Getting Autism Therapy Covered by Insurance in Oregon

Oregon’s mandate

ORS 743A.190 requires state-regulated health plans in Oregon to cover the diagnosis and treatment of autism spectrum disorder, including applied behavior analysis.

Ages covered: Children under 18 with a pervasive developmental disorder, which Oregon defines to include autism spectrum disorder, developmental delay and developmental disability.

Dollar cap: No dollar cap in the statute. Be aware of the trade-off, though: Oregon expressly permits plans to impose treatment limitations on the number of visits or the duration of treatment, which several states forbid. A plan can be compliant here and still cap your hours.

The statute requires a plan to cover all medically necessary medical services, including rehabilitation services, that are otherwise covered under the plan — the entitlement is framed as non-discrimination rather than as a defined autism benefit. You will see a widely repeated claim that Oregon guarantees 25 hours a week of ABA as a floor; that language is not in ORS 743A.190, so ask your insurer to state its own hour limits in writing rather than relying on it.

Whether the mandate applies to your plan

This is the question to settle first, because the answer decides whether anything above is enforceable for you. State insurance mandates bind fully insured plans. Self-funded employer plans — where the employer pays claims itself and an insurer only administers them — are generally exempt under federal ERISA, and they cover roughly six in ten people with employer coverage.

Ask your HR department, in writing, which type your plan is. If it is self-funded, ORS 743A.190 does not compel coverage — but federal parity law may still help, and many large self-funded employers cover ABA voluntarily. Ask what the plan actually covers rather than assuming the answer is no.

The Medicaid route

The Oregon Health Plan covers ABA for members under 21 through EPSDT, and is not bound by the visit and duration limits a private plan may apply.

How Medicaid waivers work covers the route for families who do not qualify on income alone.

When you are denied

1. Get the denial reason in writing. Insurers must give a specific reason, and the appeal has to answer that reason rather than restate the diagnosis.
2. File the internal appeal within the deadline on the denial letter, with a letter of medical necessity that addresses the stated reason directly.
3. Request external review if the internal appeal fails. Fully insured plans carry external review rights, and an independent reviewer overturns denials more often than families expect.
4. Complain to the Oregon Division of Financial Regulation on 1-888-877-4894 if you believe ORS 743A.190 is being violated. Their consumer pages are here.
