CPC practice question 3 of 10

A 55-year-old patient with suspected liver cancer was seen by the physician to obtain a biopsy. The special biopsy needle was placed using ultrasonic guidance. The physician obtained a small tissue sample from the liver, which was then sent to pathology. What CPT® codes are reported?

Answer options
A: 47000, 77002-26
B: 47000, 10005
C: 47100, 77012-26
D: 47000, 76942-26 Correct answer
Correct Answer:
D. 47000, 76942-26
Explanation

The procedure described is a percutaneous needle biopsy of the liver, which is correctly reported with CPT® code 47000. The physician used ultrasonic guidance to place the needle, which is a separate, reportable service. CPT® code 76942 is used for ultrasonic guidance for needle placement. The -26 modifier (Professional Component) is appended to 76942 to indicate that the physician provided only the supervision and interpretation for the guidance, and does not own the equipment, which is typical in a facility setting.

Why Incorrect

A. This is incorrect because CPT® code 77002 describes fluoroscopic guidance, not the ultrasonic guidance that was used in the procedure.
B. This is incorrect because CPT® code 10005 is for a fine needle aspiration (FNA) that includes ultrasound guidance; the scenario describes a tissue sample biopsy, not an FNA.
C. This is incorrect because CPT® code 47100 is for an open wedge biopsy of the liver, not a percutaneous needle biopsy, and 77012 is for CT guidance.

The section on the liver explains that CPT® 47000 is the appropriate code for a percutaneous needle biopsy. It also clarifies that any imaging guidance used during the procedure should be coded separately from the appropriate radiology section.

This chapter details the use of imaging guidance codes. It specifies that 76942 is the correct code for ultrasonic guidance for needle placement and that it is reported in addition to the primary procedure code (e.g.

47000). It also explains the application of modifier 26 for the professional component.
