CPT code 15740 designates the surgical creation of an island pedicle flap — a local soft-tissue reconstruction that preserves a named vascular pedicle to transfer well-perfused tissue into a wound or defect. The code is used across reconstructive and wound-care practices and matters nationally because it documents a distinct, resource-intensive operative technique associated with complex wound management and plastic or reconstructive surgery.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for when the code is used, typical sites of service, and common billing considerations. The publication summarizes benchmark payment and coverage themes, highlights relevant coding and documentation points for accurately reflecting surgical complexity, and outlines potential policy updates and payer approaches that affect authorization and reimbursement pathways. The goal is to provide clinicians, coders, and policy stakeholders with a clear, national-level reference on the clinical intent and administrative handling of CPT code 15740.
