CPT 15120: Split-Thickness Autograft for Sensitive Areas, First 100 sq cm
CPT code 15120 is a critical billing code for split-thickness autograft procedures, specifically targeting complex and sensitive areas such as the face, scalp, hands, and genitalia. This procedure is essential in the treatment of severe burns, scar conditions, and other skin defects, particularly in infants and children. Nationally, the code is recognized by major payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare, ensuring broad coverage for patients requiring advanced skin replacement surgery.

This summary serves as a resource for understanding national trends and payer policies impacting split-thickness autograft billing and reimbursement.
CPT Code Overview
CPT code 15120 describes a split-thickness autograft procedure for skin replacement surgery. This code is used when grafting is performed on sensitive and complex anatomical areas such as the face, scalp, eyelids, mouth, neck, ears, orbits, genitalia, hands, feet, or multiple digits. The procedure covers the first 100 square centimeters or less, or 1 percent of the body area of an infant or child.
The service type is skin replacement surgery using autografts (split-thickness), which involves transplanting a thin layer of the patient's own skin to cover areas affected by burns, scars, or other conditions requiring skin restoration.
The typical site of service for this procedure is a Hospital Outpatient (POS 22) or an Ambulatory Surgical Center (POS 24), depending on payer and local policy guidelines.
Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an individual, often an infant or child, who has sustained a third-degree burn or has significant scar tissue on sensitive areas such as the face, scalp, eyelids, mouth, neck, ears, orbits, genitalia, hands, feet, or multiple digits. The patient is evaluated in a hospital outpatient or ambulatory surgical center setting. After assessment, the surgical team determines that a split-thickness autograft is necessary to replace damaged skin and promote healing. The procedure involves harvesting a thin layer of skin from a donor site on the patient's body and grafting it onto the affected area, covering up to 100 sq cm or 1 percent of the body area. Postoperative care includes monitoring for graft viability and infection.
