UnitedHealthcare / Optum ABA coverage in Ohio: the intake guide.

The SCC set no expiry on the ASD diagnosis itself; what they require is that the DSM-5-TR diagnosis and severity level be confirmed and documented by the diagnosing clinician using validated tools. The clocks run on review instead: where there has been inadequate or no demonstrable progress with targeted symptoms or behaviors within a 6-month period, or goals have not been achieved within the estimated timeframes, the reasons must be assessed and interventions modified; and continued-service review specifically addresses utilization of prior-authorization-period hours below 80% over a 2-week period, which requires documented barriers.^[1]

A valid diagnosis of ASD (or other applicable diagnosis as required by governing laws) must be issued by a state licensed physician, psychologist, or other state licensed clinician qualified to make such a diagnosis according to the DSM-5-TR criteria.^[1]

The SCC give a three-tier, explicitly non-exhaustive list and require the diagnosing clinician to confirm and document the DSM-5 diagnosis and severity level using at least one clinically validated tool. First-level screening tools: Autism Behavior Checklist, CHAT / M-CHAT, CSBS-DP-IT Checklist, Autism Screening Questionnaire, Autism Quotient, Childhood Autism Screening Test. Second-level screening tools: CARS and CARS-2, RITA-T, STAT. Formal diagnostic tools used as part of a comprehensive diagnostic evaluation: ADI-R, ADOS and ADOS-2, and DISCO. Treatment intensity must then be set from a baseline measured with at least one validated tool from a named list including ATEC, VB-MAPP, ABLLS and ABLLS-R, AFLS, PEAK, SSIS, RBS-R, SRS, Vineland and CFQL-2.^[1]

The SCC require no separate physician referral or order; what they require is prior authorization for ABA, unless otherwise specified or mandated by contract or law. In practice UnitedHealthcare administers this as a two-step Optum flow on Provider Express — an authorization for the assessment, then a second for treatment — with continued-service reviews on the authorization cycle. For a fully insured Ohio plan the state mandate adds an ordering requirement the carrier policies do not: R.C. 3923.84 makes coverage contingent on the services being prescribed or ordered by a psychologist trained in autism, a developmental pediatrician, or — since Senate Bill 196 took effect March 20, 2025 — a clinical nurse specialist or certified nurse practitioner specialising in pediatric health. Prior authorization is written into the mandate as the other condition of coverage. Non-grandfathered individual and small-group plans are carved out, and self-funded ERISA plans sit outside state insurance law. Ohio matters here: the SCC’s own benefit considerations list "Ohio Fully Insured" and "Ohio Medicaid" among the lines of business for which the ABA State Mandates document supplies state-mandated criteria that control where they conflict with this document.^[1][2]

Optum’s ABA Supplemental Clinical Criteria carry no age criterion — coverage turns on the member-specific benefit plan, which supersedes the guideline, and on any federal or state regulatory requirement that supersedes the benefits. Ohio sets a floor rather than a cap: R.C. 3923.84 requires at least 20 hours a week of clinical therapeutic intervention for an insured under age fourteen and says the section "shall not be construed as limiting benefits that are otherwise available." Non-grandfathered individual and small-group plans and limited-benefit policies are carved out by name, and self-funded ERISA plans are exempt by preemption. Ohio matters here: the SCC’s own benefit considerations list "Ohio Fully Insured" and "Ohio Medicaid" among the lines of business for which the ABA State Mandates document supplies state-mandated criteria that control where they conflict with this document.^[1][2]

Ask the plan: Provider Express benefits check under a One Healthcare ID, or the behavioral health number on the member ID card — establish fully insured vs. self-funded ERISA first.

For insured Ohio plans the state clock is faster than the federal floor. When the request is submitted electronically, the insurer “shall respond to all prior authorization requests within forty-eight hours for urgent care services, or ten calendar days for any prior authorization request that is not for an urgent care service, of the time the request is received” (R.C. 3923.041 for sickness-and-accident insurers and public employee benefit plans; R.C. 1751.72 for health insuring corporations). An incomplete request must get a reply naming the missing information. Plans outside those statutes, such as a self-funded private employer plan, are held to the federal floor: pre-service decisions “not later than 15 days after receipt of the claim,” one 15-day extension, and urgent care “not later than 72 hours after receipt” (29 CFR 2560.503-1). The same floor applies to non-grandfathered individual and marketplace plans (45 CFR 147.136).^[5][6][7][8]

Ask the plan: Optum Behavioral Health (number on the member ID card): whether the plan is insured in Ohio (R.C. 3923.041 / 1751.72 apply), self-funded (ERISA floor) or grandfathered; the plan’s own standard and urgent turnaround for ABA; and how far ahead of expiry a reauthorization must be filed.

