1. Procedure and CPT® Code Selection:

The patient underwent a percutaneous needle biopsy of the liver with ultrasound guidance to assess primary biliary cirrhosis.

Code 47000 is the CPT® code for a percutaneous liver biopsy. This code encompasses the biopsy procedure itself.

Ultrasound guidance is commonly inherent to biopsy procedures, and guidance is not separately reported if the main code (47000) includes the technique used.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code K74.5 is the correct code for primary biliary cirrhosis, which is specifically indicated in this case.

K74.3 is the code for other specified cirrhosis of the liver but is less specific than K74.5, making K74.5 the appropriate choice here.

3. Exclusion of Other Codes:

Code 47100 (option A) is for an open liver biopsy, which does not apply to this percutaneous procedure.

Codes 10005 (biopsy with imaging guidance) and 76942 (ultrasound guidance) would be redundant or incorrect since the main procedure code, 47000, sufficiently describes a percutaneous liver biopsy.

4. AAPC and CPT® Coding Guidelines:

AAPC guidelines state that guidance is included in certain biopsy codes when performed for the targeted organ, such as in 47000 for a liver biopsy.

Therefore, based on CPT® and ICD-10-CM coding rules, the correct answer is C. 47000, K74.5.
