Summary & Overview
CPT 15111: Epidermal Autograft, Trunk/Arms/Legs (Additional)
CPT code 15111 denotes an epidermal autograft for the trunk, arms, or legs billed as an additional unit for each extra 100 cm2 or each additional one percent of body surface area (or for pediatric patients). This code is important nationally for reporting staged or supplemental grafting when the initial graft (for example, CPT 15110) does not encompass the full required donor or recipient area. Accurate use of 15111 affects coding granularity for burn care, wound management, and reconstructive procedures and supports appropriate clinical documentation and service-level accounting.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for epidermal autografting on the trunk, arms, and legs, the relationship between primary and additional procedure coding, and the typical sites where the service is delivered. The publication also outlines relevant diagnosis contexts such as thermal burns, pressure ulcers, and open wounds associated with grafting needs, and highlights adjacent codes used to report primary versus additional epidermal autograft services. This resource is intended to help coding professionals, clinicians, and policy analysts understand where 15111 is applied and how it fits into procedural coding for burn and wound reconstruction nationally.
Billing Code Overview
CPT code 15111 describes an epidermal autograft of the trunk, arms, or legs performed as an additional procedure. The code covers each additional 100 cm2 or each additional one percent of body area (or an infant or child) when grafting sites on the trunk, arms, or legs. This procedure is typically performed in a surgical setting and the common sites of service are operating room or ambulatory surgery center, with possible performance in inpatient surgical units depending on clinical context.
Clinical & Coding Specifications
Clinical Context
A 42-year-old male presents to a regional burn center after sustaining partial- and full-thickness thermal injuries to the anterior torso and bilateral thighs in a household fire. Wound care over the first 5–7 days demonstrates nonviable epidermis and exposed dermis over discrete areas totaling greater than the primary graft harvested area. The surgical team schedules an operative session for debridement and primary coverage using an epidermal autograft for the trunk and legs. The procedure performed is an initial primary epidermal autograft for the trunk and legs billed with 15110, with one or more additional graft segments (each additional 100 cm2 or additional one percent body area or pediatric grafts) reported separately with 15111 as appropriate.
Preoperative workflow includes wound assessment and mapping, informed consent, anesthetic planning (general or regional), and photographic documentation. Intraoperative steps include tangential debridement of nonviable tissue, hemostasis, harvesting of epidermal grafts from a donor site (typically thigh), preparation and placement of the epidermal grafts to recipient sites on the trunk and legs, and securement with appropriate dressings. Postoperative workflow includes serial dressing changes, pain control, physical therapy as indicated, outpatient wound clinic follow-up, and documentation of graft take. Typical payors include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare. Typical sites of service are an inpatient operating room or ambulatory surgical center depending on patient stability and extent of injuries.
