What 57455 covers

During colposcopy, a gynecologist or other qualified women's health clinician examines the cervix under magnification, often after applying a solution that helps highlight abnormal areas. The clinician takes one or more tissue samples from suspicious cervical sites for pathology. This service is commonly performed in an office or outpatient setting after an abnormal cervical screening result or a concerning cervical finding.

Report 57455 once for the colposcopy session with cervical biopsy, regardless of the number of biopsy sites. The record should support the indication, colposcopic findings, sampled cervical sites, and specimen submission. When endocervical curettage is also performed, 57454 represents the combination; 57456 describes endocervical curettage without cervical biopsy. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. If related endoscopies are performed together, CMS endoscopy family pricing applies. Modifier 50 is inappropriate; assistant-at-surgery payment is restricted, and co-surgeon and team-surgery payment 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.

When cervical biopsy and endocervical curettage are both performed during the session, use 57454 for the combined service. Endocervical curettage alone is described by 57456.

Is 57455 reported once for multiple cervical biopsy sites?

Yes. Report one unit for the colposcopy session with cervical biopsy; the number of cervical sites sampled does not create additional units.

Can modifier 50 be used for biopsies on both sides of the cervix?

No. CMS identifies bilateral adjustment as inappropriate for this code, even when biopsies are taken from more than one cervical site.

What same-day care is included in 57455?

The 0-day global period includes same-day preoperative and postoperative care. The colposcopic examination is part of the biopsy service.

Can an assistant surgeon or co-surgeon be paid for 57455?

Assistant-at-surgery payment is restricted for this service. Co-surgeons and team surgery are not permitted.

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.
