Gynecologic oncology surgery
About 58958: Recurrent gynecologic cancer debulking
Reports radical surgical debulking of recurrent ovarian, fallopian tube, or primary peritoneal malignancy, including extensive dissection and lymph node sampling.
A gynecologic oncologist reports this code for operative debulking of recurrent ovarian, fallopian tube, or primary peritoneal cancer when the procedure includes radical dissection and lymph node sampling. The operation may also include omentectomy, removal of both ovaries and fallopian tubes, and total abdominal hysterectomy. It is generally performed in a hospital operating room when recurrent disease requires substantial tumor removal and dissection.
Select the code based on the recurrent malignancy and the documented operative work, not simply the organs removed. The operative report should establish the recurrence, sites addressed, extent of dissection, lymph node sampling, and any included organ resections. This is a bilateral-priced code; modifier 50 does not increase Medicare payment. A 90-day global period includes the day-before preoperative visit and related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Assistant-at-surgery payment may be made; co-surgeons require supporting documentation, and team surgery is not permitted.

58958 billing questions
How does this differ from code 58957?
Both address recurrent ovarian, tubal, or primary peritoneal malignancy. Choose based on the operative service documented: this code describes radical debulking dissection that includes lymph node sampling, while 58957 describes extensive retroperitoneal dissection.
Can this be reported for a newly diagnosed ovarian malignancy?
This code is for recurrent ovarian, tubal, or primary peritoneal malignancy. Codes such as 58951 describe resection of ovarian malignancy with radical debulking work for a different disease circumstance.
Should modifier 50 be appended for bilateral work?
The code is already priced as bilateral under Medicare, so modifier 50 does not increase payment.
Are omentectomy, hysterectomy, and ovary removal separate services?
These may be performed as part of the debulking service described by this code. The operative report should identify which procedures were performed; do not assume each included procedure is separately reportable.
What documentation supports this code?
Document the recurrent malignancy, operative findings and sites treated, radical dissection, lymph node sampling, and any omentectomy, bilateral salpingo-oophorectomy, or hysterectomy performed.
How are other procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are subject to a reduction when performed in the same session.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
