Two families can both have "Aetna" or "Florida Blue" on their cards and still face very different rules for ABA. One reason is funding (fully insured or self-funded). The other is network type: PPO, HMO, EPO or POS. Network type decides which ABA providers you can use, whether you need a referral, and what happens if no in-network provider can serve your child. This guide compares the four types and explains the Florida protections that come with an HMO.
What do PPO, HMO, EPO and POS actually mean?
HealthCare.gov, the federal health insurance site, defines them this way:
- HMO (Health Maintenance Organization): "A type of health insurance plan that usually limits coverage to care from doctors who work for or contract with the HMO." It "generally won't cover out-of-network care except in an emergency."
- PPO (Preferred Provider Organization): "A type of health plan where you pay less if you use providers in the plan's network." You "can use doctors, hospitals, and providers outside of the network without a referral for an additional cost."
- EPO (Exclusive Provider Organization): "A managed care plan where services are covered only if you use doctors, specialists, or hospitals in the plan's network (except in an emergency)."
- POS (Point of Service): a plan where "you pay less if you use doctors, hospitals, and other health care providers that belong to the plan's network," and which requires "a referral from your primary care doctor in order to see a specialist."
A high-deductible health plan (HDHP) is not a separate network type. An HDHP can be a PPO or an HMO; the State of Florida, for example, offers both an HDHP PPO and HDHP HMOs to its employees.
How do the plan types compare for ABA?
| Plan type | Out-of-network ABA | Referral needed? | What to watch for |
|---|---|---|---|
| PPO | Usually covered at a lower rate; provider may bill you the difference | Not for out-of-network care, per HealthCare.gov's definition; ABA still usually needs prior authorization | Higher coinsurance and separate deductible out of network |
| HMO | Generally not covered except emergencies | Some HMOs require one; check your evidence of coverage | The HMO's ABA network in your county may be small |
| EPO | Generally not covered except emergencies | Varies by plan | Network limits similar to an HMO; check the referral rules |
| POS | Often covered at a higher cost | Yes, for specialists | Keep the referral current along with the authorization |
Two cautions. First, a referral and a prior authorization are different things. A referral is your primary care doctor sending you to a specialist; a prior authorization is the plan approving a specific service. Most plans require prior authorization for ABA treatment no matter the network type. Second, Florida's autism mandate lets plans apply "participating provider requirements" and utilization review (s. 627.6686(4)(d)), so a mandated ABA benefit can still be limited to the network.
What should I check before choosing a plan for ABA?
- Is our ABA provider in network for this exact plan? Networks are product-specific. Give the plan the provider's name and NPI and ask about your plan, not the carrier in general.
- Does the plan cover ABA in the settings we need? Home, center, school or daycare rules differ.
- Are there out-of-network benefits? If yes, what are the deductible and coinsurance, and can the provider bill the difference?
- Who manages behavioral health? Some plans use a separate company for authorizations and network.
- Is a referral or doctor's prescription required, and how long does it last?
- What are the in-network deductible, copay or coinsurance, and out-of-pocket maximum?
Our insurance call script turns these into word-for-word questions.
What does going out of network cost on a PPO?
A PPO pays out-of-network providers based on its own allowance, not the provider's bill. The State of Florida's employee PPO booklet explains the risk in capital letters: "LIMITED BENEFITS WILL BE PAID WHEN NONPARTICIPATING PROVIDERS ARE USED," and "Non-participating providers may bill insureds for any difference in the amount." Its 2025 HDHP summary shows autism treatment at 80 percent of the allowed amount in network and 60 percent of the allowance out of network, both after the deductible.
For ABA, which can run many hours a week, that gap adds up. Compare the full yearly cost, not just the coinsurance percentage. See in-network vs out-of-network ABA.
What if my HMO or EPO has no ABA provider who can serve my child?
Ask the plan, in writing, to help you find an in-network provider with an opening and staff for your area. If none exists, ask whether it will authorize an out-of-network provider at in-network cost sharing, sometimes through a single case agreement. In a September 2026 bulletin on mental health parity, the U.S. Department of Labor said that when an in-network mental health provider is not available, plans should "consider all available options." That bulletin applies to plans under federal parity rules and does not name ABA, but it is useful to quote. See single case agreements for ABA.
What extra protections do Florida HMO members have?
Florida HMOs are governed by chapter 641 of the Florida Statutes, which includes an HMO-specific grievance law, s. 641.511. It applies to HMOs, not to PPO or EPO policies from insurers, which follow their policy terms and federal appeal rules. Key points in s. 641.511:
- Grievance deadline for the HMO: the HMO must resolve a grievance within 60 days (90 days if it needs information from outside its service area).
- Expedited review: for urgent situations, a decision "in no event more than 72 hours after receipt" of the request.
- Services continue during expedited review of a concurrent decision: when the review concerns ongoing care, "the service shall be continued without liability to the subscriber until the subscriber has been notified" of the decision. This can matter if an HMO cuts ABA hours at reauthorization.
- Internal review panel: a subscriber can ask for a review panel within 30 days of the HMO's final adverse determination.
For group HMO plans that are also subject to ERISA, the federal claims regulation sets the minimum standard. Florida's HMO autism statute, s. 641.31098, mirrors the insurer mandate, so a fully insured group HMO for an employer with 51 or more employees must cover ABA for eligible children. Our appeals guide and what to do when ABA hours are cut walk through using these rules.
Which plan type is right for an ABA family?
There is no single answer. A rough guide:
- An HMO or EPO can work well when your chosen ABA provider is in network and the premiums are lower. The Florida HMO grievance law is an added protection.
- A PPO gives flexibility if you may need an out-of-network provider, at a higher premium and higher out-of-network costs.
- An HDHP (PPO or HMO) can make sense if you can fund a health savings account, since ABA families often reach the deductible early. See using an HSA or FSA for ABA.
Make the choice with real numbers: your expected weekly ABA hours, the plan's in-network cost sharing and the out-of-pocket maximum. Our open enrollment checklist helps.
