UnitedHealthcare runs ABA through Optum Behavioral Health, under Optum’s ABA Supplemental Clinical Criteria. We checked Optum’s State Mandates supplement (effective July 2026). It has entries for Arizona, California, Connecticut, Florida, Indiana, Massachusetts, New Jersey, Ohio, Pennsylvania and Virginia, but none for Idaho, so the national criteria apply unchanged. Idaho has no Medicaid managed-care plan that handles ABA, so in Idaho a UnitedHealthcare card for a child is a commercial card.
Optum’s criteria state that "Prior authorization is required for ABA (unless otherwise specified or mandated by contract or law)." The Provider Express ABA page has providers "Request ABA assessment and treatment authorizations" in the portal, choosing "ABA Assessment or Treatment" for each request. The diagnosis must come from "a state licensed physician, psychologist, or other state licensed clinician" and be confirmed "using at least one clinically validated tool." Direct case supervision "is required 1–2 hours for every 10 hours of direct" treatment. Continued-service review looks specifically at utilization below 80% of authorized hours over a two-week period. Services covered under IDEA, or a 1:1 aide during classroom instruction, are excluded.[4][6][5]
Idaho is one of the few states with no autism insurance statute, and intake should say so plainly. What Idaho has instead is Department of Insurance Bulletin No. 18-02 (April 2, 2018). Reading the federal Mental Health Parity and Addiction Equity Act, ACA § 1557 and the state’s Essential Health Benefits together, the Department declared that it "will consider an exclusion of treatments for autism spectrum disorder as discriminatory and prohibited when a plan includes coverage of rehabilitative or habilitative services, such as coverage of occupational therapy or speech therapy." It applies to the individual, small-group and large-group insured markets, and to self-funded plans subject to Idaho Code title 41, chapters 40 or 41, for plan years starting on or after January 1, 2019. Covered treatment must be "consistent with other mental health services (including applicable deductibles, copayments, or coinsurance), not subject to any separate dollar limits or visit limits, and in parity with medical and surgical benefits." The bulletin defines treatment as "evidence-based care and related equipment prescribed or ordered for an individual diagnosed with an autism spectrum disorder by a licensed physician or a licensed psychologist who determines the care to be medically necessary, including but not limited to behavioral health treatment" — it does not name ABA by name, and it sets no age limit. Carriers may still review medical necessity and "periodically review the medical necessity of continuing" treatment. Two practical limits: a bulletin is weaker than a statute, and a self-funded employer plan the Department does not regulate (most ERISA plans) sits outside it entirely — plan funding type is the first fact to establish.[7]
Idaho has no behavior-analyst licensure law and is not on the BACB’s list of licensing states, so Optum’s "Master- or Doctoral-level provider that is a Board-Certified Behavior Analyst" is the Idaho path. UnitedHealthcare publishes no commercial ABA rates, and they are negotiated in your agreement.[8][4]
UnitedHealthcare’s ABA benefit is managed by Optum Behavioral Health, whose National Network Manual (effective September 1, 2026) requires everything needed to process a claim to reach Optum “no more than 90 calendar days from the date of service, or as allowed by state or federal law or the member’s specific benefit plan,” with corrections within 90 days of first receipt. Clean, authorized claims are “generally” paid within 45 calendar days of receipt or as state or federal law requires. Disputes run in two steps — reconsideration, then appeal — with 12 months in total for both unless state law or your participation agreement sets a different deadline.[13][3][19]
Optum’s National Network Manual (effective September 1, 2026) also sets the payment clock: claims with all required information and any required authorization "will be paid within 45 calendar days after Optum receives the claim, or as required by state and federal laws," which may exclude claims needing a coordination-of-benefits determination, and when Optum is secondary it pays up to the Optum contracted rate. UnitedHealthcare’s 2026 administrative guide adds that a corrected claim (frequency code 7, with the original claim number) must arrive within the same timely-filing limit as the original. No weekly payment cycle or submission cutoff is published.[13][3][19]
Which codes: Optum’s commercial ABA reimbursement policy (2022RP501A, updated June 2026) lists the reimbursable codes for the commercial ABA program as 97151–97158, 0362T and 0373T, each in 15-minute units; 97151–97158 carry a credential modifier (HM, HN, HO or HP), while 0362T and 0373T are listed as "Additional Autism/Applied Behavior Analysis Codes that do not require modifiers"; no HCPCS H-code (H0031, H0032, H2014, H2019) is on that list.[13][3][19]
