Many Florida families move between Medicaid and private insurance over the years: a new job, a raise, a move, a child aging out of a program. ABA works quite differently under the two systems. This guide puts them side by side so you know what to expect before you switch, and what questions to ask.
One point up front: "private insurance" is not one thing. A plan bought on HealthCare.gov, a small business plan, a large employer's fully insured plan and a self-funded employer plan all follow different rules for ABA. We flag those differences below.
Medicaid vs private insurance for ABA: the side-by-side
| Question | Florida Medicaid | Private insurance |
|---|---|---|
| Is an autism diagnosis required? | No. Coverage is for behavior that impairs a major life activity (policy section 2.2). | Usually yes. Florida's mandate covers autism and Down syndrome; most insurer policies require an autism diagnosis. |
| Age limits | Under 21. | Florida's mandate: under 18, or 18 and older and still in high school if diagnosed by age 8. Plans may cover more. |
| What you pay | No copay or coinsurance for BA (s. 409.9081). | Deductible, copays and coinsurance apply. Under the mandate, they may not be less favorable than for physical illness. |
| Hours | Up to 40 hours a week as the policy ceiling; more may be approved if medically necessary under EPSDT. | Set by the plan's medical policy and medical necessity review. No state hour figure. |
| To start | Physician's order plus a Comprehensive Diagnostic Evaluation, then prior authorization. | Diagnosis report, a treatment plan prescribed by the treating physician (mandate), usually prior authorization. |
| Review period | Authorizations of up to six months. | Commonly about every six months with progress data. |
| Who decides | Your SMMC plan (or Acentra for fee-for-service). | The insurer or its behavioral health manager; for self-funded plans, the employer's plan administrator. |
| Providers | BA providers enrolled in Medicaid and in your plan's network. | Providers in the plan's network; out-of-network rules vary by plan. |
| If denied | Plan appeal, then a Medicaid fair hearing. | Internal appeal, then external review in most plans. |
| Regulator | AHCA. | Fully insured Florida plans: Florida's insurance regulators. Self-funded plans: federal law (ERISA). |
Does private insurance require an autism diagnosis when Medicaid does not?
Usually, yes, and this is the change that catches families off guard. The Medicaid BA coverage policy covers recipients under 21 "requiring medically necessary BA services to address behavior that impairs a recipient's ability to perform a major life activity," and lists safety, communication, self-stimulating, self-care and other behaviors. AHCA reported in August 2026 that about 1 in 4 BA recipients had no autism diagnosis in a recent six-month period. See Medicaid ABA without an autism diagnosis.
Private plans are different. Florida's autism insurance law (s. 627.6686) requires coverage of ABA for autism spectrum disorder and Down syndrome in the plans it applies to. Insurer medical policies we reviewed go further in narrowing it: Aetna's policy CPB 0554 treats ABA as unproven for "all other non-ASD indications," and Cigna's Evernorth policy EN0499 calls ABA "not medically necessary for all non-autism spectrum disorders (ASD) indications." If your child receives Medicaid ABA without an autism diagnosis, a private plan may not cover ABA at all. Ask before you drop Medicaid.
Will we pay more under private insurance?
Very likely. Medicaid BA has no copay or coinsurance. Private plans have deductibles, copays or coinsurance, and an out-of-pocket maximum. Florida's mandate says covered autism treatment may not be subject to dollar limits, deductibles or coinsurance "less favorable" than those for physical illness, which protects you from a separate, harsher cost structure, but it does not make ABA free.
Because ABA is often many hours a week, families commonly reach the plan's out-of-pocket maximum. Ask the plan for that figure in writing. A provider cannot simply waive your share either: Florida law (s. 817.234(7)(a)) treats routinely waiving copays or deductibles as insurance fraud. See real ABA cost math and why providers cannot waive copays.
Does every private plan have to cover ABA?
No. This is the second big difference:
- Large-group, fully insured plans issued in Florida (and the State Group Insurance Program) are covered by the mandate. Florida's small-employer definition is 1 to 50 employees, so the mandate reaches fully insured groups of 51 or more.
- Self-funded employer plans (often run through a third-party administrator) are governed by federal law, not Florida's mandate. Coverage depends on the plan document.
- Individual and small-group plans, including HealthCare.gov plans, are not required by Florida law to cover ABA. The Florida Department of Financial Services says ABA "may be a covered service" in those plans. Check each plan's benefits.
See fully insured vs self-funded plans to work out which type you have.
What about hours and authorizations?
Medicaid's policy says it covers "up to 40 hours per week" of BA intervention as set in the prior-authorized plan, and the federal EPSDT benefit allows more when medically necessary. Forty is a ceiling, not a target. Private plans use their own medical policies. For example, Aetna's ABA medical necessity guide describes comprehensive ABA as 10 to 25 hours a week for ages 0 to 7 and focused ABA as 1 to 20 hours a week, and Cigna's policy requires a fresh standardized assessment within 60 days before treatment starts. These are guidelines for review, not promises of hours.
Both systems re-review regularly. Medicaid authorizations run up to six months. Most private plans also ask for progress data about every six months, plus parent training goals and a discharge plan.
Can a child have both Medicaid and private insurance?
Sometimes. If your child stays eligible for Medicaid after getting a parent's employer plan, Florida law makes Medicaid the "payor of last resort" (s. 409.910): the private plan pays first. Providers enrolled in Medicaid must bill other insurers before Medicaid (s. 409.907(3)(f)). How that works for ABA in practice, including whether Medicaid can help with what the private plan does not pay, depends on both plans and on the provider's enrollment. See Medicaid as secondary insurance, and report any new coverage to your Medicaid plan and DCF.
Checklist: questions to ask before you switch
- Is the new plan fully insured or self-funded? Is it large group, small group or individual?
- Does it cover ABA, and for which diagnoses and ages? Ask for the plan language in writing.
- What are the deductible, coinsurance and out-of-pocket maximum for ABA?
- Does ABA need prior authorization, and what documents does the plan want (diagnosis report, treatment plan, assessment)?
- Which ABA providers are in network near you, and do they have openings?
- Is the diagnosis report recent enough for the plan? Some insurers ask for updated documentation when a report is several years old.
- Will your child still qualify for Medicaid as secondary coverage?

How Hope Center can help
Hope Center for Behavior Change works with Blue Cross Blue Shield (Florida Blue), Aetna (employer plans), Cigna (Evernorth), UMR, Personify Health and TRICARE East. Optum: in network for mental health therapy; for ABA, call us for the current status. If you are weighing a new plan, we can run a free benefits check and explain what ABA would likely cost under it, before you decide. We have no waitlist, and services usually start 3 to 5 business days after the insurer approves the plan. Our sliding scale can help with your share after insurance. A child who has Medicaid cannot be seen self-pay at Hope Center (center policy). Costs depend on your plan. Contact us, see insurance at Hope Center, or call 561-337-8865.
