What 58943 covers

This operation removes one or both ovaries and the associated fallopian tube or tubes in surgery for ovarian, tubal, or primary peritoneal malignancy. Gynecologic oncologists most often perform it in a hospital operating room. The code identifies this malignancy-related removal, rather than ovarian cyst excision or a biopsy that samples tissue without removing the ovary and tube. The operative report should establish the malignancy-related indication and document which organs and sides were removed.

CMS assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. For additional procedures performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple-procedure reduction. The descriptor and anatomy make modifier 50 inappropriate; do not use it to represent bilateral work. Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation, while team-surgery billing is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

58940OophorectomyPartial or total, one or both
Use 58943 for malignancy-related removal that includes associated fallopian tube removal. Use 58940 for ovary removal without that specific malignancy-related tube-removal service.
58925Ovarian cystectomyCyst removal, ovary preserved
58925 is for ovarian cyst removal. It does not describe the malignancy-related ovary and tube removal captured by 58943.
58950Cancer resectionWith BSO and omentectomy
58950 represents a broader ovarian, tubal, or primary peritoneal malignancy resection service. Select it when the documented operation meets that broader scope rather than reporting only the service represented by 58943.
58900Ovarian biopsyTissue sampling only
58900 is for ovarian biopsy and tissue sampling. Choose 58943 when the operation removes the ovary or ovaries and associated tube or tubes for malignancy, rather than taking a diagnostic sample.

58943 billing questions

How is 58943 different from 58940?

58943 is for malignancy-related surgery that removes an ovary or ovaries along with the associated fallopian tube or tubes. 58940 describes ovary removal without that malignancy-related tube-removal detail.

Should modifier 50 be added when both sides are removed?

No. The descriptor and anatomy make modifier 50 inappropriate for this service.

What documentation supports reporting 58943?

The operative report should support the ovarian, tubal, or primary peritoneal malignancy indication and identify the ovary or ovaries and fallopian tube or tubes removed.

How does the 90-day global period affect postoperative visits?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team-surgery billing is not permitted.

What happens when other procedures are performed in the same session?

The highest-valued procedure is paid in full, and the other procedures are subject to the standard multiple-procedure reduction.
