CPT code 57558: D&C, cervical stump2026 Medicare rate & RVUs

Medicare pays $149.64 for 57558 nationally in the office and $113.90 in a hospital or facility. Local office rates run $133.12–$188.37.

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

What 57558 covers

A gynecologist dilates the canal of the cervical stump—the cervix left in place after a supracervical hysterectomy—and curettes tissue from it. The procedure may be performed when bleeding or another finding calls for tissue sampling from the retained stump. The specimen can be submitted for pathologic examination. It is distinct from curettage of a uterine cavity, which is not present after removal of the uterine body.

Report 57558 when the operative documentation supports dilation and curettage of the cervical stump, rather than a limited cervical biopsy or endocervical curettage. Document the prior supracervical hysterectomy, indication, site, and work performed. Medicare assigns a 10-day global period, so related postoperative visits during that period are included. 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. Modifier 50 is inappropriate; Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.
