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

A DSM-5-TR autism spectrum diagnosis from a state-licensed physician, psychologist, or other qualified clinician; Optum asks for the diagnosing clinician and the confirming instrument at the assessment-authorization step. On a plan the Missouri mandate reaches, the ABA must additionally be ordered by the treating licensed physician or psychologist — the narrower list, and the one that decides whether the order is valid.^[1][3]

The diagnosis must be confirmed with at least one clinically validated tool. Optum names first-level instruments — the ADI-R, the ADOS-2 and the DISCO — and accepts second-level tools including the CARS-2, the RITA-T and the STAT. Capture which instrument was used, by whom and when; a diagnosis letter with no named tool is the most common reason an Optum assessment request stalls. Missouri's mandate names no instrument.^[1]

Gated on the provider, not just the code. Tele-supervision and virtual family training require the provider to be an approved Optum virtual-visits provider with a completed attestation on Provider Express, and the authorization itself must note virtual delivery. Optum frames telehealth as a supplement to in-person care rather than a replacement. Missouri's Medicaid telemedicine rule does not reach a commercial UnitedHealthcare plan.^[6]

UnitedHealthcare: "COB is administered according to the member's benefit plan and in accordance with law. We accept secondary claims electronically," and "If COB caused a delay, you have 90 days from the date of the primary carrier Explanation of Benefits to submit." For ABA through Optum: "bill the primary insurance carrier first, then notify Optum of your findings"; Optum processes "using industry-wide coordination of benefits (COB) standards and in accordance with benefit contracts and applicable state laws." Missouri's COB rule (20 CSR 400-2.030) governs fully insured group plans: when parents are not separated or divorced, "The benefits of the plan of the parent whose birthday falls earlier in a year are determined before those of the plan of the parent whose birthday falls later in that year" (same birthday: the plan that covered the parent longer); for divorced or separated parents a court decree naming the responsible parent controls. Self-funded plans follow their plan document. If another payer needs a UHC denial to pay, Optum's FAQ says to "Call the number on the back of the member's insurance card to request a denial." If the child also has Medicaid, this plan pays first: Medicaid is payer of last resort (42 CFR 433.139) — bill here, then send the EOB or denial to Medicaid, and get Medicaid's own prior auth too if the state requires it. TRICARE is secondary to this plan ("TRICARE shall be last pay," 32 CFR 199.8), and "CHAMPVA is the last payer to OHI" (38 CFR 17.276(d)).^{[8][11][6][12][13][14][15]}

The mandate sets no overall age limit on autism coverage — what it ages out is the dollar cap. RSMo § 376.1224 subjects ABA to “a maximum benefit of forty thousand dollars per calendar year for individuals through eighteen years of age,” a statutory base that is CPI-indexed (the Department of Commerce and Insurance publishes the adjusted figure annually). Coverage required under the section other than ABA “shall not be subject to the age and dollar limitations described in this subsection,” so OT, PT, speech, psychiatric and pharmacy care for autism carry no age cut-off and no dollar cap. Self-funded private ERISA plans are preempted from all of it; note Missouri's unusual reach into the state consolidated health care plan, self-insured governmental plans, MEWAs and self-insured school-district plans established on or after 1/1/2020.^[3]

Ask the plan: Benefits verification on the specific plan, via the payer portal or the number on the member’s card — ask whether RSMo § 376.1224 reaches this plan (it reaches fully-insured plans, the state consolidated health care plan, self-insured governmental plans, MEWAs and self-insured school-district plans established on or after 1/1/2020, but not private self-funded ERISA plans), and what the plan applies as this year’s dollar cap. The Missouri Department of Commerce and Insurance publishes the CPI-adjusted figure annually — quote that year’s number, never the $40,000 statutory base.

Yes on a plan the mandate reaches, and the statute is specific about who writes it: ABA “must be ordered by the treating licensed physician or psychologist” in a treatment plan, and must be supervised by a board-certified behavior analyst licensed under chapter 337. Capture the ordering physician or psychologist and the treatment plan they signed. Two Missouri rules work in the provider's favour once the order exists: the carrier may review the treatment plan no more than once every six months unless the provider agrees otherwise, and the cost of obtaining any review or treatment plan is borne by the plan. Self-funded private ERISA plans are outside the statute.^[3]

Ask the plan: Benefits verification on the specific plan, via the payer portal or the number on the member’s card — confirm first whether RSMo § 376.1224 reaches this plan. Where it does, capture the ordering licensed physician or psychologist and the treatment plan they signed, and the supervising chapter 337 licensed behavior analyst. Where it does not (a private self-funded ERISA plan), ask the carrier whether it requires a physician or psychologist order and in what form.

