Aetna ABA coverage in Florida: the intake guide.

Aetna sets no expiry on the ASD diagnosis itself, but it puts a 12-month clock on the functional evidence: “there is demonstration of functional impairment on a standardized scale of functioning in the past 12 months… the impairment must be at least one standard deviation below the population mean OR represent a significant risk of harm to self or others.” In practice that is the recency rule intake must schedule around — a current standardized functional score, not a fresh diagnostic report. Reauthorization commonly runs on a roughly six-month cadence.^[6]

Broad, and tied to scope of practice: the ASD diagnosis must be “obtained by an appropriate provider (i.e. licensed psychologist/psychiatrist, physician or other health care professional qualified to diagnose mental health conditions within their scope of practice).” CPB 0648 lists who Aetna expects to be involved in an ASD evaluation — “board certified behavioral analyst; developmental pediatrician; neurologist; occupational therapist; physical therapist; primary care provider; psychiatrist; psychologist; or speech-language pathologist and audiologist” — evaluated by “the appropriate certified/licensed health care professional.” The diagnosis itself must be DSM-5 ASD (ICD-10 F84.0, F84.3–F84.9); ABA for other indications is considered experimental, investigational or unproven.^[6][2]

Two layers, and intake needs both. For the diagnosis, CPB 0648 names the instruments Aetna expects alongside clinical assessment: “Autism Diagnostic Interview-Revised (ADI-R), Autism Diagnostic Observation Schedule-2nd edition (ADOS-2), Childhood Autism Rating Scale 2nd edition (CARS-2) and Asperger Syndrome Diagnostic Scale.” For medical necessity, the ABA Medical Necessity Guide requires a standardized scale of functioning administered in the past 12 months — “for instance, the Vineland Adaptive Behavior Scales 3 (VABS-3), the Adaptive Behavior Assessment Scale (ABAS), VB-MAPP or ABLLS” — scoring at least one standard deviation below the population mean, or documenting a significant risk of harm.^[6][2]

Aetna publishes none. The ABA Medical Necessity Guide gives a “typical age range” of 0–7 years for comprehensive ABA and “all ages” for focused ABA, which is planning guidance, not a benefit boundary, and CPB 0554/0648 set no age criterion. The age terms that bite in Florida come from the Geller Act, and only for the plans it reaches: an eligible individual is “under 18 years of age or 18 years of age or older and in high school” AND “diagnosed as having a developmental disability at 8 years of age or younger.” That mandate covers fully-insured large-group and state-employee plans only — individual, individually underwritten and small-employer plans are excluded by the statute’s own text, and self-funded ERISA plans sit outside state reach. Federal parity limits how hard age terms can be enforced against covered group plans, so treat an age-based decline on a large-group plan as an escalation, not an answer.^[6][3]

Ask the plan: Plan funding type and group size first, then a live benefits verification — the mandate, not the carrier policy, is what carries the age terms.

Aetna gates ABA with precertification rather than a referral: form GR-69017-4, submitted through Availity or by phone, for both the assessment and treatment. Neither CPB 0554, CPB 0648 nor the ABA Medical Necessity Guide publishes a referral or physician-order requirement — the Guide mentions “involvement of, or referrals to, appropriate health care, community or supplemental resources” as a quality element, not an entry condition. Whether the specific plan needs a PCP referral is a benefit-design question, not a policy one.^[6][1]

Ask the plan: The member’s benefit document and Aetna precertification at the number on the ID card — ask whether a PCP referral is required in addition to precertification.

No Florida statute sets the decision deadline: § 627.42392, Fla. Stat. governs the prior authorization form, not the clock. The federal claims rule sets the floor for employer plans, whether insured or self-funded, and for non-grandfathered individual and marketplace plans: a pre-service decision “not later than 15 days after receipt of the claim,” with one 15-day extension, and urgent care “not later than 72 hours after receipt” (29 CFR 2560.503-1(f)(2); 45 CFR 147.136). A plan may be faster. Aetna’s behavioral health provider manual publishes no decision timeframe.^{[8][9][10][11]}

Ask the plan: Aetna Behavioral Health precertification (number on the member ID card): the plan’s standard and urgent turnaround for ABA requests, whether the clock starts at receipt or at a complete request, and how far ahead of expiry a reauthorization must be filed. Also ask whether the plan is grandfathered, since grandfathered plans are outside 45 CFR 147.136.

