How Missouri ABA Coverage Works

Missouri has a state autism insurance mandate. That mandate requires state-regulated health plans to cover medically necessary ABA therapy for autism. But it only applies to fully insured plans, which are plans your employer buys from an insurance company.

If your employer self-funds its health plan, the state mandate does not apply. Self-funded plans are governed by federal ERISA rules instead. Many self-funded plans still cover ABA, but they are not legally required to by the state. That is why two families at the same employer can get different answers about coverage.

Your plan type is on your insurance card or in your benefits summary. If you are not sure, ask your HR department directly.

The Exact Question to Ask HR

Before you call an ABA agency, get one answer from your employer. Ask: "Is our health plan fully insured or self-funded?" That single question tells you whether the state mandate applies to you.

If the plan is fully insured, you can rely on Missouri's autism mandate. If it is self-funded, you need to ask your benefits administrator what ABA coverage the plan includes. Do not assume the state mandate protects you.

What to Ask Your Insurance Company

Once you know your plan type, call the number on your insurance card and ask these specific questions. Write down the date, the representative's name, and the answers.

Ask: "Does my plan cover ABA therapy for autism?" Then ask: "What are the coverage limits, if any, for ABA?" Limits vary by plan, so do not rely on what a friend's plan covers.

Also ask: "Do I need a prior authorization for ABA?" and "What documentation do you require for approval?" Most plans require a formal autism diagnosis and a treatment plan from a qualified provider.

Prior Authorization and Documentation

Prior authorization is a common requirement. Your ABA provider will typically handle the paperwork, but you need to know what your plan expects. The process usually involves submitting a diagnosis, a treatment plan, and sometimes a letter of medical necessity.

Your insurance company has a specific deadline to respond, usually 15 to 30 days. If they ask for more information, provide it quickly. Keep copies of everything you submit.

If your claim is denied, you have the right to appeal. The denial letter will explain why and give you a deadline to appeal, often 180 days. Follow the instructions exactly and submit any additional evidence your provider can offer.

MO HealthNet for Eligible Families

If you qualify for MO HealthNet, Missouri's Medicaid program, ABA is covered for children under 21 when it is medically necessary. This coverage comes from the federal EPSDT benefit, which requires states to cover necessary services.

Your MO HealthNet plan name is on your member card. Contact your managed care plan or your caseworker to find ABA providers in your network. Coverage is not automatic, so you will still need a diagnosis and a treatment plan.

Finding ABA Providers in Missouri

Missouri has ABA agencies across many counties. The largest concentrations are in St. Louis County, Jackson County, and St. Louis city.

When you call an agency, ask if they accept your insurance and if they have experience with your specific plan. Also ask about waitlists, which can be long for in-demand services.

Common questions

Does Missouri law require all health plans to cover ABA?

No. Missouri's autism mandate applies only to fully insured plans. Self-funded employer plans are exempt under federal ERISA law, though many still choose to cover ABA. Check with your HR department to know which type you have.

What if my insurance denies ABA coverage?

You can appeal the denial. Your denial letter will explain the reason and the deadline to appeal, often 180 days. Submit any additional documentation your provider can offer, and consider asking your HR department for help if the plan is self-funded.

Does MO HealthNet cover ABA therapy?

Yes, MO HealthNet covers medically necessary ABA for children under 21 through the EPSDT benefit. Your specific managed care plan will have its own provider network, so check your member card for the plan name and call them for details.

How much does ABA therapy cost without insurance?

Costs vary widely, but ABA therapy typically ranges from $60 to $150 per hour. A full-time program of 20 to 40 hours per week could cost $5,000 to $25,000 per month. Many families rely on insurance or Medicaid to cover these costs.

What is the difference between fully insured and self-funded plans?

A fully insured plan is one your employer buys from an insurance company, and it must follow state mandates. A self-funded plan is one where your employer pays claims directly, and it is governed by federal ERISA law, not state mandates. Your HR department can tell you which you have.
