Donor Lymphocyte Infusion (CPB 0638, reviewed 2026-09-29)
Aetna considers donor lymphocyte infusion medically necessary for persons who have had a prior medically necessary allogeneic bone marrow or peripheral stem cell transplantation. Several uses are considered experimental, investigational, or unproven, including GCSF-stimulated donor lymphocyte infusions for relapsed disease, intrathecal donor lymphocyte infusion, modified donor lymphocytes, reduced-dose infusion for Epstein-Barr virus-related post-transplant lymphoproliferative disease, pre-transplant infusion of extracorporeal photochemotherapy-treated donor lymphocytes for solid organ transplant, and donor lymphocyte-derived natural killer cells for melanoma. The policy does not apply to FDA-approved chimeric antigen receptor therapy, which is addressed in CPB 0920 and CPB 0924.
