Summary

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.

Action Required

Action needed
Immediately: Billing team must implement prior authorization requirements for all DBS-related procedures (CPT 61850, 61860, 61863-61868, 61880, 61885-61888) and associated imaging (CPT 70551-70553). Before submitting claims: (1) Verify member meets ALL applicable medical necessity criteria based on diagnosis (tremor, motor complications, dystonia, or refractory epilepsy); (2) Confirm required documentation is present in medical record (e.g., UPDRS score ≥30 for Parkinson's motor complications, minimum 3 failed antiepileptic drugs for epilepsy, age ≥7 years for dystonia, age ≥18 years for epilepsy); (3) Confirm member does NOT have exclusion diagnoses (dementia, severe depression, cerebral atrophy, Hoehn and Yahr Stage V Parkinson's); (4) Route all DBS surgical claims through prior auth workflow in billing system before claim submission—failure to obtain prior auth will result in claim denials. Update encounter forms and clinical documentation templates to capture required screening elements. Do NOT bill experimental/investigational indications listed in policy (traumatic tremor, MS, Alzheimer's, autism, cerebral palsy, OCD, Tourette syndrome, chronic pain, etc.)—these claims will be denied. Educate providers on exclusion criteria and required documentation standards.
