What 58951 covers
This major gynecologic oncology operation removes the malignancy along with both ovaries and fallopian tubes, the omentum, and pelvic lymph nodes. A total abdominal hysterectomy may also be performed as part of the operation. Gynecologic oncologists typically perform it in a hospital operating room for a patient with ovarian, tubal, or primary peritoneal cancer when the surgical plan includes pelvic lymphadenectomy but not the radical debulking work represented by higher-level family codes.
Report the code for the complete operative service, supported by the operative report’s description of the malignancy resection, bilateral adnexal removal, omentectomy, and pelvic node dissection. 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 are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation. Team-surgery payment is not permitted.

58951 billing questions
How does 58951 differ from 58950?
58951 includes pelvic lymphadenectomy with the cancer resection, bilateral salpingo-oophorectomy, and omentectomy. 58950 represents the corresponding resection without pelvic lymphadenectomy.
Is a hysterectomy separately reported?
A total abdominal hysterectomy may be part of the service represented by 58951 when performed. Review the operative report and the applicable coding guidance before considering a separate hysterectomy code.
Should modifier 50 be appended?
The code is already priced as bilateral, so modifier 50 does not increase payment.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation.
What documentation supports choosing 58951?
The operative report should support resection for ovarian, tubal, or primary peritoneal malignancy and document bilateral salpingo-oophorectomy, omentectomy, and pelvic lymphadenectomy. It should distinguish the work performed from radical debulking services in this code family.
