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.[6]
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." News reports in March 2026 (azfamily, 3/5/2026) named UnitedHealthcare among the plans ending contracts with Action Behavior Centers and Centria (UnitedHealthcare declined to comment), so expect displaced families.[6][9]
Arizona licenses the practice: “A person who wishes to practice as a behavior analyst must be licensed pursuant to this article” (A.R.S. § 32-2091.02, Board of Psychologist Examiners), and practicing unlicensed is a class 2 misdemeanor (§ 32-2091.12). Arizona is unusual in giving out-of-state clinicians a telehealth-only route: under A.R.S. § 36-3606 a health care provider “who is not licensed in this state may provide telehealth services to a person located in this state” after registering with the board that licenses the comparable profession, holding “a current, valid and unrestricted license to practice in another state that is substantially similar,” carrying malpractice coverage that includes Arizona telehealth, and following Arizona’s scope and standard-of-care rules. Behavior analysts are licensed under Title 32, chapter 19.1, which § 36-3601 includes in the definition of “health care provider.” A registered provider may not open an Arizona office (except within a multistate group that includes an Arizona-licensed provider) or see Arizona patients in person without an Arizona license. Fewer than ten telehealth encounters a year, or care in consultation with an Arizona-licensed provider who keeps ultimate authority, is exempt from registration.[11][12][13][14][8][15][5]
AHCCCS ties ABA to the Arizona license: AMPM Policy 320-S defines a Behavior Analyst as “A person who is licensed pursuant to A.R.S §32-2091,” and A.R.S. § 32-2091.14 directs AHCCCS to recognize “a behavior analyst who is licensed pursuant to this article” as a behavioral health professional eligible for reimbursement. A § 36-3606 telehealth registration is not that license, so for AHCCCS work plan on full Arizona licensure.[11][12][13][14][8][15][5]
UnitedHealthcare Community Plan’s Arizona manual (effective 7/9/2026) adds its own check on every authorization request: “All rendering care providers, facilities, and vendors must be actively registered with AHCCCS.”[11][12][13][14][8][15][5]
UHC Community Plan’s Arizona manual (effective 7/9/2026) says: “We do not approve retroactive authorizations for therapy services. This includes physical, occupational, and speech therapy.” ABA is not named in that sentence, so confirm with the plan whether it treats ABA as a therapy service. The manual’s decision table gives retrospective review “Within 30 calendar days of receiving all pertinent clinical information.”[5]
Six months to file, twelve to get it clean. A.R.S. § 36-2904(G) bars AHCCCS from paying a claim “initially submitted more than six months after the date of the service for which payment is claimed or after the date that eligibility is posted, whichever date is later,” or one not submitted as a clean claim within twelve months — and the same subsection applies the identical limits to the health plans that contract with AHCCCS, so UnitedHealthcare Community Plan cannot pay a claim outside those windows either. The FFS billing manual restates it: a claim first received inside six months has until twelve months from the date of service to reach clean-claim status or be adjusted, after which “AHCCCS is not liable for payment.”[16][17][5][4][18][19][20]
The plan’s own clock is shorter for network providers. UnitedHealthcare Community Plan’s Arizona care provider manual (2027 edition, posted October 2026): “Network care providers must submit the initial claims submission within 90 days from the date of service or based on their contracted timely filing terms”; non-participating providers have 180 days. Deadlines run from the claim end date of service or the date eligibility is posted, whichever is later. Corrected claims (resubmission code 7) are due “within 1 year from the date of service, or as otherwise stated in your Agreement.” Secondary claims are due within 180 days of the date of service “even if the primary carrier has not made payment,” and a claim denied for a missing primary EOB can be resubmitted with it within 365 days of the date of service. After a recoupment you have the greatest of 12 months from the date of service or 60 days from the adverse action.[16][17][5][4][18][19][20]
Payment. The manual says to “Allow up to 30 days for UnitedHealthcare Community Plan to receive payment for initial claims and 45 days to receive adjustment requests.” AHCCCS ACOM 203 binds the plan “unless a subcontract specifies otherwise”: 95% of clean claims adjudicated within 30 days of receipt and 99% within 60, with interest at 10% a year from the 46th day on a non-hospital clean claim paid after 45 days. No weekly submission cutoff or check-run day is published.[16][17][5][4][18][19][20]
Disputes. AHCCCS requires claim disputes in writing within twelve months of the date of service, twelve months of the date eligibility is posted, or sixty days after the denial of a timely claim, whichever is later (A.R.S. § 36-2903.01(B)(4); A.A.C. R9-34-401 et seq.). Disputes for fee-for-service members go to AHCCCS’s Office of General Counsel (or through the AHCCCS Solutions Center); for UnitedHealthcare Community Plan members the dispute is filed with UnitedHealthcare Community Plan. An unfavourable Notice of Decision can be taken to a state fair hearing within 30 days of receipt.[16][17][5][4][18][19][20]