Ohio’s COB rule sets the order for a child on both parents’ plans: “The plan of the parent whose birthday falls earlier in the calendar year is the primary plan”; if the birthdays match, the plan that has covered a parent longer goes first. For parents who are divorced, separated or not living together, a court decree assigning health costs controls. Without one, the order is the custodial parent’s plan, then the custodial parent’s spouse’s, then the non-custodial parent’s, then the non-custodial parent’s spouse’s (OAC 3901-8-01). That rule governs contracts issued in Ohio. 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. Ohio Medicaid “must be the last payer” (OAC 5160-1-08). TRICARE “pays after all other health insurance, except for” Medicaid. CHAMPVA “is always the secondary payer, except to Medicaid.” If this 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.^{[9][10][11][12]}

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 and issued in Ohio (OAC 3901-8-01 order applies) or self-funded (the plan document’s COB clause applies).

Not addressed. The ABA Supplemental Clinical Criteria set no telehealth rules, place-of-service codes or modality limits for ABA; telehealth terms for a commercial member come from the plan’s own telehealth policy rather than from this guideline.^[1]

Ask the plan: Provider Express (Clinical Resources → ABA Information) or the behavioral health number on the member ID card — ask which ABA codes are payable by telehealth on this plan and with which POS code.

Consistent with CASP standards of care, direct case supervision is required at one to two hours for every ten hours of direct treatment per week. Technicians must be under the applicable supervision of a BCBA or a licensed behavioral health clinician and should be Registered Behavior Technicians or another appropriately certified behavior technician as allowable by state mandate. Optum adds that it is not recommended that parents serve in an RBT role, and that a BCBA acting in a supervisory role for a parent serving as RBT for their own child would violate the ethics code with a duty to self-report.^[1]

The SCC set no numeric hour cap — the number of service hours requested must be justified by the member’s documented clinical need according to level of impairment, symptom severity, treatment history and response, at the least restrictive and most clinically appropriate level. The operative review trigger runs the other way: utilization below 80% of prior-authorization-period hours over a two-week period is specifically addressed at continued-service review and requires documentation of barriers and how they will be addressed.^[1]

ABA must be provided at the least restrictive and most clinically appropriate level, with generalization and maintenance of skills outside the treatment environment into natural settings such as home and community forming part of the continued-service test. Not covered: services that are not ABA therapy, such as a 1:1 aide delivered simultaneously during classroom instruction, or services covered under IDEA. School-based ABA does allow coordination of services and covers teacher training, meetings with school personnel, and observations in the school setting, and the treatment plan is expected to coordinate with the school and any IFSP or IEP.^[1]

Once an ASD diagnosis is confirmed, a credentialed ABA provider is identified for the member: a master’s- or doctoral-level Board-Certified Behavior Analyst, or a licensed behavioral health clinician who has attested to sufficient expertise and been credentialed to provide ABA. A BCaBA or non-licensed individual works under the direct supervision of a BCBA or licensed behavioral health clinician who takes responsibility for the individual’s care, assisting in assessment or implementing a treatment plan developed by that BCBA or clinician.^[1]

Not addressed. The ABA Supplemental Clinical Criteria are a medical-necessity document and say nothing about billing 97153 and 97155 for the same clock time; direct case supervision is defined as occurring concurrently with direct treatment, but the reimbursement consequence is not stated there.^[1]

Ask the plan: Optum Provider Express National Network Manual and the participating-provider agreement, or a written coding determination from Optum.

Not addressed. The ABA Supplemental Clinical Criteria specify what must be documented for coverage — progress by targeted symptom and behavior, standardized and norm-referenced measures, caregiver involvement, barriers — but not who must sign a session note or within what time.^[1]

Ask the plan: Optum Provider Express National Network Manual (documentation standards) and the participating-provider agreement.
