Breast surgery
About 19301: Breast-conserving partial mastectomy
Report 19301 for breast-conserving surgery that removes a breast lesion with surrounding tissue, commonly for cancer or ductal carcinoma in situ.
A breast surgeon removes a lesion and a surrounding portion of breast tissue while preserving the remainder of the breast. This is commonly performed for breast cancer or ductal carcinoma in situ, in a hospital or ambulatory surgical setting. The operative report should identify the breast and site, the lesion being treated, and the extent of tissue removed. Axillary node surgery is a separate part of the operation when performed and may be reported with an appropriate node procedure code.
Select 19301 when the operation is a partial mastectomy, rather than a simple complete mastectomy or an excision reported as a breast lesion excision. The 90-day global period includes the day-before preoperative visit and related postoperative care through day 90. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

19301 billing questions
How does 19301 differ from 19302?
19301 describes breast-conserving partial mastectomy. Use 19302 when the operation also includes axillary lymphadenectomy.
Can sentinel node surgery be reported with 19301?
Yes, when a distinct sentinel lymph node procedure is performed during the encounter. The operative documentation should support the node procedure as well as the breast resection.
When is 19303 a better choice?
Use 19303 for a simple complete mastectomy, rather than an operation that preserves part of the breast.
How is bilateral 19301 reported?
CMS lists bilateral reporting with modifier 50 and payment at 150%. The operative record should support surgery on both breasts.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care through day 90.
What supports assistant-at-surgery payment?
Documentation must establish the medical necessity of the assistant at surgery.
