Getting Autism Therapy Covered by Insurance in Idaho

Idaho’s mandate

Idaho Department of Insurance Bulletin No. 18-02 (there is no autism statute), enacted 2018, requires state-regulated health plans in Idaho to cover the diagnosis and treatment of autism spectrum disorder, including applied behavior analysis.

Ages covered: None stated. Idaho did not pass an autism mandate — the Department of Insurance reached the same result by bulletin, so there is no statutory age ceiling to run into.

Dollar cap: None stated. The bulletin treats autism treatment as part of Idaho's Essential Health Benefits package under mental health and behavioral health treatment, which means limits must satisfy parity rather than a special autism cap.

Idaho is the unusual case: the requirement rests on a regulator's bulletin rather than a statute. The bulletin directs individual, small group and large group plans to cover evidence-based autism treatment including ABA for plans effective after 31 December 2018, and states that excluding autism treatment while covering occupational or speech therapy is discriminatory and prohibited. That last sentence is the one to quote. ABA must be delivered by a BCBA-certified provider.

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, Idaho Department of Insurance Bulletin No. 18-02 (there is no autism statute) 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

Idaho Medicaid covers medically necessary ABA for children under 21 through EPSDT. Note that Idaho has been moving children's behavior modification services out of managed care and into the state-run Children's Habilitation Intervention Services program — if your child's ABA is Medicaid-funded, confirm which system is paying before assuming continuity.

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 Idaho Department of Insurance on 1-800-721-3272 if you believe Idaho Department of Insurance Bulletin No. 18-02 (there is no autism statute) is being violated. Their consumer pages are here.
