CPT 15003: Additional Skin-Graft Site Preparation (Additional 100 cm2)
CPT code 15003 denotes an additional unit of surgical preparation of a skin-graft recipient site — specifically extending an already prepared area by another 100 cm2 on the trunk, arms, or legs (or an additional 1% body area per unit in children under 10). This code matters nationally because it standardizes billing for incremental operative work during skin-graft procedures for burns, open wounds, and scar contractures, supporting accurate coding for complex reconstructive and burn care across inpatient and outpatient surgical settings.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for code use, how the code relates to initial preparation codes for skin grafts, and the typical sites of service. The publication also summarizes common ICD-10 diagnoses associated with the procedure and lists related CPT service codes for the initial 100 cm2 preparation and for anatomically distinct areas.
This summary equips coding professionals, surgical practices, and billing teams with the clinical framing and coding relationships needed to identify when 15003 applies and where it fits within skin-graft preparation coding sequences. Data not available in the input includes payer-specific coverage rules and reimbursement benchmarks.

Billing Code Overview
CPT code 15003 describes an extension of a skin-graft preparation procedure when, in the same encounter, the provider has already prepared 100 cm2 of a body part with an open wound, burn eschar, or scar contracture to receive a skin graft. The code applies when the provider extends the prepared site by an additional 100 cm2 for adults and children aged 10 and older; for children under 10, it applies to each additional 1 percent of body area after the first.
Service type: Surgical skin-graft site preparation
Typical site of service: Trunk, arms, or legs
National Reimbursement Benchmarks
Medicare’s national mean of $76.70 sits close to commercial averages but below BUCA’s mean of $372.00, indicating BUCA reimburses substantially higher on average for CPT 15003 than Medicare. The gap between Medicare and BUCA highlights that commercial contracting can yield materially higher mean rates versus the public payer, with BUCA’s central tendency (median $380.20) far above Medicare’s median of $77.
Dispersion measured by the interquartile range (P75 minus P25) is widest for Blue Cross Blue Shield at $505.60 (P75 $838.90 minus P25 $348.30), followed by BUCA at $292.00 and UnitedHealth Group at $64.70? Correction: UnitedHealth Group’s IQR is $65.70 (P75 $131.50 minus P25 $66.30). The tightest IQRs are Medicare at $8.00 and Aetna at $36.20, indicating much more concentrated mid‑range pricing for those payers.
