If your child has an Aetna plan, you are in a better position than many families to know the rules ahead of time, because Aetna publishes its ABA criteria. This guide reads those documents for you: what Aetna asks for before it approves ABA, how many hours its guide describes, how it reviews progress, and the questions parents search most, such as whether Aetna covers ABA at school or for ADHD. We also explain where Florida law can change the answer.
One rule comes first: your plan document controls. Aetna's medical policies guide medical necessity review, but your specific plan decides whether ABA is a covered benefit at all.
Does Aetna cover ABA therapy for autism?
In many plans, yes. Aetna handles ABA for autism under Clinical Policy Bulletin (CPB) 0648, "Autism Spectrum Disorders," and its "Applied behavior analysis medical necessity guide." Whether your plan must cover it depends on the plan type:
- Fully insured Aetna employer plans in Florida, 51 or more employees: Florida's Geller Act (s. 627.6686, or s. 641.31098 for HMOs) requires coverage of ABA for eligible children with autism or Down syndrome.
- Self-funded employer plans that Aetna administers: the employer's plan document decides. Florida's mandate does not apply, but many such plans cover ABA.
- Small-group and individual plans: no Florida mandate; check the plan.

What does Aetna need before it approves ABA?
Aetna's medical necessity guide sets out the main requirements. In plain terms:
- A diagnosis of autism spectrum disorder under DSM-5 (ICD-10 codes F84.0 or F84.3 to F84.9).
- Measured impairment. A standardized scale, such as the Vineland-3, ABAS, VB-MAPP or ABLLS, completed in the past 12 months, showing functioning at least one standard deviation below the mean, or behavior that creates a significant risk of harm.
- Parent or guardian engagement. The guide requires a parent or guardian's "engagement and commitment" to participate in treatment.
- A treatment plan with measurable goals, written by the behavior analyst, which the provider submits for prior authorization.
The guide describes ABA as "a time-limited treatment that should result in progressive, measurable gains in functioning on a standardized measure." That sentence explains much of how Aetna reviews requests over time.
How many hours of ABA does Aetna approve?
Aetna's guide describes two models. These are typical ranges in Aetna's criteria, not a promise of what any child will be approved for.
| Model | Typical age | Typical hours per week | Typical length |
|---|---|---|---|
| Comprehensive ABA (many skill areas at once) | 0 to 7 | 10 to 25 | 1 to 2 years |
| Focused ABA (a limited set of goals or behaviors) | All ages | 1 to 20 | 1 to 4 years |
Supervision by the BCBA (protocol modification) may be authorized at 1 to 2 hours for every 10 hours of direct treatment. Hours above the typical range need a clear clinical reason in the treatment plan. The number your child is approved for comes from the BCBA's assessment, the treatment plan and Aetna's review. See how many ABA hours insurance covers.
Two practical tips. First, keep a copy of every assessment report and progress summary the BCBA sends to Aetna, so you can see the same numbers the reviewer sees. Second, if your child also gets speech or occupational therapy, tell the BCBA, because reviewers look for coordination between providers and for services that are not scheduled at the same time.
How often does Aetna review progress, and when does coverage end?
Aetna's guide says progress "is to be evaluated every six months." At each review, the provider sends updated assessment scores and data. The guide lists situations where coverage may end, including when medical necessity is no longer met, when a child improves by two or more standard deviations in several areas (or one standard deviation in a focused plan), or when a child shows less than one standard deviation of improvement in all areas across successive authorization periods.
In practice, that means your child's BCBA should plan for each six-month review from day one: clear baselines, measurable goals, regular data and documented parent participation. If hours are cut at a review, you can ask for a peer-to-peer conversation between the BCBA and Aetna's reviewer and you can appeal. See why ABA hours get cut.
Does Aetna cover ABA at school?
Often not during class. Aetna's CPB 0648 says: "Many Aetna plans exclude coverage of educational services. For example, speech therapy or ABA services during class would be excluded under these plans." (That bulletin's listed next review date has passed, so check for a newer version.)
This does not mean school-related goals are off limits. ABA in the home, clinic or community can target skills that help at school, and the school is responsible for educational services under your child's IEP. Florida law (s. 1003.572) also sets rules for when private providers can work with a child in a public school. Ask Aetna whether your plan covers ABA in a school setting, and get the answer in writing. More in ABA at school and insurance.
Does Aetna cover ABA for ADHD?
Generally no, not for ADHD alone. Aetna's CPB 0554, "Applied Behavior Analysis" (last reviewed October 14, 2026), considers ABA "experimental, investigational, or unproven" for "All other non-ASD indications." ADHD without autism falls in that group. If your child has both autism and ADHD, the autism diagnosis is what qualifies for ABA under Aetna's criteria.
For ADHD alone, ask your child's doctor about the treatments your plan does cover. Behavioral support for ADHD can also be paid for privately. See ABA coverage for ADHD.
Does Aetna cover ABA for Down syndrome?
Here Florida law and Aetna's national policy can point in different directions. CPB 0554 treats ABA as unproven for "Down Syndrome in the absence of an autism spectrum disorder (ASD) co-morbidity." But Florida's Geller Act requires coverage of ABA for Down syndrome for eligible children in fully insured large-group plans and group HMOs. Aetna's own guide notes that state or federal mandates can require coverage.
- In a fully insured Florida large-group Aetna plan or HMO: Florida law requires ABA coverage for Down syndrome for eligible children.
- In a self-funded plan Aetna administers: Aetna's policy and the plan document usually control.
If you receive a denial in the first situation, cite s. 627.6686 (or 641.31098) in your appeal. See ABA for Down syndrome.
Aetna ABA checklist for Florida parents
- Ask HR or Aetna whether your plan is fully insured or self-funded.
- Confirm ABA is a covered benefit and whether prior authorization is required.
- Get a copy of your child's diagnostic evaluation report. It should state the autism diagnosis clearly.
- Ask the BCBA which standardized assessment they will use and when it will be repeated.
- Ask about your deductible, coinsurance and out-of-pocket maximum for ABA.
- Mark your calendar for each six-month review.
- If anything is denied, ask for the written reason and the policy it cites, then use the appeal guide.
