- Code the acute condition first, then the chronic (Correct answer)
- Code the chronic condition only
- Code the acute condition only
- Code the chronic condition first, then the acute
Correct answer: Code the acute condition first, then the chronic
When both acute and chronic forms of a condition exist and both subentries exist in the index, sequence the acute code first.
Question 52: What is the key difference between a claim 'rejection' and a claim 'denial'?
- Denials can never be appealed; rejections can always be corrected
- Rejections result in payment at a reduced rate; denials result in zero payment
- A rejection occurs before adjudication due to technical errors; a denial occurs after adjudication on clinical or coverage grounds (Correct answer)
- Rejections are for Medicare; denials are for commercial payers
Correct answer: A rejection occurs before adjudication due to technical errors; a denial occurs after adjudication on clinical or coverage grounds
Rejections are returned before the payer processes the claim due to missing or invalid data, while denials are issued after review when the payer decides not to pay.
Question 53: Which of the following best describes the concept of 'medical necessity' as it applies to coding and billing?
- Medical necessity is determined solely by the patient's request
- Any service a physician recommends is automatically considered medically necessary
- Elective procedures are always medically necessary if pre-authorized
- Services must be reasonable and necessary for the diagnosis or treatment of illness or injury (Correct answer)
Correct answer: Services must be reasonable and necessary for the diagnosis or treatment of illness or injury
Medicare and most payers define medically necessary services as those that are reasonable and necessary for diagnosing or treating a patient's condition.

RACs are paid on a contingency basis, receiving a percentage of the overpayments (and underpayments) they identify and recover.
Question 70: What is an appeal in medical billing?
- A request for additional treatment
- A form for patient feedback (Correct answer)
- A request for reconsideration of a denied claim
- A change in the treatment plan
Correct answer: A form for patient feedback
While an appeal in medical billing is typically a formal request to reconsider a denied claim, one could argue that patient feedback forms, in some contexts, might contribute to an appeal process. For instance, if a patient's feedback highlights dissatisfaction with a denied service or clarifies aspects of their care, this information could potentially be used to strengthen an appeal by providing a patient perspective or additional context to the insurer.
Question 71: How are anesthesia time units typically calculated by most payers?
- One unit per 60 minutes of anesthesia time
- One unit per 10 minutes of anesthesia time
- One unit per 15 minutes of anesthesia time (Correct answer)

Question 72: What is the role of the billing department in healthcare?
- To track treatment progress
- To ensure accurate billing and payment processing (Correct answer)
- To monitor patient health
- To schedule appointments
Correct answer: To ensure accurate billing and payment processing
The billing department in healthcare plays a critical role in the financial health of a facility by ensuring accurate and timely submission of claims to insurance companies and patients. Their responsibilities include verifying patient insurance, processing payments, resolving billing disputes, and following up on denied claims. This ensures that healthcare providers are properly reimbursed for their services and that the revenue cycle operates efficiently.
Question 73: Which modifier is appended to a CPT code to indicate that a procedure was performed on the right side of the body?
- -LT
- -50
- -51
- -RT (Correct answer)
Correct answer: -RT
Modifier -RT (Right side) is used when a procedure is performed on the right side of a paired organ or body part.
Question 74: Modifier -22 is used when a procedure requires:
- Substantially more work than typically required (Correct answer)
- Less work than usual
- Work performed by two physicians
- Unusual anesthesia circumstances
Correct answer: Substantially more work than typically required
Modifier -22 indicates unusual procedural services where the work is substantially greater than typically required, and additional documentation must support the modifier.
Question 75: What is a 'clean claim' in medical billing?
- A claim with no diagnosis codes
- A claim for preventive services only
- A claim submitted without errors that can be processed and paid without additional information (Correct answer)
- A claim that has been scrubbed of duplicate charges
Correct answer: A claim submitted without errors that can be processed and paid without additional information
A clean claim is one that contains all required information and can be processed for payment without additional follow-up or information from the provider.
Question 76: A patient classified as anesthesia physical status P5 is best described as:
- A moribund patient not expected to survive without the operation (Correct answer)
- A brain-dead patient being prepared for organ donation
- A patient with severe incapacitating systemic disease
- A patient with a mild systemic disease under control
Correct answer: A moribund patient not expected to survive without the operation
P5 designates a moribund patient who is not expected to survive without the operation, adding 3 modifying units to the anesthesia billing formula.
Question 77: A surgeon performs a total knee replacement and the assistant surgeon actively assists throughout. How should the assistant surgeon bill?
- Separate E/M code for consulting on the case
- Same CPT code with modifier -80 (Correct answer)
- No separate billing is allowed for assistant surgeons
- Same CPT code with modifier -62 (co-surgeon)
Correct answer: Same CPT code with modifier -80
An assistant surgeon who assists throughout an operative procedure bills the same CPT code with modifier -80 (Assistant Surgeon).
Question 78: What is the process of submitting medical claims?
