What 19302 covers
The surgeon removes a portion of the breast, such as a tumor-bearing segment, and performs an axillary lymphadenectomy during the same operation. This breast-conserving cancer surgery is typically performed by a breast or general surgeon in a hospital or ambulatory surgical setting. It represents a more extensive service than breast excision alone because the axillary node dissection is part of the operation.
Select this code when the operative report supports both partial breast removal and axillary lymphadenectomy; a partial mastectomy with sentinel node evaluation alone is not the same service. Document the breast tissue removed and the axillary dissection performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For same-session multiple procedures, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.

19302 billing questions
When should this code be chosen instead of 19301?
Use 19302 when the operation includes both partial breast removal and axillary lymphadenectomy. For partial breast removal without that axillary dissection, consider 19301.
Does sentinel node biopsy support reporting 19302?
Sentinel node evaluation alone is not axillary lymphadenectomy. If the surgeon performs only sentinel node biopsy with partial mastectomy, 19302 is not the appropriate code for the breast procedure.
How is bilateral surgery reported?
For bilateral procedures, modifier 50 is paid at 150%.
What postoperative care is included in the global period?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be paid?
An assistant at surgery may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
