What 56605 covers

A clinician takes tissue from one vulvar or perineal lesion for histopathologic evaluation, often using a punch or incisional sample when examination findings or symptoms warrant diagnosis. Gynecologists and other clinicians managing vulvar disease may perform the biopsy in an office procedure room or facility. Common reasons include evaluating a persistent ulcer, an abnormal pigmented area, focal thickening, or a lesion concerning for vulvar intraepithelial neoplasia or malignancy.

Report 56605 for the first lesion sampled and 56606 for each additional separately biopsied lesion. Document the lesion site and number, the clinical reason for sampling, and the biopsy performed. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in the same session, the highest-valued is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate, even for lesions on both sides. CMS does not pay an assistant at surgery for this service; co-surgeons are permitted, but team surgery is not.

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.

56605 billing questions

When should 56606 be reported instead?

Use 56605 for the first lesion biopsied. Report 56606 for each additional, separately sampled lesion.

Can modifier 50 be used for lesions on both sides?

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

Is the pathology examination included?

The code covers obtaining the biopsy tissue. Histologic examination is a separate laboratory service when performed and reported by the responsible laboratory.

What documentation supports the code?

Record the vulvar or perineal site, the number of lesions sampled, the clinical reason for biopsy, and the procedure performed.

How does CMS handle other procedures performed in the same session?

The highest-valued procedure is paid in full, with the other procedures subject to the standard multiple procedure reduction. Same-day preoperative and postoperative care is included in the 0-day global period.

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.
