CPT code 58925: Ovarian cystectomy, cyst removal, ovary preserved2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 58925 in California.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 58925 covers

A gynecologic surgeon removes a cyst from the ovary while preserving ovarian tissue. The procedure is generally performed in an operating room for a persistent, symptomatic, or otherwise surgically managed ovarian cyst. The operative approach matters: this code describes cyst removal by an open approach, while laparoscopic excision of an ovarian lesion is represented by a different code. The surgeon may send the removed tissue for pathologic examination.

Choose this code when the operative report supports cyst excision rather than ovarian biopsy, partial oophorectomy, or removal of the entire ovary. Document the treated ovary or ovaries, the cyst excision, and the extent of ovarian tissue retained. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. For multiple procedures in the same 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 payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