EVV. AMPM 540 (revised effective 08/06/26) applies Electronic Visit Verification to “personal care and home health services” under 42 U.S.C. 1396b(l), for ACC, DDD and fee-for-service alike, and AHCCCS’s EVV page names those services as attendant care, personal care, homemaker, habilitation, respite and in-home skilled nursing. ABA is not among them. A visit is subject to EVV only when the provider type, the service code and the place of service all match AHCCCS’s published list, so an agency that also bills habilitation in the home should check that list.[16][17][5][4][18][19][20]
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.[6][8]
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.[6][8]
"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.[6]
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.[6][8]
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."[6]
The plan’s Arizona manual refers telehealth questions to “The AHCCCS and Telehealth Services Policy 320-I,” and Optum’s Arizona ABA orientation adds no telehealth rule, so the rule is the AHCCCS rule: AMPM 320-I binds ACC, ALTCS and DDD Contractors by its own terms. All eight ABA CPT codes (97151–97158) are on the AHCCCS Telehealth Code Set (sheet effective 06/01/2026) for interactive audio-video with the GT modifier; none carries the audio-only FQ modifier, and 0362T and 0373T are not listed. The place of service on the claim is the originating site, where the member is (12 home, 03 school, 11 office): “AHCCCS will not be utilizing POS 02 and POS 10 for telehealth” unless another primary payer requires them. AMPM 320-S requires the treatment plan to “identify the modality by which the service will be delivered (whether in person or via telehealth, or in-group or individual setting, or combination thereof),” so name telehealth in the plan you submit for authorization.[3][2][8][5]
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][6][22][23]
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][24][25][26]
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.[6][8]
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.[6]
No per-day unit ceiling is published for the Arizona Medicaid program, but daily-frequency edits exist. Optum points to CMS Correct Coding Initiative standards and enforces the authorization — “units exceed authorization” is one of the named coding reasons claims get denied, alongside missing unit counts — and the plan’s Arizona manual says: “If you must exceed the maximum daily frequency for a procedure, submit the medical records justifying medical necessity.” The maxima themselves are not printed; the public Medicaid MUE for 97153 is 32 units per claim line.[6][5][1]
Ask the plan: Optum provider services; confirm authorized units per code before scheduling, and ask which daily frequency limit applies to 97153.
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.[6]
Blocked on: Optum provider services / the Arizona autism clinical team, and the CMS NCCI edits Optum says it follows.
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.[6]
Blocked on: The UnitedHealthcare Community Plan of Arizona / Optum provider manual and your participation agreement.
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.[6][8]
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.
The online ABA Treatment Form on providerexpress.com, or fax 1-888-541-6691. Claims go separately through UHCprovider.com (payer ID 03432) within 90 days of the date of service.
There is no public plan fee schedule. AHCCCS says its fixed ABA rates (effective November 1, 2023) apply only to fee-for-service programs and have “no impact on the contracts that AHCCCS health plans negotiate with their providers”: “MCOs and providers may negotiate any contracted rate that is agreed to by both parties.” Your rate is in your contract with UnitedHealthcare Community Plan; the AHCCCS fee-for-service schedule does not bind the plan.
Arizona requires a license (A.R.S. § 32-2091.02) but lets an out-of-state provider deliver telehealth after registering under A.R.S. § 36-3606. AHCCCS defines a Behavior Analyst as one licensed under A.R.S. § 32-2091, so plan on an Arizona license for Medicaid work.
Plan on no. UHC does not approve retroactive authorizations for therapy services (it names PT, OT and speech); ask whether it applies that to ABA before treating without approval.
Six months from the date of service (or from the date eligibility is posted, if later), and twelve months to reach clean-claim status. A.R.S. § 36-2904(G) sets those outer limits for every AHCCCS plan, but UnitedHealthcare Community Plan’s Arizona manual requires network providers to submit within 90 days of the date of service (or your contract’s terms); non-participating providers get 180 days. Corrected claims are due within one year, secondary claims within 180 days of the date of service.
The manual says to allow up to 30 days for payment of an initial claim and 45 days for an adjustment. AHCCCS requires 95% of clean claims within 30 days and 99% within 60, with interest on non-hospital clean claims paid after 45 days. No weekly cutoff or check-run day is published.
