What 58805 covers

A gynecologic surgeon uses an abdominal route to reach and drain an ovarian cyst, on one or both ovaries. The service is generally performed in an operating room when the cyst is managed by drainage rather than removal of the cyst wall or ovary. The approach distinguishes this service from vaginal drainage and laparoscopic aspiration.

Choose the code based on the abdominal route and the procedure actually performed. The operative report should identify the ovarian site, approach, cyst findings, and drainage performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. The code is priced as bilateral, so modifier 50 does not increase payment. Assistant-at-surgery services may be paid; co-surgeons require supporting documentation, and team surgery 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.

58805 billing questions

When should 58805 be chosen over 58800?

Use 58805 when the ovarian cyst is drained through an abdominal approach. Code 58800 is for drainage through a vaginal approach.

Does 58805 include cyst removal?

It represents drainage, not excision of the cyst. When the surgeon removes the cyst rather than evacuating its contents, consider the applicable cystectomy code, such as 58925.

Should modifier 50 be appended for bilateral drainage?

CMS prices 58805 as bilateral, and modifier 50 does not increase payment. Document the side or sides treated in the operative report.

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

The day-before preoperative visit and 90 days of related postoperative care are included in the global period. Separate reporting depends on whether a service is outside the included care.

What happens when another procedure is performed in the same session?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation.