UnitedHealthcare publishes its own commercial clock: "Standard requests: up to 15 calendar days"; "Expedited requests: 72 hours"; "We may extend this time if we need additional information." Submit "at least 15 calendar days in advance, if possible, but … at least 5 business days before the planned service date." ABA requests route to Optum (Provider Express, AutismABA), where "All services require prior approval"; Optum's ABA FAQ says to request a continuation "no more than 30 days prior to the current approvals on file expiring" (that FAQ dates from October 2021). Missouri fully insured plans are bound by RSMo 376.1363: a carrier "shall make the determination within thirty-six hours, which shall include one working day, of obtaining all necessary information," with an approval phoned or sent electronically to the provider within 24 hours; concurrent review (continuing an approved course) is decided "within one working day of obtaining all necessary information." The clock starts when the file is complete, not when the form lands. Self-funded ERISA plans are outside state law and follow 29 CFR 2560.503-1: a pre-service decision "not later than 15 days after receipt of the claim" (one 15-day extension), 72 hours for urgent care, and an urgent extension request decided within 24 hours if made at least 24 hours before the approval expires. Where state law is stricter than UHC's 15 days, the law wins for fully insured members.^{[8][6][9][10]}

Ask the plan: Optum Behavioral Health (number on the member ID card): confirm whether the plan is fully insured or self-funded, which sets whether state law or UHC's 15-day ceiling governs.

Optum publishes no recency rule for the ASD diagnosis in the Supplemental Clinical Criteria cited here, and Missouri has no entry in Optum's State Mandates supplement to add one. What Optum does set is downstream: continued-service reviews every 4–6 months requiring updated standardized adaptive measures and progress measured the same way as baseline. Note the tension with § 376.1224 on a fully-insured Missouri plan — the statute limits plan review of the treatment plan to once every six months unless the provider agrees otherwise.^[1][2][3]

Ask the plan: Optum provider services or the assessment-authorization request on Provider Express — ask whether an evaluation of this age will be accepted before scheduling.

Optum's Supplemental Clinical Criteria set supervision at 1–2 hours per 10 hours of direct treatment, with a floor of at least one hour of 97155 per case per month. Missouri layers the licence on top as a coverage condition: § 376.1224 requires ABA to be supervised by a board-certified behavior analyst licensed under chapter 337, and RSMo 337.315 prohibits unlicensed practice outside enumerated exceptions. Missouri has no entry in Optum's ABA State Mandates supplement, so nothing modifies the national supervision criteria.^[1][2][3][4]

Permitted in three named pairs: supervision alongside direct care (97153 + 97155), group oversight (97154 + 97155), and parent training alongside direct care (97153 + 97156). Not covered at all: team meetings without the member present, 1:1 classroom aides, and services owed under IDEA.^[1]

Optum's exclusions are the operative setting rule: team meetings without the member, 1:1 classroom aides, and any service owed under IDEA are not covered, which makes the school and IEP picture a coverage question rather than background.^[1]

Optum does not publish the rendering-versus-billing NPI convention for ABA in the criteria cited here. Missouri's mandate supplies the statutory half for plans it reaches: reimbursement runs to the autism service provider or to the entity or group the supervising board-certified behavior analyst works for, and expressly covers line-therapist services delivered under that supervision.^[3][1]

Ask the plan: Optum provider services or the authorization letter on Provider Express — confirm the rendering-versus-billing NPI convention before the first claim.

Optum authorizes in four code clusters rather than against a per-day ceiling — assessment (97151, 97152), direct care (97153, 97154), multi-staff (0362T, 0373T) and QHP services (97155–97158) — with units flexing within a cluster without a new authorization. The number that bites runs the other way: utilization below 80 percent of authorized hours over a two-week window draws scrutiny at review. Missouri's own cap is a dollar cap on the benefit rather than a unit ceiling on the day.^[1][3]

Ask the plan: The authorization letter on Provider Express, and Optum provider services — ask whether any per-day MUE applies on top of the cluster structure.

Not published in the Supplemental Clinical Criteria. What Optum specifies is the review packet rather than the session note: continued-service reviews every 4–6 months want progress documented per targeted behavior using the same measurement methods as baseline, plus updated standardized adaptive measures. Note the Missouri overlay — on a fully-insured plan the carrier may not compel treatment-plan review more than once every six months.^[1]

Ask the plan: Optum provider services, or your Provider Express network manager — ask for the documentation standard applied at audit.
