describes claim falsity rather than illegal remuneration.

19. What does the National Provider Identifier (NPI) uniquely identify?
    • An individual patient
    • A specific diagnosis code
    • A health care provider for use in standard transactions
    • A type of insurance plan

    Correct answer: A health care provider for use in standard transactions

    The NPI uniquely identifies a health care provider for use in HIPAA standard transactions. It is not a patient identifier, a diagnosis code, or a plan identifier; it is a 10-digit number assigned to providers and required on claims.

20. How many digits make up a standard National Provider Identifier (NPI)?
    • 9 digits
    • 11 digits
    • 15 digits
    • 10 digits

    Correct answer: 10 digits

    A standard NPI is 10 digits. A 9-digit number describes a Social Security number or EIN, and the NPI is neither 11 nor 15 digits; the single 10-digit NPI replaced legacy provider numbers for HIPAA transactions.

21. A claim is rejected because the rendering provider's identifier is missing from the required field. Which identifier must be entered to correct this issue?
    • The National Provider Identifier (NPI)
    • The patient's Social Security number
    • The CPT modifier
    • The place of service code

    Correct answer: The National Provider Identifier (NPI)

    The National Provider Identifier must be entered because the NPI is the standard provider identifier required on claims. A patient Social Security number identifies the patient, while a CPT modifier and place of service code describe the service rather than the provider.

22. What does the term medical necessity refer to in the context of billing and compliance?
    • Any service a patient requests
    • Services that are documented as reasonable and necessary for the diagnosis or treatment of a condition
    • The most expensive treatment option available
    • Services provided only in an emergency room

    Correct answer: Services that are documented as reasonable and necessary for the diagnosis or treatment of a condition

    Medical necessity refers to services that are reasonable and necessary for the diagnosis or treatment of a patient's condition and meet accepted standards of care. It is not defined by patient requests, cost, or care setting; payers tie coverage to documented necessity.

23. A payer denies a claim stating the diagnosis does not support the procedure performed. This denial is based on which compliance concept?
    • A HIPAA breach
    • A timely filing violation
    • Lack of medical necessity
    • An NPI mismatch

    Correct answer: Lack of medical necessity

    Lack of medical necessity is correct because a denial citing that the diagnosis does not support the procedure means the service was not shown to be reasonable and necessary. A HIPAA breach concerns PHI disclosure, and timely filing and NPI issues address deadlines and provider identification, not diagnosis-to-procedure linkage.

24. To support medical necessity for a billed service, the documentation in the patient record must do which of the following?
    • Be written only by the billing specialist
    • Be limited to the diagnosis code with no clinical notes
    • Always recommend the highest-cost treatment
    • Match the level and type of service reported on the claim

    Correct answer: Match the level and type of service reported on the claim

    The documentation must match the level and type of service reported on the claim so the record substantiates what was billed. Documentation is created by clinicians, must include supporting clinical detail beyond a code, and necessity is judged by appropriateness rather than cost.

25. Which agency primarily administers and enforces the federal regulations governing Medicare and Medicaid program integrity, including fraud and abuse oversight?
    • The Centers for Medicare & Medicaid Services (CMS) with the Office of Inspector General (OIG)
    • The Food and Drug Administration
    • The Federal Trade Commission
    • The Occupational Safety and Health Administration

    Correct answer: The Centers for Medicare & Medicaid Services (CMS) with the Office of Inspector General (OIG)

    CMS together with the Office of Inspector General is correct because CMS administers Medicare and Medicaid while the OIG investigates fraud, waste, and abuse in these programs. The FDA, FTC, and OSHA regulate drugs and devices, trade practices, and workplace safety respectively, not program-integrity oversight.

26. A breach of unsecured protected health information has occurred at a covered entity. Under HIPAA breach notification requirements, the entity must generally notify which parties?
    • Only the entity's internal staff
    • The affected individuals and the Secretary of HHS
    • Only the patient's primary physician
    • No one, as breaches are handled internally

    Correct answer: The affected individuals and the Secretary of HHS

    Notifying the affected individuals and the Secretary of HHS is required because the Breach Notification Rule mandates notice to those whose PHI was compromised and to HHS, with media notice for large breaches. Limiting notice to internal staff, one physician, or no one fails the rule's requirements.

27. Why is verifying medical necessity before a service important to the revenue cycle?
    • It guarantees the highest possible reimbursement
    • It eliminates the need for an NPI on the claim
    • It reduces the risk of denials and supports compliant claims
    • It removes the requirement to obtain patient demographics

    Correct answer: It reduces the risk of denials and supports compliant claims

    Verifying medical necessity reduces the risk of denials and supports compliant claims because services lacking documented necessity are frequently denied. It does not guarantee higher payment, does not waive the NPI requirement, and does not remove the need to collect patient demographics.

28. A billing specialist accesses the medical record of a celebrity patient out of personal curiosity, with no work-related reason. This action is best described as which of the following?
    • A permitted disclosure for operations
    • An acceptable use because the specialist is an employee
    • A de-identification process
    • A HIPAA Privacy Rule violation involving unauthorized access to PHI

    Correct answer: A HIPAA Privacy Rule violation involving unauthorized access to PHI

    Accessing the record without a work-related reason is a HIPAA Privacy Rule violation because PHI access must be limited to the minimum necessary for a legitimate job function. Curiosity is not a permitted operations purpose, employment does not authorize unrestricted access, and viewing identifiable data is not de-identification.

29. Which principle of the HIPAA Privacy Rule directs that only the least amount of PHI needed to accomplish a task should be used or disclosed?
    • The minimum necessary standard
    • The assignment of benefits
    • The clean claim standard
    • The coordination of benefits rule

    Correct answer: The minimum necessary standard

    The minimum necessary standard is correct because it requires limiting PHI use and disclosure to the smallest amount needed for the intended purpose. Assignment of benefits, clean claim, and coordination of benefits are billing concepts unrelated to limiting PHI exposure.

30. A provider gives a patient a free smartwatch in exchange for referring other Medicare patients to the practice. Beyond general fraud and abuse concerns, this arrangement most directly raises which compliance issue?
    • A timely filing problem
    • An illegal kickback for referrals of federal program patients
    • A de-identification failure
    • A coordination of benefits error

    Correct answer: An illegal kickback for referrals of federal program patients

    Offering something of value to induce referrals of federal program patients is an illegal kickback, a core fraud and abuse compliance issue. Timely filing concerns deadlines, de-identification concerns PHI, and coordination of benefits concerns determining the primary payer, none of which describe paying for referrals.

31. Which statement about the National Provider Identifier (NPI) is accurate?
    • A provider's NPI changes each year
    • The NPI is assigned to each patient encounter
    • The NPI stays with the provider regardless of job or location changes
    • The NPI is a temporary number used only for one claim

    Correct answer: The NPI stays with the provider regardless of job or location changes

    The NPI stays with the provider regardless of job or location changes because it is a permanent, unique identifier. It does not change annually, is not assigned per encounter, and is not a single-use temporary number; it persists across the provider's career.

32. When does the revenue cycle for a patient encounter typically begin?
    • When the claim is submitted to the payer
    • When the remittance advice is received
    • When the patient pays the final balance
    • When the patient schedules an appointment and is pre-registered

    Correct answer: When the patient schedules an appointment and is pre-registered

    The revenue cycle begins when the patient schedules and is pre-registered because the cycle starts with front-end access activities before any service. Claim submission, receipt of remittance advice, and final patient payment all occur later in the back-end stages of the cycle.

33. A practice creates a written compliance program with policies, staff training, auditing, and a process to report concerns. The primary purpose of such a program is to do which of the following?
    • Prevent, detect, and correct fraud, waste, and abuse
    • Increase the practice's charges to payers
    • Replace the need for an NPI
    • Eliminate the HIPAA Privacy Rule's requirements

    Correct answer: Prevent, detect, and correct fraud, waste, and abuse

    Preventing, detecting, and correcting fraud, waste, and abuse is the primary purpose of a compliance program. Such programs are not designed to raise charges, do not replace provider identifiers like the NPI, and operate alongside the Privacy Rule rather than eliminating its requirements.

34. Which of the following best illustrates the relationship between medical necessity and the revenue cycle's front-end activities?
    • Medical necessity is only checked after payment is posted
    • Confirming necessity during pre-service review helps ensure the eventual claim is payable
    • Medical necessity is determined solely by the clearinghouse
    • Medical necessity applies only to inpatient claims

    Correct answer: Confirming necessity during pre-service review helps ensure the eventual claim is payable

    Confirming necessity during pre-service review helps ensure the eventual claim is payable because front-end verification prevents downstream denials. Necessity is addressed before, not only after, payment; it is determined by clinical documentation rather than the clearinghouse; and it applies across care settings, not just inpatient.

35. A health care clearinghouse converts nonstandard data it receives into a standard electronic format and, in doing so, handles PHI. Under HIPAA, the clearinghouse is therefore subject to which obligation?
    • It is exempt from HIPAA because it does not treat patients
    • It must obtain an NPI for every patient
    • It must comply with HIPAA rules as a covered entity safeguarding PHI
    • It must waive all patient cost-sharing

    Correct answer: It must comply with HIPAA rules as a covered entity safeguarding PHI

    The clearinghouse must comply with HIPAA as a covered entity safeguarding PHI because clearinghouses are explicitly defined as covered entities. Not treating patients does not create an exemption, NPIs identify providers rather than patients, and HIPAA does not require waiving cost-sharing.

36. What is the primary purpose of an Advance Beneficiary Notice of Noncoverage (ABN) under Medicare?
    • To notify a beneficiary in advance that Medicare may not pay for a service so the patient can decide whether to accept financial responsibility
    • To automatically transfer a claim to the secondary payer
    • To assign the patient's benefits directly to the provider
    • To request prior authorization from a managed care plan

    Correct answer: To notify a beneficiary in advance that Medicare may not pay for a service so the patient can decide whether to accept financial responsibility

    Notifying the beneficiary in advance that Medicare may deny payment so the patient can decide whether to accept financial responsibility is the purpose of the ABN. The ABN does not forward claims to a secondary payer, assign benefits, or serve as a prior authorization request.

37. A provider expects Medicare to deny a screening service as not medically necessary. To bill the patient if Medicare denies, what must the provider do before performing the service?
    • Submit the claim with a coordination of benefits indicator
    • Obtain a National Provider Identifier for the patient
    • Wait for the remittance advice before scheduling the service
    • Have the patient sign an Advance Beneficiary Notice of Noncoverage

    Correct answer: Have the patient sign an Advance Beneficiary Notice of Noncoverage

    Having the patient sign an ABN before the service is required so the provider can bill the patient if Medicare denies the claim. A COB indicator addresses payer order, an NPI identifies providers not patients, and waiting for a remittance advice would occur only after billing, not before the service.

38. An ABN is most appropriately issued in which situation?
    • For every Medicaid service regardless of coverage
    • When a service is statutorily excluded and never covered by Medicare
    • When Medicare is expected to deny payment for a specific service that is usually covered but may not be in this case
    • Whenever a commercial PPO requires a referral

    Correct answer: When Medicare is expected to deny payment for a specific service that is usually covered but may not be in this case

    An ABN is appropriate when Medicare is expected to deny payment for a service that is usually covered but may not be in a particular case, often due to medical necessity. It is not used for routine Medicaid services, not required for statutorily excluded services (which use modifier GY instead), and is unrelated to commercial PPO referrals.

39. Which Medicare program does the Advance Beneficiary Notice of Noncoverage specifically apply to?
    • Original (fee-for-service) Medicare
    • Medicaid managed care
    • Workers' compensation
    • TRICARE

    Correct answer: Original (fee-for-service) Medicare

    The ABN applies to Original (fee-for-service) Medicare, alerting beneficiaries that the program may not pay. It is not a Medicaid managed care, workers' compensation, or TRICARE form, each of which has its own coverage and notification processes.

40. On the standard ABN form (CMS-R-131), why must the estimated cost of the service be listed?
    • To replace the need for an itemized statement
    • To set the Medicare fee schedule amount
    • To give the beneficiary the information needed to make an informed decision about accepting financial responsibility
    • To calculate the provider's RBRVS value

    Correct answer: To give the beneficiary the information needed to make an informed decision about accepting financial responsibility

    Listing the estimated cost gives the beneficiary the information needed to make an informed decision about accepting financial responsibility for the service. The ABN does not replace an itemized statement, set the fee schedule, or calculate relative value units.

41. When a properly executed ABN is on file and the beneficiary chose to receive the service, which modifier is typically appended to indicate an ABN was issued for an expected denial?
    • Modifier GA
    • Modifier 25
    • Modifier 59
    • Modifier 51

    Correct answer: Modifier GA

    Modifier GA indicates that a required ABN was issued for a service expected to be denied as not medically necessary. Modifiers 25, 59, and 51 address separate evaluation and management services, distinct procedural services, and multiple procedures, none of which signal an ABN.

42. A patient signs an ABN and selects the option to receive the service and have the claim submitted to Medicare. What is the provider obligated to do?
    • Refuse to perform the service until Medicare approves it
    • Bill the patient immediately without submitting any claim
    • Submit the claim to Medicare even though denial is expected
    • Forward the service directly to the patient's commercial plan

    Correct answer: Submit the claim to Medicare even though denial is expected

    When the patient selects the option to receive the service and have a claim filed, the provider must submit the claim to Medicare even though denial is expected, allowing for an official determination and appeal rights. The provider does not refuse the service, bill without a claim, or reroute it to a commercial plan.

