CPT 38215: Hematopoietic Progenitor Cell Preparation

CPT code 38215 covers the preparation of hematopoietic progenitor cells (HPCs) by reducing plasma concentration and removing agranulocytes and the buffy coat layer to prepare a graft for hematopoietic stem cell transplantation. This code captures a specialized laboratory service that is central to the safety and efficacy of autologous and allogeneic hematopoietic transplants. Nationally, accurate coding for HPC processing supports appropriate billing, quality measurement and tracking of cellular therapy practices.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. Readers will find a concise overview of the clinical context for HPC processing, typical sites of service, and the operational role of this procedure in transplant workflows. The publication also surveys payer coverage patterns and benchmarking where available, highlights pertinent policy updates affecting cellular therapy billing, and summarizes common billing modifiers and documentation considerations. Data not provided in the input are noted as unavailable. This resource is intended to inform clinicians, coding professionals and administrators who manage billing and compliance for hematopoietic stem cell transplantation services.

Clinical & Coding Specifications

Clinical Context

A 45-year-old patient with relapsed non-Hodgkin lymphoma is scheduled for autologous hematopoietic progenitor cell (HPC) transplantation. The patient has completed mobilization with granulocyte colony-stimulating factor and underwent apheresis to collect peripheral blood stem cells. The laboratory service prepares the collected HPC product by reducing plasma volume and removing agranulocytes and the buffy coat layer to concentrate progenitor cells and reduce potential immunologic and infectious complications. The clinical workflow includes verification of donor/patient identifiers, product labeling, aseptic processing in a cellular therapy laboratory, cell counts and viability testing, infectious disease testing review, cryopreservation or immediate transfer to the transplant service, and documentation of the procedure and chain of custody. Typical sites of service are an inpatient bone marrow transplant unit, an outpatient hospital-based apheresis or cellular processing laboratory, or an ambulatory surgical center with a licensed cellular therapy facility.
