Does Medicaid Cover ABA Therapy? A Parent's Guide

When my daughter needed ABA therapy, one of my first steps was figuring out whether my insurance would pay for it. It felt like just another hurdle to an already complicated process.

Medicaid can cover medically necessary ABA therapy for eligible children with autism. Federal Medicaid requirements provide important protections for children under 21. However, how ABA coverage works depends on your state.

Your state Medicaid program may have its own requirements for autism diagnosis, referral, treatment plan, prior authorization, provider qualifications, and the number of therapy hours it will approve.

Here's what parents should know about Medicaid coverage for ABA therapy. You'll also find information on EPSDT, how approval works and what you can do if your child's ABA therapy is denied.

Key Takeaways

• Medicaid can cover medically necessary ABA therapy for eligible children with autism.
• Federal EPSDT requirements provide Medicaid-enrolled children under age 21 with access to medically necessary services covered under federal Medicaid law.
• Each state administers its own Medicaid program, so ABA requirements and authorization processes can differ.
• Your child may need an autism diagnosis, referral or prescription, treatment plan, and prior authorization before ABA begins.
• If Medicaid denies ABA therapy, you have the right to find out why and may have options to appeal the decision.
• Families should look for ABA providers that participate in their specific state Medicaid program. If your child has Medicaid and you want to start ABA therapy, you can get started with Alpaca Health.

Does Medicaid cover ABA therapy?

Yes. Medicaid can cover ABA therapy when it's considered medically necessary for an eligible child with autism.

Applied Behavior Analysis (ABA) is a type of behavior therapy. Its goal is to help autistic children develop skills and behaviors that affect daily life. Care is individualized to your child's needs. That means ABA can focus on areas such as communication, social interaction, self-care, learning, and safety.

For children enrolled in Medicaid, federal requirements known as Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) play a key role in access to medically necessary care.

Medicaid isn't one identical health plan used across the country. Each state operates its own Medicaid program within federal requirements. That means the process you follow to get ABA therapy approved in Colorado may look different from the process another parent follows in Texas or California.

Coverage also doesn't mean every ABA service or requested number of hours will automatically be approved, and not every therapy provider participates in Medicaid.Your child's state Medicaid program may require documentation showing that ABA is medically necessary, and providers must meet established requirements before treatment begins.

If your child has Medicaid and you're trying to start ABA therapy, Alpaca Health accepts Medicaid in the states it serves and handles the prior authorization for you.

What EPSDT means for children under 21

EPSDT is a federal Medicaid benefit for children and adolescents under the age of 21. It requires state Medicaid programs to provide medically necessary services within Medicaid- covered benefit categories when needed to treat a physical or mental health condition.

This requirement applies even when a particular service isn't otherwise included in a state's Medicaid plan.

EPSDT can be especially important for an autistic child. It gives families a federal framework for accessing medically necessary treatment. However, EPSDT doesn't specifically require states to provide ABA to every autistic child. Your state's Medicaid program determines whether requested services are medically necessary based on your child's individual needs.

Even if you're approved for Medicaid, it doesn't automatically mean ABA will be approved. Your child must still meet the state's coverage and medical-necessity requirements.

Why coverage still looks different in every state

Each state operates its own program within federal requirements. This is why another parent's experience getting ABA covered may look completely different from yours.

States can establish their own processes for determining medical necessity and administering autism services. Depending on where you live, you may find differences such as:

• What documentation is required before ABA begins
• Who can diagnose your child or make a referral
• Whether prior authorization is required
• What must be included in your child's treatment plan
• Which ABA providers can enroll with Medicaid
• How frequently your child's treatment must be reviewed
• How Medicaid determines the amount or duration of therapy it will authorize

You may also be enrolled in a Medicaid managed care plan instead of receiving services directly through the state's Medicaid program. In these cases, you'll need to follow your child-specific plan's requirements.

That's why it's helpful to start with your state Medicaid program and your child's health plan rather than relying on another family's experience.

Does Medicare pay for ABA therapy?

Medicare and Medicaid operate as two separate programs. The distinction matters when you're researching ABA coverage.

Medicaid is the program most parents encounter when looking for ABA coverage for a child. Medicare primarily provides health insurance for people aged 65 and older, although some younger people may qualify because of a disability or certain health conditions.

Medicare doesn't have the same EPSDT benefit that Medicaid provides for children under 21. Autistic adults covered by Medicare may find that their coverage for behavioral health services depends on Medicare's benefit and medical necessity requirements.

If someone has both Medicare and Medicaid, the two programs often coordinate coverage. In most situations, Medicare pays first for the Medicare-covered service, and Medicaid may help with certain remaining costs or Medicaid-covered services.

