What 15111 covers
Code 15111 represents additional recipient-site area treated with an epidermal autograft on the trunk, an arm, or a leg. A surgeon or other qualified clinician prepares the wound and applies epidermal tissue or cells obtained from the patient. These grafts may be used when a wound requires epidermal coverage, including in burn and wound-care surgery, commonly in a hospital or ambulatory surgical setting.
Report this add-on code with the primary code for the initial treated area, 15110. Count each additional 100 square centimeters or part of that increment; for infants and children, the corresponding measure is each additional 1% of body surface area. The operative note should identify the recipient site, treated area, graft method, and total area supporting the reported units. CMS pays 15111 within the primary procedure’s global period, so it is not reported as a stand-alone service.