Idaho’s prompt-pay clock depends on how fast the provider files. Under Idaho Code § 41-5602, if an electronic claim is submitted within thirty days of the date of service, the insurer “shall pay or deny the claim not later than thirty (30) days after receipt”; a paper claim submitted within forty-five days of service must be paid or denied within forty-five days. A denial or request for more information must be sent in writing within the same thirty or forty-five days and must describe everything needed, after which the insurer has thirty days from receiving it. Late claims accrue interest at the statutory contract rate (§ 41-5603). The time limits do not apply where the insurer is complying with a provider contract that sets different payment terms (§ 41-5605(3)). These statutes bind fully insured plans issued in the state; a self-funded employer plan (ERISA) is not subject to them and follows its plan documents and your contract.[16][17][18]
Not for ABA. Optum, which manages UnitedHealthcare’s behavioral benefit, says in its National Network Manual (effective September 1, 2026) that a claim must carry the coding (ICD diagnosis, CPT/HCPCS and modifiers), the member ID number, customary charges, and the provider’s TIN and NPI. Paper Form 1500 claims add the member and subscriber names and dates of birth, the length of session, the type and duration of service, and the clinician’s name, credentials, Tax ID and NPI. A referring provider is not on either list.[19][3]
UnitedHealthcare’s 2026 administrative guide requires the referring provider’s name and NPI only on laboratory, DME, imaging and home health claims. For every other claim, it requires “a valid billing NPI, rendering NPI and relevant taxonomy code(s)” and says “we encourage you to submit the referring health care provider’s NPI.” In short, the referring NPI is optional on an ABA claim, and leaving it off is not a denial reason under either document.[19][3]
Optum’s ABA Supplemental Clinical Criteria (interim review April 2026) say that "With each clinical review for continued ABA treatment, the provider must submit updated documentation" showing progress "for each targeted symptom and behavior, including progress toward defined goals, including the same modes of measurement that were utilized for baseline measurement." Progress "should include rate and percentage of mastered programs, rates of mastered targets, change scores for any outcome measures, updated standardized adaptive measures, and change scores for skills-based assessments," with movement from baseline shown on validated, norm-referenced assessments and, where applicable, the caregiver’s own progress. Inadequate progress over six months calls for an analysis of the reasons and modified interventions, and the review looks at use below 80 percent of authorized hours over two weeks. The criteria do not require graphs as such.[4]
Single case agreements: Optum's ABA FAQ says an SCA during credentialing is granted "Not automatically. In exception cases, based on clinical need, new business implementations, or other gaps in the network, a SCA may be approved after review with the clinical team." Once an SCA provider becomes contracted, it sends its current member list to its Network Manager to have the authorizations updated. Out-of-network providers bill on the standard Form 1500.[12][19][13]
Joining the network: Optum lists its ABA contracting criteria (a BCBA with state licensure where the state licenses behavior analysts, six months of supervised ABA experience, $1 million/$1 million professional liability for an individual; $1 million/$3 million plus general or supplemental liability for a group). Credentialing "can take from 45 to 120 days after submission of all materials," and every new ABA agency needs an Optum site audit that "can take up to 90 days to schedule." None of these Optum documents says the ABA network is closed to new providers.[12][19][13]
Whose authorization it is: when an agency is credentialed, "their affiliated clinicians are not credentialed but are considered participating under the agency's Participation Agreement," but "Any claims submission for a rendering clinician who has not been added to the network is subject to denial." Approvals are issued in code clusters (assessment 97151/97152; direct care 97153/97154; multi-staff 0362T/0373T; QHP services 97155–97158) and units "can shift" within a cluster. Optum publishes no rule on moving an authorization from one agency to another; "All services require prior approval," so a new agency calls the ABA team for its own approval.[12][19][13]
Credential modifiers (commercial ABA program): HM = RBT (less than a bachelor's), HN = BCaBA (bachelor's), HO = master's-level BCBA or licensed mental health provider, HP = BCBA-D or doctoral-level licensee; one provider-level modifier per line. 0362T and 0373T are listed as codes "that do not require modifiers."[12][19][13]
Disputes: network providers follow a 2-step process — Step 1 reconsideration, Step 2 appeal — with "a total of 12 months for submission for both steps" unless state law or the Participation Agreement sets another deadline. Send "member-specific treatment plans, clinical records, payment appendices or other items that support why you believe our decision was incorrect," plus proof the claim was filed on time; mail to Optum Behavioral Health Solutions, P.O. Box 30757, Salt Lake City, UT 84123, or use Provider Express. Non-urgent clinical appeals have a 180-day window.[12][19][13]
The questions that decide whether a family can start with UnitedHealthcare / Optum in Idaho, and what they have to bring. Each maps onto something intake should ask on the first call.
