Free Practice Questions for AAPC CPC Exam

CPT Code 00811: Anesthesia for lower intestinal endoscopic procedures, endoscope introduced distal to the splenic flexure; diagnostic, with or without collection of specimen(s) by brushing or washing

This code is reported for anesthesia services provided during a colonoscopy that is diagnostic in nature.

ICD-10-CM Code D62: Acute posthemorrhagic anemia

This is the most accurate postoperative diagnosis. The operative report states " Anemia due to acute blood loss. "

ICD-10-CM Code N18.6: End stage renal disease

This code captures the patient ' s documented history of ESRD.

ICD-10-CM Code Z99.2: Dependence on renal dialysis

This code is necessary to report the patient ' s dialysis status, as it affects the overall risk of the procedure.

Why other options are incorrect:

00812: This code is for therapeutic colonoscopies, not diagnostic.

D64.9: This code is for anemia, unspecified. D62 is more specific to the patient ' s condition.

K62.5: This code is for lower gastrointestinal bleeding, but the anemia is the primary diagnosis in this case.

Procedure Coding (CPT®):

69910 – Labyrinthectomy, complete; transmastoid approach

Provider performed:

Mastoidectomy

Complete destruction/removal of semicircular canals, utricle, and saccule

This is a complete labyrinthectomy, not partial

69990 – Microsurgical techniques, requiring use of operating microscope

Separately reportable with otologic procedures

Modifier -51 not required (add-on code)

Diagnosis Coding (ICD-10-CM):

H81.391 – Peripheral vertigo, right ear

Correct laterality and condition

Why Other Options Are Incorrect:

69905 – Partial labyrinthectomy

R42 – Symptom code (dizziness), not used when definitive diagnosis exists

56633 = Radical partial vulvectomy

Deep subcutaneous tissue involvement = radical, not simple

VIN II is coded as D07.1 (carcinoma in situ of vulva) per ICD-10-CM guidelines

Burn coding requires (1) code each burn site bylocation, laterality, and degree, and (2) add aTBSAcode when appropriate. The patient hasthird-degree burnsof both thighs (right and left), so the correct site/degree codes areT24.311A(third-degree burn of right thigh, initial encounter) andT24.312A(third-degree burn of left thigh, initial encounter). He also hassecond-degree burnsof the right anterior chest wall and the upper back, reported withT21.21XA(second-degree burn of chest wall, initial encounter) andT21.23XA(second-degree burn of back wall, initial encounter). TBSA is24%(falls in the 20–29% category), andthird-degree is 10%(falls in the 10–19% third-degree category), so the correct TBSA code isT31.21. Option D matches the required site/degree codes and the correct TBSA/third-degree percentage code pairing.

CABG coding is based on the number of conduits, not distal anastomoses

33533 = single arterial graft (IMA)

33518 is incorrectly listed here but is the closest exam-supported option

Anesthesiaphysical status modifiersare the ASA modifiersP1–P6, which describe the patient’s overall systemic health (e.g., P1 = normal healthy patient; P2 = mild systemic disease; up to P6 = brain-dead patient whose organs are being removed for donor purposes). Among the choices,P1is the only ASA physical status modifier.QSis an anesthesia modifier indicatingMonitored Anesthesia Care (MAC), not physical status.AAidentifies the anesthesia service performedpersonally by an anesthesiologist, which is a provider/service modifier, not a physical status.2Pis not an ASA physical status modifier; physical status modifiers are specifically formatted asP1–P6. CPC exam tip: separate anesthesia modifiers into categories: (1)physical status(P1–P6), (2)who provided/medical direction(AA, QK, QX, QY, etc.), and (3)service circumstancemodifiers (like QS for MAC when applicable). Here, the question explicitly asks for physical status—soP1is correct.

CPT biopsy codes for the skin are selected bytechniqueand whether the biopsy istangential (shave), punch, or incisional. In this scenario, three different biopsy techniques are performed onthree separate lesions: anincisional biopsyof a deep lesion (upper arm), apunch biopsy(forearm), and ashave biopsy(shoulder). The correct primary codes are11106(incisional biopsy, single lesion),11104(punch biopsy, single lesion), and11102(tangential/shave biopsy, single lesion). Because each is a distinct lesion and a distinct technique, CPT coding uses the appropriatebase codesfor each technique rather than “add-on additional lesion” codes, and you do not automatically apply modifier-51in CPT-answer logic unless the question specifically tests payer/claim-processing conventions. The CPC exam typically expects the straightforward reporting of all three correct biopsy codes when performed on separate lesions with separate specimens submitted. Therefore, optionBis the best match.

The provider documents history of COVID-19, not active COVID-19.

Z86.16 = Personal history of COVID-19

J18.9 = Pneumonia, unspecified organism

Codes U07.1 and U09.9 are for current or post-COVID conditions, which are not documented here. Therefore, A is correct.

1. Procedure and CPT® Code Selection:

The patient underwent a suppression study involving five glucose tests and five human growth hormone tests.

CPT® Code 80430 represents a suppression panel specifically for growth hormone studies, which includes various assessments for diagnosing abnormal growth.

CPT® Code 82947 is used for each glucose test performed, and since five glucose tests were conducted, it should be coded as 82947 x 5.

CPT® Code 83003 is used for each human growth hormone test performed, and since five tests were conducted, it should be coded as 83003 x 5.

2. Rationale for Excluding Other Options:

Option A lists 82947 x 2 and 83003 without sufficient units to account for the five tests each, which does not match the actual number of tests performed.

Option B omits the suppression panel code 80430, which is necessary for documenting the overall suppression study.

Option D does not provide the correct quantity of glucose and growth hormone tests, which were each performed five times.

3. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, when a suppression panel includes multiple components that are performed more than once, the specific panel code 80430 should be used along with the correct number of individual component codes.

Therefore, the correct answer is C. 80430, 82947 x 5, 83003 x 5.

To code for anesthesia services, we select the correct CPT® anesthesia code based on the procedure, modifiers, and physical status of the patient:

00800 represents " Anesthesia for procedures on the lower abdomen not otherwise specified, " which includes procedures like a panniculectomy. The code 00802 is not appropriate here because it is used for lower abdominal procedures involving " major lower abdominal vessels, " which does not apply to a panniculectomy.

AA Modifier indicates that the anesthesia services were personally performed by the anesthesiologist, as stated in the scenario.

P3 Modifier reflects a physical status of 3, which indicates a patient with a " severe systemic disease, " matching the patient ' s documented condition.

The emergency modifier 99140 is not appropriate here, as there is no indication that the procedure was performed under emergency conditions.

Thus, the correct answer is 00800-AA-P3.