43. What is the main goal of insurance verification before a patient's appointment?
    • To assign CPT codes for the planned procedure
    • To determine the DRG for an inpatient stay
    • To create the remittance advice
    • To confirm the patient's coverage, benefits, and eligibility so the claim can be paid

    Correct answer: To confirm the patient's coverage, benefits, and eligibility so the claim can be paid

    Confirming the patient's coverage, benefits, and eligibility so the claim can be paid is the main goal of insurance verification. Assigning CPT codes and determining DRGs are coding and reimbursement tasks, and a remittance advice is produced by the payer after adjudication, not during verification.

44. During insurance verification, which piece of information is most important to confirm to prevent a claim from being denied for lapsed coverage?
    • The patient's preferred pharmacy
    • The policy's effective and termination dates
    • The provider's RBRVS conversion factor
    • The clearinghouse used by the practice

    Correct answer: The policy's effective and termination dates

    Confirming the policy's effective and termination dates verifies that coverage is active on the date of service, preventing denials for lapsed coverage. A preferred pharmacy, the RBRVS conversion factor, and the practice's clearinghouse do not establish whether the patient's coverage is in force.

45. A front-desk specialist verifies a new patient's insurance and learns the plan requires the patient to use in-network providers. Failing to act on this information would most likely result in which outcome?
    • A timely filing denial
    • Higher out-of-pocket costs or reduced benefits for out-of-network care
    • A HIPAA breach
    • An automatic crossover to Medicaid

    Correct answer: Higher out-of-pocket costs or reduced benefits for out-of-network care

    If the network requirement is ignored, the patient would likely face higher out-of-pocket costs or reduced benefits for out-of-network care. Timely filing concerns submission deadlines, a HIPAA breach concerns PHI disclosure, and a crossover involves automatic forwarding to a secondary payer, none of which stem from network status.

46. What does coordination of benefits (COB) determine when a patient has more than one insurance policy?
    • Which plan is primary and which is secondary so benefits are not duplicated
    • The CPT code for the most expensive service
    • Whether an ABN is required
    • The patient's place of service code

    Correct answer: Which plan is primary and which is secondary so benefits are not duplicated

    Coordination of benefits determines which plan is primary and which is secondary so that combined payments do not exceed the allowed charge and benefits are not duplicated. COB does not assign CPT codes, trigger an ABN, or set the place of service code.

47. Under the birthday rule used in coordination of benefits, how is the primary plan determined for a dependent child covered by both parents' plans?
    • The parent who is older is always primary
    • The plan of the parent whose birthday falls earlier in the calendar year is primary
    • The mother's plan is always primary
    • The plan with the higher premium is primary

    Correct answer: The plan of the parent whose birthday falls earlier in the calendar year is primary

    The birthday rule makes primary the plan of the parent whose birthday (month and day) falls earlier in the calendar year, not the older parent. The rule does not default to the mother's plan or the plan with the higher premium; it compares the calendar position of the birthdays.

48. A working-age patient has coverage through their own employer and is also listed as a dependent on a spouse's plan. For the patient's own claim, which plan is generally primary?
    • The spouse's plan as the dependent coverage
    • The plan with the lower deductible
    • The patient's own employer plan
    • Whichever plan the patient chooses each visit

    Correct answer: The patient's own employer plan

    For a patient's own claim, the plan where the patient is the subscriber (their own employer plan) is generally primary, and the plan covering them as a dependent is secondary. Coordination order is set by COB rules rather than deductible size or patient preference at each visit.

49. When coordination of benefits applies, what happens after the primary payer processes the claim?
    • The patient is automatically released from all responsibility
    • The provider must reissue an ABN
    • The claim is closed with no further billing
    • The claim and primary payer's payment information are submitted to the secondary payer

    Correct answer: The claim and primary payer's payment information are submitted to the secondary payer

    After the primary payer processes the claim, the claim along with the primary payment information is submitted to the secondary payer to consider any remaining balance. The patient is not automatically released from responsibility, no ABN is reissued, and the claim is not closed until secondary processing is complete.

50. Medicare Part A primarily provides coverage for which type of services?
    • Outpatient physician office visits
    • Prescription drug benefits
    • Inpatient hospital care, skilled nursing facility care, and hospice
    • Routine dental cleanings

    Correct answer: Inpatient hospital care, skilled nursing facility care, and hospice

    Medicare Part A primarily covers inpatient hospital care, skilled nursing facility care, hospice, and some home health services. Outpatient physician services fall under Part B, prescription drugs fall under Part D, and routine dental care is generally not covered by Original Medicare.

51. Medicare Part B is best described as coverage for which of the following?
    • Inpatient hospital room and board only
    • Long-term custodial nursing home care
    • Stand-alone prescription drug plans
    • Outpatient services, physician visits, and durable medical equipment

    Correct answer: Outpatient services, physician visits, and durable medical equipment

    Medicare Part B covers outpatient services, physician visits, preventive care, and durable medical equipment. Inpatient room and board is Part A, custodial long-term care is generally not a Medicare benefit, and stand-alone drug plans are Part D.

52. A Medicare beneficiary receives a physician office visit and an outpatient X-ray on the same day. Which part of Medicare is the appropriate payer for these services?
    • Part A
    • Part D
    • Part B
    • Part C only

    Correct answer: Part B

    Part B is the appropriate payer for physician office visits and outpatient diagnostic services such as an X-ray. Part A covers inpatient facility care, Part D covers prescription drugs, and Part C (Medicare Advantage) is an alternative way to receive benefits rather than the default fee-for-service payer here.

53. Which statement accurately distinguishes how Medicare Part A and Part B are funded for most beneficiaries?
    • Both require a monthly premium for everyone
    • Part A is usually premium-free for those with sufficient work history, while Part B requires a monthly premium
    • Part B is always premium-free and Part A always has a premium
    • Neither requires any cost-sharing from beneficiaries

    Correct answer: Part A is usually premium-free for those with sufficient work history, while Part B requires a monthly premium

    Part A is usually premium-free for beneficiaries with sufficient Medicare-covered work history, while Part B generally requires a monthly premium. It is not true that both require premiums for everyone, that Part B is always free, or that beneficiaries face no cost-sharing.

54. Medicaid is best described as which type of program?
    • A federal-only program for individuals age 65 and older
    • A private commercial insurance plan
    • An employer-sponsored health savings account
    • A joint federal and state program providing coverage primarily for low-income individuals

    Correct answer: A joint federal and state program providing coverage primarily for low-income individuals

    Medicaid is a joint federal and state program that provides health coverage primarily for low-income individuals and families. It is not federal-only or age-based like Medicare, not a private commercial plan, and not an employer-sponsored health savings account.

55. When a patient is covered by both Medicare and Medicaid, what is Medicaid's general role in the payer hierarchy?
    • Medicaid is always the primary payer
    • Medicaid is the payer of last resort, paying after other coverage
    • Medicaid pays equally with Medicare at the same time
    • Medicaid refuses to pay any claim with Medicare involved

    Correct answer: Medicaid is the payer of last resort, paying after other coverage

    Medicaid is generally the payer of last resort, meaning it pays only after Medicare and any other coverage has been applied. It is not the primary payer, does not split payment equally, and does not refuse claims simply because Medicare is involved.

56. Because Medicaid eligibility can change frequently, what should a billing specialist do before each date of service for a Medicaid patient?
    • Issue an ABN for every visit
    • Assign the patient a National Provider Identifier
    • Verify the patient's current Medicaid eligibility
    • Submit the claim to a clearinghouse first

    Correct answer: Verify the patient's current Medicaid eligibility

    Verifying the patient's current Medicaid eligibility before each date of service is necessary because Medicaid eligibility can change monthly. Issuing an ABN is a Medicare process, an NPI identifies providers, and routing through a clearinghouse occurs during submission rather than eligibility checking.

57. Which item is a patient cost-sharing amount that is a fixed dollar amount paid at the time of service for a covered visit?
    • Coinsurance
    • Deductible
    • Copayment
    • Premium

    Correct answer: Copayment

    A copayment is a fixed dollar amount paid at the time of service for a covered visit. Coinsurance is a percentage of the allowed amount, a deductible is the amount paid before the plan begins paying, and a premium is the recurring charge to maintain coverage.

58. A plan has a $1,500 annual deductible. What does this mean for the patient?
    • The patient pays $1,500 each visit
    • The patient must pay $1,500 in covered costs before the plan begins paying its share
    • The plan pays the first $1,500 of every claim
    • The patient owes a $1,500 monthly premium

    Correct answer: The patient must pay $1,500 in covered costs before the plan begins paying its share

    An annual deductible of $1,500 means the patient must pay that amount in covered costs before the plan begins paying its share. It is not a per-visit charge, is not paid first by the plan, and is distinct from a monthly premium.

59. A patient's plan pays 80% of the allowed amount after the deductible is met, and the patient pays the remaining 20%. The 20% the patient owes is known as which of the following?
    • A copayment
    • A premium
    • Coinsurance
    • A write-off

    Correct answer: Coinsurance

    The 20% the patient pays after the deductible is coinsurance, a percentage of the allowed amount shared between the plan and patient. A copayment is a flat fee, a premium maintains coverage, and a write-off is an adjustment the provider absorbs.

60. A service has an allowed amount of $200. The patient has already met the deductible and has 20% coinsurance. How much is the patient responsible for?
    • $40
    • $200
    • $160
    • $0

    Correct answer: $40

    The patient owes $40, calculated as 20% of the $200 allowed amount once the deductible is met. The plan pays the remaining 80%, or $160, so the patient is not responsible for the full $200 or for nothing.

61. In a Health Maintenance Organization (HMO), what is typically required before a member sees a specialist?
    • A referral from the member's primary care physician
    • An Advance Beneficiary Notice
    • A coordination of benefits statement
    • A signed assignment of benefits at the specialist's office

    Correct answer: A referral from the member's primary care physician

    An HMO typically requires a referral from the member's primary care physician before seeing a specialist. An ABN is a Medicare notice, a coordination of benefits statement addresses multiple payers, and an assignment of benefits directs payment rather than authorizing specialist access.

62. How does a Preferred Provider Organization (PPO) generally differ from an HMO?
    • A PPO never covers any out-of-network care
    • A PPO requires a primary care physician referral for all visits
    • A PPO allows members to see out-of-network providers, usually at a higher cost, often without a referral
    • A PPO is only available to Medicare beneficiaries

    Correct answer: A PPO allows members to see out-of-network providers, usually at a higher cost, often without a referral

    A PPO allows members to see out-of-network providers, usually at higher out-of-pocket cost, and often does not require referrals. PPOs do cover out-of-network care, do not mandate referrals for every visit, and are not limited to Medicare beneficiaries.

63. A patient enrolled in an HMO sees an out-of-network specialist without a referral for a non-emergency service. What is the most likely billing outcome?
    • The HMO pays the full amount automatically
    • The claim is automatically crossed over to Medicaid
    • The service may be denied, leaving the patient responsible for the cost
    • An ABN must be retroactively issued by the HMO

    Correct answer: The service may be denied, leaving the patient responsible for the cost

    Because HMOs restrict coverage to in-network care with required referrals, the out-of-network specialist service may be denied, leaving the patient responsible for the cost. The HMO would not pay automatically, the claim would not cross over to Medicaid, and an ABN is a Medicare process, not an HMO function.

64. What is prior authorization in the context of payer requirements?
    • Approval obtained from the payer before a service is rendered to confirm it will be covered
    • A patient's signature allowing release of medical records
    • A document explaining how a claim was adjudicated
    • The deadline by which a claim must be filed

    Correct answer: Approval obtained from the payer before a service is rendered to confirm it will be covered

    Prior authorization is approval obtained from the payer before a service is rendered to confirm the service will be covered. It is not a records-release authorization, an adjudication explanation like a remittance advice, or a filing deadline such as the timely filing limit.

65. A physician orders an expensive imaging study that the patient's plan requires be approved in advance. If the staff schedules and performs the study without obtaining this approval, what is the most likely consequence?
    • The claim will be paid at a higher rate
    • The claim will be denied for lack of prior authorization
    • The patient automatically qualifies for Medicaid
    • The provider must issue a remittance advice

    Correct answer: The claim will be denied for lack of prior authorization

    Performing a service that requires advance approval without obtaining prior authorization most likely results in a denial for lack of prior authorization. Skipping authorization does not increase payment, does not qualify the patient for Medicaid, and the remittance advice is generated by the payer, not the provider.

66. Which of the following services most commonly requires prior authorization from a payer?
    • A routine established-patient office visit
    • An advanced imaging procedure such as an MRI or a planned surgery
    • Taking a patient's blood pressure
    • Updating a patient's demographic information

    Correct answer: An advanced imaging procedure such as an MRI or a planned surgery

    Advanced imaging such as an MRI or a planned surgery commonly requires prior authorization because of cost and medical-necessity review. Routine office visits, basic vital-sign measurement, and administrative demographic updates typically do not require payer pre-approval.

