What 15131 covers

This add-on code covers additional recipient-site area treated with a dermal autograft on the trunk, an arm, or a leg. A surgeon, commonly a plastic, reconstructive, or burn surgeon, may use the graft to cover a wound after burn injury, trauma, or excision. The graft is the patient’s own dermal tissue; the code distinguishes this method from split-thickness and epidermal grafting.

Report 15131 with the primary dermal autograft code 15130 when the treated area extends beyond the first 100 square centimeters. Each additional 100 square centimeters, or part of that increment, is reported as an additional unit. The operative report should identify the graft type, recipient-site location, and total area treated so the initial and additional portions can be supported. CMS classifies this as an add-on code: it is billed only with a primary procedure and paid within that procedure’s global period.

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.

15131 billing questions

Which primary code is reported with 15131?

Report 15131 with 15130 for dermal autografting of the trunk, arms, or legs. It represents area beyond the first 100 square centimeters.

How is the additional area counted?

Each additional 100 square centimeters, or any part of that increment, supports one unit. Document the total grafted area and the portion represented by the primary code.

Can 15131 be billed by itself?

No. It is an add-on code and must be reported with a primary procedure, such as 15130.

How does 15131 differ from 15136?

Both report additional dermal-autograft area, but 15131 is for the trunk, arms, or legs. Code 15136 is for the face, scalp, neck, hands, feet, or genitalia.

What documentation supports the units?

The operative report should specify the dermal autograft, recipient-site anatomy, and measured area treated. Those details support the primary and additional-area reporting.

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.
