Does Aetna Cover ABA Therapy in Maryland?
For families in Maryland navigating an autism spectrum disorder (ASD) diagnosis, the road ahead often feels like a series of complex puzzles. One of the most important pieces of that puzzle is applied behavior analysis (ABA therapy).
Widely recognized as the most effective, research-based intervention for autism, ABA focuses on improving specific behaviors such as social skills, communication and reading while decreasing those that may be harmful or interfere with learning.
While the clinical benefits of ABA therapy are clear, the logistics can be daunting. Because ABA is most effective when delivered consistently and intensively, many children are prescribed between 10 and 40 hours of therapy per week.
In the “Old Line State,” families often wonder how they will balance this level of care with the associated costs.
If you are a Maryland resident with Aetna insurance, there is significant cause for optimism. Maryland’s state laws are among the most protective in the nation for autism services, and Aetna typically provides robust coverage to meet these requirements.

Does Maryland Mandate Coverage for ABA Therapy?
Maryland has a long-standing commitment to ensuring children with autism have access to necessary care. The state’s primary protection comes from the Habilitative Services Mandate.
Unlike rehabilitative services, which help a person regain a skill they lost, habilitative services help a child learn a new skill they haven’t yet mastered.

In Maryland, ABA therapy is legally classified as a habilitative service. This means that by law, most state-regulated insurance plans must provide coverage for ABA therapy as long as it is deemed medically necessary.
Key features of Maryland’s autism coverage laws include …
- No Arbitrary Caps: Maryland law prohibits insurance companies from setting ceilings or arbitrary limits on the number of ABA hours. Instead, they establish a floor of minimum coverage, but the actual hours authorized must be based on the child’s individual medical necessity.
- Broad Age Ranges: State-regulated plans must provide coverage at least until age 19, though many Maryland plans and Medicaid options extend this coverage up to age 21 to align with federal parity standards.
- Mental Health Parity: As of 2026, many Maryland insurers have reclassified ABA therapy as a mental health benefit. This shift has been beneficial for families, often resulting in lower copays and a more streamlined authorization process.
It is important to note that while state mandates cover individual plans and small-to-midsize group plans, “self-funded” plans from very large employers are governed by federal ERISA laws. Fortunately, Aetna’s national policies for these larger groups frequently include ABA coverage as a standard benefit.
Does Aetna Cover ABA Therapy in Maryland?
Aetna generally covers ABA therapy in Maryland for children diagnosed with ASD. Aetna’s policies in the state are designed to adhere to the Habilitative Services Mandate, ensuring that families have a pathway to the intensive care their children require.
Aetna’s coverage typically includes:
- Initial Functional Behavior Assessments (FBA) to determine a child’s baseline
- Direct One-on-One Therapy with a Registered Behavior Technician (RBT)
- Program Supervision by a Board Certified Behavior Analyst (BCBA)
- Parent Training, which is essential for ensuring that the skills a child learns in therapy are carried over into their home life
Because Aetna offers a wide range of products including HMO, PPO and Choice POS II plans, your specific out-of-pocket costs will depend on your plan’s deductible and coinsurance.
How Do You Get ABA Therapy Covered in Maryland?
To access your Aetna benefits for ABA therapy in Maryland, you will need to follow a structured clinical process. Following these steps ensures that the medical necessity of the treatment is clearly documented for the insurance company.
Obtain a Formal Diagnosis
Aetna requires a formal diagnosis of ASD from a “Qualified Health Care Professional.” In Maryland, this usually means a developmental pediatrician, a child neurologist or a licensed psychologist. The diagnosis must be supported by standardized testing tools.
Request a Referral
Once the diagnosis is confirmed, your doctor should provide a written referral or prescription specifically for ABA therapy. This document should ideally include a “Letter of Medical Necessity” (LMN) explaining why ABA is the recommended treatment.
Complete a Professional Assessment
You will then partner with an ABA provider, such as Blue Gems ABA. A BCBA will conduct an initial assessment of your child. This assessment results in a comprehensive treatment plan that outlines specific, measurable goals and the requested number of hours per week.
Get Prior Authorization
In Maryland, Aetna requires prior authorization before the first therapy session can begin.
Your ABA provider will submit the treatment plan and the medical documents to Aetna’s clinical review team. They will review the request to ensure it meets their medical necessity criteria.
Follow Up with Regular Progress Reviews
Aetna typically authorizes therapy in six-month blocks.
Every six months, your BCBA will submit a progress report. As long as the data shows that the child is benefiting from the therapy and that continued intervention is necessary to meet developmental milestones, coverage is usually renewed.