67. What does an assignment of benefits (AOB) authorize?
    • The payer to send payment directly to the provider rather than the patient
    • The provider to share PHI with any third party
    • The patient to choose a primary care physician
    • The payer to waive the patient's deductible

    Correct answer: The payer to send payment directly to the provider rather than the patient

    An assignment of benefits authorizes the payer to send payment directly to the provider rather than to the patient. It does not grant unlimited PHI sharing, select a primary care physician, or waive the patient's deductible.

68. A patient signs an assignment of benefits at registration. How does this affect claim payment?
    • The patient must pay the full charge and seek reimbursement personally
    • The claim is automatically appealed if denied
    • Coordination of benefits is no longer required
    • Insurance payment for the claim is sent directly to the provider

    Correct answer: Insurance payment for the claim is sent directly to the provider

    When a patient signs an assignment of benefits, the insurance payment for the claim is sent directly to the provider. The patient is not required to pay in full and seek reimbursement, the AOB does not trigger automatic appeals, and coordination of benefits is still applied when multiple plans exist.

69. On the CMS-1500 claim form, the field indicating whether benefits are assigned to the provider relates to which concept?
    • Coordination of benefits
    • Prior authorization
    • Assignment of benefits
    • Advance beneficiary notice

    Correct answer: Assignment of benefits

    The field indicating whether benefits are assigned to the provider reflects the assignment of benefits, which directs payment to the provider. Coordination of benefits addresses payer order, prior authorization is pre-service approval, and an advance beneficiary notice is a Medicare denial notice.

70. A billing specialist confirms a commercial patient's deductible has not yet been met for the year. What is the most appropriate next step regarding patient responsibility?
    • Bill the entire allowed amount to the secondary payer
    • Inform the patient they may owe the cost up to the remaining deductible amount
    • Issue an ABN to the commercial patient
    • Forward the claim to Medicaid as primary

    Correct answer: Inform the patient they may owe the cost up to the remaining deductible amount

    If the deductible has not been met, the appropriate step is to inform the patient they may owe the cost up to the remaining deductible amount. Billing a secondary payer skips proper order, an ABN is a Medicare tool, and Medicaid is not automatically primary for a commercial patient.

71. Why is it important to identify whether a patient has primary and secondary coverage during the eligibility process?
    • To determine the correct order claims should be submitted to payers
    • To select the appropriate CPT modifier
    • To set the DRG weight for the encounter
    • To generate the patient's NPI

    Correct answer: To determine the correct order claims should be submitted to payers

    Identifying primary and secondary coverage during eligibility determines the correct order claims should be submitted, which is essential to coordination of benefits. It does not select CPT modifiers, set DRG weights, or generate an NPI, which are coding, reimbursement, and provider-identification functions.

72. A patient presents an insurance card and the specialist calls the payer to confirm the plan is active and covers the planned service. This activity is best described as which of the following?
    • Claim adjudication
    • Eligibility and benefits verification
    • Payment posting
    • Remittance processing

    Correct answer: Eligibility and benefits verification

    Confirming that the plan is active and covers the planned service is eligibility and benefits verification, a front-end payer-requirement task. Claim adjudication, payment posting, and remittance processing all occur after a claim is submitted, not during pre-service verification.

73. What information is typically found on a patient's insurance identification card that supports verification and claim submission?
    • The patient's CPT and ICD-10-CM codes
    • The member ID, group number, and payer contact information
    • The provider's RBRVS conversion factor
    • The remittance advice control number

    Correct answer: The member ID, group number, and payer contact information

    An insurance ID card typically shows the member ID, group number, and payer contact information needed for verification and claim submission. Procedure and diagnosis codes are assigned by coders, the RBRVS conversion factor is a reimbursement value, and a remittance advice control number appears after adjudication.

74. For a beneficiary who declines to sign a required ABN before a service expected to be denied, what is the recommended provider action?
    • Perform the service and guarantee Medicare payment
    • Annotate that the beneficiary refused to sign and have a witness sign the ABN, then decide whether to provide the service
    • Automatically bill the patient the full charge without a claim
    • Submit the claim to Medicaid as primary

    Correct answer: Annotate that the beneficiary refused to sign and have a witness sign the ABN, then decide whether to provide the service

    When a beneficiary refuses to sign a required ABN, the recommended action is to annotate the refusal and have a witness sign, then decide whether to furnish the service. The provider cannot guarantee Medicare payment, should not skip the claim process, and cannot make Medicaid primary by default.

75. A patient covered by an employer PPO also has Medicare due to age and is actively working for an employer with 20 or more employees. Under Medicare Secondary Payer rules, which plan is generally primary?
    • Medicare is always primary for anyone age 65 or older
    • The employer group health plan is primary and Medicare is secondary
    • The patient chooses which plan is primary each visit
    • Neither plan pays until the deductible is satisfied

    Correct answer: The employer group health plan is primary and Medicare is secondary

    For an actively working beneficiary whose employer has 20 or more employees, the employer group health plan is generally primary and Medicare is secondary under Medicare Secondary Payer rules. Medicare is not automatically primary at 65, payer order is not chosen per visit, and the deductible does not change which plan is primary.

76. A managed care plan denies a specialist visit because no referral was on file. To prevent this denial in the future, the billing workflow should ensure which step occurs during eligibility?
    • Confirming referral and authorization requirements for the patient's plan type
    • Appending modifier 59 to the claim
    • Issuing a remittance advice to the patient
    • Assigning a place of service code for the home

    Correct answer: Confirming referral and authorization requirements for the patient's plan type

    Confirming referral and authorization requirements for the patient's plan type during eligibility prevents managed-care denials for missing referrals. Modifier 59 is a coding action, a remittance advice is issued by the payer, and a place of service code reports where care occurred rather than securing a referral.

77. Which statement correctly describes the relationship between a premium and the other patient cost-sharing amounts?
    • A premium is the same as a deductible
    • A premium is paid per visit like a copayment
    • A premium is the recurring amount paid to keep coverage active, separate from deductibles, copays, and coinsurance
    • A premium is the percentage paid after the deductible

    Correct answer: A premium is the recurring amount paid to keep coverage active, separate from deductibles, copays, and coinsurance

    A premium is the recurring amount paid to keep coverage active and is separate from the deductible, copayment, and coinsurance owed at the point of care. A premium is not the same as a deductible, is not paid per visit, and is not the post-deductible percentage, which is coinsurance.

78. A new Medicaid patient's coverage cannot be confirmed as active on the date of service during verification. What is the most appropriate billing-specialist action?
    • Submit the claim anyway and assume it will pay
    • Resolve the eligibility issue before or at the visit to avoid a denial for inactive coverage
    • Issue an ABN for the Medicaid service
    • Forward the patient's record to a clearinghouse for approval

    Correct answer: Resolve the eligibility issue before or at the visit to avoid a denial for inactive coverage

    When Medicaid coverage cannot be confirmed active, the appropriate action is to resolve the eligibility issue before or at the visit to avoid a denial for inactive coverage. Submitting blindly risks denial, an ABN is a Medicare process, and a clearinghouse routes claims rather than approving eligibility.

79. A patient has both a primary commercial plan and a secondary plan. The primary pays part of the allowed amount and applies the rest to the deductible. What should the billing specialist do next?
    • Write off the remaining balance immediately
    • Submit the claim and the primary remittance information to the secondary payer
    • Issue an ABN to the patient
    • Resubmit the claim to the primary payer unchanged

    Correct answer: Submit the claim and the primary remittance information to the secondary payer

    After the primary payer processes the claim, the next step is to submit the claim with the primary remittance information to the secondary payer to consider the remaining balance. Writing off the balance prematurely, issuing an ABN, or resubmitting unchanged to the primary would all bypass proper coordination of benefits.

80. A provider participates with a payer and accepts assignment. How does accepting assignment relate to the assignment of benefits and patient billing?
    • Accepting assignment means the provider will balance bill the patient for the full charge
    • The provider agrees to accept the allowed amount as payment in full and bill the patient only for applicable cost-sharing
    • Accepting assignment cancels the patient's deductible
    • Accepting assignment requires an ABN for every claim

    Correct answer: The provider agrees to accept the allowed amount as payment in full and bill the patient only for applicable cost-sharing

    Accepting assignment means the provider agrees to accept the payer's allowed amount as payment in full and bills the patient only for applicable deductible, copay, or coinsurance. It does not permit balance billing the full charge, does not cancel the deductible, and does not require an ABN on every claim.

81. A specialist's office obtains prior authorization for a procedure, but the approval number is later found to be tied to a different service than the one performed. What is the most likely result when the claim is processed?
    • The claim pays in full because any authorization number was on file
    • The payer denies the claim because the authorization does not match the service rendered
    • The patient is automatically enrolled in an HMO
    • The deductible is waived for the encounter

    Correct answer: The payer denies the claim because the authorization does not match the service rendered

    The payer denies the claim because the authorization on file does not match the service rendered, since prior authorization is service-specific. Merely having any authorization number does not guarantee payment, the situation does not enroll the patient in an HMO, and it does not waive the deductible.

82. Which code set is used to report patient diagnoses and the reasons for an encounter?
    • ICD-10-CM
    • CPT Category I
    • HCPCS Level II
    • Place of service codes

    Correct answer: ICD-10-CM

    ICD-10-CM is correct because it is the diagnosis code set used to report conditions, signs, symptoms, and reasons for an encounter. CPT Category I and HCPCS Level II report procedures, services, and supplies rather than diagnoses, and place of service codes identify where care was delivered.

83. According to the ICD-10-CM Official Guidelines, what should be done when a diagnosis is documented as a confirmed condition for an outpatient encounter?
    • Code only signs and symptoms instead of the diagnosis
    • Code the confirmed condition to the highest level of specificity supported by the documentation
    • Use an unspecified code regardless of available detail
    • Assign a procedure code in place of the diagnosis

    Correct answer: Code the confirmed condition to the highest level of specificity supported by the documentation

    Coding the confirmed condition to the highest level of specificity supported by the documentation is correct because ICD-10-CM guidelines require the most precise code available. Defaulting to symptoms or unspecified codes when detail exists is improper, and a diagnosis is never replaced by a procedure code.

84. Under ICD-10-CM outpatient coding guidelines, how should a coder handle a condition documented as probable, suspected, or rule-out?
    • Code the uncertain diagnosis as if it were confirmed
    • Omit any diagnosis code from the claim
    • Code the signs, symptoms, or reason for the visit instead of the uncertain diagnosis
    • Assign a Z code for a routine examination

    Correct answer: Code the signs, symptoms, or reason for the visit instead of the uncertain diagnosis

    Coding the signs, symptoms, or reason for the visit is correct because outpatient guidelines prohibit reporting uncertain (probable, suspected, rule-out) diagnoses as if established. Coding the uncertain condition as confirmed is the inpatient rule, omitting a diagnosis is incorrect, and a routine-exam Z code does not fit a symptomatic visit.

85. In ICD-10-CM, what is the purpose of the seventh character used with certain codes, such as those for fractures?
    • It identifies the place of service
    • It reports the supervising provider
    • It sets the reimbursement amount
    • It indicates the episode of care, such as initial, subsequent, or sequela

    Correct answer: It indicates the episode of care, such as initial, subsequent, or sequela

    The seventh character indicates the episode of care, such as initial encounter, subsequent encounter, or sequela, which is required for many injury and external-cause codes. It does not report the place of service, the provider, or any payment amount, which are conveyed elsewhere.

86. When two ICD-10-CM guidelines or instructional notes conflict, which resource takes precedence?
    • The instructional notes in the Tabular List and the conventions of the classification
    • The coder's personal preference
    • The order in which charges were entered
    • Whichever code produces a higher payment

    Correct answer: The instructional notes in the Tabular List and the conventions of the classification

    The instructional notes in the Tabular List and the conventions of the classification take precedence because ICD-10-CM rules are hierarchical and instructional notes guide correct assignment. Personal preference, charge-entry order, and payment-maximizing choices are never valid bases for code selection.

87. Where should a coder always begin when locating an ICD-10-CM diagnosis code?
    • In the Tabular List by code number
    • In the Alphabetic Index using the main term
    • On the fee schedule
    • In the CPT index

    Correct answer: In the Alphabetic Index using the main term

    A coder should begin in the Alphabetic Index using the main term, then verify the code in the Tabular List. Starting in the Tabular List by number skips the index step, the fee schedule is a payment tool, and the CPT index is for procedures rather than diagnoses.

88. A physician documents type 2 diabetes mellitus with diabetic chronic kidney disease. According to ICD-10-CM combination-code guidelines, how should this be reported?
    • With one code for diabetes and never the kidney condition
    • By coding only the kidney disease and ignoring the diabetes
    • With a single combination code that captures the diabetes and its kidney manifestation
    • By assigning a CPT code for the diabetes

    Correct answer: With a single combination code that captures the diabetes and its kidney manifestation

    A single combination code that captures the diabetes and its kidney manifestation is correct because ICD-10-CM provides combination codes that link diabetes with its complications. Reporting only one condition misses the documented relationship, and a CPT procedure code cannot represent a diagnosis.

89. What does an Excludes1 note in ICD-10-CM indicate?
    • The two conditions may be coded together when both are present
    • The code requires an additional seventh character
    • The code is exempt from medical necessity
    • The excluded code should never be reported with the code where the note appears because the conditions cannot occur together

    Correct answer: The excluded code should never be reported with the code where the note appears because the conditions cannot occur together

    An Excludes1 note means the excluded code should never be reported together with the code where the note appears because the two conditions are mutually exclusive. It is not the same as Excludes2, which allows both codes, and it has nothing to do with seventh characters or medical-necessity exemptions.

