Medicaid ABA Coverage in Maryland
Find out if Maryland Medicaid covers ABA, who qualifies, and how to get started with therapy.
What Maryland Medicaid Covers
Maryland's Medicaid program, known as Maryland Medical Assistance or HealthChoice, covers medically necessary applied behavior analysis (ABA) for enrollees under 21. This coverage comes through the federal Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit, which requires states to cover any medically necessary service that can correct or improve a condition.
In practice, that means your child can get ABA therapy if a doctor or qualified professional says it's needed. Coverage includes assessment, treatment planning, and ongoing therapy sessions. There is no set dollar cap or hour limit written into state law for ABA under Medicaid, but your specific plan may have limits. Ask your Medicaid plan directly: "What are the authorized hours or visits for ABA per authorization period?"
Who Qualifies for ABA
To qualify, your child must be under 21 and enrolled in Maryland Medicaid. You'll need a formal diagnosis of autism spectrum disorder from a qualified professional, such as a developmental pediatrician, child psychologist, or psychiatrist. The diagnosis must be current and documented in your child's medical record.
You'll also need a treatment plan. This plan, usually written by a Board Certified Behavior Analyst (BCBA), outlines the specific goals and interventions. The plan must show that ABA is medically necessary, meaning it addresses a specific deficit or behavior that affects your child's daily functioning. Without a diagnosis and a treatment plan, Medicaid won't approve coverage.
How Prior Authorization Works
Before ABA can start, your Medicaid managed care plan must approve it. This is called prior authorization. The process starts when your child's provider (like a pediatrician or specialist) submits a request to your plan, along with the diagnosis and treatment plan.
Your plan reviews the request to make sure it meets medical necessity criteria. Approval can take a few weeks, so plan ahead. If denied, you have the right to appeal. Your plan's member services line can walk you through the appeal steps. Keep copies of all paperwork, including the diagnosis, treatment plan, and any denial letters.
- Check your member card for your plan's name and member services phone number.
- Ask your provider to submit the prior authorization request as soon as possible.
- Follow up with your plan weekly until you get a decision.
When a Provider's Panel Is Closed
Many ABA agencies in Maryland have limited Medicaid slots. If an agency says their panel is closed, ask to be put on a waitlist. Also ask if they have a satellite location or a sister clinic with openings.
You can also contact your Medicaid plan's member services and ask for a list of in-network ABA providers. Sometimes the plan can help you find an agency that has capacity. If you're stuck, consider expanding your search to neighboring counties. Our directory lists ABA agencies across the counties we cover, so there are options even if your first choice is full.
What About Employer Plans
If your child is on your employer's health insurance instead of Medicaid, the rules differ. Maryland has an autism insurance mandate, but it only applies to fully insured plans. Self-funded employer plans are governed by federal law (ERISA) and are not required to follow state mandates, though many cover ABA anyway.
Check your plan documents or call the number on your insurance card. Ask: "Is our plan fully insured or self-funded? Does it cover ABA therapy for autism?" If you're on a Marketplace plan, coverage varies by plan, so verify directly with the insurer.
