Summary
Aetna's Quantitative EEG (qEEG/Brain Mapping) policy (CPB 0221, effective 2026-04-14) establishes strict medical necessity criteria, covering qEEG only as an adjunct to traditional EEG for seven specific clinical scenarios (ambulatory recording, ICU monitoring, cerebrovascular evaluation, dementia/encephalopathy diagnosis, seizure screening, and pre-surgical epilepsy assessment). All other indications—including ADHD, depression, autism, anxiety, PTSD, concussion, and 30+ other diagnoses—are classified as experimental/investigational and not covered. Billing teams must immediately update claim submission logic to deny qEEG claims lacking one of the seven approved indications.
Action Required
By 2026-04-14: Billing team must implement claim edit rules in billing software to deny all qEEG claims (CPT 95961, 95962, S8040, and related EEG codes 95812-95830) unless the claim is linked to ONE of the seven approved clinical indications: (1) ambulatory EEG recording for expert interpretation, (2) ICU/OR continuous monitoring for acute intracranial complications, (3) cerebrovascular disease evaluation when imaging/routine EEG inconclusive, (4) dementia/encephalopathy diagnosis when initial evaluation unresolved, (5) ICU seizure screening, (6) long-term EEG seizure monitoring, or (7) pre-surgical epilepsy evaluation. Create a required diagnosis code mapping in the billing system linking approved ICD-10 codes (G40.001-G40.919 for epilepsy, F02.80-F03.C4 for dementia, I65.01-I69.998 for cerebrovascular disease, G92.00-G93.49 for encephalopathy, R56.1 for post-traumatic seizures). Reject all claims with diagnoses listed as experimental/investigational (F90.0-F90.9 for ADHD, F20.0-F20.9 for schizophrenia, F41.0-F41.9 for anxiety, F43.10-F43.12 for PTSD, F07.81 for post-concussion syndrome, and 30+ others per policy). Update prior authorization workflows to flag any qEEG request without documented medical necessity for clinical review. Notify providers and update coding guidelines documentation. Claims submitted without qualifying diagnosis codes will be denied as not medically necessary.
