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.

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.

57558 billing questions

When should 57558 be chosen over endocervical curettage?

Use 57558 when the clinician dilates and curettes the cervical stump. Endocervical curettage, 57505, describes sampling the endocervical canal without the stump D&C service.

How is 57558 different from a cervical biopsy?

A cervical biopsy, such as 57500, samples a localized area. Report 57558 when the documented procedure is dilation and curettage of the retained cervical stump.

Are related postoperative visits separately reportable?

Related postoperative visits during the 10-day global period are included in 57558.

Can modifier 50 be used for this procedure?

No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this anatomy and service.

Can an assistant or co-surgeon be billed with 57558?

Medicare does not pay an assistant at surgery for this code. Co-surgeon and team-surgery billing are not permitted.

What documentation supports reporting 57558?

Document the prior supracervical hysterectomy and retained cervical stump, the reason for sampling, and the dilation and curettage actually performed.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