90. What type of codes does the Current Procedural Terminology (CPT) system primarily report?
    • Medical procedures and professional services
    • Patient diagnoses and conditions
    • Geographic locations of services
    • Insurance plan types

    Correct answer: Medical procedures and professional services

    CPT primarily reports medical procedures and professional services performed by providers. Diagnoses are reported with ICD-10-CM, locations are reported with place of service codes, and plan types are not part of any procedure or diagnosis code set.

91. How many digits make up a standard CPT Category I code?
    • Three digits
    • Five digits
    • Four digits
    • Seven digits

    Correct answer: Five digits

    A standard CPT Category I code is five digits. Diagnosis codes and other systems use different lengths, but the foundational CPT Category I structure is a five-digit numeric code.

92. Which organization develops and maintains the CPT code set?
    • The Centers for Medicare & Medicaid Services
    • The Food and Drug Administration
    • The American Medical Association
    • The National Healthcareer Association

    Correct answer: The American Medical Association

    The American Medical Association develops and maintains the CPT code set. CMS maintains HCPCS Level II, the FDA regulates drugs and devices, and the NHA is a certification body, none of which author CPT.

93. A symbol resembling a bullet (a filled dot) appears next to a CPT code in the codebook. What does this symbol indicate?
    • The code has been deleted
    • The code includes moderate sedation
    • The code is exempt from modifier 51
    • The code is a new code added in the current edition

    Correct answer: The code is a new code added in the current edition

    A filled-dot (bullet) symbol indicates that the code is new in the current edition of CPT. A revised code uses a different symbol, exemption from modifier 51 and inclusion of moderate sedation are shown by separate symbols, and deletions are handled by removal with notations.

94. Which of the following is a CPT Category I code section?
    • Surgery
    • Place of service
    • Revenue codes
    • Diagnosis-related groups

    Correct answer: Surgery

    Surgery is one of the six main CPT Category I sections, along with Evaluation and Management, Anesthesia, Radiology, Pathology and Laboratory, and Medicine. Place of service, revenue codes, and diagnosis-related groups are not CPT sections.

95. What is the function of CPT Category II codes?
    • To report primary procedures for payment
    • To track performance measurement and quality data
    • To replace ICD-10-CM diagnosis codes
    • To indicate the place of service

    Correct answer: To track performance measurement and quality data

    CPT Category II codes are supplemental tracking codes used for performance measurement and quality data. They are not used to obtain payment for procedures, do not replace diagnosis codes, and do not report the place of service.

96. A coder needs to report a surgical procedure performed during an outpatient visit. Which code set provides the appropriate procedure code?
    • ICD-10-CM
    • Place of service codes
    • CPT
    • The patient's insurance card

    Correct answer: CPT

    CPT provides the appropriate procedure code for the surgical service. ICD-10-CM reports the diagnosis, place of service codes report where care occurred, and an insurance card supplies coverage information rather than procedure codes.

97. When indented CPT code descriptions appear under a parent code, how should the indented description be read?
    • It stands completely alone with no relationship to the parent
    • It replaces the parent code entirely
    • It can only be used with a modifier
    • It includes the common portion of the parent code's description up to the semicolon

    Correct answer: It includes the common portion of the parent code's description up to the semicolon

    An indented CPT description includes the common portion of the parent code's wording that appears before the semicolon, which is then completed by the indented text. The indented code does not stand alone, does not replace the parent, and does not require a modifier merely because it is indented.

98. What does the HCPCS Level II code set primarily report that CPT generally does not?
    • Supplies, durable medical equipment, drugs, and certain services
    • Patient diagnoses
    • Place of service
    • Insurance eligibility

    Correct answer: Supplies, durable medical equipment, drugs, and certain services

    HCPCS Level II primarily reports supplies, durable medical equipment, drugs, and certain services not found in CPT. Diagnoses are reported with ICD-10-CM, place of service has its own codes, and insurance eligibility is a verification function rather than a code set.

99. What is the structure of a HCPCS Level II code?
    • Five numeric digits
    • A single alphabetic letter followed by four numeric digits
    • Three numeric digits and a decimal
    • Two letters followed by three numbers

    Correct answer: A single alphabetic letter followed by four numeric digits

    A HCPCS Level II code consists of a single alphabetic letter followed by four numeric digits. Five all-numeric digits describe CPT Category I, and the other formats do not match the HCPCS Level II alphanumeric structure.

100. Which agency is responsible for maintaining the HCPCS Level II code set?
     • The American Medical Association
     • The American Hospital Association
     • The Centers for Medicare & Medicaid Services
     • The Office of Inspector General

     Correct answer: The Centers for Medicare & Medicaid Services

     The Centers for Medicare & Medicaid Services maintains the HCPCS Level II code set. The American Medical Association maintains CPT, the American Hospital Association maintains revenue and UB-related coding guidance, and the OIG focuses on program integrity rather than code maintenance.

101. A provider dispenses a wheelchair and a quantity of sterile gauze to a patient. Which code set is most appropriate to report these supplies and equipment?
     • CPT Category I
     • ICD-10-CM
     • Category II performance codes
     • HCPCS Level II

     Correct answer: HCPCS Level II

     HCPCS Level II is most appropriate for reporting supplies, durable medical equipment such as a wheelchair, and items like gauze. CPT Category I reports procedures, ICD-10-CM reports diagnoses, and Category II codes track quality measures rather than supplies.

102. A physician administers an injectable drug in the office. Which code set is typically used to report the specific drug administered?
     • HCPCS Level II J codes
     • ICD-10-CM
     • Place of service codes
     • CPT Category II codes

     Correct answer: HCPCS Level II J codes

     HCPCS Level II J codes are typically used to report the specific drug administered. ICD-10-CM reports the diagnosis, place of service codes report the setting, and Category II codes capture quality data rather than the drug itself.

103. What is the primary purpose of a CPT or HCPCS modifier?
     • To change the meaning of a diagnosis code
     • To provide additional information about a service without changing the code's basic definition
     • To assign the patient's place of service
     • To set the timely filing deadline

     Correct answer: To provide additional information about a service without changing the code's basic definition

     A modifier provides additional information about a service or procedure without changing the code's basic definition, such as indicating a service was altered by a specific circumstance. Modifiers do not change diagnosis codes, assign place of service, or set filing deadlines.

104. How many characters make up a CPT modifier?
     • One character
     • Three characters
     • Two characters
     • Five characters

     Correct answer: Two characters

     A CPT modifier is two characters. CPT base codes are five characters, but the appended modifier that further describes the service is a two-character addition.

105. A bilateral procedure is performed on both knees during the same session. Which CPT modifier reports that the procedure was performed bilaterally?
     • Modifier 25
     • Modifier 59
     • Modifier 26
     • Modifier 50

     Correct answer: Modifier 50

     Modifier 50 reports a bilateral procedure performed on both sides during the same session. Modifier 25 indicates a separate E/M service, modifier 59 indicates a distinct procedural service, and modifier 26 indicates the professional component only.

106. When multiple surgical procedures are performed by the same provider during the same session, which CPT modifier is appended to the secondary procedures?
     • Modifier 51
     • Modifier 25
     • Modifier 50
     • Modifier 76

     Correct answer: Modifier 51

     Modifier 51 is appended to secondary procedures when multiple procedures are performed in the same session by the same provider. Modifier 25 applies to a separate E/M service, modifier 50 reports bilateral procedures, and modifier 76 indicates a repeat procedure by the same provider.

107. A radiologist interprets an X-ray taken with equipment owned by the hospital. Which modifier reports only the professional component of the service?
     • Modifier TC
     • Modifier 26
     • Modifier 59
     • Modifier 50

     Correct answer: Modifier 26

     Modifier 26 reports only the professional component, such as the physician's interpretation, when the technical resources are provided by another entity. Modifier TC reports the technical component, modifier 59 indicates a distinct service, and modifier 50 reports a bilateral procedure.

108. What is the primary purpose of CPT modifier 25?
     • To indicate a bilateral procedure
     • To report a repeat laboratory test
     • To report a significant, separately identifiable evaluation and management service on the same day as a procedure
     • To indicate a discontinued procedure

     Correct answer: To report a significant, separately identifiable evaluation and management service on the same day as a procedure

     Modifier 25 reports a significant, separately identifiable E/M service performed by the same provider on the same day as a procedure or other service. It does not indicate a bilateral procedure, a repeat lab test, or a discontinued procedure, which are reported with other modifiers.

109. A patient presents for a scheduled lesion removal, and during the same visit the physician evaluates a new, unrelated complaint requiring a separate workup. Which modifier supports billing the separate E/M service?
     • Modifier 59
     • Modifier 51
     • Modifier 50
     • Modifier 25

     Correct answer: Modifier 25

     Modifier 25 supports billing the significant, separately identifiable E/M service furnished on the same day as the lesion removal because the new complaint required work beyond the procedure. Modifier 59 applies to distinct procedures, modifier 51 to multiple procedures, and modifier 50 to bilateral procedures.

110. Modifier 25 is appended to which type of code?
     • An evaluation and management code
     • A diagnosis code
     • A place of service code
     • A HCPCS supply code

     Correct answer: An evaluation and management code

     Modifier 25 is appended to an evaluation and management code to show it was significant and separately identifiable from a same-day procedure. It is not appended to a diagnosis code, a place of service code, or a supply code.

111. Which scenario would represent inappropriate use of modifier 25?
     • A separate problem requiring a distinct history, exam, and decision making on the same day as a minor procedure
     • Appending it routinely to every office visit billed with any procedure even when no separate E/M work was performed
     • A new condition evaluated alongside a planned procedure
     • A significant evaluation that goes beyond the usual pre-procedure assessment

     Correct answer: Appending it routinely to every office visit billed with any procedure even when no separate E/M work was performed

     Routinely appending modifier 25 to every visit with a procedure when no separate, significant E/M work occurred is inappropriate because the modifier requires distinct, documented E/M effort. The other scenarios describe genuine separately identifiable evaluations that legitimately support the modifier.

112. What is the primary purpose of CPT modifier 59?
     • To report a separate E/M service on the same day
     • To indicate the technical component only
     • To identify a distinct procedural service that is not normally reported together with another service
     • To report a bilateral procedure

     Correct answer: To identify a distinct procedural service that is not normally reported together with another service

     Modifier 59 identifies a distinct procedural service, such as a different session, site, or procedure, that is not normally reported together with another service. It does not report a separate E/M service, the technical component, or a bilateral procedure, which use other modifiers.

113. Modifier 59 is most closely associated with overriding which type of coding restriction when services are truly distinct?
     • Timely filing limits
     • Place of service requirements
     • Diagnosis specificity rules
     • National Correct Coding Initiative edits that would otherwise bundle two services

     Correct answer: National Correct Coding Initiative edits that would otherwise bundle two services

     Modifier 59 is most closely associated with overriding National Correct Coding Initiative edits that would otherwise bundle two services, when documentation shows the services were genuinely distinct. It is unrelated to timely filing, place of service, or diagnosis specificity.

114. Two procedures normally bundled together were performed at separate anatomic sites during the same encounter, and documentation supports their distinctness. Which modifier is appropriate?
     • Modifier 59
     • Modifier 25
     • Modifier 50
     • Modifier 26

     Correct answer: Modifier 59

     Modifier 59 is appropriate because it reports a distinct procedural service performed at a separate site that documentation supports as independent. Modifier 25 applies to E/M services, modifier 50 to bilateral procedures, and modifier 26 to the professional component.

115. Which practice describes misuse of modifier 59 that could be flagged as improper coding?
     • Appending it when two procedures are performed at clearly separate sites
     • Appending it to bypass a coding edit when the services were actually part of the same procedure
     • Appending it for procedures performed in distinct sessions
     • Appending it when documentation clearly supports two independent procedures

     Correct answer: Appending it to bypass a coding edit when the services were actually part of the same procedure

     Appending modifier 59 to bypass a coding edit when the services were actually part of the same procedure is misuse because the modifier requires a genuinely distinct service. The other options describe legitimate situations where the services are truly separate.

116. What does evaluation and management (E/M) coding describe?
     • Surgical procedures performed in an operating room
     • The supplies dispensed during a visit
     • Cognitive services such as patient visits, assessments, and care management
     • The diagnosis assigned to the encounter

     Correct answer: Cognitive services such as patient visits, assessments, and care management

     E/M coding describes cognitive services such as patient visits, assessments, and care management provided by clinicians. It does not represent surgical procedures, supplies, or the diagnosis, which are captured by other code sets.

117. Under current CPT E/M office visit guidelines, the level of service for an established office visit may be selected based on which two factors?
     • The patient's age and gender
     • The place of service and the payer
     • The number of diagnosis codes and the fee schedule
     • Medical decision making or total time spent on the date of the encounter

     Correct answer: Medical decision making or total time spent on the date of the encounter

     Current CPT E/M office visit guidelines allow selecting the level based on medical decision making or total time spent on the date of the encounter. The patient's demographics, the place of service, payer, code count, and fee schedule do not set the E/M level under these guidelines.

