Getting Autism Therapy Covered by Insurance in Arkansas

Arkansas’s mandate

Ark. Code Ann. § 23-99-418, enacted 2011, requires state-regulated health plans in Arkansas to cover the diagnosis and treatment of autism spectrum disorder, including applied behavior analysis.

Ages covered: ABA is limited to children under 18.

Dollar cap: $50,000 a year for ABA — a single annual limit, not the two age bands you will see reported. Everything else is protected: there are NO limits on the number of visits, and dollar limits, deductibles and coinsurance may be no less favorable than those applied to physical illness generally.

Check what kind of plan you have first. Arkansas defines 'health benefit plan' to cover group and blanket plans, including state and public school employee plans, but EXPRESSLY EXCLUDES INDIVIDUAL MAJOR MEDICAL PLANS. If you buy your own cover on the individual market, this mandate does not reach you. Two clauses are strong where it does apply: coverage may not be denied on the basis that treatment is habilitative in nature, and an insurer may not review medical necessity more often than it does for other illnesses — with the cost of any review borne by the insurer.

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, Ark. Code Ann. § 23-99-418 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

Arkansas Medicaid covers ABA for members under 21 through EPSDT. Because individual plans sit outside the mandate (below), Medicaid matters more here than in most states.

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 Arkansas Insurance Department on 1-800-852-5494 if you believe Ark. Code Ann. § 23-99-418 is being violated. Their consumer pages are here.
