Refer to the supplemental information when answering this question:View MR 005271What CPT® coding is reported?

CPT Code 55706: Biopsy, prostate; needle, transperineal, stereotactic template guided saturation sampling, including imaging guidance.

This code accurately describes the procedure performed. The documentation clearly states that a stereotactic template was used to guide the biopsy needles, and multiple samples were taken (saturation biopsies). This code includes imaging guidance.  

CPT Code 76942: Ultrasonic guidance for needle placement (e.g., biopsy, aspiration, injection, localization device), imaging supervision and interpretation.  

Although 55706 includes imaging guidance, code 76942 is also reported separately because the transrectal ultrasound provided initial diagnostic images and was then used for guidance during the biopsy. This is supported by the documentation which states "Using a B & K ultrasound probe, a transrectal ultrasound of the prostate was obtained. Once this was done...a biopsy needle is inserted into the prostate...under ultrasound guidance." This indicates distinct uses of the ultrasound.

Important Note: While some sources suggest that 76942 and the diagnostic transrectal ultrasound code (76872) are bundled, it's crucial to consult the latest National Correct Coding Initiative (NCCI) edits for the most up-to-date guidance.
