1. Mesenchymal Stem Cell Therapy/Bone Marrow Aspirate:
Aetna considers the use of mesenchymal stem cell therapy for spinal fusion and other orthopedic indications (e.g., long bone nonunions) experimental and investigational because there is insufficient evidence to support its use, especially its safety and long-term outcomes.
Aetna considers the use of bone marrow aspirate experimental and investigational for nonunion fracture and as an adjunct to spinal fusion.
