What 57105 covers

An extensive vaginal mucosal biopsy removes tissue from a broad or multifocal abnormal area for histologic evaluation. Gynecologists and gynecologic oncologists may perform it in an office or facility setting when examination identifies suspicious vaginal mucosa, such as persistent lesions or changes concerning for vaginal intraepithelial neoplasia or malignancy. The code reflects the extent of the biopsy service, not simply a stated number of tissue fragments.

Choose 57105 rather than 57100 when the documented biopsy work is extensive. Record the lesion distribution and appearance, sites sampled, and extent of tissue collection. The code has a 10-day global period, so related postoperative visits during that period are included. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Do not append modifier 50 for bilateral vaginal biopsy. 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.

57105 billing questions

How does 57105 differ from 57100?

57105 is for extensive vaginal mucosal biopsy work; 57100 describes a simple biopsy. Document the extent and distribution of the sampled abnormal mucosa rather than relying only on the number of tissue fragments.

Can 57105 be reported with vaginal colposcopy and biopsy?

When 57421 is reported for vaginal colposcopy with biopsies, those biopsies are included in that service. Do not separately report 57105 for the same biopsy work.

Should modifier 50 be used for biopsies on both sides of the vagina?

No. The CMS bilateral adjustment does not apply to 57105, and modifier 50 is inappropriate.

Are related postoperative visits included?

Yes. Related postoperative visits during the 10-day global period are included in 57105.

What documentation supports choosing the extensive-biopsy code?

Document the abnormal mucosa's appearance and distribution, the sites sampled, and the extent of tissue collection. The record should show why the service was extensive rather than a simple vaginal mucosal biopsy.

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.
