What 58940 covers
A gynecologic surgeon removes part or all of an ovary through an open abdominal operation. Typical situations include an ovary that cannot be preserved because of torsion or a benign ovarian lesion. The procedure may involve one or both ovaries and may be performed in a hospital operating room or another surgical facility.
Choose this code when ovarian tissue is removed, rather than when a cyst is excised while preserving the ovary, a biopsy is taken, or a distinct oncologic operation is performed. The operative report should identify the tissue removed, the indication, the approach, and any additional procedures. CMS prices the code as bilateral, so modifier 50 does not increase payment. It has a 90-day global period that includes 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%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

58940 billing questions
How does 58940 differ from laparoscopic removal of an ovary?
58940 describes open ovarian removal. For laparoscopic removal of adnexal structures, consider 58661 when the documented procedure and approach fit that code.
Should modifier 50 be added when both ovaries are removed?
CMS already prices 58940 as bilateral, so modifier 50 does not increase payment. Document whether one or both ovaries were removed.
When is 58940 appropriate instead of ovarian cyst removal?
Use 58940 when part or all of the ovary is removed. If the surgeon removes an ovarian cyst while preserving the ovary, compare 58925.
What postoperative care is included in the global period?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
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 paid at 50%.
