UnitedHealthcare / Optum ABA coverage in North Carolina: 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 North Carolina plan the state mandate adds an ordering requirement the carrier policies do not: adaptive behavior treatment must be ordered by a licensed physician or licensed psychologist. The mandate does not reach non-grandfathered individual and small-group plans, and self-funded ERISA plans sit outside state insurance law entirely — establish plan funding type before relying on it.^[1][2]

Three codes, after an attestation. Optum’s Telehealth Billing guide (updated September 2025) is explicit for commercial plans: “For ABA services, telehealth is only allowed for these 3 CPT codes: 97155, 97156 or 97157” — virtual supervision of technicians and family training — so technician-delivered 97153 is not payable by telehealth. The provider must first be “an approved Optum virtual visits provider who has attested” (the virtual-visits attestation on Provider Express) and must tell the ABA Care Advocate at authorization. Bill the in-person code with the member’s location as the place of service: POS 10 when the member is at home, POS 02 anywhere else (the older ABA CPT FAQ says POS 02; the 2025 guide requires one of the two on every behavioral-health telehealth claim, and POS 11 or a telehealth modifier alone is not paid). Optum’s criteria add that telehealth is “not intended to supplant in-person service.” For assessments, that list matters: 97151 and 97152 are not among the three telehealth codes, so Optum’s guide gives no telehealth path for the initial assessment or a reassessment on commercial plans. BCBA supervision of the technician (97155) is one of the three, as is caregiver training (97156, 97157).^[7][5][1]

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. North Carolina’s mandate permits coverage to be limited to individuals 18 or younger and capped at $40,000 a year (CPI-indexed from 2017) on fully insured plans — quantitative treatment limits of doubtful enforceability against large-group plans under MHPAEA. The mandate does not apply to non-grandfathered individual and small-group plans, and self-funded ERISA plans are exempt by preemption.^[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.

UHC’s 2026 commercial administrative guide says standard requests take "up to 15 calendar days" and expedited "72 hours", and asks for requests "at least 15 calendar days in advance, if possible, but must be submitted at least 5 business days before the planned service date"; ABA itself is authorized by Optum Behavioral Health, whose network manual publishes no prospective decision clock (retrospective requests are decided within 30 calendar days). So the governing clock depends on funding. For a fully insured plan issued in North Carolina, G.S. 58-50-61(f) governs: "Prospective and concurrent determinations shall be communicated to the covered person's provider within three business days after the insurer obtains all necessary information" — the clock starts on complete information, not receipt, and the statute sets no separate faster clock for an urgent first decision (its expedited track is for appeals). In concurrent review "the insurer shall remain liable for health care services until the covered person has been notified of the noncertification." A self-funded employer plan sits outside state law and follows ERISA: a non-urgent pre-service decision "not later than 15 days after receipt of the claim by the plan", extendable once by up to 15 days; an urgent one within 72 hours; the clock starts when the request is filed, whether or not it is complete; and an urgent request to extend an approved course is decided within 24 hours if made "at least 24 hours prior to the expiration" of the current authorization.^{[11][10][13][14]}

Ask the plan: At benefits verification, ask whether the plan is fully insured (a policy issued in the state) or a self-funded employer (ERISA) plan — that decides which clock applies — then ask the carrier’s behavioral health precert line its expected ABA turnaround and how early it wants the reauth.

North Carolina’s COB rule for insured group plans (11 NCAC 12 .0514) sets the order: the plan covering the person as employee or subscriber pays before the plan covering them as a dependent; for a child of parents not separated, "the benefits of the Health Plan of the parent whose birthday falls earlier in a year are determined before those of the Health Plan of the parent whose birthday falls later" (same birthday: the longer-running plan first); for separated or divorced parents the custodial parent’s plan pays first, then the custodial parent’s spouse’s, then the non-custodial parent’s, unless a court decree the plan knows of assigns responsibility; Medicaid is expressly outside that rule. Self-funded plans follow their own plan document. UHC says "COB is administered according to the member's benefit plan and in accordance with law"; Optum’s network manual tells providers to determine other coverage, "bill the primary insurance carrier first, then notify Optum of your findings," and says it applies industry-standard COB rules and state law. Government coverage sorts itself by federal rule: a commercial plan pays before TRICARE, which is secondary to every other health plan but "In any double coverage situation involving Medicaid, CHAMPUS is always the primary payer"; CHAMPVA "is the last payer to OHI"; and Medicaid pays after all of them (42 CFR 433.139), so a child with commercial plus Medicaid needs this plan’s authorization and EOB before Medicaid will pay.^{[15][11][10][16][17][18]}

Ask the plan: Collect both parents’ plans, dates of birth, and any custody decree at intake; confirm primary/secondary with each carrier’s COB unit (and whether the plan is self-funded) before the first claim.

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. Optum’s network manual and commercial ABA reimbursement policy publish no cap on the number of technicians one BCBA may supervise; the standard is hours of supervision per hours of treatment.^[1][6]

Yes, with a single-provider exclusion. Optum’s commercial ABA reimbursement policy: “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 overlap has to be two people — a technician on 97153 and an analyst on 97155 directing them with the patient present. Optum’s ABA CPT FAQ adds that 97153 and 97156 “may be billed concurrently” as separate services to different family members by different providers. 97155 and 97156 on the same date pay only if “separate, distinct, and clearly documented in the progress notes” — “A single provider can’t bill for both simultaneously.” Team meetings bill only as supervision with the member, supervisor and technician present, and “CPT codes 97153 and 97155 may not be billed for technician training.” ABA alongside speech, OT or PT: Optum publishes no same-clock-time rule for ABA with another therapy. Its supplemental clinical criteria say "ABA services do not duplicate the services provided to or available to the individual by other medical or behavioral services," and require documented coordination with other allied health providers ("occupational therapy, speech therapy, physical therapy and any other applicable providers") "to reduce the likelihood of unnecessary duplication of services"; Optum's ABA CPT FAQ adds that ABA providers should know the child's other therapies, how often they occur and their goals, with ongoing communication documented.^[6][5][1]

Optum’s commercial ABA reimbursement policy (2022RP501A, updated June 2026) sets a maximum frequency per day for every code: 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) — and “If a provider bills in excess of 32 units per day, claims may be subject to non-reimbursement or recovery.” The ABA CPT FAQ confirms “For our commercial ABA program MUE’s apply.” There is no weekly hour cap: hours are authorized on documented clinical need, approved units can be shifted among codes within a cluster, and utilization below 80% of authorized hours over a two-week period is addressed at review.^[6][5][1]

“Provider signature is required on progress notes. Parent/guardian signatures are not required on progress notes” (Optum ABA CPT FAQ). Each daily session note records place of service, start and stop time, who rendered the service, the specific service, who attended and the interventions. Optum’s ABA documentation protocol (June 1, 2026) requires the “signature of the rendering provider” and “Legible identity of the rendering provider with credentials,” and “The date of signature must reflect the date the note is finalized” — a note signed after the date of service must follow late-entry rules and show the date it was signed. Same-date services must be “separate, distinct, and clearly documented in the progress notes,” or the claim may be denied.^[5][8][6]

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]
