What 19303 covers
A simple complete mastectomy removes the breast tissue and nipple-areolar complex without a formal axillary lymph node dissection. Breast surgeons typically perform it in a hospital or ambulatory surgical setting for breast cancer treatment or risk-reducing surgery. Sentinel lymph node sampling may be performed during the same operative session, but it is distinct from a full axillary dissection.
Report 19303 when the operative record supports removal of the whole breast rather than a partial mastectomy; document the extent of tissue removal and any axillary procedure separately. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For bilateral surgery, modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

19303 billing questions
How does 19303 differ from a partial mastectomy?
Use 19303 when the entire breast is removed. A partial mastectomy, reported with 19301, removes only part of the breast.
Does 19303 include axillary lymph node dissection?
No. A formal axillary dissection is not part of a simple complete mastectomy; choose the applicable mastectomy code when that dissection is performed. Sentinel node sampling is a distinct procedure.
Can sentinel lymph node biopsy be reported with 19303?
It may be reported separately when performed during the same operative session. The operative documentation should identify the node procedure and its extent.
How is bilateral 19303 reported for Medicare?
CMS identifies this as a bilateral procedure; modifier 50 is paid at 150%.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can breast reconstruction be performed and reported at the same session?
Immediate reconstruction may accompany mastectomy. The reconstruction code depends on the method, such as direct implant placement or tissue-expander placement, and the operative record should describe the work performed.
