For Mohs micrographic surgery, CPT® coding is based on the anatomic location of the lesion, the number of stages, and the number of tissue blocks per stage.

17311: This code is used for Mohs surgery on body areas such as the trunk, arms, or legs for the first stage.

17315: This is an add-on code used when more than five tissue blocks are examined in a single stage. Since this case involved six tissue blocks, 17315 is appropriate.

Explanation of incorrect answers:

A. 17313, 17314, 17315: Incorrect, as 17313 applies to the head, neck, hands, feet, or genitalia, not the arm.

C. 17313, 17315: Incorrect, as 17313 is not appropriate for the arm.

D. 17311, 17312, 17315: 17312 is used for additional stages beyond the first, which is not applicable here since only one stage was performed.

E. 85B2-335 is not a valid CPT code for Mohs surgery.

Thus, the correct answer is B. 17311, 17315, which accurately reflects a single-stage Mohs surgery with six tissue blocks on the arm.

1. Procedure and CPT® Code Selection:

The test ordered is a bile acid quantitation using an enzymatic method. This test measures the total bile acids in a patient with chronic hepatitis.

CPT® Code 82248 is specific for quantitation of bile acids, total, which is the correct code for a bile acid test using any method, including enzymatic.

2. Rationale for Excluding Other Options:

Code 82247 is used for the measurement of bilirubin, not bile acids, making it inappropriate for this test.

Code 82239 is for measuring an amino acid (gamma-glutamyl transferase), which is unrelated to bile acid quantitation.

Code 82252 is for a fecal bile acid screening, which is different from a quantitation of bile acids in serum or plasma.

3. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, 82248 should be selected for total bile acid quantitation regardless of the specific analytical method used.

Therefore, the correct answer is A. 82248.

50500 = Repair of kidney laceration

N99.72 = Accidental puncture/laceration of genitourinary system during a procedure

S37.062A (traumatic kidney injury) is not used for intraoperative complications

The nephrologist does not report the colectomy, nor modifier -80

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.

Lesion excision codes in the CPT® codebook include the removal of the lesion along with the necessary margins and a simple (nonlayered) closure when performed. These codes do not cover intermediate or complex closures, which are reported separately if performed. The measurement for selecting the appropriate lesion excision code includes the lesion and the margins required for complete excision.