If you're looking specifically for ABA therapy for an adult with Medicare, check the person's individual coverage rather than assuming the pediatric Medicaid rules also apply.

What does Medicaid require to approve ABA therapy?

With Medicaid, your child may not be able to start ABA therapy right away. Your state Medicaid program or managed care plan may require documentation before it authorizes treatment.

The exact process varies by state and health plan. Depending on your state and health plan, you may be asked to provide documentation of your child’s diagnosis, referral or prescription, along with a treatment plan that explains why the requested services are medically necessary.

A qualifying autism diagnosis

Many state Medicaid ABA programs look for medical documentation of an autism spectrum diagnosis. Pay attention to who is allowed to make the diagnosis for Medicaid purposes. Depending on your state, Medicaid may require an evaluation specifically from a physician, psychologist or another qualified healthcare professional.

If your child already has an autism diagnosis, it doesn't mean you'll need to start the diagnostic process over. Ask your Medicaid plan or ABA provider whether the evaluation you already have meets your state's requirements.

“If you can, send the full evaluation report rather than only the one-page diagnosis letter,” says Maria Orzechowski, PsyD, who works with neurodiverse children and their families. “Reviewers usually want the details about how your child is doing day to day, and that’s all in the full report.”

A prescription or referral

Your plan may also ask for a referral, prescription or recommendation for ABA therapy from an approved healthcare professional. The specific requirement varies.

Before scheduling another appointment, ask the ABA provider or your child's Medicaid plan exactly what documentation is required and who is allowed to complete it.

Prior authorization and the treatment plan

You may hear the term ‘prior authorization’. This means Medicaid or your child's managed care plan will review the requested ABA services before agreeing to cover them.

Your ABA provider will typically play an important role in this process. The treatment plan may describe your child's current needs, treatment goals, recommended services, and why the requested treatment is medically necessary.

Medicaid can use prior authorization and other utilization controls, but decisions for children covered by EPSDT should consider your child's individual needs. A request shouldn't be denied simply because another autistic child receives fewer services.

Always keep copies of your child's paperwork, including their evaluation, treatment plan, authorization request, and any letters you received from Medicaid. Having everything together can make it much easier to understand what was approved and what to do if something is denied.

“Keep a folder, real or digital (or both!), and put every report in it the day you get it,” Maria adds. “It’ll help you big time later on. I can’t tell you how often a family needs something from two years ago and it’s buried in an email somewhere. Rarely, families can even end up having to redo services or testing because the paperwork got lost.”

How many ABA hours will Medicaid approve?

There isn't one set number of ABA hours that Medicaid approves for every autistic child.

The amount of therapy your child needs should be based on their individual needs rather than an autism diagnosis alone. Your child's ABA provider may recommend a certain number of hours based on their expert assessment and treatment goals in the areas where your child needs support.

Medicaid or your child's managed care plan then reviews the request under its medical necessity and authorization requirements.

Your child may be approved for fewer hours than the provider originally requested. The authorization may also cover a specific period of time, with another review required before services continue.

If Medicaid approves fewer hours than your child's provider recommends, ask for the reason in writing. You may then talk with the provider about whether additional clinical information is needed or whether you have the option to appeal the decision.

Turn these ideas into a plan built for your child.

Activities at home are a great start, and a Board Certified Behavior Analyst can shape them into a program around your child's real goals. Alpaca Health matches you with one, often within days.

Finding an ABA provider that accepts Medicaid

If you're searching for ABA therapy near you that accepts Medicaid, make sure the provider participates in your child's specific Medicaid plan.

Start by checking your child's Medicaid plan provider directory or calling the member services number on the insurance card. You can also contact ABA providers directly and ask:

• Do you accept my child's specific Medicaid plan?
• Are you currently accepting new Medicaid patients?
• Do you handle prior authorization?
• What evaluations or documents do you need before we start?
• Is there a waitlist?
• Do you provide ABA in a clinic, at home or in other settings?
• What happens if Medicaid approves fewer hours than the treatment plan recommends?

Make sure to provide details about your child's Medicaid plan. A provider may accept Medicaid but not participate with every Medicaid managed care plan in your state.

Once you find a provider, ask what they handle for you and what you'll need to do yourself.

What to do when Medicaid denies ABA therapy

Receiving a Medicaid denial can feel defeating. If your child's provider believes ABA therapy is medically necessary, a denial doesn't always mean you've reached the end of the process.

Your first step is to understand exactly what Medicaid denied and why. Then you can determine whether information is missing, additional documentation may help, or an appeal may be appropriate.

