CPT Code Overview
CPT code 15116 is used to report an epidermal autograft procedure for areas such as the face, scalp, eyelids, mouth, neck, ears, orbits, genitalia, hands, feet, and multiple digits. This code specifically covers each additional 100 square centimeters, or each additional one percent of body area for infants and children, performed as an add-on to the primary procedure. The typical site of service for this procedure is an outpatient hospital setting, reflecting its use in advanced skin replacement surgeries where precise grafting is required for complex anatomical regions.
Clinical & Coding Specifications
Clinical Context
A patient presents to the outpatient hospital with a chronic, non-healing wound on the lower leg, such as a non-pressure chronic ulcer or an open wound following trauma or surgery. The wound has not responded to conservative management and requires surgical intervention. The provider performs an epidermal autograft procedure to cover the affected area, starting with the first 100 sq cm (or one percent of body area for infants and children) using CPT code 15115. If the wound area exceeds this initial measurement, CPT code 15116 is used for each additional 100 sq cm or each additional one percent of body area. The procedure is typically performed by a surgery physician, plastic surgery physician, or family medicine physician, depending on the clinical scenario and patient needs.
