What 19100 covers

This service obtains breast tissue by passing a biopsy needle through the skin without imaging guidance. It is commonly used to sample a palpable breast mass or other localized abnormality when the clinician can identify the target by examination. A surgeon, breast specialist, or other qualified clinician may perform it in an office, clinic, or facility; the tissue is submitted for pathologic examination.

Select this code when the biopsy is percutaneous and performed without imaging guidance, rather than an open biopsy or an image-guided biopsy. The record should identify the breast target, the percutaneous approach, and that imaging guidance was not used. The 0-day global period includes same-day preoperative and postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
