Understanding MaineCare ABA Therapy Coverage

If your child has been diagnosed with autism spectrum disorder (ASD) and you are a Maine resident, MaineCare (Maine's Medicaid program) can be a vital resource for accessing Applied Behavior Analysis (ABA) therapy. ABA is an evidence-based therapy that focuses on improving communication, social skills, and adaptive behaviors while reducing challenging behaviors. MaineCare covers ABA for eligible children under the age of 21 as part of the federal Early and Periodic Screening, Diagnostic and Treatment (EPSDT) benefit, which mandates that states provide medically necessary services to children enrolled in Medicaid.

This article walks you through everything you need to know about MaineCare ABA coverage - from eligibility and covered services to the authorization process and practical steps for getting started. Along the way, we'll explain how ABA Therapy Now, a free matching service, can connect you with BCBA-led providers who accept MaineCare, making the search less overwhelming.

Who Is Eligible for MaineCare ABA Therapy?

Age and Diagnosis Requirements

Eligibility for MaineCare ABA coverage requires that:

  • The child is under 21 years old. (Note: MaineCare coverage for adults with autism may differ, but ABA is primarily covered for children through EPSDT.)
  • The child has a formal diagnosis of autism spectrum disorder (ASD) from a qualified professional, such as a developmental pediatrician, child psychiatrist, or psychologist.
  • A physician or other licensed practitioner prescribes ABA therapy as medically necessary.

MaineCare Enrollment

Your child must be enrolled in MaineCare or a MaineCare managed care plan (such as MaineCare's Section 1115 waiver or a managed care organization like Anthem or MaineCare Choice). If you're not sure about your child's eligibility, you can apply through the Maine Department of Health and Human Services (DHHS) online or at your local DHHS office.

What ABA Services Does MaineCare Cover?

Covered Services Under EPSDT

MaineCare covers a range of ABA services, including but not limited to:

  • Direct one-on-one therapy with a registered behavior technician (RBT) under BCBA supervision.
  • BCBA supervision and parent training sessions.
  • Treatment plan reviews and progress monitoring.

Services can be delivered in various settings: in-home, in a clinic, at school (with coordination with the school district), or in community settings. Coverage amounts are determined based on medical necessity and are not subject to arbitrary session limits, although prior authorization is required.

How to Get ABA Therapy Through MaineCare: Step-by-Step

Getting started with ABA therapy through MaineCare involves several steps. Here's what you can expect:

1. Obtain a Diagnostic Evaluation

Your child needs a clear ASD diagnosis. If you don't have one yet, ask your pediatrician for a referral to a specialist. Some organizations in Maine, such as the Maine Medical Center's Developmental-Behavioral Pediatrics program or the University of Maine's Autism Center, offer evaluations. Wait times can be long, so it's wise to get on a waitlist early.

2. Get a Prescription or Referral

Once you have the diagnosis, ask the diagnosing provider or your child's primary care provider to write a prescription or referral for ABA therapy. The prescription should state the medical necessity and recommended intensity (e.g., number of hours per week).

3. Find a MaineCare-Approved ABA Provider

Your next step is to find a Board Certified Behavior Analyst (BCBA) who accepts MaineCare. This can be challenging because provider lists from MaineCare are often outdated. This is where ABA Therapy Now comes in. We are a free matching service that connects you with vetted, BCBA-led providers who accept MaineCare in your area. Simply fill out a short form, and we'll share your information with participating providers who meet your needs.

4. Submit for Prior Authorization

The ABA provider will submit a request for prior authorization to MaineCare (or your managed care plan). The request includes the evaluation, treatment plan, and supervision information. Approval can take a few weeks. Once approved, therapy can begin.

5. Begin Therapy and Monitor Progress

After authorization, therapy sessions start. The BCBA will supervise RBTs and adjust the plan as needed. MaineCare requires ongoing documentation, and the provider will submit regular progress reports to maintain authorization.

Common Mistakes to Avoid When Using MaineCare for ABA

Families often encounter pitfalls. Here are a few to avoid:

  • Waiting too long for a diagnosis. Start the evaluation process as early as possible, even if you're unsure about ABA. Early intervention is key.
  • Not verifying provider acceptance of MaineCare. Some clinics may advertise that they accept MaineCare but have limited slots. Always confirm before starting the paperwork.
  • Ignoring managed care requirements. If your child is in a MaineCare managed care plan (like Anthem or MaineCare Choice), you may need to follow that plan's specific authorization procedures.
  • Assuming coverage extends after age 21. Plan for transition services if your child is approaching 21; MaineCare may offer alternative supports for adults.

It's best to check with MaineCare or your managed care plan for adult behavioral health options.

Does MaineCare cover in-home ABA therapy?

Yes, MaineCare covers ABA therapy in multiple settings, including in-home, clinic-based, school (with coordination), and community settings. The setting depends on the child's needs and the provider's availability.

Is prior authorization required for ABA therapy under MaineCare?

Yes, MaineCare requires prior authorization for ABA services. The provider submits a request with a diagnostic evaluation and treatment plan. Authorization can take several weeks, so plan ahead.

What if my child's ABA provider doesn't accept MaineCare?

If a provider does not accept MaineCare, you may need to find another provider who does. ABA Therapy Now can help by matching you with providers who participate with MaineCare. You can also ask the provider if they are willing to apply to become a MaineCare provider.

Are ABA therapy hours limited under MaineCare?

MaineCare does not impose arbitrary session limits. Hours are determined by medical necessity as documented in the treatment plan.
