UnitedHealthcare Community Plan of Arizona runs its ABA benefit through Optum, with a dedicated AZ AHCCCS ABA Program on Provider Express — an Arizona-specific orientation, treatment request form, and quick reference guide, staffed by a dedicated Arizona autism clinical team. Like Mercy Care, it covers both Arizona funnels: it is an ACC plan and one of the two statewide DDD Health Plans ("DD by UHCCP"), plus an ALTCS contractor. The clinical posture matches the state baseline — no PA on assessment, no autism diagnosis required — but the paperwork is Optum-national in flavor, with Arizona-specific forms and a demanding treatment-request documentation list.
Assessments (97151/97152) start without authorization; every other ABA code requires PA, submitted through the online ABA Treatment Form on Provider Express or by fax to 1-888-541-6691. The treatment request is where Optum's rigor lives — it must include baseline and mastery criteria, a transition plan, discharge criteria, a behavior-reduction/crisis plan, parent goals, and supervision hours, and goals must not be educational or academic in nature. Concurrent reviews weigh progress and medical necessity under Optum's Autism/ABA clinical policy, run by a dedicated Arizona autism team of licensed clinicians and BCBAs. The plan's fee schedule mirrors the AHCCCS structure — 9715x plus 0362T/0373T in 15-minute units with credential modifiers — though dollar amounts aren't published in the orientation. Note the operational split: authorizations live on Provider Express, claims on UHCprovider.com (payer ID 03432), with a 90-day filing deadline.[1]
The orientation is explicit that UHC Community Plan is "the selected managed care administrator for Arizona AHCCCS Complete Care and AZ DD membership" — DD member cards say "DDD Health Plan by UHCCP" and carry Group AZDDD, versus AZHCCCS for ACC members. Same forms and rules, but confirm which book the member is in, since the DDD path comes with a different eligibility gate and bundled HCBS services. Registration mechanics that block claims if missed: the agency must be enrolled as AHCCCS provider type 77, BCBAs must be individually AHCCCS-registered, and the rendering provider's NPI (the BCBA or licensed clinician) goes in box 24J. And the diagnosis rule worth quoting in any dx-gate dispute: "ASD diagnosis is not required for ABA services for Arizona Medicaid members." Like the other big plans, UHC terminated Action Behavior Centers in the March 2026 network purge — expect displaced families.[1][4]
The questions that decide whether a family can start with UnitedHealthcare Community Plan of Arizona, and what they have to bring. Each maps onto something intake should ask on the first call.
Optum's Arizona eligibility list is membership-based, not age-based: the member must be covered under AHCCCS (Arizona Complete Care or the Developmentally Disabled program) and "diagnosed with a condition for which ABA-based therapy services are recognized as therapeutically appropriate, including autism spectrum disorder, by a qualified health care professional." No upper or lower age bound is published, and AMPM 320-S sets none either.[1][3]
None published. Neither Optum's Arizona orientation nor AMPM 320-S puts a clock on the diagnostic evaluation; each clinical review instead asks for "confirmation member has an appropriate DSM-5 diagnosis that can benefit from ABA," current medications, concurrent services and school hours.[1][3]
"Diagnosed with a condition for which ABA-based therapy services are recognized as therapeutically appropriate, including autism spectrum disorder, by a qualified health care professional. ASD diagnosis is not required for ABA services for Arizona Medicaid members." That last sentence is the one to quote in any diagnosis-gate dispute.[1]
Optum's Arizona orientation names no required instrument — it asks each review to confirm an appropriate DSM-5 diagnosis. The instrument standard is the state's: AMPM 320-S requires assessments using standardized and/or non-standardized instruments through both direct and indirect methods, naming the PDDBI, the Brigance Inventory of Early Development and the Vineland Adaptive Behavior Scales as standardized examples.[1][3]
No physician referral is required; the gate is authorization. "All ABA services require prior authorization except 97151 and 97152" — assessment requests go through the online ABA Treatment Form on Provider Express, treatment requests through the same form or fax 1-888-541-6691. The treatment request must carry baseline and mastery criteria, a transition plan, discharge criteria, a behavior-reduction/crisis plan, parent goals, supervision and treatment-planning hours, relevant psychological information and coordination of care, and goals "must not be educational or academic in nature."[1]
