Early Intervention and ABA in Missouri

Part C is your fastest first step

If your child is under 3 and you have concerns about development, you do not need a diagnosis to ask for help. Every state runs a federally required program called Part C early intervention, and Missouri's version is your quickest door. It is separate from insurance and ABA, and you can use it while you sort out other services.

Part C evaluates your child at no cost to you, and if they qualify, you get a plan and services. The goal is to support development in the early years, when the brain is most flexible.

How to request an evaluation

Call or write to Missouri's Part C program and say: 'I'd like to request an early intervention evaluation for my child.' You can do this without a doctor's referral or an autism diagnosis.

Put your request in writing if you can. Send an email or letter with your child's name, birth date, and your concerns. Keep a copy. The program must respond within a set timeline, usually 45 days from referral to evaluation. If you call, follow up in writing to have a record.

What happens after evaluation

If your child qualifies, a team meets with you to write an Individualized Family Service Plan, or IFSP. This plan lists your child's goals and the services they will get. It also names who provides them and how often.

Services happen in your home or in a community setting like a daycare or park. They are designed to fit your daily life, not the other way around. You are part of the team, and you decide what matters most.

• Services can include speech, physical, and occupational therapy
• Developmental intervention to build play, communication, and social skills
• Family training so you know how to support your child between visits

Cost and payment

Part C is free or low cost. Federal law says states must provide services at no charge or on a sliding scale based on your income. Missouri uses a sliding scale, so what you pay depends on what you earn. Many families pay nothing.

Your insurance is not billed for Part C. The program has its own funding. If you have private insurance, you can still use Part C without worrying about copays or deductibles.

Transition at age 3

At age 3, Part C ends and your child may move to school district services through an Individualized Education Program, or IEP. The transition starts around age 2 and a half, when your service coordinator helps you plan.

The school district evaluates your child to see if they qualify for preschool special education. This is a new system with different rules. You do not have to wait until the birthday to start the process, so ask your coordinator about timelines early.

Using Part C and ABA together

Part C and insurance-funded ABA are separate systems. You can use Part C first, add ABA later, or run both at the same time. Many families start with Part C because it is fast and low cost, then add ABA once they have a diagnosis and an insurance plan that covers it.

ABA is the intensive behavioral therapy that many autistic children receive. It is not part of Part C, but your Part C team can help you understand your child's needs and point you to resources. They cannot pay for ABA, but they can support your application.

Insurance coverage for ABA in Missouri

Missouri has an autism insurance mandate, but it only applies to state-regulated, fully insured plans. If your employer self-funds its health plan, the state mandate does not bind it, though many self-funded plans cover ABA anyway. Your plan document tells you which type you have.

Ask your insurer directly: 'Is my plan fully insured or self-funded? Does my plan cover applied behavior analysis for autism? What are the session limits, prior authorization rules, and annual caps?' Limits vary by plan, so get the exact numbers for your policy.

Medicaid covers medically necessary ABA for children under 21 through EPSDT. Your Medicaid plan name is on your member card. Call the number on the card and ask about ABA coverage and how to find a provider.

Finding ABA providers in Missouri

Missouri has the listings for this state. The largest concentrations are in St. Louis County, Jackson County, and St. Louis city. If you live outside those areas, you may have fewer options, but telehealth and travel can expand your choices.

When you call a provider, ask about waitlists, session hours, and whether they accept your insurance. Also ask about their experience with children under 3, since early intervention ABA looks different from school-age services.
