What 38215 covers
Stem-cell concentration is processing of a harvested hematopoietic cell product to increase the concentration of stem cells in that product. It is distinct from obtaining peripheral-blood stem cells from an allogeneic or autologous donor and from other product-processing steps, such as washing or cryopreservation. The service concerns the collected product rather than the donor’s collection procedure.
Medicare assigns status I to 38215: the code is not valid for Medicare reporting, and Medicare uses a different code to report and pay for this service. Do not report 38215 as the Medicare service line. Concentration is distinct from collection, preservation, washing, thawing, depletion, and administration, which are separately described services in this CPT code series.

38215 billing questions
How is concentration different from stem-cell collection?
Collection obtains the stem-cell product from the donor. Concentration is processing of the harvested product.
Is 38215 valid for Medicare billing?
No. Medicare assigns status I, meaning 38215 is not valid for Medicare reporting; Medicare uses a different code to report and pay for the service.
Is concentration the same as washing or cryopreservation?
No. Washing and cryopreservation are distinct processing steps; concentration describes a different treatment of the harvested product.
Which collection codes are related to this service?
Codes 38205 and 38206 describe allogeneic and autologous peripheral-blood stem-cell collection, respectively. They describe obtaining the product, while 38215 describes concentration.
How does concentration differ from depletion or thawing?
Concentration increases the stem-cell concentration in the product; depletion and thawing are different product-processing services.
