UnitedHealthcare administers ABA through Optum Behavioral Health, with authorization running through the Provider Express portal as a two-step process — assessment first, then treatment. Optum's Supplemental Clinical Criteria are among the most operationally specific in the industry (down to utilization thresholds and code clusters), which cuts both ways: more rules to satisfy, but also more predictability for an intake team that knows them.
Step one authorizes the assessment: functional behavior assessment, caregiver interviews, direct observation, record review, baseline skills, and norm-referenced instruments. Step two authorizes treatment based on what the assessment produced. Both run through Provider Express. For most commercial plans without a state-specific carve-out, the standard Optum Supplemental Clinical Criteria (BH803ABASCC) apply.[1]
The diagnosis bar: DSM-5-TR ASD from a state-licensed physician, psychologist, or other qualified clinician, confirmed with at least one clinically validated tool (ADI-R, ADOS-2, DISCO — or second-level tools like CARS-2, RITA-T, STAT).[1]
Optum authorizes in four clusters: assessment (97151, 97152), direct care (97153, 97154), multi-staff (0362T, 0373T), and QHP services (97155–97158). Units can flex within a cluster without a new authorization — a genuinely useful operational buffer. Concurrent billing is allowed for supervision (97153+97155), group oversight (97154+97155), and parent training alongside direct care (97153+97156). Not covered: team meetings without the member, 1:1 classroom aides, and services owed under IDEA — which is why intake should capture the school/IEP picture precisely.[1]
Reviews land every 4–6 months and want progress documented per targeted behavior using the same measurement methods as baseline — mastered-program rates, change scores, updated standardized adaptive measures. Two operational tripwires matter for scheduling and intake: inadequate progress within 6 months requires documented reasons plus treatment modification, and utilization below 80% of authorized hours over a two-week window draws scrutiny. Families whose availability can't support the authorized intensity are a reauthorization risk from day one — capture real availability honestly at intake.[1][13][3]
Does Optum require graphs at reauthorization? No document we read asks for them. The Supplemental Clinical Criteria (interim review April 2026) ask for numbers measured the way the baseline was: “Progress is assessed and documented for each targeted symptom and behavior, including progress toward defined goals, including the same modes of measurement that were utilized for baseline measurement.” That 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.” Movement from baseline must be shown “using validated and norm referenced assessments of functioning,” with caregiver progress where it applies. Each review must also show how generalization is targeted, list the barriers and their fixes, and say which goals were modified or removed. Optum’s portal review guide (BH00705) asks, for each domain, for the main goals, the total number of goals and the “Progress made in this area including number of goals mastered.” Clinical updates are reviewed “ordinarily 6 months” apart and “should include all areas from the initial plan.” Optum’s CPT FAQ sets no fixed reassessment interval (“There is no required frequency at which an assessment must take place”). It asks for the continued-care request “no more than 30 days prior to the current approvals on file expiring.” Time spent on “data analysis, graphs” is not billed separately; it is bundled into 97151 or the direct-service codes.[1][13][3]
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 — not a replacement for — in-person care.[2]
Optum answers this directly. Its National Network Manual (effective Oct. 1, 2025) says: “Providers offering telehealth visits must be licensed in the state where the member is located at the time of service. In addition, providers must comply with all licensing laws and telehealth regulations in the jurisdiction(s) where the provider is licensed and where the member is receiving treatment. This includes specific telehealth documentation requirements, informed consent to treat via telehealth, and other telehealth-specific laws and regulations.” Providers also attest to offering telehealth to be listed for it in the directory. For ABA, check the BCBA’s licence against the state the child is in at the time of each session, not the state the agency is in.[7]
Only as an exception. The National Network Manual says: “On occasion, emergent or other unusual circumstances will interfere with the pre-authorization processes. In those cases, requests for a retrospective review of services must be submitted within 180 calendar days of the date(s) of service, unless otherwise mandated by state law.” A retrospective review covers an initial request “made after services have already been delivered but no claim has been filed.” The request “must include information regarding the reason or circumstances preventing required prior authorization or notification and include the medical record and will be processed at the sole discretion of Optum.” Optum decides within 30 calendar days of receipt, and requests outside the time frame “will not be processed.” Treat retro review as a safety valve, not a workflow.[7]
Payment time and codes: Optum’s National Network Manual says “Generally, claims that contain all required information and have the required authorization, if applicable, will be paid within 45 calendar days after Optum receives the claim, or as required by state and federal laws. This may exclude claims that require coordination of benefits determinations.” Bill the primary carrier first when the child has other coverage. No weekly submission cutoff is published. Optum’s commercial ABA reimbursement policy (2022RP501A, updated June 2026) covers “CPT codes 97151-97158 along with the appropriate modifier” for the credential that delivered the service. Indirect work has no separate code and is bundled into the direct codes. HCPCS H-codes are not on its commercial ABA code list.[7][4][3]