No expiry on the diagnosis. The DSM-5-TR diagnosis and severity level must be confirmed and documented with a validated tool, and review clocks run on progress: lack of progress within 6 months triggers reassessment and plan changes.[4]
"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." LCSW: yes under Optum's test — Idaho's board rule puts "assessment, diagnosis, and treatment of mental, emotional, and behavioral disorders" inside clinical social work (IDAPA 24.14.01.200.03).[4][20]
At least one clinically validated tool, from a non-exhaustive three-tier list. First-level screens: ABC, CHAT/M-CHAT, CSBS-DP-IT, ASQ, AQ, CAST. Second-level: CARS/CARS-2, RITA-T, STAT. Formal diagnostic tools: ADI-R, ADOS/ADOS-2, DISCO.[4]
The SCC require prior authorization, not a separate referral. For Idaho state-regulated plans, Bulletin 18-02 frames covered treatment as care "prescribed or ordered" by a licensed physician or licensed psychologist, so get a written prescription.[4][7]
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, and neither is the 97151 assessment or the technician-assisted 97152: plan the assessment in person. 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.”[14][12][4]
The SCC carry no age criterion, and coverage turns on the member’s benefit plan. Bulletin 18-02 sets no age limit for state-regulated plans, and self-funded plans may carry their own terms.[4][7]
Ask the plan: Provider Express benefits check or the behavioral health number on the member card — establish fully insured vs. self-funded first.
Turns on how the plan is funded. Idaho’s Managed Care Reform Act requires a managed care organization to answer a nonemergency prior-authorization request "within two (2) business days after complete member medical information is provided," "unless exceptional circumstances warrant a longer period" (Idaho Code § 41-3930). Self-funded ERISA plans follow 29 CFR 2560.503-1: 15 days, one 15-day extension, and 72 hours for urgent claims.[9][10]
Ask the plan: At benefits verification ask whether the plan is fully insured or self-funded, then confirm Optum’s turnaround and continuation lead time (Provider Express support 1-866-209-9320).
For a child on two parents’ plans, Idaho’s rule (IDAPA 18.04.14.022) makes "the plan of the parent whose birthday falls earlier in the calendar year" primary, with separate rules for divorced or separated parents. Self-funded plans follow their own documents. If the child also has Idaho Medicaid, this plan pays first because Medicaid is the payer of last resort, and Medicaid pays CHIS on H-codes. TRICARE pays after this plan (10 U.S.C. 1079(i)(1)), and CHAMPVA is the last payer (38 CFR 17.270).[11][21][22][23]
Ask the plan: Ask UnitedHealthcare/Optum at benefits verification for the coordination-of-benefits order on file, and record every other coverage the child has.
Coverage decides whether UnitedHealthcare / Optum in Idaho pays. These decide whether the claim survives: how sessions must be staffed and supervised, what may be billed concurrently, the per-day ceilings, who signs the note, where the service is payable, and whose NPI the claim goes out under.