UHC Community Plan of Arizona’s 2026 manual: "A decision and notification is made no later than 14 calendar days following the receipt of the request. This time frame may be extended up to 7 days" on request; expedited no later than 72 hours (extendable up to 14 days). Optum administers ABA — all ABA codes except 97151 and 97152 need PA, with the same clinical packet at each concurrent review — and publishes no ABA clock or reauth lead time. AHCCCS’s own CY2025 prior-authorization metrics report (March 2026) says that "Beginning January 1, 2026" the CMS rule requires Medicaid managed care plans to decide within "7 calendar days for standard requests (non-urgent)" and "72 hours for expedited requests (urgent)"; the federal regulation ties the 7-day ceiling to rating periods starting on or after January 1, 2026. Confirm with UHC which clock it runs.[5][1][6][7]
UHC is payer of last resort and "will reimburse as secondary payer without prior authorization when the claim is submitted with an EOB showing primary allowed. If an authorization is denied by the Primary Insurer, providers are to submit the request" to UHC with clinical documentation. Secondary claims "must be received within 6 months (180 days) from the date of service, even if the primary carrier has not made payment." Payment is the difference up to the contracted rate. The manual lists no pay-and-chase services of its own; AHCCCS policy (ACOM 434), which it follows, requires pay-and-recover for preventive pediatric/EPSDT services and bars a secondary PA when the other insurer approved the service. Under federal rules TRICARE pays before Medicaid, and CHAMPVA pays first when the child is also Medicaid-eligible.[5][8][9][10]
Not published. Optum's Arizona AHCCCS ABA orientation covers eligibility, authorization, documentation, coding and claims but says nothing about telehealth delivery of the ABA codes; AMPM 320-S permits telehealth as a treatment-plan modality without naming payable codes.[1][3]

Coverage decides whether UnitedHealthcare Community Plan of Arizona 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.
Credentialing conditions rather than a ratio. For ABA/IBT groups Optum requires that "Behavior Technicians receive appropriate training and supervision by BCBAs or licensed clinician," that a "BCBA or licensed clinician on staff [provides] program oversight," and that a "BCBA or licensed clinician performs skills assessments and provides direct supervision of behavior technicians in joint sessions with client and family." Supervision hours must be itemised in the treatment request. No percentage or caseload cap is published, and AMPM 320-S sets none — so the BACB floor governs RBT-credentialed staff.[1][3]
The supervisor carries the claim. "The rendering provider's 10-digit NPI is required in box 24J and must be an active AHCCCS registered provider (The rendering provider is the BCBA/Licensed Clinician)," and "Field 31 must have a rendering provider name. Rendering supervisor (BCBA/Licensed Clinician) will bill for all services by them or the BCaBAs/RBTs under the supervisory protocol." The agency must hold an AHCCCS registration number as provider type 77, BCBAs must be individually AHCCCS-registered, claims go on a Form 1500 to payer ID 03432, and when a provider is contracted as a group the payment is made to the group, not the individual.[1]
Not addressed directly. The orientation's only concurrency rule is a pointer: "Providers are responsible for billing in accordance with nationally recognized CMS Correct Coding Initiative (CCI) standards," which is where the 97153/97155 same-time question is actually settled.[1]
Blocked on: Optum provider services / the Arizona autism clinical team, and the CMS NCCI edits Optum says it follows.
No per-day unit ceiling is published for the Arizona Medicaid program; Optum points to CMS Correct Coding Initiative standards and enforces the authorization instead — "units exceed authorization" is one of the named coding reasons claims get denied, alongside missing unit counts.[1]
Ask the plan: Optum provider services; confirm authorized units per code before scheduling.
No session-note signature rule is published in the Arizona orientation. What it does require at intake is a signed consent for billing using protected health information "including signature on file," informed consent for services, and a signed and dated Release of Information for each party granted access to PHI, with any refusal noted in the treatment record.[1]

No payable-setting list is published. The orientation treats setting as a coding input — "Place of service (home or clinic)" is one of the factors that determines which code and rate applies — and AMPM 320-S requires the treatment plan to specify the settings in which services will be delivered.[1][3]
Blocked on: Optum provider services for school- and community-based delivery, and the AHCCCS Behavioral Health Services Billing Matrix for covered settings.
Yes — through Optum's AZ AHCCCS ABA Program. Assessment codes 97151/97152 need no PA; all other ABA codes require authorization via Provider Express or fax, with a detailed treatment-request documentation list.
No — Optum's Arizona orientation states verbatim that an ASD diagnosis is not required for ABA services for Arizona Medicaid members. Medical necessity, supported by assessment, governs.
