Hematopoietic Cell Transplantation for Thalassemia Major and Sickle Cell Anemia (CPB 0626, reviewed 2026-09-18)
Aetna's Clinical Policy Bulletin 0626 considers allogeneic hematopoietic cell transplantation medically necessary for thalassemia major and sickle cell anemia in children or young adults when the member meets the transplanting institution's written eligibility criteria. Where no such criteria exist, Aetna considers it medically necessary for thalassemia major in children or young adults with a haploidentical or HLA-matched donor, and for sickle cell anemia when the member has a haploidentical or HLA-matched donor and either a history of stroke or an increased risk of stroke or end-organ damage. Autologous transplant for thalassemia major or sickle cell anemia in children or young adults, treosulfan-based T-cell depleted haploidentical transplant for sickle cell disease or transfusion-dependent thalassemia, and use of T-lymphocyte subsets at engraftment to predict acute graft-versus-host disease risk are considered experimental, investigational or unproven.