Fee schedule, taxonomy and EVV: Optum publishes no ABA rate table. Its CPT FAQ says contracted providers “should bill your contracted billing codes and customary charges as outlined on your Fee Schedule after receiving appropriate authorization,” and “You will be reimbursed based on your contracted rate.” The National Network Manual adds that “Failure to follow the terms and conditions as set forth on your fee schedule may result in claim denial(s).” The manual mentions taxonomy only as a directory field you can update. It says nothing about taxonomy on claims or about electronic visit verification. Ask Optum if your agreement requires either.[7][4][3]
Optum’s National Network Manual (effective Oct. 1, 2025): “All information necessary to process claims must be received by 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.” Late claims “may be rejected,” the member may not be billed for them, and corrections should be made “within 90 days of receipt of the initial claim.”[7][4][3]
Disputes on commercial plans run in two steps: reconsideration first, then appeal. “The 2-step process allows for a total of 12 months for submission for both steps,” unless state law or the participation agreement sets another deadline.[7][4][3]
Every ABA line carries a credential modifier under Optum’s reimbursement policy 2022RP501A: HM for an RBT, HN for a BCaBA, HO for a master’s-level BCBA or licensed clinician, HP for a BCBA-D. On joining the network, Optum’s ABA CPT FAQ says “Solo Behavior Analysts/Specialists and Group credentialing can take from 45 to 120 days after submission of all materials,” and a new agency audit “normally” takes up to 90 days to schedule.[7][4][3]
Not for ABA. Optum’s National Network Manual (effective September 1, 2026), which governs UnitedHealthcare behavioral health claims including ABA, lists what a Form 1500 claim should carry: member and subscriber names and dates of birth, member ID, ICD diagnosis, dates of service, length of session, type and duration of service, and the clinician’s name, credentials, tax ID and NPI. A referring provider is not on the list. UnitedHealthcare’s 2026 Administrative Guide asks for a valid billing NPI, rendering NPI and taxonomy on all claims and adds “we encourage you to submit the referring health care provider’s NPI”; it makes the referring provider’s name and NPI mandatory only on “laboratory, DME, imaging and home health claims.”[16][8]
The clinical policy above is national, but three state-level layers change what a family's card actually buys: the state autism mandate (what fully-insured plans must cover), the carrier's state Medicaid plans (which follow the state Medicaid rules, not this commercial policy), and plan funding type (self-funded ERISA plans can carve benefits differently).

The questions that decide whether a family can start with UnitedHealthcare / Optum, and what they have to bring. Each maps onto something intake should ask on the first call.
A DSM-5-TR autism spectrum diagnosis from a state-licensed physician, psychologist, or other qualified clinician. The credential is submission data, not background: Optum asks for the diagnosing clinician and the confirming instrument as part of the step-one assessment authorization on Provider Express.[1]
The strictest named-tool requirement among the national commercial carriers. 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; “diagnosed by Dr. X” with no named tool is the most common reason an Optum assessment request stalls at intake.[1]
No physician referral or order is required by the Supplemental Clinical Criteria. What stands in its place is a two-step authorization through the Provider Express portal: step one authorizes the assessment — functional behavior assessment, caregiver interviews, direct observation, record review, baseline skills and norm-referenced instruments — and step two authorizes treatment based on what the assessment produced. Both are required before the corresponding service. Where state law specifies otherwise, the state-specific criteria in Optum's ABA State Mandates supplement govern instead of the standard criteria.[1]
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.”[5][3][1]
The Supplemental Clinical Criteria publish no age limit for ABA. Where a state has its own entry in Optum's ABA State Mandates supplement, that entry can import a mandate's age terms for fully-insured business — Maryland's entry adopts the COMAR hour floors that run by age band — but on the national criteria age is a benefits question, decided by the plan and the state of issue.[1]
Ask the plan: Benefits verification on the specific plan, and Optum's ABA State Mandates supplemental criteria for the state of issue.
UnitedHealthcare's 2026 Administrative Guide says "We notify you of our coverage decision within the time required by law" and, for commercial prior authorization, lists "Standard requests: up to 15 calendar days" and "Expedited requests: 72 hours" (may be extended for missing information), asking for notification "at least 15 calendar days in advance, if possible," and at least 5 business days before the service. Fully insured plans can be tighter under state utilization-review law; self-funded plans follow ERISA (15 days pre-service, one 15-day extension; 72 hours urgent). For ABA the operative lead time is Optum's: request continued services "no more than 30 days prior to the current approvals on file expiring," with all clinical information ready at the call.[8][2][9]
Ask the plan: Benefits verification: fully insured (state UR deadlines) or self-funded/ASO (ERISA)? Confirm the continued-service window with the Optum ABA line (behavioral health number on the member card).
