Iowa drops all age and spending limits on autism insurance

Iowa rewrites its autism insurance rules

Iowa has eliminated all age limits and annual dollar caps on autism insurance coverage. Gov. Kim Reynolds signed House File 330 on June 11, 2025, and the changes take effect Jan. 1, 2026.

The bill passed the Iowa House 92-0 and the Senate 45-0, making it one of the least contested bills of the session.

Families who previously lost coverage when a child turned 19 or hit a spending cap now have broader protections.

The old law had tight limits

Iowa first required autism insurance coverage starting Jan. 1, 2018, under a law called HF 215. But that law came with restrictions.

State employee plans covered individuals only through age 20, and applied behavior analysis, or ABA, therapy in large group plans cut off at age 18.

Annual dollar caps ranged from $36,000 for young children down to $12,500 for teenagers. Once a patient aged out or hit the cap, families paid out of pocket or went without care.

HF 330 wipes out the old caps

The new law removes every age restriction, so adults with autism can now receive covered treatment for the first time. Annual and lifetime dollar caps are gone entirely.

Insurers can no longer limit the number of outpatient ABA therapy visits or visits with an autism service provider.

The law also updates the term “autistic disorders” to “autism spectrum disorder” to match current medical standards. These changes apply to fully insured group plans renewed or issued on or after Jan. 1, 2026.

Some minimums stayed the same

Not everything changed. Group plans must still provide at least 30 inpatient days per year and at least 52 outpatient visits annually.

Those minimums were already part of Iowa law before HF 330, and the new bill left them in place.

Plans may still include deductibles, copayments, and coinsurance, as long as the rates match what the plan charges for other medical services.

The core structure of coverage remains, just without the old spending ceilings.

The cost gap was enormous for families

ABA therapy is one of the most common treatments for autism, and it is not cheap. Without insurance, ABA therapy can cost between $62,400 and $249,600 per year, depending on the hours needed.

Under the old rules, a family with a child over age 13 could only get $12,500 per year in covered benefits. That gap left Iowa families paying tens of thousands of dollars out of pocket or pulling back on care.

Removing the caps means treatment decisions can now be based on medical need, not a dollar limit.

Not every plan falls under this law

HF 330 covers fully insured group health plans, state employee plans, and public employee plans. But self-insured employer plans are generally exempt under federal ERISA law, which limits what states can require.

Many large employers, typically those with more than 500 workers, use self-insured plans. Employees in those plans should ask their benefits office what their plan covers.

Individual marketplace plans are not directly addressed by this law either.

Thousands of Iowa families could benefit

The CDC estimates that about 1 in 31 children in the United States has been identified with autism spectrum disorder, based on 2022 data from 16 communities. That figure reflects a rise from 1 in 36 in 2020.

Autism is more than three times as common in boys as in girls.

Iowa does not have its own tracking site in the CDC’s network, but national trends point to thousands of Iowa families affected. The removal of age limits also opens coverage to adults who previously had no options.

Iowa law now lines up with federal rules

HF 330 also removes references to annual benefit limits to bring Iowa’s law in line with federal mental health parity rules.

The federal Mental Health Parity and Addiction Equity Act requires that mental health benefits be no more restrictive than medical and surgical benefits.

By cutting the dollar caps tied specifically to autism, Iowa’s law now better matches those federal standards. That alignment may also strengthen the legal position of Iowans who appeal denied claims.

Here is what families should do now

Families should start by checking their plan documents to confirm they have a fully insured plan subject to the new law.

Those already receiving autism treatment should verify whether their plan has renewed since Jan. 1, 2026.

Families previously denied coverage because of age limits should contact their insurer directly to ask about eligibility. The Iowa Insurance Division’s Consumer Advocacy team handles questions and disputes.

Iowa also has Regional Autism Assistance Program teams in all 99 counties that help families navigate services at no cost.

A separate state program is winding down

Iowa also runs its own Autism Support Program for families who do not qualify for private insurance or Medicaid ABA coverage. It serves children under 14 with household incomes up to 500% of the federal poverty level.

But a separate bill, HF 509, will phase out that program by July 1, 2027. Families currently enrolled will keep their services until the program ends.

The phase-out is based on the expectation that expanded insurance coverage and Medicaid will fill the gap.
