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.

How to choose

58950Cancer resection
Choose 58951 when pelvic lymphadenectomy is part of the malignancy resection; 58950 represents the related operation without that node dissection.
58952Cancer debulking
58952 includes radical dissection for debulking but not the pelvic lymphadenectomy represented by 58951.
58953Cancer debulking
58953 represents radical debulking with pelvic lymphadenectomy; 58951 represents pelvic lymphadenectomy without that radical debulking work.
58954Cancer debulking
58954 represents radical debulking with pelvic lymphadenectomy and para-aortic node sampling, a broader combination than 58951.

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.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
