Reader Question:

Breast Biopsies

Question: Which types of breast biopsies are CPT 88305 and which are 88307?

Anonymous Texas Subscriber

Answer: CPT code 88307 for breast lesion excisions includes the descriptor requiring microscopic evaluation of surgical margins. This characterizes a procedure that entails a process similar to a partial or simple mastectomy, although the physician might describe it in other terms, such as a lumpectomy. On the other hand, CPT code 88305 for breast biopsy specifies that it does not require evaluation of surgical margins. It should be used to report the removal of discrete lesions not requiring margin checks, and other procedures such as an incisional or needle biopsy.
