Medical-necessity criteria Aetna generally applies

Aetna CPB 0364 (Allograft Transplants of the Extremities) addresses graft selection for ACL reconstruction rather than the underlying indication. Aetna considers allografts of the knee ligaments medically necessary as an alternative to autografts for knee-ligament reconstruction, but states there is inadequate evidence that tendon allograft is equally effective as autograft for primary isolated ACL reconstruction and that, due to disease-transmission risk, allograft should not be used for primary isolated ACL reconstruction. Allograft is supported for: (1) revision surgery where a prior autograft reconstruction failed; and (2) primary reconstruction of combined/multi-ligament injuries when an adequate autologous graft is not available.