118. Which set of elements defines the level of medical decision making in E/M coding?
     • Number and complexity of problems, amount and complexity of data, and risk of complications
     • Patient name, date of birth, and insurance ID
     • Place of service, modifier, and units
     • Deductible, copay, and coinsurance

     Correct answer: Number and complexity of problems, amount and complexity of data, and risk of complications

     Medical decision making is defined by the number and complexity of problems addressed, the amount and complexity of data reviewed, and the risk of complications or morbidity. Patient identifiers, claim fields, and cost-sharing amounts are not components of medical decision making.

119. In E/M coding, what is the key documentation difference between a new patient and an established patient?
     • A new patient is anyone seen in the current calendar year
     • A new patient has not received professional services from the provider or group within the past three years
     • An established patient must always be over age 65
     • A new patient is determined by the place of service code

     Correct answer: A new patient has not received professional services from the provider or group within the past three years

     A new patient is one who has not received professional services from the provider, or another provider of the same specialty in the same group, within the past three years. The distinction is not based on the calendar year, the patient's age, or the place of service code.

120. A physician spends 40 minutes of total time on the date of an established patient office visit, including reviewing records and counseling. Under current guidelines, this total time may be used to do what?
     • Determine the place of service code
     • Assign the diagnosis code
     • Select the appropriate E/M service level
     • Calculate the patient's deductible

     Correct answer: Select the appropriate E/M service level

     Total time on the date of the encounter may be used to select the appropriate E/M service level under current CPT guidelines. Total time does not determine the place of service code, assign the diagnosis, or calculate the deductible.

121. What do place of service (POS) codes identify on a claim?
     • The specific procedure performed
     • The patient's primary diagnosis
     • The provider's specialty
     • The setting in which a service was provided

     Correct answer: The setting in which a service was provided

     Place of service codes identify the setting in which a service was provided, such as an office or hospital. They do not identify the procedure, the diagnosis, or the provider's specialty, which are reported through other code sets and fields.

122. Which place of service code represents a physician's office?
     • 11
     • 21
     • 23
     • 31

     Correct answer: 11

     Place of service code 11 represents a physician's office. Code 21 is inpatient hospital, code 23 is the emergency room, and code 31 is a skilled nursing facility, so they do not designate the office setting.

123. A patient is treated as an inpatient in a hospital. Which place of service code is appropriate?
     • 11
     • 21
     • 12
     • 22

     Correct answer: 21

     Place of service code 21 designates inpatient hospital care. Code 11 is the office, code 12 is the patient's home, and code 22 is on-campus outpatient hospital, none of which represent inpatient hospital admission.

124. Why must the place of service code on a claim be accurate?
     • Because it changes the patient's diagnosis
     • Because it replaces the CPT code
     • Because it can affect how a service is processed and is required for correct claim reporting
     • Because it determines the patient's insurance premium

     Correct answer: Because it can affect how a service is processed and is required for correct claim reporting

     Accurate place of service reporting matters because it can affect how a service is processed and is required for correct claim reporting. It does not change the diagnosis, replace the procedure code, or determine the patient's premium.

125. A telehealth visit is conducted with the patient located in their home. Reporting the correct place of service code for this encounter is important because it does which of the following?
     • Selects the diagnosis code automatically
     • Bundles all procedures into one code
     • Eliminates the need for a CPT code
     • Identifies the setting so the service is reported accurately

     Correct answer: Identifies the setting so the service is reported accurately

     Reporting the correct place of service code identifies the setting so the service is reported accurately, which is essential for telehealth and other encounters. It does not select the diagnosis, bundle procedures, or remove the requirement for a CPT code.

126. What is the purpose of the National Correct Coding Initiative (NCCI)?
     • To promote correct coding and prevent improper payment from incorrect code combinations
     • To set the place of service codes
     • To establish patient eligibility
     • To create diagnosis codes

     Correct answer: To promote correct coding and prevent improper payment from incorrect code combinations

     The NCCI promotes correct coding methodologies and prevents improper payment that can result from incorrect code combinations. It does not set place of service codes, establish patient eligibility, or create diagnosis codes.

127. An NCCI procedure-to-procedure edit identifies which situation?
     • A patient whose insurance has lapsed
     • Two codes that should not be reported together for the same patient on the same day
     • A claim filed after the deadline
     • A missing provider signature

     Correct answer: Two codes that should not be reported together for the same patient on the same day

     An NCCI procedure-to-procedure edit identifies pairs of codes that should not be reported together for the same patient on the same date because one is considered a component of the other. It does not address lapsed coverage, filing deadlines, or missing signatures.

128. What does an NCCI medically unlikely edit (MUE) limit?
     • The number of patients a provider may treat
     • The number of diagnoses on a claim
     • The maximum units of a service a provider would typically report for one patient on one day
     • The patient's annual deductible

     Correct answer: The maximum units of a service a provider would typically report for one patient on one day

     A medically unlikely edit limits the maximum units of a service a provider would typically report for a single patient on a single date of service. It does not cap patient volume, the number of diagnoses, or the patient's deductible.

129. Two codes hit an NCCI edit, but documentation shows the services were truly distinct and separately performed. What is the correct coding response?
     • Delete one of the codes regardless of documentation
     • Change the diagnosis to bypass the edit
     • Report a higher-level code to avoid the edit
     • Append an appropriate NCCI-associated modifier, such as modifier 59, when supported by documentation

     Correct answer: Append an appropriate NCCI-associated modifier, such as modifier 59, when supported by documentation

     When documentation shows the services were truly distinct, the correct response is to append an appropriate NCCI-associated modifier, such as modifier 59, to indicate the distinct service. Deleting a code that was performed, altering the diagnosis, or upcoding are all improper ways to handle an edit.

130. An NCCI edit pair has a modifier indicator of 1. What does this indicate to the coder?
     • A modifier may be used to override the edit when clinical circumstances justify it
     • The edit can never be overridden by any modifier
     • The two codes are always reported together
     • The codes must be deleted from the claim

     Correct answer: A modifier may be used to override the edit when clinical circumstances justify it

     A modifier indicator of 1 means a modifier may be used to override the edit when clinical circumstances and documentation justify reporting the codes together. An indicator of 0 means no modifier can override the edit; an indicator of 1 does not require deletion or mandate joint reporting in all cases.

131. What is upcoding?
     • Reporting the most specific diagnosis available
     • Reporting a higher-level or more expensive code than the documentation supports
     • Submitting a claim before the deadline
     • Assigning the correct place of service code

     Correct answer: Reporting a higher-level or more expensive code than the documentation supports

     Upcoding is reporting a higher-level or more expensive code than the service actually performed or the documentation supports. Reporting the most specific supported diagnosis, meeting deadlines, and correct place of service reporting are proper practices, not upcoding.

132. A provider routinely bills a high-complexity office visit code for encounters that involve only a brief, straightforward problem. This pattern is best described as which of the following?
     • Unbundling
     • Down-coding
     • Upcoding
     • Bilateral reporting

     Correct answer: Upcoding

     Billing a high-complexity visit for encounters that only involve straightforward problems is upcoding because the reported level exceeds what the documentation supports. Unbundling involves splitting bundled codes, down-coding reports a lower level than supported, and bilateral reporting involves two-sided procedures.

133. Why is upcoding a coding-integrity concern?
     • It always reduces provider revenue
     • It is required by ICD-10-CM guidelines
     • It is the same as assigning the most specific code
     • It results in code assignment that does not match the documented service and can lead to improper payment

     Correct answer: It results in code assignment that does not match the documented service and can lead to improper payment

     Upcoding is a coding-integrity concern because the assigned code does not match the documented service and can lead to improper payment. It does not reduce revenue, is never required by coding guidelines, and is not the same as legitimately assigning the most specific supported code.

134. What is the best safeguard a coder can use to avoid upcoding?
     • Assign codes strictly according to the documentation in the medical record
     • Always assign the highest available code
     • Match the code to the highest fee on the schedule
     • Use unspecified codes for every encounter

     Correct answer: Assign codes strictly according to the documentation in the medical record

     Assigning codes strictly according to the documentation in the medical record is the best safeguard against upcoding because the code must reflect the documented service. Choosing the highest code, matching codes to fees, or defaulting to unspecified codes all detach coding from documentation.

135. What is unbundling in medical coding?
     • Reporting one combination code for related conditions
     • Reporting separate component codes for services that should be reported with a single comprehensive code
     • Selecting the most specific diagnosis
     • Verifying patient eligibility

     Correct answer: Reporting separate component codes for services that should be reported with a single comprehensive code

     Unbundling is reporting separate component codes for services that should be reported together under a single comprehensive code, often to increase reimbursement. Using a combination code, selecting specific diagnoses, and verifying eligibility are proper or unrelated activities.

136. A surgical procedure has a single comprehensive code that already includes the surgical approach. A coder reports the comprehensive procedure plus a separate code for the approach that is normally included. This is an example of which practice?
     • Upcoding
     • Bilateral coding
     • Unbundling
     • Correct combination coding

     Correct answer: Unbundling

     Separately reporting a component, such as the approach, that is already included in the comprehensive procedure code is unbundling. Upcoding involves reporting a higher-level single code, bilateral coding reports two-sided procedures, and correct combination coding would have used the single comprehensive code.

137. Which coding tool is most directly designed to detect and prevent unbundling?
     • The place of service code list
     • The fee schedule
     • The ICD-10-CM Alphabetic Index
     • National Correct Coding Initiative edits

     Correct answer: National Correct Coding Initiative edits

     National Correct Coding Initiative edits are most directly designed to detect and prevent unbundling by identifying component codes that should not be billed separately. The place of service list, the fee schedule, and the diagnosis index do not perform this code-pair bundling function.

138. Why is unbundling considered improper coding?
     • It can result in higher reimbursement than the appropriately reported single comprehensive code
     • It always lowers the provider's payment
     • It is required when two procedures are bilateral
     • It is the same as assigning a seventh character

     Correct answer: It can result in higher reimbursement than the appropriately reported single comprehensive code

     Unbundling is improper because billing separate component codes can yield higher reimbursement than the single comprehensive code that correctly represents the service. It does not lower payment, is not required for bilateral procedures, and is unrelated to seventh-character assignment.

139. A coder reviews a record that lists a definitive cancer diagnosis confirmed by pathology. Following ICD-10-CM guidelines, the coder should do which of the following?
     • Report only a symptom code
     • Report the confirmed malignancy code supported by the documentation
     • Report an uncertain-behavior code despite the confirmation
     • Omit the diagnosis because cancer is sensitive information

     Correct answer: Report the confirmed malignancy code supported by the documentation

     The coder should report the confirmed malignancy code supported by the documentation because a definitive, pathology-confirmed diagnosis warrants the specific code. Reporting only a symptom, using an uncertain-behavior code, or omitting the diagnosis would not reflect the confirmed condition.

140. When a patient presents for a procedure and the operative note documents a finding different from the pre-procedure diagnosis, which diagnosis should generally be coded?
     • The pre-procedure diagnosis only
     • Whichever diagnosis is more expensive
     • The postoperative diagnosis, as it is the most definitive
     • Neither diagnosis, only a Z code

     Correct answer: The postoperative diagnosis, as it is the most definitive

     The postoperative diagnosis should generally be coded because it represents the most definitive and confirmed information after the procedure. Coding only the pre-procedure diagnosis, choosing by cost, or defaulting to a Z code would not reflect the most accurate confirmed condition.

141. An NCCI edit pair has a modifier indicator of 0. A coder believes the two services were distinct. What is the correct action?
     • Append modifier 59 to force the edit to pay
     • Change the diagnosis code to bypass the edit
     • Report both codes without any review
     • Recognize that no modifier can override the edit, so the codes cannot be unbundled

     Correct answer: Recognize that no modifier can override the edit, so the codes cannot be unbundled

     With a modifier indicator of 0, no modifier can override the edit, so the codes cannot be reported separately regardless of the coder's belief. Forcing modifier 59, altering the diagnosis, or blindly reporting both codes would all be improper attempts to bypass a non-overridable edit.

142. A coder must select between modifier 25 and modifier 59 for a claim. Which statement correctly distinguishes their use?
     • Modifier 25 applies to a separately identifiable E/M service, while modifier 59 applies to a distinct procedural service
     • Both modifiers are used only on diagnosis codes
     • Modifier 25 reports bilateral procedures and modifier 59 reports the technical component
     • The two modifiers are interchangeable in all situations

     Correct answer: Modifier 25 applies to a separately identifiable E/M service, while modifier 59 applies to a distinct procedural service

     Modifier 25 applies to a significant, separately identifiable E/M service on the same day as a procedure, while modifier 59 identifies a distinct procedural service not normally reported together. They are not used on diagnosis codes, do not report bilateral or technical components, and are not interchangeable.

143. A claim reports an established office visit selected at a level that the documented medical decision making clearly does not support, in order to obtain a higher allowance. Beyond being incorrect, this E/M selection is an example of which coding-integrity violation?
     • Unbundling
     • Upcoding
     • Use of an Excludes1 note
     • Correct time-based coding

     Correct answer: Upcoding

     Selecting a higher E/M level than the documented medical decision making supports in order to gain a higher allowance is upcoding, a coding-integrity violation. It is not unbundling, has nothing to do with Excludes1 notes, and is the opposite of correct time-based or decision-based coding.