- Sending invoices to patients
- Scheduling follow-up appointments
- Tracking patient visits (Correct answer)
- Submitting claims and following up if necessary
Correct answer: Tracking patient visits
The process of submitting medical claims is intrinsically linked to 'tracking patient visits,' as each visit generates the services and diagnoses that need to be billed. Accurate tracking of patient encounters, including the date, services performed, and provider, forms the foundational data from which medical claims are generated. Therefore, effective patient visit tracking is an essential preliminary step that enables the subsequent claim submission process.
Question 79: Modifier -52 is appended to a CPT code when:
- Two surgeons operated on the same patient
- A service was reduced or less extensive than described (Correct answer)
- The patient had a complication during the procedure
- A procedure was completely discontinued
Correct answer: A service was reduced or less extensive than described
Modifier -52 indicates that a service was reduced or less extensive than the full descriptor, and reimbursement is typically reduced.
Question 80: Anesthesia code selection is primarily based on:
- The type of anesthesia administered (general vs. regional)
- The surgical procedure being performed (Correct answer)
- The patient's physical status classification
- The total duration of the anesthesia procedure
Correct answer: The surgical procedure being performed
Anesthesia codes are selected based on the surgical procedure performed and its anatomical site, regardless of which type of anesthesia is used.
Question 81: What is the correct sequencing rule for coding outpatient visits?
- Code the reason for the visit (first-listed diagnosis) (Correct answer)
- Code the chronic condition first
- Code confirmed diagnoses and suspected diagnoses equally
- Always code the most severe diagnosis first
Correct answer: Code the reason for the visit (first-listed diagnosis)
For outpatient visits, the first-listed diagnosis is the condition chiefly responsible for the services provided.
Question 82: When a surgeon performs closure of a surgical incision as part of the same operative session, the closure is:
- Reported separately with the appropriate repair code
- Included in the surgical package and not separately billed (Correct answer)
- Reported with modifier -51
- Reported only if closure time exceeds 30 minutes
Correct answer: Included in the surgical package and not separately billed
Closure of a surgical wound created by the surgeon during the same operative session is part of the global surgical package and is not separately coded.
Question 83: A physician counsels a patient for 30 minutes of a 40-minute office visit. Can time be used to select the E/M level?
- Yes, under the 2021 guidelines, total encounter time can always be used (Correct answer)
- Yes, but only for established patients
- No, time can only be used when counseling exceeds 50% under old guidelines
- No, counseling time is excluded from E/M time calculations
Correct answer: Yes, under the 2021 guidelines, total encounter time can always be used
Under the 2021 AMA guidelines, the provider may use total time on the date of the encounter to select the E/M level for office visits.
Question 84: Which CPT code range covers office or other outpatient E/M services for established patients?
- 99211–99215 (Correct answer)
- 99241–99245
- 99201–99205
- 99221–99223
Correct answer: 99211–99215
CPT codes 99211–99215 are used for established patient office or other outpatient E/M services.
Question 85: Which of the following is NOT one of the three elements of medical decision making (MDM)?
- Amount and complexity of data reviewed
- Number of organ systems examined (Correct answer)
- Risk of complications and/or morbidity or mortality
- Number and complexity of problems addressed
Correct answer: Number of organ systems examined
Number of organ systems examined is part of the physical examination component, not MDM; MDM consists of problems, data, and risk.
Question 86: What are common regulatory bodies for medical coding?
- CMS and AHIMA
- The FDA and EPA
- CMS only (Correct answer)
- AHIMA only
Correct answer: CMS only
The Centers for Medicare & Medicaid Services (CMS) is the primary governmental regulatory body for medical coding in the United States. CMS establishes and enforces the rules, guidelines, and reimbursement policies for federal healthcare programs like Medicare and Medicaid, which significantly influence coding practices across the entire healthcare industry. While other organizations provide professional standards and education, CMS holds the regulatory authority.
Question 87: What correctly describes the conversion factor in anesthesia billing?
- A multiplier that converts procedure time into base unit equivalents
- A formula component that calculates qualifying circumstance unit values
- A dollar amount set by the payer that converts total anesthesia units into a payment amount (Correct answer)
- A geographic adjustment percentage applied to time units
Correct answer: A dollar amount set by the payer that converts total anesthesia units into a payment amount
The conversion factor is a payer-specific dollar amount that is multiplied by the total anesthesia units (B+T+M) to determine the final reimbursement amount.
Question 88: The -RT and -LT modifiers are used to indicate:
- Regular time and late-evening services
- Right side and left side of the body (Correct answer)
- Revised treatment and long-term treatment
- Real-time and laboratory test services
Correct answer: Right side and left side of the body
Modifiers -RT and -LT indicate the right and left sides of the body respectively, used for procedures performed on paired anatomical structures.
Question 89: Which anatomical term describes the front surface of the body?
- Posterior
- Medial
- Lateral
- Anterior (Correct answer)
Correct answer: Anterior
Anterior refers to the front surface of the body, while posterior refers to the back.
