What 15121 covers

This add-on represents additional recipient area covered with a split-thickness skin graft on sites such as the face, scalp, neck, hands, feet, genitalia, or multiple digits. The graft uses a thin layer of the patient’s own skin. Plastic surgeons, burn surgeons, and other surgeons may use it for reconstruction after burns, trauma, or excision, often in an operating room or hospital setting.

Use 15121 only with the initial-area code 15120. The additional area is counted in 100-square-centimeter increments, or in 1% body-area increments for infants and children. Document the recipient site, graft type, patient age when relevant, and the measured graft area supporting the units reported. CMS classifies 15121 as an add-on code: it is billed with a primary procedure and paid within that procedure’s global period.