144. A coder cannot find a CPT or HCPCS Level II code that precisely describes a new service. Which approach aligns with correct coding principles?
     • Choose the closest higher-paying code regardless of fit
     • Report a diagnosis code in place of the procedure
     • Use an unlisted or not-otherwise-classified code with supporting documentation when no specific code exists
     • Leave the procedure off the claim entirely

     Correct answer: Use an unlisted or not-otherwise-classified code with supporting documentation when no specific code exists

     Using an unlisted or not-otherwise-classified code with supporting documentation is correct when no specific CPT or HCPCS code describes the service. Choosing a higher-paying mismatched code is improper, a diagnosis code cannot represent a procedure, and omitting a performed service misrepresents the encounter.

145. A coder selects an ICD-10-CM code at the three-character category level when a more specific code with additional characters is available and supported. What guideline does this violate?
     • The requirement to verify eligibility before coding
     • The place of service reporting rule
     • The timely filing requirement
     • The requirement to code to the highest level of specificity supported by the documentation

     Correct answer: The requirement to code to the highest level of specificity supported by the documentation

     Selecting a three-character category code when a more specific, supported code exists violates the requirement to code to the highest level of specificity supported by the documentation. Eligibility verification, place of service reporting, and timely filing are not coding-specificity guidelines.

146. Which claim form is the standard paper claim used by physicians and other non-institutional providers to bill for professional services?
     • CMS-1500
     • UB-04
     • CMS-1450
     • ABN form

     Correct answer: CMS-1500

     The CMS-1500 is the standard claim form for physicians and non-institutional (professional) providers. The UB-04, also called the CMS-1450, is the institutional claim form used by hospitals and facilities, and the ABN is a Medicare noncoverage notice, not a claim.

147. On the CMS-1500 claim form, in which block is the diagnosis code (ICD-10-CM) entered?
     • Block 11
     • Block 21
     • Block 24D
     • Block 33

     Correct answer: Block 21

     Block 21 of the CMS-1500 is where the ICD-10-CM diagnosis codes are reported. Block 24D holds procedure (CPT/HCPCS) codes, Block 33 holds the billing provider's information, and Block 11 holds the insured's policy or group number.

148. A billing specialist is completing a CMS-1500 form and must enter the CPT and HCPCS procedure codes for the services rendered. In which field are these procedure codes reported?
     • Block 17
     • Block 32
     • Block 24D
     • Block 21

     Correct answer: Block 24D

     Procedure codes (CPT/HCPCS) are reported in Block 24D of the CMS-1500. Block 21 is for diagnosis codes, Block 17 is for the referring provider, and Block 32 identifies the service facility location.

149. Which claim form is used by hospitals and other institutional providers to bill for facility services?
     • CMS-1500
     • CMS-R-131
     • Superbill
     • UB-04

     Correct answer: UB-04

     The UB-04 is the institutional claim form used by hospitals and facilities for facility charges. The CMS-1500 is the professional claim form, the CMS-R-131 is the Advance Beneficiary Notice, and a superbill is an internal charge document, not a payer claim form.

150. The UB-04 claim form is also known by which alternate name?
     • CMS-1450
     • CMS-1500
     • CMS-1490S
     • CMS-R-131

     Correct answer: CMS-1450

     The UB-04 institutional claim form is also designated the CMS-1450. The CMS-1500 is the professional claim form, the CMS-1490S is a patient request for Medicare payment, and the CMS-R-131 is the ABN.

151. A coding specialist must select the correct claim form for an outpatient hospital facility charge. Which form is appropriate?
     • ABN
     • UB-04
     • CMS-1500
     • CMS-1490S

     Correct answer: UB-04

     Outpatient hospital facility charges are billed on the UB-04 (CMS-1450) institutional claim form. The CMS-1500 reports the professional component, the CMS-1490S is a beneficiary payment request, and the ABN is a noncoverage notice.

152. What is the key difference between the CMS-1500 and the UB-04 claim forms?
     • The CMS-1500 reports diagnoses and the UB-04 reports procedures
     • The CMS-1500 is used only for Medicare and the UB-04 only for Medicaid
     • The CMS-1500 is for professional services and the UB-04 is for institutional/facility services
     • The CMS-1500 is electronic only and the UB-04 is paper only

     Correct answer: The CMS-1500 is for professional services and the UB-04 is for institutional/facility services

     The defining difference is provider type: the CMS-1500 bills professional/physician services while the UB-04 bills institutional/facility services. Both forms can be paper or have electronic equivalents, both report diagnoses and procedures, and both serve many payers.

153. What is a clean claim?
     • A claim that has been paid in full by the payer
     • A claim that has been appealed and overturned
     • A claim submitted only on paper rather than electronically
     • A claim submitted with all required information and no errors that can be processed without additional information

     Correct answer: A claim submitted with all required information and no errors that can be processed without additional information

     A clean claim is one that contains all required, accurate information and passes edits so the payer can adjudicate it without requesting additional information. It is defined by completeness at submission, not by whether it was paid, appealed, or its transmission method.

154. Why does submitting clean claims benefit a medical practice?
     • Clean claims are adjudicated faster, reducing the time to reimbursement
     • Clean claims allow the practice to charge a higher fee
     • Clean claims exempt the patient from any cost-sharing
     • Clean claims eliminate the need to verify insurance

     Correct answer: Clean claims are adjudicated faster, reducing the time to reimbursement

     The main advantage of a clean claim is faster adjudication and quicker payment because the payer needs no additional information. Clean claims do not change the fee, the patient's cost-sharing, or the need for prior insurance verification.

155. A claim is returned to the practice unprocessed because the patient's insurance member ID was entered incorrectly. This claim would best be described as which of the following?
     • An appealed claim
     • Not a clean claim
     • A clean claim
     • A paid claim

     Correct answer: Not a clean claim

     Because the claim contained an error (wrong member ID) and could not be processed, it is not a clean claim. A clean claim has complete, accurate information allowing the payer to adjudicate it without returning it for correction.

156. What is the primary function of a clearinghouse in the medical billing process?
     • To determine whether a service is medically necessary
     • To collect patient copayments at the point of service
     • To receive, scrub, and forward claims in the correct format to the appropriate payers
     • To set the fee schedule that payers must follow

     Correct answer: To receive, scrub, and forward claims in the correct format to the appropriate payers

     A clearinghouse is an intermediary that receives claims from providers, scrubs them for errors, reformats them to each payer's requirements, and forwards them to the correct payer. It does not set fee schedules, judge medical necessity, or collect patient payments.

157. When a clearinghouse scrubs a claim, what is it doing?
     • Removing protected health information from the claim
     • Negotiating the allowed amount with the payer
     • Posting the payment to the patient's account
     • Checking the claim for errors and missing data before sending it to the payer

     Correct answer: Checking the claim for errors and missing data before sending it to the payer

     Scrubbing means the clearinghouse reviews the claim for errors, formatting issues, and missing required data so problems are caught before the payer receives it. It does not strip PHI, negotiate allowed amounts, or post payments.

158. A practice submits electronic claims to many different insurance companies. How does using a clearinghouse simplify this process?
     • It lets the practice send claims to one place that routes them to the correct payers in each payer's required format
     • It guarantees that every claim will be paid in full
     • It removes the need for the practice to assign diagnosis codes
     • It allows the practice to bypass timely filing deadlines

     Correct answer: It lets the practice send claims to one place that routes them to the correct payers in each payer's required format

     A clearinghouse acts as a single submission point that formats and routes claims to many payers, so the practice does not have to manage each payer's connection directly. It does not guarantee payment, replace coding, or waive filing deadlines.

159. What is the difference between a rejected claim and a denied claim?
     • There is no difference; the terms mean the same thing
     • A rejected claim never entered the payer's adjudication system due to errors, while a denied claim was processed but payment was refused
     • A rejected claim was processed and paid, while a denied claim was never received
     • A rejected claim can never be corrected, while a denied claim can always be corrected

     Correct answer: A rejected claim never entered the payer's adjudication system due to errors, while a denied claim was processed but payment was refused

     A rejected claim contains errors that prevent it from being accepted into adjudication, so it is returned for correction; a denied claim was accepted and adjudicated, but the payer decided not to pay it. The terms are not interchangeable.

160. A claim is returned by the clearinghouse before reaching the payer because a required field was left blank. This is best classified as which of the following?
     • A clean claim
     • An appeal
     • A claim rejection
     • A claim denial

     Correct answer: A claim rejection

     A claim stopped at the clearinghouse or payer front-end for a formatting or completeness error, before adjudication, is a rejection. A denial occurs only after a claim has been adjudicated, a clean claim has no such error, and an appeal is a later dispute step.

161. Which action is generally the fastest way to address a rejected claim?
     • File a formal written appeal with supporting documentation
     • Write off the balance as uncollectible
     • Bill the entire amount to the patient immediately
     • Correct the error and resubmit the claim

     Correct answer: Correct the error and resubmit the claim

     Because a rejected claim never entered adjudication, the proper response is to fix the identified error and resubmit it. A formal appeal applies to denied claims, and writing off or billing the patient skips the needed correction.

162. A payer adjudicates a claim and refuses payment because the service is not a covered benefit under the patient's plan. This outcome is best described as which of the following?
     • A claim denial
     • A claim rejection
     • A clean claim
     • A crossover claim

     Correct answer: A claim denial

     When a payer processes (adjudicates) a claim and decides not to pay it, the result is a denial. A rejection occurs before adjudication, a clean claim is error-free at submission, and a crossover claim is one automatically forwarded to a secondary payer.

163. Which of the following is a common reason a claim is denied?
     • The provider obtained prior authorization in advance
     • The service was not medically necessary based on the reported diagnosis
     • The claim was scrubbed by a clearinghouse before submission
     • The patient paid the copayment at the visit

     Correct answer: The service was not medically necessary based on the reported diagnosis

     Lack of demonstrated medical necessity, where the diagnosis does not support the procedure, is a frequent denial reason. Scrubbing, paying a copay, and obtaining prior authorization are all steps that help claims process correctly rather than causing denials.

164. What is denial management in a medical billing office?
     • The process of setting the practice's fee schedule
     • The process of converting paper claims to electronic format
     • The process of reviewing, correcting, and resolving denied claims to recover reimbursement
     • The process of preventing patients from seeing specialists

     Correct answer: The process of reviewing, correcting, and resolving denied claims to recover reimbursement

     Denial management is the systematic work of analyzing denied claims, identifying the cause, correcting issues, and pursuing appeals to recover owed reimbursement. It is unrelated to referral control, fee scheduling, or claim formatting.

165. After a claim is denied, a billing specialist determines the denial was incorrect because the service was in fact covered. What is the appropriate next step?
     • Immediately write the balance off as a courtesy adjustment
     • Bill the full charge to the patient
     • Delete the claim and take no further action
     • File an appeal with the payer including supporting documentation

     Correct answer: File an appeal with the payer including supporting documentation

     When a denial appears incorrect and the service was covered, the specialist should appeal, submitting documentation that supports payment. Writing off, balance-billing the patient, or abandoning the claim would forfeit legitimate reimbursement.

166. What is the purpose of the claims appeal process?
     • To request that a payer reconsider and reverse a denied or underpaid claim
     • To submit a claim for the first time to the payer
     • To verify a patient's insurance eligibility
     • To assign diagnosis and procedure codes to an encounter

     Correct answer: To request that a payer reconsider and reverse a denied or underpaid claim

     An appeal formally asks the payer to reconsider a denial or underpayment and overturn its decision. It is not the initial claim submission, eligibility verification, or the coding step.

167. When filing a first-level appeal of a denied claim, which of the following is most important to include?
     • A request to waive the patient's coinsurance
     • Documentation that supports the medical necessity and accuracy of the service billed
     • A new fee schedule for the payer to adopt
     • The patient's signed assignment of benefits only

     Correct answer: Documentation that supports the medical necessity and accuracy of the service billed

     A strong appeal includes supporting documentation, such as records demonstrating medical necessity and the accuracy of the codes billed, to justify reversing the denial. A fee schedule, an assignment of benefits alone, or a coinsurance waiver request would not address the denial reason.

168. What is a remittance advice (RA)?
     • A form authorizing the release of medical records
     • A document setting the patient's annual deductible
     • A document from the payer explaining how a submitted claim was adjudicated, including payments and adjustments
     • A notice the provider sends to the patient requesting payment

     Correct answer: A document from the payer explaining how a submitted claim was adjudicated, including payments and adjustments

     A remittance advice is sent by the payer to the provider and details how each claim line was adjudicated, including amounts paid, adjustments, and reasons. It is not a patient statement, a records-release form, or a deductible notice.

169. A billing specialist receives a remittance advice from a payer. What is the most appropriate use of this document?
     • To verify the patient's eligibility for next year
     • To assign CPT codes to the encounter
     • To obtain prior authorization for a future service
     • To post payments and adjustments to patient accounts and identify any denials

     Correct answer: To post payments and adjustments to patient accounts and identify any denials

     The RA is used to post the payer's payments and contractual adjustments to accounts and to spot any denied lines that need follow-up. It is not used for eligibility verification, coding, or prior authorization.

170. On a remittance advice, what does an adjustment reason code communicate?
     • The reason the payer reduced, adjusted, or denied payment on a claim line
     • The patient's home address
     • The provider's tax identification number
     • The date the patient's coverage began

     Correct answer: The reason the payer reduced, adjusted, or denied payment on a claim line

     Adjustment reason codes on an RA explain why a payment was reduced, adjusted, or denied for a specific claim line, guiding follow-up. They do not convey patient addresses, provider tax IDs, or coverage start dates.

