What 19101 covers

A surgeon makes an incision in the breast and removes a tissue sample for diagnostic examination. This approach may be selected when a breast mass or other suspicious area needs tissue diagnosis and an open sample is performed instead of a percutaneous biopsy. The service is commonly performed by a breast surgeon or general surgeon in an operating room or other surgical setting, with the specimen sent for pathology examination.

Report this code for open incisional sampling, not when the procedure removes the breast lesion as a whole. The operative note should identify the breast and site, describe the open sampling approach, and document the tissue obtained. Related postoperative visits during the 10-day global period are included. For multiple procedures in one session, Medicare pays the highest-valued procedure in full and other procedures at 50%. For bilateral reporting with modifier 50, payment is 150%. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

Use 19101 for an open incisional sample obtained through a surgical incision. Code 19100 describes percutaneous breast sampling without imaging guidance.

How does 19101 differ from excision of a breast lesion?

19101 represents sampling of tissue through an incision. When the procedure removes the lesion rather than taking an incisional sample, consider an excision code such as 19120.

Can pathology be reported separately?

The tissue specimen may be examined and reported by a pathologist using an appropriate surgical pathology code, such as 88305, when the pathology service is performed.

How is bilateral breast biopsy reported?

CMS lists this as a bilateral procedure; modifier 50 is paid at 150%. The documentation should support open incisional biopsy on both sides.

Is an assistant surgeon payable for 19101?

No. CMS identifies a statutory restriction on assistant-at-surgery payment for this code. Co-surgeons and team surgery are also not permitted.

What postoperative care is included?

Related postoperative visits during the 10-day global period are included in the procedure.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
