Molina Healthcare of Arizona is the newest and smallest ACC plan — it entered with the 2022 ACC awards and covers three counties (Maricopa, Gila, Pinal), making it Phoenix-metro-centric. Like Banner and Health Choice, it publishes no distinct ABA clinical policy: the honest picture is the AMPM 320-S state baseline, with Molina's Prior Auth and Pre-Service Review Guide and its Healthcare Services line as the operational front door. Every ABA specific for this plan should be verified directly before quoting it to a family.
Nothing we could verify shows Molina layering clinical criteria beyond AMPM 320-S — so the coverage conversation follows the state guide: no strict autism-diagnosis requirement, BHP-recommended services based on assessment, 6-month progress reports. The mechanics run through Molina's Prior Auth and Pre-Service Review Guide, with PA initiated via Healthcare Services at (844) 782-2678 or fax (833) 832-1015, and Availity Essentials as the encouraged submission portal. The guide's current ABA rows — including whether 97151/97152 need PA — are the thing to check on first contact, because none of it is published as a standing ABA rule.[7][8]
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.[13][14][15][16][8][17][18]
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.[13][14][15][16][8][17][18]
Federal rules make the state Medicaid enrollment rule binding on the plan: the state “must screen and enroll, and periodically revalidate, all network providers” of Medicaid managed care plans (42 CFR 438.602(b)(1)). So a BCBA in Molina’s network has to be enrolled with AHCCCS as well.[13][14][15][16][8][17][18]
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 Molina Healthcare of Arizona 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.”[19][20][6][21][22][23]
Payment. 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. Other AHCCCS plans write shorter filing limits into their own manuals (Banner and AzCH use 120 days, UnitedHealthcare Community Plan 90), and Molina’s Arizona manual could not be retrieved at this review, so check your Molina contract for its filing limit and payment terms.[19][20][6][21][22][23]
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 Molina Healthcare of Arizona members the dispute is filed with Molina Healthcare of Arizona. An unfavourable Notice of Decision can be taken to a state fair hearing within 30 days of receipt.[19][20][6][21][22][23]
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.[19][20][6][21][22][23]
The questions that decide whether a family can start with Molina Healthcare of Arizona, and what they have to bring. Each maps onto something intake should ask on the first call.
Follows the AHCCCS rule — Molina publishes no distinct ABA clinical policy, only its Prior Auth and Pre-Service Review Guide: AMPM 320-S sets no age bound of its own. Behavior Analysis Services are covered "for individuals with Autism Spectrum Disorder (ASD) and/or other diagnoses as justified by medical necessity," and the policy applies across ACC, ALTCS E/PD, DCS/CMDP, DES/DDD, the RBHA contracts and fee-for-service programs without an age criterion. In practice children reach the benefit through EPSDT, and nothing in the policy text excludes adults — screen on medical necessity, not birthday.[8][7]
Follows the AHCCCS rule — Molina publishes no distinct ABA clinical policy, only its Prior Auth and Pre-Service Review Guide: None at the state level. AMPM 320-S imposes no recency clock on the diagnostic evaluation — and no autism diagnosis at all is strictly required. What must be current is the assessment: services are "prescribed or recommended in specific dosages, frequency, intensity, and duration by a qualified BHP as the result of an assessment of the member." Plan-level overlays can be stricter, so check the per-plan guide before telling a family an old evaluation still counts.[8][7]
Follows the AHCCCS rule — Molina publishes no distinct ABA clinical policy, only its Prior Auth and Pre-Service Review Guide: AMPM 320-S gates on who recommends ABA, not on who diagnoses: services must be "prescribed or recommended... by a qualified BHP." A Behavioral Health Professional is defined as an individual licensed under A.R.S. Title 32, Chapter 33 whose scope allows independent behavioral health practice (or practice under direct supervision, except a licensed substance abuse technician); a psychiatrist (A.R.S. § 36-501); a psychologist (A.R.S. § 32-2061); a physician; a Behavior Analyst (A.R.S. § 32-2091); a registered nurse practitioner licensed as an adult psychiatric and mental health nurse; or a registered nurse with psychiatric-mental health certification or one year of behavioral health experience.[8][7]
Follows the AHCCCS rule — Molina publishes no distinct ABA clinical policy, only its Prior Auth and Pre-Service Review Guide: No single instrument is mandated. "Behavior Analysis Services shall be based upon assessment(s) that include Standardized and/or Non-standardized instruments through both direct and indirect methods." Standardized examples named in the policy: the Pervasive Developmental Disabilities Behavior Inventory, the Brigance Inventory of Early Development and the Vineland Adaptive Behavior Scales. Non-standardized examples: curriculum-referenced assessments and stimulus preference assessment procedures.[8][7]
Follows the AHCCCS rule — Molina publishes no distinct ABA clinical policy, only its Prior Auth and Pre-Service Review Guide: A prescription or recommendation from a qualified Behavioral Health Professional, based on an assessment of the member, is the referral — AMPM 320-S requires nothing else and sets no prior-authorization rules of its own, leaving PA to the Contractors. The two largest plans both skip PA on the assessment codes: Mercy Care states no PA is needed for 97151 and 97152, and Optum's Arizona orientation states "All ABA services require prior authorization except 97151 and 97152."[8][12][11][7]
Molina’s April 2026 manual already runs the 7-day clock: "For a standard authorization request, Molina makes the determination and provides notification within seven (7) calendar days," outpatient standard pre-service "No later than 7 Calendar Days from the date the request was received", and expedited no later than 72 hours; behavioral health outpatient extensions add up to 14 calendar days from the extension notice. ABA is on Molina’s PA list; no reauth lead time is published.[25][7]
"Medicaid is always the payer of last resort": bill the primary payer and submit its EOB to Molina for secondary processing, reimbursed under the state COB methodology. "Molina will pay claims for prenatal care and preventive pediatric care (EPSDT) and then seek reimbursement from third parties." The manual does not say whether Molina’s own PA is needed when it is secondary; AHCCCS policy (ACOM 434) bars a secondary PA only when the other insurer approved the service as medically necessary. Under federal rules TRICARE pays before Medicaid, and CHAMPVA pays first when the child is also Medicaid-eligible.[25][26][27][28]
Unless Molina publishes something different (its Arizona provider manual could not be retrieved), 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.[5][4][8]

