Florida Medicaid ABA Referral Rules: Physician Order and Comprehensive Diagnostic Evaluation

Before a Florida Medicaid plan will review a request for applied behavior analysis, which Florida Medicaid calls behavior analysis (BA) services, a specific set of papers has to exist. Missing or thin paperwork is one of the most common reasons a request stalls. This guide walks through each document the state's coverage policy asks for, who can produce it, and what to check before you hand it over. For the bigger picture of the benefit itself (who qualifies, hours, cost and the 2025 move to managed care), start with our overview of Florida Medicaid ABA coverage in 2026.

What does Florida Medicaid require before ABA can start?

The rules are in the Florida Medicaid Behavior Analysis Services Coverage Policy (December 2024), adopted in Rule 59G-4.125 of the Florida Administrative Code. Section 2.2 of the policy says the child must be referred by an independent physician or practitioner, and that "the referral must include a physician's order for behavior analysis services and a comprehensive diagnostic evaluation (CDE) performed according to national evidence-based practice standards."

The Agency for Health Care Administration (AHCA), which runs Florida Medicaid, lists the steps for families on its behavior analysis information page:

1. Go to your child's doctor and get a written order for BA services.
2. Have a Comprehensive Diagnostic Evaluation completed by a qualified licensed practitioner.
3. Choose a BA provider in your child's plan network (or, if your child is not in a managed care plan, from AHCA's fee-for-service provider list).
4. The BA provider sends a service request to your child's plan, or to Acentra, AHCA's quality improvement organization, if your child is in fee-for-service.
5. The plan or Acentra reviews the request for medical necessity, and you and the provider are told the outcome.

So there are really three layers of paperwork: the order, the CDE, and the BA provider's own assessment. Each one is described below.

Who can refer a child for Medicaid ABA?

Section 2.2 says the referral must come from "an independent physician or practitioner qualified to assess and diagnose disorders related to functional impairment, including":

• a primary care physician with a family practice, internal medicine or pediatrics specialty;
• a board-certified or board-eligible physician specializing in developmental-behavioral pediatrics, neurodevelopmental pediatrics, pediatric neurology, or adult or child psychiatry; or
• a child psychologist.

The word "independent" matters. The policy defines an independent physician as one with financial independence under the federal physician self-referral law (42 U.S.C. 1395nn). In plain terms, the person referring your child should not have a financial relationship with the BA provider that will deliver services. If you are unsure whether your referral source qualifies, ask the plan before the request goes in.

For most families, the easiest starting point is the child's pediatrician. Our guide to who can diagnose autism in Florida explains the different specialists and how long each route tends to take.

What is a physician's order, and what should it say?

The order is a short written prescription for behavior analysis services. The policy does not publish a template, so the exact format is up to the doctor. In practice, a useful order:

• names your child and their date of birth;
• clearly orders "behavior analysis services" (or "applied behavior analysis");
• lists the diagnosis or the functional concerns the doctor is treating;
• is signed and dated by the referring physician or practitioner.

Keep a copy. The policy requires the BA provider to keep the original referral documentation in your child's record (section 6.2.1), and you may need it again if you change providers or plans.

What is a Comprehensive Diagnostic Evaluation (CDE)?

AHCA describes the CDE as "the national practice standard necessary to diagnose autism as well as other developmental or behavioral disorders and indicate the most appropriate treatment(s) to address the child's needs." It is a thorough review of your child's development and behavior, not a quick screening.

The policy sets a few firm rules:

• A CDE may be done by a multidisciplinary team or an individual practitioner.
• Either way, it must be led by a licensed practitioner working within their medical, developmental or psychological scope of practice.
• It must include assessment findings and treatment recommendations appropriate to your child.

AHCA lists examples of what CDE testing may include:

• a parent or guardian interview and a teacher assessment;
• diagnostic tools such as the ADOS-2, CARS2, M-CHAT-R, CSBS, ADI-R, Social Communication Questionnaire or Battelle Developmental Inventory (2nd edition);
• hearing and vision testing;
• genetic testing; and
• neurological or other medical testing.

Not every child needs every test. The evaluator chooses what fits. What the plan will look for is a report that explains how the evaluator reached their conclusions and what treatment they recommend. A report with a diagnosis but no treatment recommendations is a common gap. For a closer look at what reviewers read in an evaluation report, see what insurers look for in an autism evaluation report.

Does the CDE have to diagnose autism?

No. Florida Medicaid covers BA for recipients under 21 who need it to address behavior that impairs a major life activity, such as safety, communication, self-stimulating behavior or self-care. The policy does not require an autism diagnosis. The CDE still has to document your child's needs and recommend treatment. Our guide to Medicaid ABA without an autism diagnosis covers who qualifies on that basis.

How long is a CDE good for?

AHCA says one CDE is typically sufficient for the treatment period, but an updated CDE may be required in some situations, for example if your child's clinical condition changes or treatment lasts through more than one developmental phase. If your family moves to Florida, a new CDE may be needed depending on those factors and on the qualifications of whoever did the earlier evaluation. Managed care plans may also ask for copies of earlier CDEs they have not received.

What assessments does the ABA provider add?

Once a BA provider accepts your child, its lead analyst (usually a Board Certified Behavior Analyst) does a behavior assessment before any intervention starts. Section 4.2.1 of the policy requires the initial assessment to include two standardized tools:

The complete scoring reports, including outcome scores, must be sent with the prior authorization request. The lead analyst may add other tools. Reassessments are due at least every six months, and the two core tools must be repeated at least every 12 months.

Both tools rely on you. The Vineland-3 interview and the BASC-3 PRQ ask detailed questions about daily life at home, so plan for the time and answer as concretely as you can. The policy also expects parents and guardians to take part in treatment when possible and clinically appropriate, and continuation requests must include data on parent participation.

What usually slows a Medicaid ABA referral down?

From the policy's requirements, these are the gaps most worth checking before the request is sent:

• No signed order. A CDE alone is not enough. The order is a separate requirement.
• A CDE without treatment recommendations, or one not led by a licensed practitioner.
• An outdated or out-of-state CDE that the plan asks to have updated.
• Missing Vineland-3 or BASC-3 PRQ score reports from the BA provider.
• Wrong destination. Most children are in a Statewide Medicaid Managed Care plan, so the request goes to the plan, not to AHCA. Only fee-for-service requests go to Acentra.

Once a complete request is in, federal rules now set decision clocks for Medicaid plans. Our guide to the federal 7-day prior authorization rule explains them. If the plan denies or cuts the request, see Medicaid ABA appeals and fair hearings.

If you have questions about where your child's request stands, AHCA directs families to the Medicaid Helpline at 1-877-254-1055.

How is this different from private insurance paperwork?

Commercial plans have their own rules, set by the plan and, for many large employer plans, by Florida's autism insurance law. Most require an autism (or, under Florida's law, Down syndrome) diagnosis, a prescription or treatment order, and an assessment-based treatment plan, but the specific tools and forms differ by insurer. The Vineland-3 and BASC-3 PRQ requirements above are Florida Medicaid's rules; a commercial plan may ask for different measures.

If your child also has, or may soon have, a commercial plan, the evaluation you already have may still be useful. Whether a plan accepts it is up to that plan. Hope Center works with Blue Cross Blue Shield (Florida Blue), Aetna, Cigna (Evernorth), UMR, Personify Health and TRICARE East, with a sliding scale for your share after insurance. A child who has Medicaid cannot be seen self-pay at Hope Center (center policy), but your family can add employer or Marketplace insurance, which we accept. We can run a free benefits check and tell you what your plan asks for. See our insurance page or contact us.