For a child covered on both parents’ group plans, Florida’s COB statute sets the order: “The benefits of the policy or plan of the parent whose birthday, excluding year of birth, falls earlier in a year are determined before” the other parent’s. For divorced or separated parents, the order is the custodial parent’s plan, then the custodial parent’s spouse’s plan, then the non-custodial parent’s, unless a court decree assigns health costs to one parent. The statute reaches group policies and group plans issued in Florida; whether a self-funded employer plan follows it or its own plan document’s COB clause is a question for that plan. Public coverage pays after this plan. Medicaid is the payer of last resort (Rule 59G-1.052). TRICARE “pays after all other health insurance, except for” Medicaid. CHAMPVA “is always the secondary payer, except to Medicaid.” If the other plan denies because its rules were not followed, including its prior authorization, TRICARE “may also deny the claim.” So get this plan’s authorization even when a public program is secondary.^{[12][13][14][15]}

Ask the plan: Ask the family for both parents’ cards and birth dates, and ask the employer or HR whether each plan is fully insured (Florida statute order applies) or self-funded (the plan document’s COB clause applies).

Not published. Aetna’s ABA materials — CPB 0554, CPB 0648 and the ABA Medical Necessity Guide — say nothing about telehealth delivery of ABA: no code list, no place-of-service codes, no modifiers and no limits. Do not assume the Florida Medicaid position either, which is narrower than most commercial practice (telemedicine for caregiver training only).

Ask the plan: Aetna’s telemedicine policy and provider services at the number on the member’s ID card — confirm which ABA codes pay by telehealth on that specific Florida plan before scheduling remote sessions.

A duty, not a number. Where a state mandate, plan document or contract allows services from someone neither state-licensed nor BACB-certified, “there must be supervision and direction of the unlicensed or non-certified providers in line with practice standards.” The ABA Medical Necessity Guide publishes no supervision percentage, ratio or caseload cap — the operative standard is professional practice plus whatever the participating-provider agreement adds. Florida supplies no licensure backstop of its own: the state licenses no behavior analysts, and the Geller Act keys ABA coverage to s. 393.17, F.S. certification (BACB/FL-CBA) or Chapter 490/491 licensure.^[6][3]

The claim carries the analyst, not the technician: “services must be provided directly or billed by licensed behavior analysts (in states with behavior analyst licensure laws), board-certified behavior analysts, or licensed psychologists where behavior analysis is within their scope of practice definition, unless state mandates, plan documents or contracts require otherwise.” Florida has no behavior-analyst licensure law, so the operative credential is BACB certification (or the legacy FL-CBA, or Chapter 490/491 licensure) — and the Geller Act keys covered ABA to exactly that s. 393.17 certification or 490/491 licensure. The escape clause matters: a state mandate or your contract can move the line, so confirm before enrolling technicians.^[6][3]

Aetna publishes no place-of-service code list for ABA. The one boundary it does state is the schools carve-out: pursuant to applicable law Aetna “is not required [to] provide services to a child under an individualized education program or any obligation imposed on a public school by the Individuals with Disabilities Education Act.” That limits paying for what the IEP owes; it is not a blanket ban on the school setting, and it yields to a stronger state mandate. Florida’s mandate does not itself name settings, so where ABA is payable in a school, in the community or in a group home is a benefit-document question on Aetna plans.^[6][3]

Ask the plan: The member’s benefit document, and Aetna provider services for whether school-setting ABA is payable on that plan.

Not published. Neither the ABA Medical Necessity Guide nor Aetna’s clinical policy bulletins on ABA address whether 97153 and 97155 may be billed for the same clock time; Aetna carries the concurrency question in its claim editing rather than in a public policy.

Ask the plan: Aetna precertification/provider services at the number on the member’s ID card, and the plan’s own reimbursement schedule — ask specifically whether 97155 pays alongside 97153 when analyst, technician and member are all face-to-face.

Not published. Aetna’s ABA documents set medical-necessity criteria and precertification requirements for 97151–97158, 0362T and 0373T but no per-day unit ceiling and no statement of which MUE table applies. The Guide’s intensity table is descriptive rather than limiting — 10–25 hours a week over 1–2 years for comprehensive ABA, 1–20 hours a week over 1–4 years for focused ABA — and the Geller Act’s nominal $36,000-a-year and $200,000-lifetime ABA caps are dollar limits, not unit limits, and are arguably unenforceable against parity-subject group plans.^[6][3]

Ask the plan: Aetna provider services; confirm before promising a family more than four hours a day of 97153.

Not published in Aetna’s ABA materials — no rule on who signs a session note or within what window.
