AAPC Updated CPC Exam Questions and Answers by aliyah

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.

00537 = Anesthesia for EP procedures

According to ICD-10-CM Guidelines, I11A.0 (Resistant hypertension) is used to indicate hypertension that remains uncontrolled despite the use of multiple antihypertensive medications. Resistant hypertension is coded to highlight the severity of the patient’s condition and the difficulty in managing their blood pressure. This code is added as a secondary code to reflect the persistent elevation of blood pressure despite medication.

A. I10 (Essential hypertension) is a general code for primary hypertension but does not specify resistance to treatment.

B. A code from category I27 is related to pulmonary heart diseases, not directly related to hypertension management issues.

D. A code from category I16 (Hypertensive crisis) is used for hypertensive emergencies or urgencies, which are acute episodes, not persistent uncontrolled hypertension despite treatment.

Thus, the correct answer is C. I11A.0, Resistant hypertension.
