CPT code 49906 represents microsurgical harvest and transfer of an omental free flap for reconstruction of defects in locations such as the breast, head and neck, or extremities. This complex procedure involves detaching the omentum from its native abdominal vasculature and reconnecting vessels at the recipient site using an operative microscope. Nationally, the code matters because it denotes high-complexity reconstructive surgery with significant operative time, specialized surgical skill, and resource intensity, all of which affect coding, reimbursement, and utilization monitoring for payers and health systems.

Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for use of the omental free graft, common sites of service, and the service type. The publication provides benchmarks where available, summarizes policy and coverage considerations affecting access and coding practice, and highlights billing and documentation elements relevant to payers and providers. Data not available in the input is noted where applicable.
