What 56405 covers

A clinician incises and drains a localized collection of pus in the vulvar or perineal tissues. The service may be performed by a gynecologist, family physician, or other qualified clinician in an office or facility setting. A vulvar soft-tissue abscess is an example; an abscess of the Bartholin gland has its own code. The documented site should distinguish the treated abscess from a Bartholin gland abscess and from an abscess elsewhere on the skin.

Report 56405 when the abscess is in the vulva or perineum and the service is incision and drainage. The record should identify the anatomic location and describe the drainage procedure. Related postoperative visits during the 10-day global period are included. When multiple procedures occur 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; co-surgeons are permitted, while team surgery is 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.

56405 billing questions

When should 56405 be used instead of 56420?

Use 56405 for an abscess in vulvar or perineal tissue. Use 56420 when the abscess involves the Bartholin gland.

What documentation supports 56405?

Document the abscess location in the vulva or perineum and the incision-and-drainage service performed. Clarify whether the Bartholin gland is involved.

Can modifier 50 be reported?

No. The descriptor and anatomy make modifier 50 inappropriate for this code.

Are related postoperative visits separately reported?

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

How are other procedures in the same session paid?

The highest-valued procedure is paid in full; other procedures are subject to the standard multiple procedure reduction.

Can an assistant or co-surgeon be reported?

Medicare does not pay an assistant at surgery for this code. Co-surgeons are permitted, but team surgery is not.

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.
