UHC/Optum ABA Authorization Overview

UnitedHealthcare routes all behavioral health prior authorization requests — including ABA — through Optum, its behavioral health subsidiary. This means authorization requests go to Optum, not UHC directly.

The Optum Authorization Portal

Optum uses the Optum Provider Portal (provider.optum.com) for ABA prior authorization requests. Key features:

  • Online submission for initial and renewal authorizations
  • Real-time status tracking
  • Document upload capability
  • Secure messaging with the Optum utilization management team

    • 2026 Policy Updates

    Change 1: Standardized Assessment Requirement

    Optum now requires standardized assessment scores as part of every initial authorization request. Accepted assessments include:

  • ADOS-2 (Autism Diagnostic Observation Schedule, 2nd Edition)
  • ADI-R (Autism Diagnostic Interview-Revised)
  • CARS-2 (Childhood Autism Rating Scale, 2nd Edition)
  • Vineland-3 (Vineland Adaptive Behavior Scales, 3rd Edition)

    • A clinical narrative alone is no longer sufficient for initial authorization requests.

    Change 2: Telehealth Coverage Expanded

    Optum has expanded telehealth coverage for ABA to include 97155 (BCBA direct therapy) in all states where UHC operates. Previously, telehealth coverage for 97155 varied by state.

    Change 3: Concurrent Review at 6 Months for High-Intensity Cases

    Similar to Cigna's 2026 update, Optum now requires concurrent review at 6 months (rather than 12 months) for clients receiving 25+ hours per week of ABA services.

    • Common UHC/Optum Denial Reasons

    "Lacks medical necessity": Most commonly caused by a treatment plan that does not include measurable baseline data or specific, observable goals. Optum's medical necessity criteria are detailed in the Optum ABA Provider Resource Library.

    "Duplicate request": Optum's portal sometimes generates duplicate submission errors. If you receive this denial, call Optum to confirm whether the original request was received and is under review.

    "Provider not eligible": Verify that the rendering BCBA is credentialed with UHC/Optum and that their NPI is correctly listed on the claim.
