What Is the MaineCare ABA Therapy Age Limit?

MaineCare covers ABA therapy for children and young adults under the age of 21 who have a medical diagnosis of autism spectrum disorder. There is no strict lower age limit, but services typically begin after age 2, when a diagnosis can be reliably made. The age limit of 21 aligns with federal Medicaid Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) requirements, which mandate coverage for medically necessary services for individuals under 21.

Eligibility Requirements

To qualify for MaineCare-covered ABA therapy, a child must:

  • Have a medical diagnosis of autism spectrum disorder from a qualified professional (e.g., developmental pediatrician, child psychiatrist, or psychologist).
  • Be under age 21 at the time services begin.
  • Have a referral or prescription for ABA therapy from a doctor or other licensed provider.
  • Meet medical necessity criteria, which typically includes demonstrating that ABA is needed to address specific behavioral or developmental challenges.

What About Children Over 21?

Once a young adult turns 21, MaineCare generally stops covering ABA therapy under the EPSDT benefit. However, some individuals may qualify for other MaineCare programs or waivers that cover behavioral health services. Families should contact MaineCare or a local case manager to explore options for continued support after age 21.

What ABA Services Does MaineCare Cover?

MaineCare covers a range of ABA services when deemed medically necessary. These include:

  • Assessment and evaluation: A board-certified behavior analyst (BCBA) conducts a functional behavior assessment to identify target behaviors and develop a treatment plan.
  • Treatment planning: The BCBA creates an individualized plan with specific goals and interventions.
  • Direct therapy: Registered behavior technicians (RBTs) provide one-on-one therapy under BCBA supervision, focusing on skill building and behavior reduction.
  • Parent training: Caregivers receive training to support their child's progress at home and in the community.
  • Supervision and monitoring: The BCBA regularly reviews progress and adjusts the plan as needed.

How Many Hours Are Covered?

MaineCare does not set a fixed number of hours for ABA therapy. Instead, the number of hours is determined by medical necessity and outlined in the treatment plan. Typical plans range from 10 to 40 hours per week, depending on the child's needs. The BCBA works with the family to recommend an appropriate intensity.

How to Access MaineCare-Covered ABA Therapy

Getting started with ABA therapy through MaineCare involves several steps:

  1. Obtain a diagnosis: If your child does not already have an autism diagnosis, seek an evaluation from a qualified professional. Maine's Child Development Services (CDS) or Early Intervention programs can help with evaluations for children under 3.
  2. Get a referral: Ask your child's doctor or specialist to write a prescription or referral for ABA therapy. This document should state the diagnosis and medical necessity.
  3. Find a provider: Look for a MaineCare-approved ABA provider that employs BCBAs and RBTs. ABA Therapy Now is a free service that can match your family with vetted, BCBA-led providers in Maine.
  4. Complete an assessment: The provider will conduct an initial assessment to develop a treatment plan.
  5. Submit for authorization: The provider will submit the treatment plan to MaineCare for prior authorization. Once approved, therapy can begin.
  6. Common Mistakes to Avoid

    • Waiting too long: Early intervention is key. Don't delay seeking a diagnosis or referral, even if your child is very young.
    • Assuming age limits are rigid: While the age limit is 21, some children may qualify for exceptions or waivers. Always ask about options.
    • Not verifying provider credentials: Ensure the provider is MaineCare-approved and employs BCBAs. ABA Therapy Now can help verify this.
    • Ignoring parent training: Parent involvement is crucial for success. Take advantage of training opportunities offered by the provider.

    Costs and Insurance Considerations

    For families enrolled in MaineCare, ABA therapy is covered at no cost. There are no copays, deductibles, or coinsurance for covered services. However, families must ensure their provider is in-network with MaineCare. If a provider is out-of-network, services may not be covered, or families may face higher costs.

    Private Insurance and MaineCare

    Some families have both MaineCare and private insurance. In such cases, MaineCare is typically the secondary payer. The provider will bill the primary insurance first, and MaineCare may cover remaining costs. It's important to coordinate benefits with both insurers to avoid unexpected bills.

    What to Expect During ABA Therapy

    ABA therapy is highly individualized. Sessions may take place at home, in a clinic, or in community settings. The BCBA and RBTs work on skills like communication, social interaction, self-care, and reducing challenging behaviors. Progress is tracked regularly, and the treatment plan is adjusted as the child grows.

    Tips for Success

    • Be consistent: Attend sessions regularly and follow through with strategies at home.
    • Communicate openly: Share concerns and successes with the BCBA to refine the plan.
    • Celebrate small wins: Progress may be gradual, but every step forward matters.
    • Seek support: Connect with other families through local autism support groups or online communities.
