Maryland law requires many health plans to cover habilitative services, which include ABA, for children. Coverage details, prior authorization, and cost sharing vary by plan, so confirm your specific policy.
Maryland Medicaid
Maryland Medicaid covers medically necessary ABA for members under age 21 through its EPSDT benefit, administered by Carelon Behavioral Health Maryland. Prior authorization is required.
DDA Autism Waiver
For eligible children, Maryland's Autism Waiver funds additional home and community supports beyond clinical therapy. There is a waitlist and a registry to join.
Does Maryland require insurance to cover ABA?
Maryland requires many health plans to cover habilitative services for children, and these services include ABA. The details below come directly from Maryland state sources. Coverage, age limits, and authorization rules can change, so always verify with the official source and your own plan.
Commercial insurance and habilitative services
Maryland's habilitative services mandate (Md. Insurance Article §15-835) requires carriers (insurers, nonprofit health service plans, and HMOs) to cover habilitative services for children, which include treatment for autism such as ABA. Coverage runs at least until the end of the month in which the child turns 19, and ABA may not be denied on the grounds that it is experimental or investigational. The exact scope, cost sharing, and authorization steps depend on your plan and policy type.
Maryland Medicaid (Medical Assistance)
Per the Maryland Department of Health, "Medicaid covers medically necessary Applied Behavior Analysis (ABA) therapy services for members under the age of 21." ABA is provided through the EPSDT benefit, and Carelon Behavioral Health Maryland administers the program. All ABA services require prior authorization.

Maryland has held its Medicaid ABA rates steady
In 2025 and 2026, several states cut Medicaid reimbursement for ABA, including Texas, North Carolina, Nebraska, Indiana, and Colorado. Maryland has not joined that cut wave, so provider participation here has stayed comparatively stable. Maryland routes Medicaid ABA authorizations and claims through a single vendor, Carelon Behavioral Health, which has tightened some service-combination rules and increased provider audits, so it is still worth confirming that a provider is in-network and actively accepting Maryland Medicaid.
DDA Autism Waiver
Maryland's Autism Waiver serves children from age 1 up to the end of the school year when they turn 21. Eligibility requires an autism spectrum disorder diagnosis, an ICF/IID level of care, an IFSP or IEP with at least 15 hours per week of special education and related services, and meeting financial criteria. Covered services include respite care, family consultation, intensive individual support services, environmental accessibility adaptations, and adult life planning. The Waiver is a limited-slot program with a long waitlist: as of 2026, roughly 6,200 people are on Maryland's autism and developmental-disability waiting lists, and families can wait years for a slot. Because of that, the Waiver is best treated as a supplement to clinical ABA (which is covered through Medicaid EPSDT or commercial insurance), not the way to start therapy. Call the Autism Waiver registry at 866-417-3480 to get on the list, and do it as early as possible.
Before you rely on coverage

How to choose an ABA provider in Maryland
The right ABA center depends on your child's age, your schedule, and your insurance. Use this checklist when you compare providers and call for intake.
- Center-based, in-home, school-based, or a mix
- Full-day, half-day, or after-school hours
- How far you can realistically drive several times a week
- BCBA-to-child ratio and how often the BCBA observes sessions
- Whether RBTs deliver the day-to-day sessions
- Parent training built into the plan
- Current waitlist length
- Whether an autism diagnosis is required before intake
- Whether evaluations are available in-house
- Which commercial plans the center accepts
- Whether Maryland Medicaid is accepted
- Telehealth options if in-person coverage is limited
Compare a few nearby cities
Maryland families rarely choose a provider based on one city alone, because provider networks and commute times overlap across county lines. If you are in the Baltimore-Washington corridor, it is worth comparing Baltimore, Columbia, Silver Spring, and Rockville before you call.
