Summary & Overview

CPT 38205: Apheresis Collection of Hematopoietic Progenitor Cells

CPT code 38205 denotes the apheresis collection of hematopoietic progenitor cells (HPCs) from a donor’s peripheral blood using specialized apheresis equipment. This service is central to stem cell transplantation programs and cellular therapy supply chains, impacting hospital transplant services, donor centers, and outpatient apheresis units nationwide. Clear coding for HPC collection affects coverage determinations, claim adjudication, and operational workflows for transplant programs.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise national perspective on clinical context and billing practice for HPC apheresis, including where the service is typically performed and why accurate CPT coding matters for transplant programs and payer interactions. The publication covers reimbursement benchmarks, common billing modifiers and service-line considerations, and relevant policy or coverage trends that influence payment and authorization processes.

This summary provides clinicians, coding professionals, and revenue managers with a clear, policy-focused overview of CPT code 38205, what it represents clinically, and the payer landscape relevant to collections of hematopoietic progenitor cells.

Billing Code Overview

CPT code 38205 describes the harvesting of hematopoietic progenitor cells (HPCs) from the peripheral blood of a donor using apheresis equipment. The procedure involves collection of circulating progenitor cells through apheresis devices specifically designed for this purpose.

Service type: Apheresis collection of hematopoietic progenitor cells

Typical site of service: Hospital outpatient department, specialized apheresis center, or ambulatory surgical center where apheresis equipment and trained staff are available

Clinical & Coding Specifications

Clinical Context

A typical patient scenario involves a healthy volunteer or an allogeneic related/unrelated donor presenting to an apheresis unit for collection of hematopoietic progenitor cells (HPCs) via peripheral blood apheresis. The donor receives mobilization therapy (commonly granulocyte colony-stimulating factor) per the transplant center protocol for 4–5 days prior to collection. On the day of service the donor undergoes pre-procedure evaluation including vital signs, complete blood count, fluid status assessment, and central or peripheral venous access assessment. The apheresis team establishes vascular access (peripheral large-bore IVs or a central venous catheter if needed), connects the donor to an apheresis machine, and performs serial blood processing cycles to collect CD34+ enriched peripheral blood stem cells into a collection bag. Anticoagulant (e.g., ACD-A) is administered through the apheresis circuit. The procedure typically lasts 2–6 hours depending on target CD34+ cell dose, donor hematocrit, and flow rates. Post-procedure care includes monitoring for citrate toxicity, hemostasis at access sites, fluid replacement, and a post-collection complete blood count. Collected product is labeled, transported to the processing/transplant lab, and may undergo cryopreservation or immediate infusion for the recipient. Typical site of service is an outpatient apheresis center, blood center, hospital outpatient infusion suite, or specialized transplant unit. The service type is therapeutic/procedural outpatient apheresis for HPC collection. Donor or autologous scenarios: for autologous collections the patient is the recipient’s donor; for allogeneic collections the donor is separate from the transplant recipient.