171. What is an electronic remittance advice (ERA)?
     • An electronic eligibility verification request
     • The electronic, standardized version of a remittance advice transmitted in the HIPAA 835 transaction
     • An electronic claim sent from the provider to the payer
     • An electronic referral to a specialist

     Correct answer: The electronic, standardized version of a remittance advice transmitted in the HIPAA 835 transaction

     An ERA is the electronic form of a remittance advice, exchanged using the standardized HIPAA 835 transaction. It is not the outbound claim, a referral, or an eligibility request.

172. Which standardized HIPAA transaction is used to transmit an electronic remittance advice?
     • 270
     • 271
     • 835
     • 837

     Correct answer: 835

     The 835 transaction carries the electronic remittance advice (health care claim payment/advice). The 837 is the electronic claim, the 270 is an eligibility inquiry, and the 271 is the eligibility response.

173. A practice wants to speed payment posting by automatically importing payer adjudication results into its billing software. Which document supports this electronic auto-posting?
     • The patient statement
     • The Advance Beneficiary Notice
     • The superbill
     • The electronic remittance advice (ERA)

     Correct answer: The electronic remittance advice (ERA)

     The ERA delivers adjudication results in a standardized electronic format that billing software can read to auto-post payments and adjustments. A patient statement, ABN, and superbill are not payer adjudication transactions.

174. What is an explanation of benefits (EOB)?
     • A document the payer sends to the patient explaining how a claim was processed and what the patient may owe
     • A claim form submitted to the payer for reimbursement
     • A document setting the provider's contracted fee schedule
     • A form used to obtain prior authorization

     Correct answer: A document the payer sends to the patient explaining how a claim was processed and what the patient may owe

     An EOB is sent by the payer to the patient (the insured) describing how the claim was processed, what was paid, and the patient's potential responsibility. It is not a claim, a fee schedule, or a prior authorization form.

175. What is the main difference between an explanation of benefits (EOB) and a remittance advice (RA)?
     • An EOB lists procedure codes and an RA lists only diagnosis codes
     • An EOB goes to the patient and an RA goes to the provider
     • An EOB goes to the provider and an RA goes to the patient
     • An EOB is electronic and an RA is always paper

     Correct answer: An EOB goes to the patient and an RA goes to the provider

     Both documents explain claim adjudication, but the EOB is directed to the patient/insured while the RA is directed to the provider. Either can be paper or electronic, and both reference how charges were processed rather than splitting code types.

176. A patient calls the billing office confused about a document from their insurer showing the amount they may owe after the claim was processed. Which document is the patient most likely describing?
     • A CMS-1500 claim form
     • An assignment of benefits
     • An explanation of benefits (EOB)
     • A remittance advice (RA)

     Correct answer: An explanation of benefits (EOB)

     A document sent by the insurer to the patient showing claim processing and the patient's potential responsibility is an explanation of benefits. The RA goes to the provider, the CMS-1500 is a claim form, and the assignment of benefits is an authorization.

177. What is the purpose of an accounts receivable (A/R) aging report?
     • To list the practice's fixed monthly expenses
     • To verify each patient's insurance eligibility
     • To record the diagnosis codes used for each encounter
     • To group outstanding balances by how long they have been unpaid so staff can prioritize follow-up

     Correct answer: To group outstanding balances by how long they have been unpaid so staff can prioritize follow-up

     An A/R aging report categorizes unpaid balances by age (for example 0-30, 31-60, 61-90 days) so the office can target older, higher-risk receivables for follow-up. It does not track expenses, verify eligibility, or record codes.

178. On an A/R aging report, an account is listed in the 91-120 day column. What does this indicate?
     • The balance has been outstanding for 91 to 120 days and is overdue for follow-up
     • The patient has 91 to 120 days of remaining coverage
     • The claim must be filed within 91 to 120 days
     • The provider will be paid in 91 to 120 days

     Correct answer: The balance has been outstanding for 91 to 120 days and is overdue for follow-up

     The aging columns reflect how long a balance has been unpaid, so a 91-120 day entry means the balance has gone unpaid that long and needs prompt collection action. It is not a measure of coverage, filing deadlines, or guaranteed payment timing.

179. Why should a billing specialist prioritize accounts in the older columns of an A/R aging report?
     • Older balances are exempt from timely filing rules
     • Older balances are at greater risk of becoming uncollectible the longer they remain unpaid
     • Older balances always have the smallest dollar amounts
     • Older balances are automatically paid by the clearinghouse

     Correct answer: Older balances are at greater risk of becoming uncollectible the longer they remain unpaid

     The longer a balance ages, the harder it becomes to collect, so older receivables are prioritized to maximize recovery. Age does not determine dollar size, clearinghouses do not pay claims, and aging does not exempt timely filing.

180. What does the Resource-Based Relative Value Scale (RBRVS) determine?
     • Which diagnosis codes are valid for an encounter
     • The timely filing deadline for a claim
     • The relative value, and therefore the payment, for physician services under Medicare
     • The patient's annual deductible amount

     Correct answer: The relative value, and therefore the payment, for physician services under Medicare

     RBRVS assigns relative value units to physician services and is the basis Medicare uses to calculate payment for those services. It does not set deductibles, validate diagnosis codes, or define filing deadlines.

181. Under the RBRVS methodology, payment is calculated using relative value units (RVUs) multiplied by which factor?
     • The patient's deductible
     • The number of diagnosis codes on the claim
     • The provider's NPI
     • A conversion factor (a dollar amount)

     Correct answer: A conversion factor (a dollar amount)

     RBRVS payment is determined by multiplying the service's total RVUs (adjusted geographically) by a dollar conversion factor. The deductible, diagnosis count, and NPI are not multipliers in the RBRVS payment formula.

182. The RBRVS reimbursement methodology is most commonly associated with payment for which type of services?
     • Physician and other professional services
     • Inpatient hospital stays
     • Skilled nursing facility room and board
     • Outpatient prescription drugs at a pharmacy

     Correct answer: Physician and other professional services

     RBRVS underlies the Medicare Physician Fee Schedule and is used to pay physician and other professional services. Inpatient stays use DRG-based payment, and SNF and pharmacy reimbursement use other prospective systems.

183. What is a diagnosis-related group (DRG) used for?
     • Assigning modifiers to CPT codes
     • Classifying inpatient hospital cases into groups for prospective payment
     • Reporting physician office visit levels
     • Verifying a patient's insurance eligibility

     Correct answer: Classifying inpatient hospital cases into groups for prospective payment

     DRGs group inpatient hospital cases with similar clinical characteristics and resource use to set a fixed prospective payment per admission. They are not for office visit leveling, eligibility checks, or modifier assignment.

184. Under a diagnosis-related group (DRG) prospective payment system, how is the hospital generally reimbursed for an inpatient admission?
     • An amount based on the patient's deductible only
     • A per-day amount that increases with each additional day
     • A predetermined fixed amount based on the assigned DRG regardless of the exact length of stay
     • An amount equal to the hospital's billed charges

     Correct answer: A predetermined fixed amount based on the assigned DRG regardless of the exact length of stay

     Under DRG prospective payment, the hospital receives a fixed, predetermined amount tied to the assigned DRG, not billed charges or a simple per-day rate. This creates an incentive to manage resources efficiently.

185. DRG-based reimbursement is primarily used for which setting?
     • Physician office visits
     • Retail pharmacy drug claims
     • Independent laboratory tests
     • Inpatient acute care hospital admissions

     Correct answer: Inpatient acute care hospital admissions

     DRGs were developed for and are used to pay inpatient acute care hospital admissions. Office visits, pharmacy claims, and lab tests are reimbursed under different methodologies.

186. What is a fee schedule in medical billing?
     • A list of the maximum allowed amounts a payer will reimburse for specific services
     • A calendar of when patients are scheduled for appointments
     • A list of diagnosis codes approved for a payer
     • A schedule of when claims must be appealed

     Correct answer: A list of the maximum allowed amounts a payer will reimburse for specific services

     A fee schedule is the payer's list of allowed (maximum) reimbursement amounts for covered services by code. It is not an appointment calendar, an approved diagnosis list, or an appeal timeline.

187. A provider's charge for a service is $250, but the payer's fee schedule allows $180 and the provider is participating. What is the most likely outcome for the $70 difference?
     • It is paid by a secondary payer automatically
     • It is a contractual adjustment that must be written off and cannot be billed to the patient
     • It must be billed to the patient as a balance
     • It is added to the patient's deductible

     Correct answer: It is a contractual adjustment that must be written off and cannot be billed to the patient

     For a participating provider, the difference between the charge and the contracted allowed amount is a contractual adjustment that is written off and cannot be balance-billed to the patient. It is not added to the deductible or automatically paid by a secondary plan.

188. The allowed amount on a fee schedule represents which of the following?
     • The provider's full billed charge
     • The premium the patient pays each month
     • The maximum amount the payer considers payable for a covered service
     • The amount the patient must pay before insurance begins

     Correct answer: The maximum amount the payer considers payable for a covered service

     The allowed amount is the maximum the payer recognizes as payable for a covered service, which then determines the split between plan payment and patient cost-sharing. It is not the deductible, the billed charge, or the premium.

189. What is a write-off in medical billing?
     • The amount the patient pays at the time of service
     • The premium charged by the insurance plan
     • The diagnosis code entered on the claim
     • An amount the practice removes from a patient account because it will not be collected

     Correct answer: An amount the practice removes from a patient account because it will not be collected

     A write-off is an adjustment that removes an uncollectible or contractually disallowed amount from the patient's account balance. It is not a point-of-service payment, a premium, or a diagnosis code.

190. A participating provider posts the payer's payment and reduces the patient's balance by the contracted disallowed amount. This reduction is best described as which type of write-off?
     • A contractual write-off (adjustment)
     • A bad-debt write-off
     • A charity-care write-off
     • A timely filing write-off

     Correct answer: A contractual write-off (adjustment)

     Removing the difference between the charge and the contracted allowed amount is a contractual write-off (adjustment) required by the provider's payer agreement. Bad-debt, charity-care, and timely-filing write-offs arise from different causes.

191. A claim was denied solely because it was submitted after the payer's filing deadline, and the deadline lapse was the practice's fault. The unpaid amount typically becomes which of the following?
     • An amount paid by the secondary payer
     • A write-off the practice absorbs because it cannot be billed to the patient
     • A balance billed to the patient
     • An amount added to the patient's coinsurance

     Correct answer: A write-off the practice absorbs because it cannot be billed to the patient

     When a claim is denied because of the practice's own untimely filing, the amount cannot be billed to the patient and is written off by the practice. It is not converted to patient coinsurance or shifted to a secondary payer.

192. What is a patient statement?
     • A document explaining the payer's fee schedule
     • A request for prior authorization
     • A bill sent to the patient showing the balance they owe after insurance has processed the claim
     • A claim sent to the insurance company

     Correct answer: A bill sent to the patient showing the balance they owe after insurance has processed the claim

     A patient statement is the bill the practice sends to the patient showing the remaining balance after the payer has adjudicated the claim. It is not a payer claim, a fee-schedule explanation, or an authorization request.

193. When is it generally appropriate to send a patient statement?
     • Before verifying the patient's insurance
     • Immediately when the claim is first submitted to the payer
     • Only after the claim has been denied entirely
     • After the insurance has processed the claim and a patient-responsibility balance remains

     Correct answer: After the insurance has processed the claim and a patient-responsibility balance remains

     A patient statement is sent once the payer has adjudicated the claim and a patient-responsibility amount (such as deductible, copay, or coinsurance) remains. Sending it before adjudication or eligibility checks risks billing the patient an inaccurate amount.

194. A patient statement should clearly show which of the following to the patient?
     • The amount the patient owes after insurance payments and adjustments
     • The provider's internal cost of the supplies used
     • The payer's full proprietary fee schedule
     • The other patients seen on the same day

     Correct answer: The amount the patient owes after insurance payments and adjustments

     An effective patient statement clearly presents the patient's remaining responsibility after insurance payments and adjustments are applied. It should not disclose internal costs, proprietary payer fee schedules, or other patients' information.

195. What is a crossover claim?
     • A claim sent to a clearinghouse for scrubbing
     • A claim automatically forwarded from the primary payer to the secondary payer after primary adjudication
     • A claim submitted twice to the same payer in error
     • A claim that crosses from paper to electronic format

     Correct answer: A claim automatically forwarded from the primary payer to the secondary payer after primary adjudication

     A crossover claim is automatically sent from the primary payer to the secondary payer once the primary has processed it, commonly seen with Medicare crossing to Medicaid or supplemental plans. It is not a duplicate, a format change, or a scrubbing step.

196. A Medicare beneficiary also has Medicaid coverage. After Medicare processes the claim, it is automatically sent to Medicaid for secondary consideration. What is this arrangement called?
     • A rejected claim
     • An appeal
     • A crossover claim
     • A clean claim

     Correct answer: A crossover claim

     When Medicare automatically forwards the adjudicated claim to Medicaid as the secondary payer, it is a crossover claim. It is not described as a clean claim, a rejection, or an appeal.

