Start with Part C, not insurance

If your child is under 3 and you suspect a delay or autism, Massachusetts Part C early intervention is the fastest door. It is federally required in every state, so it exists here too, and you do not need an autism diagnosis to request an evaluation. You can ask for an evaluation as soon as you have a concern, even before a doctor agrees.

Part C and insurance-funded ABA are separate systems. You can use Part C first, then add ABA later, or run them at the same time. Part C focuses on developmental support in daily life, while ABA targets specific behaviors and skills. Many families start with Part C and transition to ABA around age 2 or 3.

How to request an evaluation

In Massachusetts, you request an evaluation in writing. Send a letter or email to your local Part C program, which is often called Early Intervention. You can find the contact for your area through the Massachusetts Department of Public Health or by asking your pediatrician.

Your written request should include your child's name, date of birth, your contact info, and a simple statement like 'I am requesting an early intervention evaluation for my child.' Keep a copy. The program must respond within a set timeframe, usually 45 days from referral to evaluation, but ask for the exact timeline when you call.

What happens after the evaluation

If your child qualifies, you will work with a team to create an Individualized Family Service Plan (IFSP). This document lists your child's strengths, your family's concerns, and the services your child will receive. It is reviewed every six months and updated at least annually.

Services are delivered where your child naturally spends time: at home, at daycare, or in the community. A typical session might be a developmental specialist or speech therapist coming to your living room and coaching you on how to build skills into play and routines. You are part of the team, not a bystander.

Cost and payment for Part C

Part C is free or sliding scale, depending on your income. In Massachusetts, you may be asked to pay a fee based on family size and income, but no one is turned away for inability to pay. Some services are covered by Medicaid or private insurance, but the program cannot charge you more than a set amount.

Ask your local program for the current sliding scale and what documentation they need. You will not get a bill for the evaluation itself, and the IFSP services have a cap on what you can be charged, but the exact number changes, so ask directly.

Transition to school services at age 3

Part C ends on your child's third birthday. Around the time your child turns 2 and a half, your Part C team will start planning the transition. They will help you connect with your local school district, which is responsible for special education services for children 3 and up.

The school district will evaluate your child for an Individualized Education Program (IEP). If your child qualifies, services may include special education preschool, speech therapy, or ABA in a school setting. The IEP process is different from the IFSP, and the school district sets the timeline, so start early.

How ABA fits with Part C

Insurance-funded ABA is a separate system. In Massachusetts, a state mandate requires many private plans to cover ABA, but it only applies to fully insured plans. If your employer self-funds its plan, it is exempt under ERISA, though many still cover ABA. Check your plan documents or call the number on your member card.

Ask your insurer: 'Does my plan cover applied behavior analysis for autism? Are there limits on hours or visits per year? Do I need preauthorization?' Limits vary by plan, so do not rely on a general figure. If you have MassHealth (Medicaid), it covers medically necessary ABA for children under 21 through EPSDT, but you must use a provider in your plan's network.

You can use Part C and ABA at the same time. Part C might focus on communication and daily living, while ABA works on specific behaviors. Many families find that Part C helps them understand their child's development while they wait for ABA to start or while they figure out insurance coverage.

Common questions

Do I need an autism diagnosis to get Part C services in Massachusetts?

No. You can request an evaluation based on a concern, like delayed speech or unusual behaviors. The evaluation will determine if your child qualifies for Part C, which uses a developmental delay or established condition standard, not an autism diagnosis.

How much does Part C early intervention cost in Massachusetts?

It is free or sliding scale based on your income. You may pay a fee, but it cannot be more than a state-set cap, and no one is denied for inability to pay. Ask your local program for the current fee schedule.

What is an IFSP and how is it different from an IEP?

An IFSP is the plan for Part C services for children under 3. It focuses on your family's goals and is reviewed every six months. An IEP is for children 3 and up, provided by the school district, and focuses on educational goals. The transition happens around your child's third birthday.

Can I get ABA through Part C?

Part C does not typically provide intensive ABA therapy. It provides developmental services like speech, physical, and occupational therapy, and special instruction. For ABA, you usually need to go through your private insurance or MassHealth.

Does my employer's insurance have to cover ABA?

Not always. Massachusetts requires state-regulated (fully insured) plans to cover ABA, but if your employer self-funds its plan, it is exempt under ERISA. Many self-funded plans still cover ABA, so check your plan documents or call the number on your member card.

What happens at age 3 if my child still needs services?

Part C ends on the third birthday. Your Part C team will help you transition to the school district, which will evaluate for an IEP. If your child qualifies, they can receive special education services, including preschool and therapies, through the school system.
