Humana ABA Coverage Overview

Humana covers ABA services for members with autism spectrum disorder under its behavioral health clinical guidelines. Humana uses InterQual criteria as the basis for its medical necessity determinations, which is important to understand when preparing authorization requests.

InterQual Criteria for ABA

InterQual is a set of evidence-based clinical criteria used by many payors to evaluate medical necessity. For ABA, InterQual criteria focus on:

  • Severity of the ASD diagnosis and functional impairment
  • Specific behavioral deficits and excesses being targeted
  • Proposed intensity of services relative to the clinical presentation
  • Expected outcomes and discharge criteria

    • When preparing a Humana authorization request, frame your documentation in terms of InterQual criteria: document the severity of functional impairment, the specific behaviors being targeted, and why the proposed intensity is appropriate for the clinical presentation.

    Authorization Process

    Humana accepts prior authorization requests through:

  • Humana Provider Portal (provider.humana.com)

    Common Humana Denial Reasons

    "Does not meet InterQual criteria": The most common Humana denial. Review the InterQual ABA criteria and ensure your documentation addresses each criterion explicitly.

    "Frequency exceeds guidelines": Humana may deny high-intensity authorizations (30+ hours/week) without explicit justification for why lower-intensity services are insufficient. Include a statement in the treatment plan explaining why the proposed intensity is clinically necessary.
