Summary & Overview
CPT 38209: Preparation of Frozen Hematopoietic Progenitor Cells for Transplantation
CPT code 38209 represents the clinical service of preparing previously frozen hematopoietic progenitor cells (HPCs) for transplantation by thawing and washing to remove cryoprotective agents, hemoglobin, and debris. This code is important nationally as it captures a critical step in hematopoietic stem cell and bone marrow transplant workflows, impacting clinical readiness, resource use in transplant centers, and billing for specialized laboratory procedures. Key payers in national coverage discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical context for the code, typical sites of service, and the kinds of operational and billing considerations associated with HPC thaw/wash procedures. The publication provides benchmarks where available, notes on payer coverage patterns, and policy or coding updates that affect transplant program billing. It also outlines how the service integrates into transplant care pathways and what elements are typically documented to support claim submission. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 38209 describes the preparation of previously frozen and stored hematopoietic progenitor cells (HPCs) for transplantation. The procedure includes thawing each donor’s cells and washing them to remove the cryoprotective solution, hemoglobin, and cellular debris so the cells are ready for infusion into the recipient.
-
Service type: Cell processing and preparation for transplantation
-
Typical site of service: Hospital outpatient infusion center, transplant center, or specialized laboratory associated with hematology/oncology services
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient with relapsed non-Hodgkin lymphoma is scheduled to receive an autologous hematopoietic progenitor cell (HPC) transplant. The patient’s previously collected and cryopreserved HPC units are retrieved from the cell-processing laboratory. In the pretransplant workflow, the transplant coordinator verifies patient identifiers, donor/unit labels, and conditioning regimen timing. On the day of infusion, a clinical laboratory scientist or transfusion medicine specialist thaws each frozen HPC unit in a controlled water bath or validated dry-thaw device. After thawing, the provider performs a wash and concentration process to remove the cryoprotective agent (commonly dimethyl sulfoxide, DMSO), residual hemoglobin, and cellular debris to reduce infusion-related toxicity and hemolytic risk. Cell counts and viability testing are performed post-wash; samples for sterility and Gram stain may be obtained per institutional protocol. The processed product is then transferred to the transplant team for infusion through a central venous catheter in the inpatient bone marrow transplant unit or dedicated infusion center. Documentation includes unit identifiers, thaw and wash times, volumes before and after processing, cell viability, final cell dose infused, and any adverse events during processing or infusion.
