ABA therapy denials
Applied behavior analysis for autism is denied for hours, for age, for 'lack of progress', or as 'educational, not medical'. The appeal rests on the treatment plan, the assessment, and the coverage rules that apply to the plan.
What gets denied
- Initial authorization after an autism diagnosis
- Reduction in weekly hours at re-authorization
- Continuation after a fixed number of months
- Services for older children or adults
- Parent training or school-setting services
Common denial reasons
- Plan calls ABA 'educational' or 'not medically necessary'
- Treatment plan lacks measurable goals or a fade plan
- Assessment (for example ADOS-2 or comparable) missing or older than the plan allows
- Plan applies an age cap or hour cap
- Progress reports do not document goal mastery
How we approach the appeal
Obtain the plan's ABA criteria and compare them to the treatment plan. Ask the BCBA to document baseline, targets, progress data, and the clinical rationale for the requested hours. For self-funded plans, request the plan's comparative analysis of non-quantitative treatment limits under the parity rules and ask how the ABA limit compares to limits on medical services. For state-regulated plans, cite the state autism mandate by statute. Escalate to external review for medical-necessity denials.
Internal appeal: at least 180 days to file for commercial and employer plans; pre-service decisions within 30 days, urgent within 72 hours. External review within 4 months of the final internal denial for ACA-covered plans (45 CFR 147.136). Medicaid: fair hearing rights, typically within 90 days of the notice (42 CFR 431.221; state rules vary).
ABA is billed by the hour across many hours a week; a denied reduction over months is commonly a significant five-figure amount at billed charges.
