CPT code 20816 represents the surgical replantation of a finger (excluding the thumb) after complete amputation. This complex, open reconstructive procedure is clinically significant because it aims to restore vascular continuity, tendon and nerve function, and digit viability — outcomes that directly affect patient function, rehabilitation needs, and long-term care costs. Nationally, the code is relevant to trauma systems, microsurgical teams, and payers managing high-cost, low-volume surgical episodes.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines clinical context for replantation, typical sites of service, and the types of utilization and coverage considerations commonly associated with major reconstructive procedures.

Readers will find benchmarks for use and payment context where available, a summary of policy themes affecting coverage decisions for complex reconstructive surgery, and clinical considerations that influence coding and site-of-service choices. Data not available in the input will be identified as such, and the report focuses on national-level implications for providers, health plans, and surgical programs involved in digit replantation care.
