What 58950 covers
A gynecologic oncologist uses this code for surgery to remove ovarian, fallopian tube, or primary peritoneal malignancy together with both ovaries and tubes and the omentum. The operation is generally performed in a hospital operating room. This code describes the combination of cancer resection, bilateral salpingo-oophorectomy, and omentectomy; it does not describe a simple ovary removal or a diagnostic ovarian biopsy.
Select the code from the operative report’s documented diagnosis and the procedures actually performed. Documentation should identify the malignancy and describe removal of both adnexa and the omentum, as well as any additional work that could point to a different code in the resection family. The code is priced as bilateral, so modifier 50 does not increase payment. It has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How to choose
- 58940Oophorectomy
- 58940 describes removal of ovary or ovaries, rather than the malignancy resection with bilateral adnexal removal and omentectomy represented by 58950.
- 58951Ovarian cancer surgery
- Use 58951 when the documented resection also includes total abdominal hysterectomy along with bilateral salpingo-oophorectomy and omentectomy.
- 58952Cancer debulking
- 58952 is the related choice when radical dissection for debulking is performed; its descriptor allows omentectomy with or without that service.
- 58900Ovarian biopsy
- 58900 is an ovarian biopsy code for tissue sampling, not definitive resection of malignancy with bilateral adnexal removal and omentectomy.
