Massachusetts Autism Waiver Program: What Families Need to Know

In short: Massachusetts offers the Children's Autism Waiver (CAW), a program that pays for ABA therapy and other supports for eligible children up to age 9. Families do not pay out-of-pocket; MassHealth covers the services. To get started, families must apply through MassHealth and then find a qualified BCBA provider. ABA Therapy Now helps connect families with vetted, BCBA-led providers that accept the waiver.
Key takeaways
- The Massachusetts Children's Autism Waiver (CAW) covers ABA therapy for children with autism up to age 9, with no cost to families.
- Eligibility requires a medical diagnosis of autism and enrollment in MassHealth (Massachusetts Medicaid).
- Services include ABA, parent training, social skills groups, and behavioral consultation.
- Applications are managed through MassHealth; families may need a doctor's referral and evaluation.
What Is the Massachusetts Autism Waiver?
The Massachusetts Autism Waiver, formally called the MassHealth Children's Autism Waiver (CAW), is a program that provides home- and community-based services for children with autism spectrum disorder (ASD). This waiver allows families to access applied behavior analysis (ABA) therapy, parent training, and other supports without depleting their own finances. It is funded by MassHealth (Massachusetts' Medicaid program) and aims to help children develop communication, social, and daily living skills.
By covering ABA therapy - the gold-standard, evidence-based intervention for autism - the waiver ensures that children receive care in their homes, schools, or community settings. The program is designed for children up to age 9, after which families may transition to other services. Importantly, the waiver is free for eligible families; you won't pay co-pays or deductibles for covered services.

Who Is Eligible for the Children's Autism Waiver?
Age and Diagnosis Requirements
To qualify, a child must:
- Be between 0 and 9 years old (some sources say up to age 9, but check the current age limit with MassHealth).
- Have a medical diagnosis of autism spectrum disorder from a qualified professional (e.g., developmental pediatrician, psychologist).
- Be enrolled in MassHealth (standard MassHealth or a MassHealth managed care plan).
Level of Need
The child must require a level of care typically provided in a nursing facility or hospital, meaning the waiver is for children with significant functional limitations. A clinical assessment will determine if the child meets the criteria for institutional level of care. However, the waiver allows them to stay at home with community-based supports.
Residency and Insurance
The child must be a Massachusetts resident. If the family has private insurance, the waiver may be the payer of last resort; MassHealth may coordinate with private plans. In many cases, the waiver covers services not fully covered by private insurance.
What Services Does the Waiver Cover?
The CAW covers a range of services tailored to each child's needs. Common covered services include:
- Applied Behavior Analysis (ABA) therapy - one-on-one behavioral intervention provided by a Board Certified Behavior Analyst (BCBA) and trained technicians.
- Parent training and caregiver support - teaching families strategies to reinforce positive behaviors at home.
- Social skills groups - structured opportunities to practice peer interaction.
- Behavioral consultation - assessment and planning by a BCBA.
- Case management - coordinating care across providers.
- Respite services - temporary relief for caregivers (may be limited).
Services are typically provided in the child's natural environment: home, daycare, or community settings. The number of hours per week varies based on the treatment plan and medical necessity.

How to Apply for the Massachusetts Autism Waiver
Step 1: Ensure Your Child Has a Diagnosis and MassHealth Enrollment
If your child already has a diagnosis and MassHealth coverage, skip to the next step. If not, start by seeing a doctor for an evaluation. For children under 3, Massachusetts Early Intervention (EI) can help with evaluations and referrals. After diagnosis, apply for MassHealth through the Health Connector or your local MassHealth office.
Step 2: Request a Clinical Evaluation for Waiver Eligibility
Contact MassHealth or your child's managed care plan to request an assessment for the Children's Autism Waiver. A qualified clinician will evaluate whether your child meets the institutional level of care criteria. The state has a specific application form and process; you may need a physician's statement.
Step 3: Get Approved and Choose a Provider
Once approved, you'll receive a service plan. You then need to find a BCBA-led provider who accepts the CAW. This is where ABA Therapy Now can help. We are a free matching service that connects families with vetted, BCBA-led therapy providers who are experienced with MassHealth and the waiver. We'll ask about your child's needs and your location to recommend providers with availability.
Step 4: Start Services
After selecting a provider, they will create a detailed treatment plan and begin therapy. Regular progress reports are shared with MassHealth to continue authorization.
Costs and Insurance Coverage
The waiver covers nearly all costs for eligible services. Families do not pay premiums, co-pays, or deductibles for CAW services. However, if the child has private insurance, the waiver may require coordination; the private plan might cover some services first, with the waiver picking up the rest. MassHealth will work with your family to ensure no out-of-pocket costs.
It's important to note that the waiver only covers children up to age 9. After that, families may explore other MassHealth benefits or apply for the Adult Autism Waiver (if applicable). Some children transition to school-based services.

Common Mistakes to Avoid When Applying
- Delaying the application: The waiver has limited slots and a waiting list. Apply as soon as your child is diagnosed and on MassHealth.
- Not having a complete diagnosis: Ensure your child's medical records include a clear autism diagnosis from an accepted professional.
- Assuming the waiver covers everything: Some therapies (e.g., speech, occupational) may be covered under standard MassHealth, not the waiver. Check your plan.
- Ignoring the age cap: If your child is about to turn 9, act quickly. The waiver may not cover services after that age.
- Choosing a provider without checking fit: Find a provider who specializes in your child's needs (e.g., verbal behavior, early intervention). Our free matching service helps ensure a good match.
