What 57421 covers

A clinician uses a colposcope to inspect the entire vaginal canal and, when present, the cervix, then takes directed tissue samples from abnormal areas. Gynecologists commonly perform this in an office or outpatient facility when evaluating abnormal vaginal cytology, suspected vaginal intraepithelial lesions, or visible lesions requiring histologic assessment, including in patients who have had a hysterectomy.

Report the service when the examination covers the entire vagina and includes biopsy; the code accounts for the colposcopic examination and biopsy work. The record should identify the examined anatomy, the abnormal area sampled, and the clinical reason for sampling. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. 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. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery 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.

The biopsy is included in 57421 when performed as part of the colposcopic service. Document the sampled site and the reason for biopsy.

How does 57421 differ from 57455?

57421 covers examination of the entire vagina, with the cervix if present, and biopsy. 57455 is for cervical colposcopy with biopsy, rather than the entire-vagina examination.

Should modifier 50 be appended for biopsy on both sides?

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

Can an assistant or co-surgeon be billed with 57421?

Medicare does not pay an assistant at surgery 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.
