Does Medicaid Cover ABA Therapy in Maryland? What Families Should Know

Introduction

If your child was just diagnosed with autism spectrum disorder (ASD) and you’re on Medicaid, the first question is usually the most practical one: will this actually be paid for? The short answer is yes. Maryland Medicaid covers medically necessary Applied Behavior Analysis (ABA) therapy for enrolled children under 21, and it has done so since January 2017. But “yes” doesn’t tell you much about how the process actually works, who manages it, or what to expect once you start.

This guide walks through what Maryland Medicaid coverage for ABA therapy really looks like: who qualifies, how authorization works, what’s included, and where families most often get confused. If you’re a parent trying to figure out next steps, an educator supporting a family through this process, or a fellow ABA professional who wants a plain-language explainer to hand to intake families, this is written for you.

How Maryland Medicaid Covers ABA Therapy

Maryland Medicaid delivers most services through a managed care program called HealthChoice. Almost every Medicaid-eligible child in the state is enrolled in HealthChoice, which means their coverage runs through a Managed Care Organization (MCO), a health plan either chosen by the family or assigned at enrollment.

Here’s the part that trips up a lot of families: ABA therapy is not managed by your MCO. Behavioral health services, including ABA, are “carved out” of HealthChoice and handled separately by a single statewide administrator. That means your child’s ABA authorization and claims go through one system, regardless of which MCO your child is assigned to.

Who Administers ABA Benefits: Carelon Behavioral Health

The entity responsible for that carve-out is Carelon Behavioral Health, which serves as Maryland’s Behavioral Health Administrative Services Organization (BHASO). Carelon replaced the previous administrator in a transition that took effect in 2025, and it now handles prior authorization, treatment plan review, and claims processing for ABA services across both HealthChoice managed care and fee-for-service Medicaid. In our experience helping families navigate this system, understanding that Carelon, not your MCO, is the point of contact for ABA saves a lot of wasted phone calls.

The legal foundation for coverage sits under the Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit, a federal Medicaid requirement that guarantees medically necessary services for children without arbitrary hour or dollar caps. That’s an important protection: coverage decisions are supposed to be based on what a child clinically needs, not a preset limit on sessions per month.

Eligibility Requirements for Medicaid ABA Coverage

Age Requirements

Maryland Medicaid covers ABA therapy for enrolled participants under the age of 21. There is no minimum age built into the policy itself, which is why early intervention ABA is such a common entry point for younger children who show early signs of autism.

Diagnosis Requirements

To access ABA benefits, a child needs a formal ASD diagnosis from a qualified health care professional (QHCP). 

Under Maryland’s program, that includes:

• A developmental pediatrician 
• A pediatric neurologist 
• A child psychiatrist 
• A clinical psychologist 
• A neuropsychologist 
• A pediatrician 
• A nurse practitioner

The diagnosis has to come from a comprehensive diagnostic evaluation using validated assessment tools, not just a brief office visit. This is one of the reasons diagnostic services matter so much as a starting point. Families sometimes assume any provider can write a referral, but the QHCP needs both the training and the documented evaluation process to satisfy Medicaid’s requirements.

What Services Are Included

Once a child is authorized, Maryland Medicaid’s ABA benefit typically covers the full clinical program rather than just direct therapy hours. In practice, that generally includes:

• Initial assessment by a Board Certified Behavior Analyst (BCBA) 
• Development of an individualized treatment plan with specific, measurable goals 
• Direct treatment sessions delivered by Registered Behavior Technicians (RBTs) 
• Ongoing BCBA supervision of the treatment plan 
• Parent and caregiver training, so families can reinforce strategies outside of sessions

That last point deserves emphasis. Maryland’s ABA regulations specifically require that a parent or caregiver be trained to reinforce ABA strategies at home. In our sessions, this is often where families see the most meaningful progress: not just the hours a technician spends with a child, but what happens in the hours between sessions once caregivers know what to reinforce and how.

Depending on a family’s needs and their provider’s service offerings, this care can be delivered through in-home ABA therapy, daycare-based ABA, weekend ABA, or early intervention programs for younger children. The setting matters less to Medicaid than the medical necessity documentation behind it, but it matters a great deal to the family living it day to day.

Medicaid ABA vs. the Autism Waiver: A Common Point of Confusion

One of the most persistent misunderstandings we hear from families is the belief that they need to get on the Maryland Autism Waiver waitlist before their child can start ABA therapy. That’s not accurate, and it’s worth clearing up directly.

Standard Medicaid, through the EPSDT benefit described above, is the correct and primary pathway to ABA therapy. It’s a federal entitlement, meaning eligible children have a legal right to receive it once medical necessity is established.

