Autism / ABA Therapy Insurance Denied in Ohio? Here's How to Fight Back
Ohio enacted its autism insurance mandate in 2012, yet families across the state continue to receive ABA therapy denials, hour reductions, and supervisor ratio challenges from commercial insurers. This guide explains Ohio's protections, common denial tactics, and how to mount an effective appeal.
Ohio's Autism Insurance Mandate: HB 645
Ohio House Bill 645, effective November 2012, requires health insurers and HMOs to cover ABA therapy and other autism treatments for individuals with ASD. The mandate applies to individuals from birth through age 21.
Coverage limits: Up to $32,000 per year for individuals through age 6, and up to $18,000 per year for individuals age 7 through 21. These caps are written into statute, which means insurers can enforce them without violating the mandate — but they must still apply parity requirements for mental health benefits.
The Ohio Department of Insurance (ODI) regulates fully insured plans. Self-funded ERISA plans are exempt from state mandate but subject to federal Mental Health Parity Act (MHPAEA) Explained" class="auto-link">MHPAEA.
Common ABA Denial Tactics in Ohio
Dollar cap exhaustion: Ohio's annual caps ($32,000 for young children, $18,000 for older children) are reached quickly for intensive ABA programs. Families exhaust coverage mid-year and must either pay out of pocket or discontinue treatment.
"Not medically necessary" within the cap: Even before reaching the cap, insurers deny additional hours by claiming the requested intensity exceeds medical necessity standards.
Supervisor ratio disputes: Insurers deny claims for BCBA supervision hours that exceed their internal thresholds without clinical justification.
"Educational not medical": Insurers argue ABA is educational in nature and should be covered under the child's IEP. Ohio law and MHPAEA do not support this exclusion for medically prescribed ABA.
Network gaps: In rural Ohio, in-network BCBAs are rare, and insurers deny out-of-network claims even when no in-network provider is reasonably accessible.

How to Appeal an ABA Denial in Ohio
Step 1 — Request the denial with clinical criteria. Ohio requires insurers to provide the specific criteria used in the medical necessity determination. Get this in writing immediately.
Step 2 — Build your clinical documentation. Gather the ASD diagnostic evaluation (ADOS-2, CARS-2), the BCBA's current treatment plan, session data graphs demonstrating progress, a Vineland Adaptive Behavior Scales assessment, and a physician letter of medical necessity.
Step 3 — File an internal appeal. Submit your appeal citing HB 645, MHPAEA, AAP guidelines, and peer-reviewed ABA research. Request a peer-to-peer call between your BCBA and the insurer's medical reviewer. Ohio insurers must respond within 30 days (standard) or 72 hours (urgent).
Step 4 — Request an Independent Medical Review (IMR) with ODI. Ohio provides an External Independent Review: Complete Guide" class="auto-link">external review process through ODI after exhausting internal appeals. File at insurance.ohio.gov or call 1-800-686-1526. IRO decisions are binding on the insurer.
Step 5 — File an ODI complaint. File a consumer complaint with ODI to create a regulatory record. ODI investigates insurer compliance with HB 645 and MHPAEA.
Ohio Medicaid ABA and DODD Services
Ohio Medicaid covers ABA therapy for children under 21 as a medically necessary service through the EPSDT benefit. Coverage is provided through managed care organizations participating in Ohio Medicaid managed care. Contact your MCO to request ABA authorization.
The Ohio Department of Developmental Disabilities (DODD) administers home and community-based services for individuals with developmental disabilities, including autism. Key waiver programs include:
- Individual Options (IO) Waiver: Comprehensive community supports
- Level One Waiver: Supports for individuals at lower support needs
- Self-Empowered Life Funding (SELF) Waiver: Flexible self-directed supports
Ohio Autism Scholarship: Ohio also offers the Autism Scholarship Program, which funds educational services for school-age children with autism, including ABA, through approved providers. This is separate from insurance and Medicaid but can supplement coverage.
The Ohio Department of Aging (ODA) has limited autism-specific adult services. For adults, DODD waivers are the primary pathway.