Coverage decides whether Molina Healthcare 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.
Follows the AHCCCS rule — Molina publishes no distinct ABA clinical policy, only its Prior Auth and Pre-Service Review Guide: A duty with no number attached. "Behavior Analysis Services shall be directed and overseen by Behavior Analysts and supported, where applicable, by Behavior Analysis Trainees and/or Behavior Technicians." The Behavior Analyst "is responsible for all aspects of clinical direction, supervision, and provider-level case management," for training Trainees and Technicians, for ensuring that "the extent, kind, and quality" of what they deliver matches their training and experience, and for their compliance with the policy and A.R.S. § 32-2091. A Behavior Analysis Trainee needs "direct and ongoing supervision consistent with the standards set by a nationally recognized Behavior Analyst certification board." AMPM 320-S publishes no supervision percentage and no caseload cap, so for RBT-credentialed staff the BACB floor is the operative number.[8][7]
Follows the AHCCCS rule — Molina publishes no distinct ABA clinical policy, only its Prior Auth and Pre-Service Review Guide: The claim line has to say who actually delivered the service. AHCCCS pays credential-tiered rates through modifiers — HM below bachelor's (technician level), HN bachelor's, HO master's, HP doctoral — and AMPM 320-S points to the Behavioral Health Services Billing Matrix for "modifiers for Behavior Analysis Trainee billing." Whose NPI goes in the rendering field is set per Contractor: UnitedHealthcare Community Plan, for instance, requires the rendering provider's 10-digit NPI in box 24J, "must be an active AHCCCS registered provider (The rendering provider is the BCBA/Licensed Clinician)."[8][10][11][7]
Follows the AHCCCS rule — Molina publishes no distinct ABA clinical policy, only its Prior Auth and Pre-Service Review Guide: AMPM 320-S does not address whether 97153 and 97155 may be billed for the same clock time. The policy routes every coding question elsewhere: "Refer to the Behavioral Health Services Billing Matrix and Medical Coding Resources on the AHCCCS website for more information regarding required coding information, including covered settings, modifiers for Behavior Analysis Trainee billing, or other billing/coding information."[8][7]

Follows the AHCCCS rule — Molina publishes no distinct ABA clinical policy, only its Prior Auth and Pre-Service Review Guide: AMPM 320-S sets no per-day ceiling (services are prescribed “in specific dosages, frequency, intensity, and duration” by the recommending BHP), and the AHCCCS Behavioral Health Services Matrix it points to lists provider types, places of service and modifiers with no unit column, so the authorization is the ceiling. CMS requires the Medicaid NCCI unit edits on fee-for-service claims but calls them “desirable but optional” for managed care plans; the public Medicaid MUE for 97153 is 32 units per claim line. Molina’s Arizona provider manual could not be retrieved (molinahealthcare.com serves a bot-wall page), so its own claim edits are unchecked.[8][1][2][3][7]
Blocked on: Molina Healthcare Services at (844) 782-2678 — ask whether Medicaid MUEs apply to ABA claim lines; the authorization states the units per code.
Follows the AHCCCS rule — Molina publishes no distinct ABA clinical policy, only its Prior Auth and Pre-Service Review Guide: AMPM 320-S sets a reporting cadence, not a signature rule. Progress reports are required "at minimum, every six months" and must include member identification; background information (family dynamics, school placement, cultural considerations, prenatal and/or developmental history, medical history, sensory, dietary and adaptive needs, sleep patterns, medications); assessment findings; outcomes (measurable objectives, progress toward goals, clinical recommendations, treatment dosage, family role and outcomes); and care coordination (transition statement and individualized discharge criteria). Who signs a session note, and within what window, is not stated.[8][7]

Follows the AHCCCS rule — Molina publishes no distinct ABA clinical policy, only its Prior Auth and Pre-Service Review Guide: AMPM 320-S requires the treatment plan to "specify the setting(s) in which services will be delivered" but publishes no payable-setting list, pointing instead to the Behavioral Health Services Billing Matrix "regarding required coding information, including covered settings." What is documented at the rate level is that setting changes the money: the November 2023 fixed-rate notice pays home delivery (POS 12) roughly 10% above the clinic rate on every ABA code.[8][10][7]

Yes — as an AHCCCS ACC plan on the AMPM 320-S baseline. Molina publishes no distinct ABA clinical policy; PA mechanics run through its Prior Auth and Pre-Service Review Guide and Availity Essentials.
Yes for treatment: Molina’s Prior Auth and Pre-Service Review Guide lists ABA for autism among the services that need prior authorization. Code-level rules, including whether the 97151/97152 assessment needs PA, are in Molina’s PA lookup tool; or call Healthcare Services at (844) 782-2678 before booking.
Three counties: Maricopa, Gila, and Pinal — the smallest ACC footprint, centered on Phoenix metro.
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.
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 limits for every AHCCCS contracted health plan, Molina Healthcare of Arizona included; the plan’s payment terms are in its contract and provider manual.
