CPT code 15040 represents the harvesting of 100 cm2 or less of skin for a tissue-cultured skin autograft, a specialized surgical procedure used to obtain autologous skin for laboratory expansion and later grafting. This code is important nationally because tissue-cultured autografts are used in complex wound care, burn reconstruction, and cases where large areas of skin replacement are required but donor sites are limited. Proper coding affects clinical documentation, surgical claims processing, and downstream coverage determinations for staged reconstructive care.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical intent and typical service settings, followed by benchmarking and reimbursement context where available. The publication covers common modifiers and coding considerations, expected sites of service, and how CPT code 15040 fits within the broader pathway of cultured skin graft procedures. Additional sections outline payer-specific coverage patterns and claims adjudication considerations when available. This resource is intended to inform billing professionals, surgical teams, and policy analysts about the operational and policy relevance of CPT code 15040 at a national level.
