What 15837 covers

This operation removes redundant skin and underlying fatty tissue from the forearm or hand, then closes the surgical wound. Plastic and reconstructive surgeons may perform it after substantial weight loss when hanging tissue limits movement, complicates hygiene, or causes persistent skin irritation. The operative site must be the forearm or hand; removal of a discrete lesion or treatment of a wound is a different service.

Report the code when the operative work addresses excess skin and subcutaneous tissue at one of these sites. The record should identify the exact site, the clinical problem, and the tissue removed. This major surgery code has a 90-day global period that includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same 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 for this code. Assistant-at-surgery payment requires documented medical necessity; 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.

15837 billing questions

How is this code different from 15836?

This code is for excess skin and underlying tissue of the forearm or hand. Code 15836 addresses the upper arm.

Can it be used for removal of a skin lesion?

No. It describes removal of redundant skin and subcutaneous tissue for reconstructive contouring, not excision of a discrete lesion.

Is routine closure separately reported?

The code represents the forearm or hand excess-tissue operation, including the surgical closure that completes it. Do not treat routine closure as a separate service.

Should modifier 50 be used when both sides are treated?

No. CMS identifies bilateral adjustment as inappropriate for this code. Document the treated site or sites in the operative report.

What documentation supports reporting this service?

Record whether the site is the forearm or hand, the symptoms or functional problem from redundant tissue, and the tissue removed during surgery.

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.