Consistent with CASP standards of care, "direct case supervision is required 1–2 hours for every 10 hours of direct" treatment. Technicians must be under the supervision of a BCBA or licensed behavioral health clinician and should be RBTs or another appropriately certified technician. Optum does not recommend that parents serve as RBTs for their own child.[4]
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.”[13][12]
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. Bulletin 18-02 bars separate dollar or visit limits on state-regulated plans.[13][12][4][7]
“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.[12][15][13]
ABA is provided "at the least restrictive and most clinically appropriate level." Not covered: "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)." School ABA does cover coordination, teacher training, meetings with school staff and observation in the school setting.[4]
Once the diagnosis is confirmed, a credentialed ABA provider is identified: a master’s- or doctoral-level BCBA, or a licensed behavioral health clinician credentialed for ABA. A BCaBA or non-licensed individual works under the direct supervision of that BCBA or clinician, who "takes responsibility for the individual’s care."[4]
Only two ABA codes change. From Dec. 1, 2026, UnitedHealthcare no longer requires prior authorization for 0362T and 0373T when provided to members younger than 18 on its commercial plans (commercial code list revised Nov. 6, 2026). 97151–97158 are not on the list and still need authorization, and the Individual Exchange and Community Plan lists name no ABA code. UHC says to check plan-specific exceptions in the Prior Authorization and Advance Notification tool. 0362T and 0373T are deleted from CPT on Jan. 1, 2027, so the change covers December 2026 dates of service.
Not automatically. Optum's ABA FAQ says an SCA may be approved "In exception cases, based on clinical need, new business implementations, or other gaps in the network" after review with the clinical team. Credentialing takes 45 to 120 days, and new agencies also need a site audit.
Optum’s criteria require updated progress data in the same measures used at baseline (mastery rates, change scores, updated standardized adaptive measures) at every continued review; they do not require graphs as such.
Optum’s commercial ABA reimbursement policy lists only CPT 97151–97158, 0362T and 0373T as reimbursable ABA codes, each with a credential modifier; no H-code (H0031, H0032, H2014, H2019) is on the list.
Yes, for ASD under Optum’s ABA Supplemental Clinical Criteria. Optum’s State Mandates supplement has no Idaho entry, so the national criteria apply. On state-regulated plans Idaho’s Bulletin 18-02 also bars autism-treatment exclusions.
Yes. In Provider Express, ABA assessment and ABA treatment are requested as separate authorizations.
No. Idaho Medicaid has no managed-care plan for children’s ABA. It is fee-for-service CHIS through the state, so a UnitedHealthcare card on an Idaho child is a commercial or employer plan.
Optum, which manages UnitedHealthcare’s behavioral health benefits, says “At a minimum, most treatment reviews are required every 4-6 months depending on the account/state law.” Call in the continued-care request “no more than 30 days prior to the current approvals on file expiring,” with updated progress data measured the same way as baseline and updated standardized measures. There is no fixed reassessment frequency (“There is no required frequency at which an assessment must take place”) — ask for reassessment hours inside the treatment request. If more hours are needed mid-authorization, call the ABA team with a clinical rationale.
Optum's ABA criteria say technicians "should be registered behavior technicians (RBT) or another appropriately certified behavior technician as allowable by state mandate," working under BCBA or licensed-clinician supervision. They also advise against a parent serving as the RBT for their own child.
No, not on commercial plans. Optum's telehealth billing guide allows only 97155, 97156 and 97157 by telehealth for ABA, so 97151 and 97152 are delivered in person. Supervision (97155) and caregiver training can be remote once the provider has completed Optum's virtual-visits attestation.
Optum Behavioral Health, which manages UnitedHealthcare’s ABA benefit, requires claims within 90 calendar days of the date of service unless state or federal law or the member’s plan allows longer (National Network Manual, effective September 1, 2026).
Idaho law (Idaho Code § 41-5602) requires a fully insured plan to pay or deny an electronic claim within 30 days of receipt (45 for paper) — but only when the claim was filed within 30 days of the service (45 for paper), and a contract with different payment terms overrides it. Self-funded employer plans are not bound by the statute.
No. Optum’s claim requirements do not include a referring provider. UnitedHealthcare makes the referring name and NPI mandatory only for lab, DME, imaging and home health claims. For other claims it encourages the referring NPI but does not require it.
