CPT® Code 38208

Transplant preparation of hematopoietic progenitor cells (HPCs), also known as hematopoietic stem cells (HSCs), involves the critical process of thawing previously frozen cell harvests for use in stem cell transplantation. These cells, which are derived from blood and bone marrow, possess the unique ability to develop into various types of mature blood cells, including red blood cells, platelets, and white blood cells. The significance of HPCs lies in their application in treating various malignant neoplasms, such as leukemia and lymphoma, as well as other medical conditions like sickle cell disease. The procedure coded under CPT® 38208 specifically refers to the thawing of these blood-derived HPCs from a single donor, which have been preserved using a cryoprotectant solution and stored at low temperatures to maintain their viability. During the thawing process, the cells are immersed in a heated water bath, allowing for a controlled and effective thawing. Following this, a sample of the thawed cells is obtained for quality assessment, which is conducted by a qualified technician. This assessment may include evaluating the nucleated cell count, performing a differential count, checking cell viability, ensuring sterility, and/or conducting immunophenotyping. After the technician completes the quality assessment, the physician reviews the results to determine the suitability of the HPCs for the intended transplant procedure. It is important to note that CPT® 38209 refers to a similar process where the cells are not only thawed but also washed, which is necessary when multiple aliquots of harvested cells are involved, as it helps to remove excess cryoprotectant that could be toxic at higher concentrations.
