Medicare covers certain hematopoietic stem cell transplants for specified diseases and circumstances. It does not provide general coverage for every procedure advertised as stem cell therapy or regenerative medicine. The medical condition, transplant type, evidence requirements, facility, and local coverage rules can all affect a claim.
Covered hematopoietic stem cell transplants
CMS has a National Coverage Determination for stem cell transplantation. It lists nationally covered uses of allogeneic and autologous hematopoietic stem cell transplantation. Covered indications include certain cases involving leukemia, aplastic anemia, severe combined immunodeficiency disease, Wiskott-Aldrich syndrome, multiple myeloma, and other listed conditions. CMS expanded national coverage in 2024 for certain patients with myelodysplastic syndromes who meet specified risk criteria.
Some uses are covered only in a Medicare-approved clinical study under Coverage with Evidence Development. Other uses are nationally noncovered. The CMS decision includes detailed criteria that cannot be reduced to a general statement that a diagnosis alone qualifies.
Regenerative injections and unapproved products
Clinics may use the term stem cell therapy for injections promoted for joint pain, arthritis, neurologic conditions, or other problems. A product described as using stem cells is not automatically covered by Medicare. FDA approval and Medicare coverage are separate decisions. Medicare may deny a service that is experimental, not reasonable and necessary, or outside a covered benefit.
Do not rely on a clinic’s general statement that Medicare will pay. Ask for the exact procedure and billing codes and request an Advance Beneficiary Notice when Original Medicare coverage is uncertain.
Costs and Medicare Advantage
Part A and Part B cost sharing depends on the transplant setting and related services. Medicare Advantage plans must cover Medicare-covered transplants but may require network facilities and prior authorization. A Medicare Advantage plan does not have to cover an unapproved or nationally noncovered use as a basic Medicare benefit.
What to do next
- Ask the treating specialist for the diagnosis, transplant type, and Medicare billing codes.
- Confirm that the facility and physicians participate in Medicare or the plan network.
- Check whether a Medicare-approved clinical study is required.
- Review the CMS National Coverage Determination for stem cell transplantation and FDA consumer alerts.

Coverage and costs can change each calendar year. Check current Medicare rules and current plan documents before receiving care. A provider’s estimate is not a Medicare coverage decision. Final payment depends on the claim and the applicable coverage requirements.
