Many states have autism insurance laws, but they reach only state-regulated plans. Self-funded employer (ERISA) plans set their own rules and are exempt from state mandates. Ask member services whether your plan is fully insured or self-funded; that answer decides which rules apply to you. For children enrolled in Medicaid, ABA can be covered under EPSDT when a medical-necessity determination supports it. Ask your state Medicaid office what applies to your child. But the details matter: age limits, hour caps, diagnosis requirements, and what "coverage" actually means in practice vary enormously.

Ava's Law was expanded in 2019 from age 6 to age 20 and from $30,000 to $35,000. Does not apply to employers with ten or fewer employees.

ID Idaho
Mandate: Covered by Department of Insurance bulletin, not by statute (since plan year 2019)
Law: Dept. of Insurance Bulletin No. 18-02 (2 April 2018)
Age limit: None stated in the bulletin
Annual cap: None stated in the bulletin
Medicaid: Yes (EPSDT).
Idaho has no autism-specific statute, which is why a search of the insurance code finds nothing. The requirement lives in a Department of Insurance bulletin instead: treatments for autism cannot be excluded from coverage if rehabilitative or habilitative services are covered. It reaches individual, small-group, large-group and self-funded plans regulated by the Department, for plan years starting on or after 1 January 2019. It sets no age limit and no dollar cap of its own, because it works by forbidding an exclusion rather than by defining a benefit.
✓ Checked at the official state source on 2026-09-12 —

IMPORTANT SCOPE LIMIT: Iowa's ABA mandate reaches only employers with more than 50 full-time-equivalent employees, non-state public employee plans, and State of Iowa employee plans. Individual and small-group Iowa plans have no ABA mandate at all - so check your employer size before relying on this.

Law: SB 282 (bill number not yet verified — the code citation below is)

Annual cap: No dollar cap for commercial plans. Kansas limits ABA by HOURS: 1,300 hours per year for four years if diagnosed between birth and age 5, otherwise 520 hours per year under age 12. The hour limit can be exceeded with prior approval where medically necessary
Medicaid: Yes (EPSDT).

Law: PA 99 and PA 100 of 2012 (SB 414, SB 415)
Age limit: An insurer MAY stop treatment coverage after age 18. Nothing requires it to, and diagnosis coverage is not age-limited
Annual cap: The tiers are permissive: an insurer MAY cap ABA at $50,000/yr (through 6), $40,000/yr (7-12), $30,000/yr (13-18). A plan with no cap is fully compliant
Medicaid: Yes (EPSDT).

Law: Miss. Code Ann. § 83-9-26 (2015 session; effective for policies issued or renewed on or after 1 January 2016) (bill number not yet verified — the code citation below is)
Age limit: Under 22 for the mandate as a whole. Applied behavior analysis specifically is not required beyond age 8 — but everything else this section covers runs to 22
Annual cap: No dollar cap. The statute forbids dollar limits, deductibles or coinsurance less favorable than those applied to substantially all medical and surgical benefits. The one exception is an HOURS limit on ABA: 25 hours a week, of which no more than 10 may be with a licensed behavior analyst — and a plan above 25 hours must be covered where your physician or psychologist finds it medically necessary
Medicaid: Yes (EPSDT).
The limit on ABA is HOURS, not dollars, and it is not a hard ceiling: above 25 hours a week the statute requires coverage where a licensed physician or psychologist determines it is medically necessary. The insurer may review the treatment plan every six months and must pay for that review itself. This section does not apply to non-grandfathered individual and small-group plans that are already required to include essential health benefits.

Medicaid: Yes (EPSDT).
A separate clause makes the insurer accept a diagnosis made under the statewide standard through age 21; that 21 is NOT an eligibility limit. The individual-market section requires only that coverage be OFFERED.

Law: None located
Age limit: No autism-specific insurance mandate found in North Dakota law
Annual cap: No autism-specific mandate, so no statutory cap. A general mental-disorder mandate exists but does not name autism
Medicaid: Yes (EPSDT).
We searched the insurance chapters and the Century Code catchline index with a positive control. Federal parity rules and your plan terms may still require coverage - ask your plan and the ND Insurance Department. One thing this search could not see: a state can require autism coverage through an insurance-department BULLETIN instead of a statute, and a search of the statute books will not find it - that is exactly what Idaho turned out to have. We have not confirmed a bulletin here either way, so ask the ND Insurance Department directly rather than reading our 'not in the statutes' as 'not covered'.

OH Ohio
Mandate: Full mandate (since 2017)

Annual cap: No dollar cap. Coverage may not carry dollar limits, deductibles or coinsurance less favorable than for substantially all medical and surgical benefits. Minimums below age 14 include 20 visits/yr each for speech and OT, 20 hours/week of clinical therapeutic intervention, and 30 outpatient visits/yr

Age limit: Under 12
Annual cap: No dollar cap in the statute

Age 12 limit in the 2006 statute. TennCare provides broader Medicaid coverage. IMPORTANT: the Tennessee Department of Commerce and Insurance published a bulletin dated 1 August 2019 (tn.gov/content/dam/tn/commerce/documents/insurance/bulletins/8-1-19-Bulletin.pdf) and published reports say it requires coverage of medically necessary autism care including applied behavior analysis, beyond what the 2006 statute says. We confirmed that document exists on the Department's own site but could NOT read it - it is a scanned image - so we have not confirmed its contents and are not restating them here. If your child is over 12, do not stop at the statute: ask the Department whether that 2019 bulletin applies to your plan.

Bills that would create a Washington autism mandate are indexed online and read like law. They are not law. Coverage here comes from parity, not from an autism statute.

We read all 989 pages of Title 26 with a positive control. Federal parity rules and your plan terms may still require coverage - ask your plan and the Wyoming Insurance Department. One thing this search could not see: a state can require autism coverage through an insurance-department BULLETIN instead of a statute, and a search of the statute books will not find it - that is exactly what Idaho turned out to have. For Wyoming specifically there are credible published reports that the Insurance Department issued exactly such a bulletin on 19 April 2019 - barring plans that cover mental health from excluding evidence-based autism treatment, with compliance required by 1 July 2019. We have NOT been able to read that bulletin at the Department's own site, so we are not stating it as fact here. Ask the Wyoming Insurance Department directly whether a 2019 autism bulletin applies to your plan - and do not read our 'not in the statutes' as 'not covered'.
