What Is the Maryland Autism Waiver and How Does It Cover ABA Therapy?
The Maryland autism waiver, officially called the Home and Community-Based Services (HCBS) waiver for individuals with autism spectrum disorder (ASD), is a state-funded program that helps families access critical therapies, including Applied Behavior Analysis (ABA). This waiver is designed to support individuals with autism in living and thriving in their communities rather than in institutional settings. ABA therapy, which is based on the science of learning and behavior, is a core service covered under the waiver for many families.
Under the waiver, ABA therapy hours are not a fixed number but are tailored to each person's unique needs. A qualified professional, typically a Board Certified Behavior Analyst (BCBA), conducts an assessment to determine the appropriate number of hours per week or month. These hours can include direct one-on-one therapy, parent training, and supervision by the BCBA. The goal is to provide enough support to help the individual develop skills in communication, social interaction, daily living, and behavior management.
Who Is Eligible for the Maryland Autism Waiver?
Eligibility for the waiver requires meeting several criteria set by the Maryland Department of Health and the Developmental Disabilities Administration (DDA). Generally, an individual must:
- Have a formal diagnosis of autism spectrum disorder from a qualified professional, such as a developmental pediatrician or psychologist.
- Be a Maryland resident and meet income and resource limits for Medicaid or be eligible for waiver services through the DDA's priority system.
- Demonstrate a need for the level of care that would otherwise be provided in a facility, such as an intermediate care facility for individuals with intellectual disabilities.
- Be at least 3 years old (services for children under 3 are typically covered through Maryland's Early Intervention program, Infants and Toddlers).
It's important to note that the waiver has a limited number of slots, and there may be a waitlist. Families are encouraged to apply as early as possible and stay in touch with their local DDA office for updates.

How Many ABA Therapy Hours Can You Get Through the Maryland Autism Waiver?
The number of ABA therapy hours approved under the Maryland autism waiver varies widely. Unlike some private insurance plans that may cap hours at a specific number per week, the waiver is designed to be more flexible. Hours are determined through a person-centered planning process and a functional assessment. For example, a young child with significant communication and behavioral challenges might receive 20 to 30 hours per week of direct ABA therapy, while an older child or adult with milder needs might receive 5 to 10 hours per week.
The assessment considers factors such as the individual's age, current skill levels, challenging behaviors, and family goals. The BCBA will create a treatment plan that outlines the recommended hours, which must be approved by the DDA. It's not uncommon for hours to be adjusted over time as the individual makes progress or as needs change. Families should regularly review the plan with their provider to ensure it remains appropriate.
What Services Are Included in ABA Hours?
ABA therapy under the waiver includes several components, all of which are part of the approved hours:
- Direct therapy: One-on-one sessions with a registered behavior technician (RBT) or BCBA, focusing on skill acquisition and behavior reduction.
- Parent training: Time spent teaching parents and caregivers strategies to support their child's development and manage behaviors at home.
- BCBA supervision: Regular oversight of the therapy program, including data analysis, plan adjustments, and team meetings.
- Assessment and planning: Initial and ongoing assessments to measure progress and update goals.
All these services are provided by a BCBA-led team, ensuring high-quality, evidence-based care.
How to Apply for the Maryland Autism Waiver for ABA Therapy
Applying for the Maryland autism waiver involves several steps, and it's wise to start early. Here's a general overview:
- Get a diagnosis: If your child doesn't already have a formal autism diagnosis, seek one from a qualified professional. This is the foundation of the application.
- Contact your local DDA office: The DDA has regional offices throughout Maryland. Reach out to the one serving your county to express interest in the waiver and request an application packet.
- Complete the application: You'll need to provide detailed information about the individual's diagnosis, functional abilities, and support needs. This often includes medical records, school reports, and therapy evaluations.
- Undergo a needs assessment: The DDA will conduct an assessment to determine eligibility and the level of care needed. This may involve interviews and standardized tools.
- Wait for approval and slot availability: If eligible, you'll be placed on the waiver registry. When a slot opens up, you'll be notified and can begin choosing providers.
Throughout this process, it can be helpful to work with a service coordinator or advocate who understands the system. Also, consider using a free matching service like ABA Centers Near Me to find BCBA-led providers that accept the waiver once you're approved.

Common Mistakes to Avoid When Navigating the Maryland Autism Waiver
Families often encounter challenges when applying for or using the waiver for ABA therapy. Here are some pitfalls to watch out for:
- Waiting too long to apply: The waiver can have waitlists that last months or even years. Apply as soon as you have a diagnosis, even if you're not sure you'll need the services immediately.
- Not gathering all required documents: Missing paperwork can delay your application. Keep a folder with copies of the diagnosis, medical records, and any previous therapy reports.
- Assuming hours are fixed: Some families think the approved hours are permanent. In reality, you can request a reassessment if your child's needs change, such as after a significant progress or a new challenge.
- Choosing a provider without verifying waiver acceptance: Not all ABA providers accept the Maryland autism waiver. Always confirm with the provider that they are enrolled as a waiver provider before starting services.
- Neglecting parent training hours: Parent training is a valuable part of ABA therapy and is included in the approved hours. Make sure to use these sessions to learn strategies that support your child at home.