UnitedHealthcare: "COB is administered according to the member's benefit plan and in accordance with law." Optum puts the check on the provider — "You are responsible for determining if the member has other insurance coverage. If so, you should bill the primary insurance carrier first" — and when Optum is secondary "you will be paid up to the Optum contracted rate," with no billing the family for the difference. Neither document states the dependent-child order itself, so the birthday rule applies through state COB law on fully insured plans and through the plan document on self-funded ones. UnitedHealthcare pays ahead of Medicaid (payer of last resort by federal law — the Medicaid program may still require its own PA), TRICARE (secondary to other health insurance by law) and CHAMPVA (pays after other health insurance). To bill a secondary plan when the member has no ABA benefit, Optum's FAQ says to call the number on the card to request a denial.[8][7][2][10][11][12]
Ask the plan: Benefits verification: ask which COB order and secondary-payment method the plan document uses (standard vs maintenance of benefits), and whether the plan is fully insured or self-funded.
No recency rule for the ASD diagnosis is published in the Supplemental Clinical Criteria cited here. The cadence Optum does set is downstream: continued-service reviews land every 4–6 months (per account and state law) and require progress documented per targeted behavior using the same measurement methods as baseline, plus updated standardized adaptive measures. Inadequate progress within six months requires documented reasons and a treatment modification.[1]
Ask the plan: Optum provider services, or the step-one assessment-authorization request on Provider Express — ask whether an evaluation of this age will be accepted before scheduling.
Coverage decides whether UnitedHealthcare / Optum 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.
Optum publishes both a band and a floor: supervision at 1–2 hours per 10 hours of direct treatment, and a minimum of one hour of 97155 per case per month. The floor is the one that catches people — a light month still owes an hour of billed supervision. The Supplemental Clinical Criteria (interim review April 2026) put the band as “direct case supervision is required 1–2 hours for every 10 hours of direct treatment per week,” consistent with CASP. They set no cap on how many technicians or cases one BCBA may supervise. Technicians “should be registered behavior technicians (RBT) or another appropriately certified behavior technician as allowable by state mandate.”[1]
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.”[4][3]
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.[4][3][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.[3][6][4]
Optum's exclusions are the operative setting rule rather than a place-of-service table: team meetings without the member, 1:1 classroom aides, and any service owed under IDEA are not covered. That makes the school and IEP picture a coverage question rather than background — capture it precisely at intake, because a goal that belongs in the IEP is a goal Optum will not pay for.[1]
Optum names the rendering credential on every line but not whose NPI carries it. Its commercial ABA reimbursement policy (2022RP501A, updated June 2026): “The appropriate modifier must be billed to reflect the appropriate credentials of the provider delivering the services” — HM for an RBT (“less than a bachelor’s degree level”), HN for a BCaBA, HO for a master’s-level BCBA or licensed mental health provider, HP for a BCBA-D. Its ABA CPT FAQ adds that “Any ABA Supervisor who is credentialed under the group or facility contract can see a member,” and that BCaBAs bill “with the outlined modifiers under your group model.” Neither document says whether the technician’s or the supervisor’s NPI goes in the rendering field.[4][3]
Ask the plan: Optum provider services (877-614-0484) or your participation agreement — confirm the rendering-NPI convention for HM-modifier lines before the first claim.
Optum’s National Network Manual says complete, authorized claims are generally paid within 45 calendar days after Optum receives them, or faster where state or federal law requires. Claims that need a coordination-of-benefits determination may take longer. No weekly billing cutoff is published.
No graph is required. Optum wants progress on every target measured the same way as the baseline. That means rates and percentages of mastered programs and targets, change scores on outcome and skills-based measures, and updated standardized adaptive (norm-referenced) scores, plus caregiver progress. Reviews ordinarily come every 6 months. Submit the continued-care request no more than 30 days before the current authorization expires.
No. Optum’s National Network Manual lists the required claim fields for behavioral health claims without a referring provider, and UnitedHealthcare’s 2026 Administrative Guide only encourages the referring NPI. It is mandatory there only on lab, DME, imaging and home health claims.
Yes — a two-step process via Optum's Provider Express portal: an assessment authorization first, then a treatment authorization, generally under Optum's Supplemental Clinical Criteria unless state law specifies otherwise.
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.
Utilization below 80% of authorized hours over a two-week period draws scrutiny at review. Intake should capture realistic availability so the requested intensity matches what the family can actually attend.
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.
Only if licensed where the child is. Optum requires telehealth providers to be licensed in the state where the member is located at the time of service, and to follow the licensing and telehealth laws of both their own state and the member’s.
Only in emergent or unusual circumstances. A retrospective review must be requested within 180 calendar days of the service (unless state law says otherwise), must explain why prior authorization was not obtained, and is at Optum’s sole discretion. Optum decides within 30 calendar days.
90 calendar days from the date of service under Optum’s National Network Manual, unless state or federal law or the member’s plan allows longer. Corrections should be made within 90 days of the original claim.
Twelve months in total for both steps (reconsideration, then appeal) on commercial plans, unless state law or your participation agreement sets a different deadline.
Optum’s ABA CPT FAQ says 45 to 120 days after all materials are submitted, for solo analysts and groups alike. New agencies also need a site audit, which can take up to 90 days to schedule.
