Early Intervention and ABA in Wisconsin

Start with Part C, not insurance

If your child is under 3 and you suspect autism or a developmental delay, Wisconsin's Part C early intervention program is the fastest door. It is federally required in every state, and you do not need an autism diagnosis to request an evaluation. That makes it a better first step than waiting for insurance preauthorization or a diagnostic appointment.

Part C and insurance-funded ABA are separate systems. You can use them in sequence or together. Many families start with Part C while they pursue an autism diagnosis and then add ABA through insurance once coverage kicks in.

How to request an evaluation

Call or write your county's Part C program and say you want an evaluation for your child. You do not need a referral from a doctor. Put your request in writing, even if you call first, and keep a copy. Include your child's name, birth date, and your concerns in plain language.

The program must respond within a set timeline, usually 45 days from referral to evaluation and eligibility decision. If your child qualifies, services start soon after. If they do not qualify, you can ask for a reevaluation later.

What an IFSP includes

If your child qualifies, you will work with a team to write an Individualized Family Service Plan (IFSP). This is a written plan that lists your child's developmental goals and the services they will get. It also names who provides each service, how often, and where.

The IFSP is family-centered. You set priorities, and services are delivered in your home or community settings like a daycare or park. Common services include speech therapy, occupational therapy, physical therapy, and developmental instruction.

Cost and payment

Part C services are free or offered on a sliding scale based on your income. In Wisconsin, some services may be free, and others may have a family fee. You cannot be denied services if you cannot pay.

Ask your service coordinator for the current fee schedule. They will also help you understand what your insurance might cover, but Part C cannot require you to use insurance first.

Transition at age 3

At age 3, Part C ends and your child may move to school-district services under Part B of IDEA. The transition starts at least 6 months before the third birthday. Your service coordinator will help you plan and connect with your local school district.

The school district will evaluate your child for preschool special education. If they qualify, they get an Individualized Education Program (IEP) with services like speech, OT, or specialized instruction. This is a separate process from insurance-funded ABA, and you can use both.

If your child is already getting ABA through insurance, that can continue after age 3. The school district does not pay for ABA, but they may provide related services. You can run both systems in parallel.

ABA options in Wisconsin

Wisconsin has ABA agencies across many counties. The largest concentrations are in Milwaukee County, Outagamie County, and Dane County. If you live in a rural county, you may need to travel or use telehealth.

Insurance coverage for ABA depends on your plan. Wisconsin's state mandate requires fully insured plans to cover autism treatment, but self-funded employer plans are exempt under federal law (ERISA). Many self-funded plans still cover ABA, so ask your HR department or insurer directly.

Ask your insurer this exact question: 'Does my plan cover applied behavior analysis for autism, and what are the session limits, prior authorization requirements, and annual caps?'
