What 15136 covers
This add-on represents additional dermal autograft coverage at the face, scalp, neck, hands, feet, or genitalia after the initial area is reported. A surgeon or other qualified proceduralist places the graft on a prepared wound, such as a defect following excision or tissue loss from injury or burns. The code measures additional treated area, not another patient or separate encounter.
Report 15136 with the primary dermal autograft service, generally 15135, for qualifying sites. Select units using the additional grafted area; for infants and children, the measure is each additional 1% of body area. Documentation should identify the recipient site, graft type, total area treated, and the additional area represented by the units. CMS classifies this as an add-on code: it is billed only with a primary procedure, and its payment is within that procedure’s global period.