Reading the denial letter

You should receive a copy of the denial letter. Look for the specific reason for the denial. For example, the plan may determine that the requested service doesn't meet its medical necessity criteria or that required documentation wasn't submitted. A denial may also involve the requested number of ABA hours rather than the ABA therapy altogether.

The notice will also include information about your appeal rights and the deadline to act.

Don't throw away the letter even if your ABA provider is handling the authorization. Keep it with your child's evaluation, treatment plan, and other Medicaid paperwork.

Filing an internal appeal

Managed care plans often allow you to appeal the denial through the health plan. Talk with your child's ABA provider before filing. The provider may be able to explain the clinical reasoning behind the requested treatment and provide records or additional documentation that supports medical necessity.

“Don’t forget that your child’s evaluator can be part of the team here, too!” Maria explains. “Sometimes a denial comes down to a report that didn’t spell out what your child’s needs look like day to day. It’s completely reasonable to call and ask whether anything can be clarified.”

Follow the instructions on your child's denial notice carefully. Appeal procedures and deadlines may vary, so use the information provided by your child's plan rather than assuming the process is the same in every state.

Requesting a fair hearing

Families may also have the right to request a state fair hearing to challenge certain Medicaid decisions.

A fair hearing gives you an opportunity to have the decision reviewed through the state Medicaid hearing process. You may need to complete a managed care appeal before requesting a fair hearing.

Again, watch your deadlines. Your denial notice should explain your hearing rights and how to make a request.

If you're unsure what the denial means, ask your child's Medicaid plan or ABA provider to walk you through it. Understanding whether the issue involves eligibility, authorization, documentation, medical necessity, or the amount of therapy requested can help you decide what to do next.

When your child has both Medicaid and private insurance

Your child may be eligible for Medicaid and private health insurance at the same time.

When more than one health plan covers your child, coordination of benefits determines which insurance is responsible for paying first. Typically, other available insurance pays before Medicaid.

Having two health plans can make ABA billing even more complicated. Your private insurance and Medicaid may have different provider networks, prior authorization requirements and coverage rules.

Before starting ABA, tell the provider about every insurance plan your child has. You'll also want to ask whether the provider participates with both plans and how they handle coordination of benefits.

You may also want to keep both insurance companies updated about your child's other coverage. Giving the provider accurate insurance information from the beginning can help prevent billing and authorization problems later.

Medicaid ABA coverage state by state

Each state may administer Medicaid coverage for ABA differently.

Federal EPSDT requirements protect access to medically necessary, Medicaid-covered services for eligible children under age of 21. This includes services used to treat autism. However, each state Medicaid program determines medical necessity and establishes its own process for providing and authorizing autism services.

ABA therapy requirements vary depending on where you live. If you're trying to find out whether your child's Medicaid plan covers ABA, start with your state's Medicaid website. Look specifically for information about autism services, applied behavior analysis, or behavioral health treatments.

If your child is enrolled in a Medicaid managed care plan, check that plan's requirements too. You can also ask an ABA provider that accepts your child's Medicaid plan to explain what documentation is required in your state.

Frequently asked questions about Medicaid and ABA therapy

Does Medicaid cover ABA therapy in every state?

Medicaid may cover medically necessary services used to treat autism for eligible children under the age of 21. However, ABA therapy isn't administered the same way in every state. Each state's Medicaid program determines medical necessity and establishes requirements for autism services to be authorized and delivered.

Check your state Medicaid program and your child's specific health plan for current ABA coverage and authorization requirements.

Is ABA therapy covered by Medicare for adults?

Medicare doesn't have the same EPSDT requirements that Medicaid has for children under the age of 21. An autistic adult with Medicare should check their individual coverage for behavioral health services and ask whether the recommended treatment meets Medicare coverage requirements. If someone has both Medicare and Medicaid, Medicaid may help cover certain services or costs that Medicare doesn't cover.

How do I find ABA therapy that accepts Medicaid?

Start with your state Medicaid provider directory or your child's Medicaid managed care plan provider directory. You may also contact ABA providers directly and ask whether they accept your child's specific plan. Before choosing a provider, ask whether they're accepting new Medicaid patients, whether there's a waitlist and whether they help families complete the prior authorization process.

What do I do if Medicaid denies ABA therapy?

If Medicaid denies ABA therapy, you'll receive a denial notice. Read it carefully to find out why the request was denied and what appeal options are available. Then speak with your child's ABA provider about whether additional clinical information could support the request. Follow the appeal instructions and deadlines listed in the notice.

Depending on your child's Medicaid coverage and state, you may have options that include an appeal to the health plan and a state fair hearing.

If you're having trouble getting your child's ABA therapy started, Alpaca Health can help by checking your child's Medicaid benefits and matching you with an in-network BCBA.
