Summary
Aetna updated its Clinical Policy Bulletin 0158 (reviewed 2026-03-20) establishing strict medical necessity criteria for neuropsychological and psychological testing. The policy clarifies covered indications (cognitive impairment assessment, psychiatric differential diagnosis, treatment monitoring), defines specific CPT codes covered when criteria are met, and explicitly excludes coverage for pre-surgical clearance, educational testing, employment/disability/legal purposes, and computerized screening devices. Billing teams must ensure claims include documented medical necessity meeting Aetna's criteria or face denials.
Action Required
By April 20, 2026 (30 days from policy review date): 1) Billing team must update prior authorization workflows in billing system to require documented medical necessity for all neuropsychological/psychological testing claims using CPT 96116, 96121, 96125, 96130-96131, 96132-96133, 96136-96137. 2) Create or update claim submission checklist requiring providers to document: specific clinical indication (e.g., TBI assessment, psychiatric differential diagnosis, treatment-resistant symptoms), number of hours/units requested with clinical justification, validation of testing techniques for stated diagnosis, confirmation instruments are age/population-appropriate and current versions, and confirmation no redundant cognitive/behavioral measurements. 3) Providers and clinical staff must be trained to obtain medical necessity documentation BEFORE claim submission - claims lacking this documentation will be denied. 4) Implement system edits to reject claims for CPT 96116-96137 when submitted for excluded purposes: pre-surgical clearance, educational reasons, employment/disability/legal purposes, ADHD without neurological complication, chronic fatigue syndrome, migraines, substance abuse/active withdrawal cases, or neurodiversity assessment. 5) Update encounter forms/templates to flag these exclusions and remind providers of covered indications. 6) Deny or request additional documentation for any existing claims submitted without meeting these criteria.