The Autism Waiver is a separate, supplemental Home and Community-Based Services program administered through Maryland’s education system. It’s designed for children with significant support needs whose care would otherwise require an institutional setting, and it includes services like intensive individual support, respite care, and environmental accessibility adaptations. It does not include ABA therapy, and its waitlist has historically run for years.

If someone tells a family they need to wait for the Autism Waiver before starting ABA, that advice is incorrect and can delay care that a child is already entitled to receive. These are two different programs solving two different problems.

How to Get Started

For a family navigating this for the first time, the process generally looks like this:

1. Get a formal ASD diagnosis from one of the qualified professionals listed above, based on a comprehensive diagnostic evaluation. 
2. Confirm active Medicaid enrollment and, if needed, connect with your assigned MCO to confirm your child’s eligibility status. 
3. Choose an ABA provider that is credentialed to bill Maryland Medicaid through Carelon. 
4. Have the provider submit a treatment plan for prior authorization, including assessment data and specific goals tied to medical necessity. 
5. Begin services once authorization is approved, with periodic reauthorization as treatment continues.

Prior Authorization Process

All ABA services in Maryland require prior authorization through Carelon before they begin. This means a provider can’t simply start seeing a child and bill Medicaid afterward. The provider’s clinical team documents baseline functioning, develops a treatment plan tied to specific goals, and submits that plan for review before treatment starts. Reauthorization typically happens on a periodic basis as the child progresses, which is why ongoing data collection is such a routine part of quality ABA care, not just a formality for insurance purposes.

What This Looks Like for Families

We’ve worked with families who came to us assuming, incorrectly, that Medicaid coverage would mean long delays or limited services. In one case, a family had been told by another provider that ABA wasn’t available until their child aged off an Autism Waiver waitlist. Once we walked through the difference between the waiver and standard Medicaid ABA coverage, and helped the family gather the diagnostic documentation needed for authorization, their child was able to start treatment planning within weeks rather than remaining on a multi-year waitlist. That gap between what families are told and what coverage actually allows is one of the most common obstacles we see, and it’s almost always solvable with the right information upfront.

Common Challenges and How to Navigate Them

A few issues tend to come up repeatedly:

Confusion about who to call. Because ABA is carved out of HealthChoice, calling your MCO first can lead to a runaround. Carelon, not the MCO, is the correct point of contact for ABA-specific questions.

Incomplete diagnostic documentation. Authorization can stall if the diagnosing provider didn’t use a comprehensive diagnostic evaluation or validated assessment tools. Confirming this upfront with your diagnosing provider can prevent delays later.

Assuming waitlists apply to standard coverage. As covered above, the Autism Waiver waitlist has nothing to do with standard Medicaid ABA access.

Coordination with school-based supports. For school-age children, ABA services delivered in a school setting must be clinically justified and individualized; a Registered Behavior Technician generally cannot function as a substitute for a 1:1 educational aide provided through an IEP. Families and school personnel sometimes need to clarify how ABA goals and IEP goals work together rather than in place of one another.

Conclusion

Maryland Medicaid does cover ABA therapy for medically necessary treatment through age 21, delivered through the EPSDT benefit and administered separately from HealthChoice by Carelon Behavioral Health. The path to coverage runs through a formal ASD diagnosis, provider-submitted treatment plans, and prior authorization, not through the Autism Waiver waitlist. For families who understand how the pieces fit together, Medicaid coverage for ABA in Maryland is more accessible than the process can initially appear.

If you’re trying to figure out where your family stands, whether that’s confirming Medicaid eligibility, understanding a denial, or simply getting a diagnosis referral started, talking it through with a provider who works inside this system daily can save weeks of back and forth.

Frequently Asked Questions

Does Maryland Medicaid cover ABA therapy for autistic children? 

Yes. Maryland Medicaid covers medically necessary ABA therapy for enrolled children under 21 through the EPSDT benefit, administered by Carelon Behavioral Health rather than through your assigned MCO.

Do I need to be on the Autism Waiver waitlist to get ABA therapy through Medicaid? 

No. Standard Medicaid coverage, not the Autism Waiver, is the correct pathway to ABA therapy. The Autism Waiver is a separate program that doesn’t include ABA services, and waiting for it can unnecessarily delay care your child is already entitled to.

What do I need to qualify for Medicaid-covered ABA therapy in Maryland? 

Your child needs active Medicaid enrollment and a formal ASD diagnosis from a qualified health care professional based on a comprehensive diagnostic evaluation. From there, a provider submits a treatment plan for prior authorization before services begin.
