Many Florida parents of children with Down syndrome hear two different answers about ABA therapy. One says Florida law requires coverage. The other, often from an insurer, says ABA for Down syndrome is not covered unless the child also has an autism diagnosis. Both can be true at the same time, for different plans. This article explains where the conflict comes from, which rule applies to your child's plan, and what to do if you get a denial. For what ABA itself looks like for children with Down syndrome, see ABA for children with Down syndrome.
What does Florida law say about Down syndrome and ABA?
Florida's Steven A. Geller Autism Coverage Act (sections 627.6686 and 641.31098, Florida Statutes) originally covered autism only. In 2016 the Legislature added Down syndrome (chapter 2016-222, Laws of Florida, from CS/CS/CS/HB 221). The 2015 statute read "Treatment of autism spectrum disorder through speech therapy..."; since 2016, subsection (3)(b) reads:
"Treatment of autism spectrum disorder and Down syndrome through speech therapy, occupational therapy, physical therapy, and applied behavior analysis."
The statute names Down syndrome as its own condition. It does not say the child must also have autism. Florida's Department of Financial Services (DFS) consumer page describes the covered services the same way: treatment of ASD and Down syndrome through speech, occupational and physical therapy and ABA.
The other rules of the law still apply. Treatment must be "prescribed by the insured's treating physician in accordance with a treatment plan," the plan may use medical necessity review and network rules, and coverage "may not be denied on the basis that provided services are habilitative in nature." That last point matters for many children with Down syndrome, because ABA usually teaches new skills rather than restoring lost ones. The full statute is explained in Florida's autism insurance law explained.
Which plans have to follow the Down syndrome rule?
Only the plans the Geller Act reaches:
- fully insured group plans from a Florida-licensed insurer, for employers that are not small employers (Florida defines a small employer as 1 to 50 employees);
- group HMO contracts of the same kind; and
- the Florida State Group Insurance Program for state employees.
The law does not reach individual or Marketplace plans, small-employer plans, self-funded employer plans, plans issued in another state, or federal programs. DFS says it "does not have authority over self-insured plans" under ERISA or "employer group health plans issued outside the State of Florida."
Age rules apply too. The law covers an "eligible individual": a child under 18, or someone 18 or older who is in high school and "has been diagnosed as having a developmental disability at 8 years of age or younger." For teens, keep a copy of the record that shows when your child was first diagnosed.
A real example: the 2025 Florida State Employees' PPO and HDHP booklet covers "Treatment for Autism Spectrum Disorder and Down syndrome," including ABA, for eligible children, limited to treatment prescribed by the treating physician under a treatment plan.
What do insurers' national policies say?
Large insurers write national medical policies that guide their reviewers. Several treat ABA for Down syndrome without autism as not proven:
| Policy | What it says | What it says about mandates and plan documents |
|---|---|---|
| Aetna Clinical Policy Bulletin 0554, Applied Behavior Analysis (last reviewed 10/14/2026) | Considers ABA "experimental, investigational, or unproven" for "Down Syndrome in the absence of an autism spectrum disorder (ASD) co-morbidity" | Describes itself as a partial, general description of benefits that "does not constitute a contract" |
| Evernorth (Cigna) Coverage Policy EN0499, Intensive Behavioral Interventions (effective 5/15/2026) | ABA "is considered not medically necessary for all non-autism spectrum disorders (ASD) indications" | "In the absence of a controlling federal or state coverage mandate, benefits are ultimately determined by the terms of the applicable benefit plan document." |
| Optum Behavioral Health Solutions ABA Supplemental Clinical Criteria (interim review April 2026) | Requires "A valid diagnosis of ASD (or other applicable diagnosis as required by governing laws)" | Lists Florida Commercial among states with mandated criteria and says "the state-mandated criteria controls" where they conflict |
Notice the pattern. Each policy leaves room for a state mandate. Cigna's says so directly, and Optum's names Florida. That is the opening a Florida family in a mandate-covered plan can use.
So which rule wins for my child?
| Your child's coverage | Which rule usually controls |
|---|---|
| Fully insured Florida large-group plan or group HMO | The Geller Act requires coverage of ABA for Down syndrome for eligible children; the insurer can still review medical necessity and require a physician-prescribed treatment plan |
| Florida State Group Insurance Program | Named in the statute; the 2025 booklet lists Down syndrome |
| Self-funded employer plan (including plans run by a big insurer's name or an administrator) | The employer's plan document; the insurer's national policy is often applied unless the plan says otherwise |
| Small employer or individual plan | The plan's own terms |
| TRICARE | The Autism Care Demonstration requires an autism diagnosis |
If your child has both Down syndrome and autism, the conflict mostly disappears: the plan reviews the request under its autism criteria. In that case, make sure the autism diagnosis is documented by a qualified professional, with the evaluator's name, credentials and the date, because policies such as Cigna's ask for those details. See ABA without an autism diagnosis for the wider picture.
What should I do if my plan denies ABA for Down syndrome?
- Find out what kind of plan you have. Ask HR: "Is our medical plan fully insured or self-funded, and in which state was the policy issued?" The guide to fully insured vs self-funded plans explains how to read the answer.
- Get the denial in writing, with the policy or plan language it relies on.
- If the plan is fully insured in Florida, appeal and cite the statute. A short line works: "My child is an eligible individual under section 627.6686, Florida Statutes (or 641.31098 for an HMO), which requires coverage of treatment of Down syndrome through applied behavior analysis. The national policy cited in the denial does not override this state mandate." Attach the physician's prescription and the treatment plan.
- Use every appeal level. After the internal appeal, you can usually ask for an independent external review. Florida uses the federal HHS-administered process or an accredited review organization the plan contracts with. See how to appeal an ABA denial in Florida.
- Ask DFS for help with a fully insured plan. The Insurance Consumer Helpline is 1-877-693-5236. For self-funded employer plans, DFS refers families to the U.S. Department of Labor's Employee Benefits Security Administration at 1-866-444-3272.
- If the plan is self-funded, read the Summary Plan Description for "Down syndrome" and "applied behavior analysis." If it is silent or excludes ABA for Down syndrome, you can still appeal on medical necessity, and you can ask the employer to add coverage. See how to ask an employer to add ABA.
This explains the law in general terms. Your plan, the appeal reviewers and, for legal disputes, a Florida attorney decide individual cases.
