CPT code 38207: Stem cell cryopreservation, freezing-based preservation2026 Medicare rate & RVUs

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 38207 covers

38207 identifies cryopreservation of stem cells in transplant-related processing. Cryopreservation preserves the cell product through freezing for later use. This is the preservation step, not collection of the cells or their later administration to a recipient. It is also distinct from post-collection processing such as thawing or washing. The code distinguishes one part of stem-cell handling from neighboring collection and processing services.

For Medicare, 38207 is not valid (status I); Medicare uses a different code to report and pay for this service. The code is in CPT Category I. Nearby codes distinguish related services: 38205 and 38206 describe blood-derived stem-cell harvesting for allogeneic and autologous use, 38208 describes thawing preserved cells, and 38209 describes washing a harvested product. Cryopreservation is a separate service from those collection, thawing, or washing steps.
