Summary & Overview
CPT 15151: Tissue Cultured Epidermal Autograft, Additional 1 cm2
CPT code 15151 denotes use of a tissue cultured epidermal autograft to cover an open wound or burn on the trunk, arms, or legs for each additional 1 cm2 of grafted skin after the initial 25 cm2 (up to an extra 75 cm2). This procedure-level code matters nationally because it captures incremental grafting area in complex wound and burn reconstructions, which impacts coding accuracy, clinical documentation, and payment for staged or extensive grafting procedures. Accurate reporting of incremental area is important for clinicians and billing teams managing advanced skin replacement therapies.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a consolidated view of how payers approach coverage for advanced epidermal autografts and what to expect in claims handling.
Readers will find a concise overview of the clinical context for tissue cultured epidermal autografting, guidance on appropriate use of CPT code 15151 in documentation, and benchmarks and policy updates where available. The report also highlights common modifiers used in procedural billing and notes areas where input data was not provided. Data not available in the input are identified explicitly so readers understand limits of the analysis.
Billing Code Overview
CPT code 15151 describes coverage of an open wound or burn on the trunk, arms, or legs using a tissue cultured epidermal autograft. This code is reported for each additional 1 cm2 of grafted skin after the first 25 cm2, up to an additional 75 cm2.
Service Type: Skin grafting using tissue cultured epidermal autograft
Typical Site of Service: Hospital operating room, ambulatory surgery center, or other procedural setting providing surgical wound or burn care

Clinical & Coding Specifications
Clinical Context
A 45-year-old male with a deep partial-thickness burn involving 60 cm2 of the right thigh following a workplace thermal injury undergoes surgical management. Initial debridement and wound bed preparation are performed in the operating room under general anesthesia. After adequate hemostasis and confirmation of a healthy granulating wound bed, a tissue-cultured epidermal autograft is applied. The first 25 cm2 is reported with the primary graft code (not shown here); 15151 is then used to report each additional 1 cm2 up to 75 cm2 of grafted skin beyond the initial 25 cm2, so this procedure will require multiple units of 15151 to account for the additional 35 cm2. Typical workflow includes preoperative evaluation, operative debridement, graft application, dressing placement, and postoperative wound care instructions with planned outpatient follow-up for graft assessment.
