CPT code 38208 covers the clinical service of managing and preparing previously frozen hematopoietic progenitor cells (HPCs) for transplantation by thawing donor cells without washing away cryoprotectant. This procedure is central to autologous and allogeneic hematopoietic cell transplantation workflows and affects transplant program operations, supply chain for cell storage, and billing for cellular therapy services nationwide. Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find a concise explanation of the clinical procedure and expected sites of service, followed by payer coverage patterns and common billing considerations. The publication summarizes available national benchmarks where present, highlights relevant policy and coverage updates that influence payment and prior authorization requirements, and situates CPT code 38208 within the broader clinical context of hematopoietic cell transplantation. Operational impacts for transplant programs, including workflow implications of thaw-only preparation versus washed products, are also discussed.
