Deep Brain Stimulation (CPB 0208, reviewed 2026-03-27)
Aetna·Effective Mar 27, 2026
Aetna updated its Deep Brain Stimulation (DBS) medical policy (CPB 0208, reviewed 2026-03-27) establishing specific medical necessity criteria for DBS implantation across multiple indications including Parkinson's disease tremor, motor complications, dystonia, and refractory epilepsy. The policy defines required patient screening criteria, procedural codes covered when criteria are met, and clearly identifies experimental/investigational uses that will not be covered. Billing teams must ensure prior authorization reviews confirm all medical necessity criteria are documented before submitting DBS implantation and related procedure claims.
