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

Optum's Supplemental Clinical Criteria set no recency clock on the ASD diagnosis. What they require instead is current assessment: the comprehensive diagnostic evaluation and functional assessment "form the basis for the treatment plan," baseline skills and norm-referenced measures must reflect the individual's "specific and current abilities," and continued coverage rides on documentation of movement from baseline at each 4–6 month review.^[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 diagnosis according to the diagnostic criteria based on the DSM-5-TR." The diagnosing clinician must also confirm and document the severity level.^[1]

The DSM-5-TR diagnosis and severity level must be "confirmed and documented by the diagnosing clinician using at least one clinically validated tool," on a three-tier list: first-level screening (ABC, CHAT/M-CHAT, CSBS-DP-IT Checklist, ASQ, AQ, CAST), second-level screening (CARS/CARS-2, RITA-T, STAT) and formal diagnostic tools used in a comprehensive evaluation (ADI-R, ADOS/ADOS-2, DISCO). Treatment intensity must then be set against at least one validated measurement tool — ATEC, VB-MAPP, ABLLS/ABLLS-R, AFLS, PEAK, SSIS, RBS-R, SRS, VABS or CFQL-2.^[1]

No physician referral or order is required. The front door is Optum's two-step authorization on Provider Express — "Prior authorization is required for ABA (unless otherwise specified or mandated by contract or law)" — with the diagnosis, the credentialed ABA provider and the assessment package standing in for a referral.^[1]

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). Kansas fully insured plans are held to the Insurance Department's utilization-management standards adopted by K.A.R. 40-4-41: prospective (pre-service) review "Within 15 calendar days of the receipt of request" (one 15-calendar-day extension, with at least 45 days to supply missing information) and "no later than 72 hours" for urgent care; an urgent request to extend a current course of treatment is decided within 24 hours if received "at least 24 hours before the expiration of the currently certified period." Self-funded ERISA plans land on the same numbers under 29 CFR 2560.503-1 (15 days, 72 hours urgent), so 15 calendar days / 72 hours from receipt is the ceiling either way. Where state law is stricter than UHC's 15 days, the law wins for fully insured members.^{[8][9][10][11]}

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." Kansas's COB rule (K.A.R. 40-4-34) governs fully insured plans: for a child whose parents are married or living together, "The plan of the parent whose birthday falls earlier in the calendar year is the primary plan" (same birthday: the plan that has covered the parent longest); 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][12][9][13][14][15][16]}

K.S.A. 40-2,194 limits the mandate to covered individuals under age 12, on fully-insured large-group coverage only (51+ employees since 2023's SB 24), with ABA capped at 1,300 hours a year for four years for a child diagnosed between birth and age 5 and 520 hours a year otherwise — caps a plan may exceed with prior approval when medically necessary. Advocacy analysis (not a regulator determination) treats the under-12 limit and the hour caps as unenforceable quantitative treatment limits under MHPAEA for parity-covered plans, so treat an age- or cap-based denial as appealable rather than final. The carrier's national ABA policy sets no age bound of its own. Optum's ABA State Mandates supplement does carry a Kansas section, but it is a "For Kansas Medicaid member" section governing UnitedHealthcare Community Plan of Kansas — it does not reach commercial members.^[3][1][2]

Ask the plan: Benefits verification on the specific plan — funding type first, then the ABA benefit terms.

Optum publishes no ABA telehealth code list in the Supplemental Clinical Criteria; it points providers to CASP's Practice Parameters for Telehealth-Implementation of Applied Behavior Analysis, Second Edition, which it describes as a resource for ABA "delivered via telehealth in a broad range of clinical settings (e.g., home, clinic, school)" and as a supplement to, not a replacement for, in-person delivery.^[1]

Ask the plan: Optum/UnitedHealthcare provider services and the plan's telehealth reimbursement policy — confirm which ABA codes are payable remotely and with which POS before scheduling.

Two numbers, from two documents. Clinically, "consistent with CASP standards of care, direct case supervision is required 1–2 hours for every 10 hours of direct treatment per week," with technicians under the supervision of a BCBA or licensed behavioral health clinician and parents discouraged from serving as their own child's RBT. On the claim side, the commercial reimbursement policy polices the boundary rather than a ratio: "CPT codes 97153 and 97155 may not be billed for technician training," and 97155 "should be reported only for services where the QHP is either engaged directly with the patient or is directing a technician in implementing a modified protocol with the patient" — treatment planning is indirect and not separately reimbursable.^[1][7]

Yes, with a single-provider exclusion. "Can I report 97153 or 97154 with 97155 concurrently? A. Yes, as long as the criteria in the descriptors of both codes are met. A single QHP may not report 97153 or 97154 with 97155 concurrently." So the concurrency has to be two people — technician on 97153, analyst on 97155 directing them with the patient present. Separately, 97155 and 97156 may both pay on the same date of service only if the services are separate, distinct and clearly documented in the progress notes.^[7]

Optum publishes its own per-day table on top of CMS MUEs — maximum frequency per day: 97151 32 units (8 hrs), 97152 16 (4 hrs), 97153 32 (8 hrs), 97154 18 (4.5 hrs), 97155 24 (6 hrs), 97156 16 (4 hrs), 97157 16 (4 hrs), 97158 16 (4 hrs), 0362T 16 (4 hrs), 0373T 32 (8 hrs). MUEs otherwise apply per CMS guidance, and billing above 32 units/day of 97153 "may be subject to non-reimbursement or recovery."^[7]

One provider-level modifier per line, matching whoever actually rendered the service: HM = Registered Behavior Technician (less than bachelor's level), HN = BCaBA (bachelor's level), HO = BCBA or master's-level licensed clinician, HP = BCBA-D or doctoral-level licensed clinician. A billable ABA-supervisor service is billed with the applicable CPT code plus HO. Stacking level modifiers is a denial risk: "Billing multiple provider-level modifiers (HN, HM, HO, HP) on the same service line same service and same DOS is not appropriate and may result in claim denial."^[7]

No POS code list is published. The clinical criteria draw the school line instead: ABA is not covered for "services that are not ABA therapy, such as 1:1 aid delivered simultaneously during classroom instruction, or services covered under the Individuals with Disabilities Education Act (IDEA)," while "school ABA services do allow for coordination of services and would cover services such as teacher training, meetings with school personnel, and observations in the school setting."^[1]

Ask the plan: UnitedHealthcare/Optum provider services and the member's benefit document.

No signature rule is published, but the documentation burden is explicit where money turns on it: services billed on the same date must be "separate, distinct, and clearly documented in the progress notes," and if documentation does not clearly separate them the claim may be denied. Who signs, and within what window, is not stated.^[7]
