What 57100 covers

A clinician, commonly a gynecologist, takes a limited sample of vaginal mucosa for diagnosis, often from a localized area that appears abnormal on examination. The procedure may be performed in an office or a facility. The tissue is submitted for microscopic evaluation; the biopsy service is distinct from the laboratory’s examination of the specimen when that service is performed.

Choose this code for a simple mucosal biopsy, rather than the more extensive biopsy described by 57105 or an excision such as removal of a vaginal cyst or tumor. Document the sampled site, the reason for biopsy, and the work performed. This minor procedure has a 0-day global period, so same-day preoperative and postoperative care is 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% multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; 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.

57100 billing questions

When should 57100 be chosen instead of 57105?

Use 57100 for a simple, limited vaginal mucosal biopsy. Use 57105 when the documented biopsy is extensive.

Can the pathology examination be reported separately?

The biopsy is the tissue-sampling service. When a laboratory performs microscopic examination of the specimen, that pathology service may be reported separately, such as with 88305 when the specimen and service meet that code’s criteria.

Can 57100 be reported with vaginal colposcopy code 57421?

Code 57421 includes vaginal or cervical biopsy when performed as part of the colposcopy service. Do not separately report 57100 for that same biopsy.

Is modifier 50 appropriate for biopsies from both sides of the vagina?

No. CMS identifies bilateral adjustment as inappropriate for 57100; modifier 50 should not be used.

What documentation supports 57100?

Record the vaginal site sampled, the clinical reason for sampling, and that a simple mucosal biopsy was performed. The operative or procedure note should distinguish sampling from a more extensive biopsy or excision.

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.
