What 56606 covers

This add-on represents tissue sampling from an additional, distinct lesion of the vulva or perineum after the primary lesion has been biopsied. A gynecologist or another clinician performing vulvar evaluation may obtain the specimen in an office, procedure room, or operating room. The tissue is typically submitted for histopathologic examination to investigate findings such as a persistent lesion or an area of abnormal vulvar tissue.

Report 56606 with the primary biopsy code 56605, not by itself, when a separate additional lesion is sampled. The record should identify the lesions and support that more than one distinct site was biopsied; repeated sampling of the same lesion is not an additional lesion. CMS classifies 56606 as an add-on code: it is billed only with a primary procedure and paid within that procedure's global period. The code does not represent a vulvectomy or removal of a larger area of vulvar tissue.

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.

56606 billing questions

When should 56606 be used instead of 56605?

Use 56605 for the primary lesion biopsy. Use 56606 for each additional distinct vulvar or perineal lesion biopsied during the service.

Can 56606 be reported by itself?

No. It is an add-on code and must be reported with the primary biopsy procedure, 56605.

What documentation supports an additional lesion?

Document the distinct lesion sites or describe how the sampled areas differ, along with the biopsy performed at each site.

How should units be determined?

Count additional distinct lesions biopsied beyond the primary lesion. Do not count multiple samples from one lesion as additional lesions.

Is a pathology examination included in 56606?

56606 describes the biopsy procedure. Histopathology of submitted tissue is a separate service when performed and reportable by the responsible pathology provider.

Does the add-on code have its own global period?

CMS pays 56606 within the primary procedure's global period; report it only with that primary procedure.

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.
