CPC Exam Dumps : Certified Professional Coder (CPC) Exam

This is destruction of malignant lesions (SCC).

17261 = Malignant lesion destruction, trunk/arms/legs, 0.6–1.0 cm

17262 = Same location, 1.1–2.0 cm

Feet are included in trunk/arms/legs.

Therefore, 17262, 17261 is correct.

36223 = Selective catheterization of common carotid with imaging

36227 ×2 = Bilateral external carotid angiography

In this encounter, the correct coding order follows ICD-10-CM guidelines for coding multiple conditions when AIDS (B20) is documented, as it takes precedence. The patient ' s diagnosis of AIDS, documented with code B20, is reported as the primary diagnosis since it is a chronic condition. The M17.31 code is used to document unilateral primary osteoarthritis of the right knee, unrelated to AIDS but causing the patient ' s knee pain.

Explanation of each answer choice:

A. B20, M17.31: Correctly lists AIDS (B20) as the primary diagnosis and osteoarthritis of the right knee (M17.31) as the secondary diagnosis.

B. Z21, M08.861: Z21 represents asymptomatic HIV, not AIDS, which is incorrect here, and M08.861 is the code for juvenile idiopathic arthritis, not relevant in this case.

C. M17.11, B20: Incorrect as M17.11 is for unilateral primary osteoarthritis of the right knee, not left, and does not prioritize B20 as required.

D. M17.31, B20: Incorrect because it does not list B20 as the primary diagnosis, which is necessary per coding guidelines when AIDS is documented.

Thus, the correct answer is A. B20, M17.31.
