Summary & Overview

CPT 15157: Tissue-Cultured Epidermal Autograft, Additional Area

CPT code 15157 represents placement of a tissue-cultured epidermal autograft for reconstruction of complex anatomical areas such as the face, scalp, eyelids, mouth, neck, ears, orbits, genitalia, hands, feet, and multiple digits. It is reported for each additional 100 cm2 of graft or each additional 1 percent of body area for infants and children after the initial 100 cm2. This code matters nationally as an entry point for billing advanced reconstructive techniques that address extensive soft-tissue loss from burns, trauma, or surgical defects.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical context, common sites of service, and the types of procedures to which it applies. The publication also outlines typical modifier usage and payer-specific coverage considerations where available. Additionally, the report summarizes benchmarking and reimbursement considerations, coding nuances for pediatric patients, and operational implications for surgical and hospital billing teams.

The content is intended to help coding professionals, practice managers, and policy analysts understand where 15157 fits in reconstructive surgical coding and the practical billing scenarios encountered nationally. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 15157 describes placement of a tissue-cultured epidermal autograft for reconstruction of the face, scalp, eyelids, mouth, neck, ears, orbits, genitalia, hands, feet, and/or multiple digits. The code is reported for each additional 100 cm2 of graft or for each additional 1 percent of body area for an infant or child after the first 100 cm2.

Service type: Surgical wound reconstruction using tissue-cultured epidermal autograft
Typical site of service: Operating room or procedure suite for reconstructive surgery of the face, head/neck, genitalia, hands, feet, and digits

Clinical & Coding Specifications

Clinical Context

A pediatric patient with extensive full-thickness facial and neck burns undergoes placement of a tissue-cultured epidermal autograft to restore epidermal coverage of the face and adjacent areas. The clinical workflow begins with inpatient burn stabilization, debridement and wound bed preparation under general anesthesia in the operating room. A small split-thickness skin sample is harvested and sent to a lab for epidermal cell culture. After sufficient epidermal sheet growth, the patient returns to the OR for placement of the cultured epidermal autograft. Intraoperative documentation includes graft surface area measured in square centimeters (or percent body surface area for infants/children), graft site(s) limited to face, scalp, eyelids, mouth, neck, ears, orbits, genitalia, hands, feet, and/or multiple digits, and any concurrent procedures. Postoperative care includes graft surveillance, dressing management, pain control, and outpatient follow-up for graft take and functional/cosmetic outcomes. Billing reflects the initial 100 cm2 (or 1% BSA pediatric increment) and uses additional units of 15157 for each extra 100 cm2 (or each additional 1% in infants/children) beyond the first unit.
