1. Procedure and CPT® Code Selection:

The test performed is a quantitative, high-sensitive fluorescent enzyme immunoassay to measure specific IgE for recombinant peanut components.

CPT® Code 86008 is specific for allergen-specific IgE testing for recombinant or component-resolved allergens. This code is appropriate for testing IgE response to individual allergenic components, such as those found in peanuts.

2. Rationale for Excluding Other Options:

Code 86003 is used for allergen-specific IgE testing but does not apply to recombinant or component-resolved allergens, which are covered by 86008.

Code 86001 is for total IgE testing and does not measure specific allergens.

Code 86005 is for a general allergy screening (not specific IgE or component testing) and is not appropriate for component-resolved peanut allergen testing.

3. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, 86008 should be used for specific IgE testing related to recombinant allergens or component testing.

Therefore, the correct answer is C. 86008.

For bronchoscopy coding, you report the CPT code that describes thetype of scopeand thekey procedure performed. When bronchoscopicbiopsiesare performed, the service is reported with the appropriate bronchoscopy-with-biopsy code, and youdo not multiply the code by the number of biopsy samples. CPT codes for endoscopy procedures generally represent theoverall service, regardless of how many specimens are obtained during that one session at the same anatomic site category. In this question set,31628is the correct code representingflexible bronchoscopy with transbronchial lung biopsy(the biopsy component is the coded element).31625describes bronchoscopy with a different work element (not the biopsy service intended here), making it an incorrect distractor. Options that apply “×5” reflect a common novice error—billing per specimen rather than per procedure. On CPC exams, the presence of multiple biopsies is usually included to test whether you understand that endoscopic biopsy codes arenot reported per sample.

49083 – Abdominal paracentesis, diagnostic or therapeutic; with imaging guidance

This code includes imaging guidance (ultrasound or fluoroscopy).

Per CPT® guidelines, do not separately report fluoroscopy or ultrasound guidance with 49083.

The procedure was performed in the hospital, but CPT coding does not change based on site of service.

Why Other Options Are Incorrect:

A (49082) – Used without imaging guidance

B / D – Imaging guidance codes (77001, 77002) are bundled into 49083 per CPT® and NCCI edits

Official CPT® Guidance:

When a paracentesis is performed with imaging guidance, report 49083 only.

Newborn circumcision coding depends primarily on whether the circumcision is performed using aclamp/device techniqueversus asurgical excision technique. CPT54150is commonly associated with circumcision using a clamp or other device method (often described with a Gomco/Mogen-type approach in many training contexts). In contrast, CPT54160representssurgical circumcisionusing acircumferential incisionwith excision of the foreskin—matching the documentation (“circumferential incision… foreskin excised with a scalpel”). The infant’s age (8 days old) supports that this is a newborn service, but the decisive factor in this vignette is thetechnique described. Modifier-52(reduced services) is not supported because the full circumcision service is performed. Modifier-63applies to procedures performed on infants less than 4 kg for certain CPT codes when applicable, but it is not universally appended and is not the best answer here given typical CPC exam expectations for standard newborn circumcision technique identification. Therefore,54160is correct.

According to ICD-10-CM coding guidelines for substance use, abuse, and dependence, when multiple levels (use, abuse, and dependence) of the same substance are documented, only the highest level of severity is coded. The hierarchy is as follows: dependence > abuse > use.

D. If both use and dependence are documented, assign only the code for dependence is correct, as dependence represents the highest severity level and supersedes both use and abuse.

A. is incorrect because if both use and abuse are documented without dependence, only abuse would be coded as it is of a higher severity than use.

B. is incorrect because all three codes (use, abuse, dependence) should not be reported together; only the highest level should be coded.

C. is incorrect because if both abuse and dependence are documented, only dependence (the higher severity level) should be coded, not abuse.

Therefore, the correct answer is D. If both use and dependence are documented, assign only the code for dependence.

Thelunulais the pale, crescent-shaped area visible at the base of some fingernails and toenails (most commonly the thumb). It is part of thenail unit, associated with the nail matrix where nail formation occurs. Because the lunula is anail structure, a biopsy “of the lunula” is anail biopsy, even though a punch tool is also commonly used in skin biopsies. CPC exam questions frequently test precise anatomical vocabulary, especially for integumentary structures (skin, nail, hair). The distractors “eye” and “brain” are unrelated, and “skin” is tempting because punch biopsies are typically skin procedures; however, the question specifically identifies thelunula, which is not a skin landmark. Coding and documentation accuracy depend on knowing these terms because nail procedures often have different code families and clinical considerations than routine skin biopsies. Correct identification starts by mapping the term to its anatomical system: lunula → nail apparatus.

When a prior malignancy has been eradicated and the patient is no longer receiving treatment for the primary site, ICD-10-CM directs you to use apersonal history of malignant neoplasmcode rather than an active primary cancer code. Here, the breast cancer was treated successfully last year and no further therapy was required, so the breast cancer ishistory, not active. The new current condition ismetastatic cancer to the liver, which is coded as asecondary malignant neoplasm of liver and intrahepatic bile duct (C78.7). Because the primary breast cancer is not documented as active or under current treatment, you donotcode an active breast malignancy (C50.-). Instead, you addZ85.3 (personal history of malignant neoplasm of breast)to show the prior cancer history relevant to the current metastatic disease. Option A incorrectly codes a primary liver cancer. Option C incorrectly codes active breast cancer. Option D codes metastasis to the adrenal gland, not the liver.