197. What is the main benefit of a crossover claim arrangement for a billing office?
     • The patient owes nothing regardless of coverage
     • The primary payer pays the entire allowed amount
     • The claim bypasses timely filing rules
     • The secondary claim is forwarded automatically, eliminating a separate manual submission

     Correct answer: The secondary claim is forwarded automatically, eliminating a separate manual submission

     The crossover process automatically forwards the claim to the secondary payer, sparing the office from preparing and submitting a separate secondary claim. It does not eliminate patient responsibility, guarantee full primary payment, or waive filing rules.

198. What is a timely filing limit?
     • The maximum amount of time after the date of service in which a claim must be submitted to the payer
     • The time a patient has to pay their statement
     • The time a payer has to issue payment after receiving a claim
     • The time a provider has to obtain prior authorization

     Correct answer: The maximum amount of time after the date of service in which a claim must be submitted to the payer

     A timely filing limit is the deadline, measured from the date of service, by which a claim must be submitted to be considered for payment. It is not the patient payment window, the payer's payment deadline, or an authorization timeframe.

199. A claim is denied with the reason that it was received after the payer's filing deadline. Which billing rule was violated?
     • The NCCI edit rule
     • The timely filing limit
     • The coordination of benefits rule
     • The assignment of benefits rule

     Correct answer: The timely filing limit

     A denial for being received after the submission deadline reflects a timely filing limit violation. Coordination of benefits, assignment of benefits, and NCCI edits address payer order, payment direction, and code pairings, not filing deadlines.

200. What is the most effective way for a billing office to avoid timely filing denials?
     • Submit claims only after the patient pays in full
     • Bill the patient before submitting to the payer
     • Submit clean claims promptly and track each payer's filing deadlines
     • Wait until the end of the year to submit all claims at once

     Correct answer: Submit clean claims promptly and track each payer's filing deadlines

     Prompt submission of clean claims, combined with tracking each payer's specific deadlines, prevents timely filing denials. Batching claims to year-end, waiting for patient payment, or pre-billing the patient all increase the risk of missing deadlines.

201. On the CMS-1500 form, which block is used to enter the billing provider's information and NPI?
     • Block 21
     • Block 24D
     • Block 1
     • Block 33

     Correct answer: Block 33

     Block 33 of the CMS-1500 captures the billing provider's name, address, and NPI. Block 21 holds diagnosis codes, Block 24D holds procedure codes, and Block 1 indicates the type of insurance.

202. A claim line on a remittance advice shows the billed charge, the allowed amount, the contractual adjustment, the plan payment, and the patient responsibility. Which figure should be written off rather than billed to the patient by a participating provider?
     • The contractual adjustment
     • The patient responsibility
     • The plan payment
     • The billed charge

     Correct answer: The contractual adjustment

     The contractual adjustment is the disallowed difference between the charge and the allowed amount, which a participating provider writes off. The patient responsibility is billed to the patient, the plan payment is what the payer paid, and the billed charge is the original amount.

203. A claim is denied because the diagnosis code does not support medical necessity for the procedure, but the record clearly documents a supporting condition that was miscoded. What is the most appropriate corrective action?
     • Resubmit the claim unchanged
     • Correct the diagnosis code and resubmit or appeal with documentation
     • Write off the entire balance immediately
     • Transfer the full balance to the patient

     Correct answer: Correct the diagnosis code and resubmit or appeal with documentation

     When a documented condition was miscoded, the fix is to correct the diagnosis code and resubmit or appeal with supporting documentation to obtain payment. Writing off, balance-billing the patient, or resubmitting the same error would not resolve the denial.

204. Which sequence correctly reflects the back-end claims workflow after a service is provided?
     • Receive the remittance advice, submit the claim, code the encounter, post payment
     • Submit the claim, code the encounter, receive the remittance advice, post payment
     • Code the encounter, submit the claim, receive the remittance advice, post payment, follow up on denials
     • Post payment, code the encounter, submit the claim, follow up on denials

     Correct answer: Code the encounter, submit the claim, receive the remittance advice, post payment, follow up on denials

     The back-end flow is to code the encounter, submit the claim, receive the remittance advice, post the payment and adjustments, then follow up on any denials. The other sequences place posting or remittance before submission, which is not possible.

205. A patient has primary and secondary insurance. After the primary remittance advice is posted and a balance remains, what should the billing specialist do before sending the patient a statement?
     • Write off the remaining balance
     • Send the statement to the patient immediately
     • Resubmit the claim to the primary payer
     • Submit the claim to the secondary payer

     Correct answer: Submit the claim to the secondary payer

     When secondary coverage exists, the remaining balance after primary adjudication should be submitted to the secondary payer before billing the patient. Writing off, billing the patient immediately, or resubmitting to the primary would be premature or incorrect.

206. A practice's A/R aging report shows a rising percentage of receivables in the over-120-day column. What does this trend most likely indicate?
     • A problem in claims follow-up or collections that needs corrective action
     • That patient volume has increased
     • That the fee schedule is too low
     • That the practice is submitting too many clean claims

     Correct answer: A problem in claims follow-up or collections that needs corrective action

     A growing share of receivables in the oldest column signals breakdowns in follow-up or collections that require attention to recover revenue. It is not explained by patient volume, the fee schedule level, or submitting clean claims.

207. A billing specialist must decide which claim form to use for a physician's professional charges and which for the hospital's facility charges for the same inpatient stay. Which selection is correct?
     • UB-04 for both
     • CMS-1500 for the physician's professional charges and UB-04 for the hospital's facility charges
     • UB-04 for the physician and CMS-1500 for the hospital
     • CMS-1500 for both

     Correct answer: CMS-1500 for the physician's professional charges and UB-04 for the hospital's facility charges

     Professional charges go on the CMS-1500 and institutional/facility charges go on the UB-04, so the physician's component uses the CMS-1500 and the hospital's component uses the UB-04. Using one form for both, or swapping them, would be incorrect.

208. A claim is electronically transmitted, accepted into adjudication, and the payer applies the allowed amount, pays its portion, and assigns the remainder to the patient's coinsurance. Which document reports these details to the provider?
     • The Advance Beneficiary Notice
     • The superbill
     • The remittance advice
     • The explanation of benefits

     Correct answer: The remittance advice

     The remittance advice reports adjudication details, including the allowed amount, payment, and coinsurance, to the provider. The EOB conveys this to the patient, the ABN is a noncoverage notice, and the superbill is an internal charge document.

209. A clearinghouse returns a batch report showing several claims were not forwarded to payers because of invalid code formats. What is the correct interpretation of these claims' status?
     • They are denials that require a formal appeal
     • They were paid and posted
     • They were written off as uncollectible
     • They are rejections that must be corrected and resubmitted before adjudication

     Correct answer: They are rejections that must be corrected and resubmitted before adjudication

     Claims stopped at the clearinghouse for format errors before reaching the payer are rejections; they must be corrected and resubmitted. They are not denials (which require adjudication first), and they were neither paid nor written off.

210. A payer's fee schedule allows $120 for a service. The patient has met the deductible and owes 20% coinsurance. The provider participates. How much will the participating provider expect to collect from the patient?
     • $24
     • $96
     • $120
     • $144

     Correct answer: $24

     With a $120 allowed amount and 20% coinsurance, the patient owes $24 (20% of $120). The remaining $96 is the plan's payment; $120 is the full allowed amount and $144 is not relevant to the allowed-amount calculation.

211. Why might a billing office choose to receive electronic remittance advices (ERAs) instead of paper remittance advices?
     • ERAs extend the timely filing deadline
     • ERAs can be imported to auto-post payments, improving speed and accuracy
     • ERAs increase the allowed amount on each claim
     • ERAs remove the patient's responsibility for coinsurance

     Correct answer: ERAs can be imported to auto-post payments, improving speed and accuracy

     ERAs deliver adjudication data electronically so software can auto-post payments and adjustments, speeding posting and reducing manual errors. They do not change allowed amounts, patient coinsurance, or filing deadlines.

212. A patient receives an explanation of benefits showing the service was applied to their deductible, so the plan paid nothing. What does the patient's responsibility on the resulting statement represent?
     • The provider's billed charge minus the premium
     • The secondary payer's portion
     • The deductible amount applied to the service
     • A contractual write-off

     Correct answer: The deductible amount applied to the service

     When the plan applies the allowed amount to the deductible and pays nothing, the patient responsibility on the statement is the deductible amount applied to that service. It is not a write-off, a premium calculation, or a secondary-payer share.

213. A claim was denied as a duplicate, but the billing specialist confirms the original was never paid and the service was provided once. What is the appropriate next step?
     • Write off the balance as a duplicate
     • Bill the patient for the full charge
     • Submit a third identical claim
     • Appeal the denial with documentation showing the service was performed and not previously paid

     Correct answer: Appeal the denial with documentation showing the service was performed and not previously paid

     When a duplicate denial is incorrect, the specialist should appeal with documentation proving the service occurred once and was not paid. Writing off, billing the patient, or resubmitting an identical claim would not resolve the erroneous denial.

214. Under a DRG payment system, a hospital admits a patient whose actual costs exceed the fixed DRG payment. What is the financial implication for the hospital?
     • The hospital generally absorbs the excess cost because payment is fixed by the DRG
     • The hospital bills the patient for the excess automatically
     • The payer increases the DRG payment to match costs
     • The hospital may bill a secondary DRG for the difference

     Correct answer: The hospital generally absorbs the excess cost because payment is fixed by the DRG

     Because DRG payment is a fixed prospective amount, costs above that amount are generally absorbed by the hospital, creating an incentive for efficiency. The excess is not automatically billed to the patient, matched by the payer, or recovered with a second DRG.

215. A patient account has been outstanding for over a year, all collection efforts have failed, and the amount is deemed uncollectible. How is this amount most accurately categorized?
     • A crossover claim
     • A bad-debt write-off
     • A contractual adjustment
     • A timely filing rejection

     Correct answer: A bad-debt write-off

     An uncollectible patient balance removed after failed collection efforts is a bad-debt write-off. A contractual adjustment stems from a payer agreement, a timely filing rejection is a deadline issue, and a crossover claim is a secondary-forwarding mechanism.

216. Why is it important for a patient statement to be sent only after the remittance advice has been posted?
     • So the claim can bypass the clearinghouse
     • So the timely filing limit is extended
     • So the statement reflects the accurate patient-responsibility balance after insurance adjustments
     • So the patient pays before the payer

     Correct answer: So the statement reflects the accurate patient-responsibility balance after insurance adjustments

     Posting the remittance advice first ensures the statement shows the correct patient responsibility after the payer's payment and adjustments. It is not meant to make the patient pay before the payer, bypass the clearinghouse, or extend filing deadlines.

217. A Medicare claim for a patient with a Medicare supplemental (Medigap) plan is automatically forwarded to the supplemental plan after Medicare pays. This automatic forwarding is an example of which process?
     • A claim rejection
     • A contractual write-off
     • Insurance verification
     • A crossover claim

     Correct answer: A crossover claim

     Automatic forwarding of a Medicare-adjudicated claim to a supplemental (Medigap) plan is a crossover claim. It is not a rejection, a write-off, or eligibility verification.

218. A billing specialist notices a payer consistently allows less than the practice's billed charges, producing routine contractual adjustments on the remittance advice. What does this pattern reflect?
     • The provider's contracted fee schedule with that payer sets allowed amounts below the billed charges
     • The patient is overpaying their coinsurance
     • The claims are being rejected by the clearinghouse
     • The timely filing limit is too short

     Correct answer: The provider's contracted fee schedule with that payer sets allowed amounts below the billed charges

     Routine contractual adjustments occur because the contracted fee schedule sets allowed amounts below the billed charges, and the difference is written off. This is unrelated to patient coinsurance accuracy, clearinghouse rejections, or filing deadlines.

219. A claim was submitted electronically and accepted by the payer, then the payer issued payment for part of the line items and denied one line as not covered. Which document communicates this mixed result to the provider?
     • The assignment of benefits
     • The remittance advice
     • The patient statement
     • The Advance Beneficiary Notice

     Correct answer: The remittance advice

     A remittance advice reports line-by-line adjudication to the provider, including paid lines and the denied, noncovered line. A patient statement bills the patient, the ABN is a noncoverage notice, and the assignment of benefits is an authorization.

220. A claim is rejected at the payer's front-end edits because the patient's date of birth does not match payer records. What is the correct response?
     • Write off the charge
     • Bill the patient for the full amount
     • Verify and correct the date of birth, then resubmit the claim
     • File a formal appeal with medical records

     Correct answer: Verify and correct the date of birth, then resubmit the claim

     A front-end rejection for mismatched demographics is resolved by verifying and correcting the data, then resubmitting. A formal appeal applies to adjudicated denials, and writing off or billing the patient skips the necessary correction.

221. Why is the billing provider's NPI in Block 33 of the CMS-1500 important to reimbursement?
     • It sets the allowed amount for the service
     • It determines the patient's coinsurance percentage
     • It establishes the timely filing deadline
     • It identifies the entity to be paid, and an incorrect or missing NPI can cause the claim to be rejected or denied

     Correct answer: It identifies the entity to be paid, and an incorrect or missing NPI can cause the claim to be rejected or denied

     The billing provider NPI in Block 33 identifies the payee; if it is missing or wrong, the claim can be rejected or denied. The NPI does not set allowed amounts, coinsurance percentages, or filing deadlines.
