In short: Maine offers two main Medicaid waivers that can cover autism services: the Section 21 Home and Community Based Waiver for adults with intellectual disabilities or autism, and the Section 29 Children's Home and Community Based Waiver for children under 21. These waivers can help pay for Applied Behavior Analysis (ABA) therapy, respite care, and other supports. Eligibility depends on income, disability status, and meeting an institutional level of care, and there is often a waiting list for services.

Key takeaways

  • Maine's Section 21 waiver covers adults (21+) with autism or intellectual disabilities, offering services like ABA therapy, day programs, and residential supports.
  • The Section 29 Children's Waiver serves children under 21 with autism or other developmental disabilities, funding ABA therapy, in-home supports, and respite care.
  • Both waivers require applicants to meet an institutional level of care and have financial eligibility through MaineCare (Maine's Medicaid program).
  • There is typically a waiting list for these waivers; applying early and staying in touch with the local office is crucial.

What Are Maine Medicaid Waivers for Autism Services?

Maine's Medicaid program, known as MaineCare, offers home and community-based services (HCBS) waivers that help people with autism and other developmental disabilities receive care in their own homes and communities rather than in institutions. These waivers are designed to fill gaps in traditional Medicaid coverage by funding a range of supports, including Applied Behavior Analysis (ABA) therapy, which is a widely recognized, evidence-based intervention for autism.

For families in Maine, understanding these waivers is key to accessing affordable autism services. The two main waivers relevant to autism are the Section 21 Waiver (for adults 21 and older) and the Section 29 Children's Waiver (for children under 21). Each has its own eligibility criteria, covered services, and application process.

Who Is Eligible for Maine Autism Waivers?

Eligibility for Maine's autism waivers involves meeting both clinical and financial requirements. Here's a breakdown:

Clinical Eligibility

  • Diagnosis: You or your child must have a diagnosis of autism spectrum disorder (ASD) or a related intellectual/developmental disability. A formal diagnosis from a qualified professional (e.g., developmental pediatrician, psychologist) is required.
  • Level of Care: You must meet the state's criteria for an institutional level of care, meaning the person's needs are significant enough that they would qualify for care in a nursing facility or intermediate care facility. This is determined through a standardized assessment.
  • Age: For the Section 29 Children's Waiver, the individual must be under 21. For Section 21, the person must be 21 or older.

Financial Eligibility

To receive waiver services, you must be enrolled in MaineCare or meet the income and asset limits for MaineCare. For children, the income limits are often higher (through the Katie Beckett option or other pathways). For adults, income and asset limits apply, but there are spend-down options. It's best to contact your local MaineCare office or a benefits counselor to check your specific situation.

What Services Do the Waivers Cover for Autism?

Both waivers cover a broad range of services tailored to individual needs. For autism, the most commonly used services include:

  • Applied Behavior Analysis (ABA) Therapy: This is a core service under both waivers. ABA therapy is provided by a Board Certified Behavior Analyst (BCBA) and can be delivered in the home, school, or community. It focuses on building communication, social, and daily living skills while reducing challenging behaviors.
  • Respite Care: Temporary relief for caregivers, allowing them time for rest or errands. This can be provided in or out of the home.
  • Personal Support Services: Help with daily activities like bathing, dressing, and meal preparation.
  • Day Programs: Structured activities and skill-building in a community setting.
  • Supported Employment: Job coaching and support for adults seeking or maintaining employment.
  • Behavioral Consultation: Guidance from a behavior specialist to develop and monitor behavior support plans.
  • Transportation: Non-emergency medical transportation to appointments.

It's important to note that services must be prior authorized by MaineCare and provided by a qualified, enrolled provider. For ABA therapy, the provider must be a BCBA or supervised by one.

How to Apply for a Maine Autism Waiver

Applying for a waiver can feel overwhelming, but breaking it down into steps helps. Here's a general process:

Step 1: Get a Diagnosis and Documentation

Gather all medical records showing the autism diagnosis, as well as any assessments that document the need for support. This includes reports from doctors, therapists, and school evaluations.

Step 2: Contact Your Local MaineCare Office

Reach out to the Maine Department of Health and Human Services (DHHS) office in your county. Ask about the waiver application process and request a screening to determine if you meet the level of care criteria. The DHHS website has a list of regional offices.

Step 3: Complete a Comprehensive Assessment

You will need a comprehensive assessment to document the individual's needs. This is often done by a case manager or a provider agency. The assessment will be used to create a Person-Centered Plan (PCP) that outlines the services needed.

Step 4: Apply for MaineCare (If Not Already Enrolled)

If you are not already on MaineCare, you'll need to apply for it. You can do this online through My Maine Connection or by paper application. Be prepared to provide proof of income, assets, and residency.

Step 5: Get on the Waiting List

Both waivers have limited slots and often have waiting lists. Once your application is approved for eligibility, you will be placed on the waiting list. The wait can be months to years, depending on the waiver and available funding. Stay in touch with your case manager to update any changes in your situation.

Step 6: Choose a Provider

Once a slot opens, you can choose a provider for the services on your plan. For ABA therapy, you'll want to find a BCBA-led provider who accepts MaineCare waiver funding. A free service like ABA Therapy Now can help match you with vetted providers in your area.

Costs and Insurance Coverage for ABA Therapy Under Maine Waivers

When you are enrolled in a MaineCare waiver, the cost of covered services, including ABA therapy, is paid for by MaineCare. There are no out-of-pocket costs for the services themselves, though there may be small co-pays for some medical services under MaineCare (these are typically very low).

If you have private insurance in addition to MaineCare, your insurance may also cover ABA therapy, and the waiver can fill in gaps. It's important to coordinate benefits to maximize coverage. Many ABA providers in Maine accept both MaineCare and private insurance.

For families not yet on a waiver, private insurance plans in Maine are required to cover autism services, including ABA, under the state's autism insurance mandate. However, waivers often provide more comprehensive coverage, including respite and day programs, which private insurance may not cover.

Common Mistakes to Avoid When Applying for Maine Autism Waivers

  • Waiting too long to apply: The waiting lists can be long, so apply as soon as you have a diagnosis, even if you're not sure you'll need services right away.
  • Not having a complete diagnosis: Ensure the diagnosis is from a qualified professional and includes the specific criteria needed for the waiver.
  • Missing paperwork: Keep copies of all documents and follow up with the DHHS office to confirm they received everything.
  • Assuming you don't qualify: Many families think they make too much money, but there are pathways like the Katie Beckett option for children that disregard parental income. Always check with a benefits counselor.
  • Not updating your case manager: If your child's needs change or you move, inform your case manager immediately to avoid delays.