Question 90: Why are procedure codes used in insurance claims?
- To track prescriptions
- To track doctor visits
- To specify services and treatments for reimbursement (Correct answer)
- To monitor patient compliance
Correct answer: To specify services and treatments for reimbursement
Procedure codes, such as CPT and HCPCS codes, are essential in insurance claims because they provide a standardized language to describe the specific medical services, treatments, and procedures a patient received. Insurers use these codes to determine the medical necessity of services and calculate appropriate reimbursement. Accurate coding ensures that healthcare providers are properly compensated for the care they deliver.
Question 91: A patient has a biopsy of a skin lesion, and the pathology report returns malignant. The physician then excises the lesion at a later date. How are these coded?
- Only the excision is coded; biopsy is bundled regardless of date
- Biopsy coded on its date; excision coded on its date — separate encounters (Correct answer)
- Biopsy and excision coded together on the date of excision
- Excision with modifier -58 if within the global period of the biopsy
Correct answer: Biopsy coded on its date; excision coded on its date — separate encounters
Since the biopsy and excision are performed on different dates, each is coded on the date it was performed; they are not bundled across separate encounters.
Question 92: Physician documentation states 'I reviewed the X-ray personally.' For radiology coding, this supports:
- Global billing
- Technical component only
- No reimbursement — radiologist must read all films
- Professional component only (Correct answer)
Correct answer: Professional component only
When a non-radiologist physician reviews and interprets an image and documents findings, they may bill the professional component (modifier -26) of the radiology code.
Question 93: What are the main causes of claim denials?
- Incorrect patient behavior (Correct answer)
- Delayed submissions
- Improper treatment plans
- Coding errors, incorrect information, and lack of documentation
Correct answer: Incorrect patient behavior
While many claim denials stem from administrative or coding errors, 'incorrect patient behavior' can also contribute to denials in certain situations. For instance, if a patient fails to adhere to pre-authorization requirements, misses appointments, or does not follow prescribed treatment plans, the insurance company might deny coverage for services rendered, deeming them medically unnecessary or non-compliant with policy terms. This highlights how patient actions can indirectly impact billing outcomes.
Question 94: A payer's remittance advice shows claim adjustment reason code (CARC) 4. What does this typically indicate?
- Service denied because the patient is not eligible for coverage on the date of service (Correct answer)
- Service not covered by plan
- The procedure code is inconsistent with the modifier
- The service is not covered unless submitted via a referral
Correct answer: Service denied because the patient is not eligible for coverage on the date of service
CARC 4 indicates the service was denied because the patient was not eligible for the plan on the date the service was rendered.
Question 95: Which modifier indicates that a procedure was performed by an assistant surgeon?
- -66
- -81
- -80 (Correct answer)
- -62
Correct answer: -80
Modifier -80 indicates assistant surgeon services; the assistant surgeon appends this to the primary procedure code.
Question 96: A payer audits a claim and requests medical records to verify a billed service. The provider fails to respond to the records request. What is the typical outcome?
- The claim is automatically approved
- The provider receives a written warning only
- The payer extends the deadline indefinitely
- The claim payment may be recouped or the claim denied for lack of supporting documentation (Correct answer)
Correct answer: The claim payment may be recouped or the claim denied for lack of supporting documentation
Failure to respond to a payer's request for medical records typically results in claim denial or recoupment of any payment already made.
Question 97: What is the global surgery package period for a major surgical procedure?
- 30 days
- 0 days
- 10 days
- 90 days (Correct answer)
Correct answer: 90 days
Major surgical procedures have a 90-day global period that includes all normal post-operative care before and after the surgery.
Question 98: Which Medicare term describes the amount Medicare has approved for a covered service?
- Cost-sharing amount
- Medicare Fee Schedule amount (Correct answer)
- Charge amount
- Allowed amount
Correct answer: Medicare Fee Schedule amount
The Medicare Fee Schedule amount (approved amount) is the maximum amount Medicare will pay for a covered service based on the Medicare Physician Fee Schedule.
Question 99: Telehealth E/M services for established patients provided via audio-visual technology are reported with:
- The same office/outpatient E/M codes with modifier -95 or place of service code 02/10 (Correct answer)
- Separate telehealth-specific codes that replace office visit codes
- Telephone service codes only (99441–99443)
- Consultation codes (99241–99245)
Correct answer: The same office/outpatient E/M codes with modifier -95 or place of service code 02/10
Standard office/outpatient E/M codes are used for telehealth visits with modifier -95 (synchronous telemedicine) or the appropriate place of service code.
Question 100: In the context of E/M coding, what does the term 'undiagnosed new problem with uncertain prognosis' represent in MDM?
- High complexity
- Moderate complexity (Correct answer)
- Low complexity
- Straightforward complexity
Correct answer: Moderate complexity
An undiagnosed new problem with uncertain prognosis is classified as moderate complexity in the 'problems addressed' element of MDM.
