AHCCCS — the Arizona Health Care Cost Containment System — covers Behavior Analysis Services under Medical Policy Manual chapter AMPM 320-S, and it is one of the friendliest coverage baselines in our directory: no autism diagnosis is strictly required, and the state policy itself imposes no prior-authorization rules. But Arizona is a two-front-door state, and routing the family correctly is the first intake job: most members get ABA through one of six AHCCCS Complete Care (ACC) managed care plans, while ALTCS-eligible members with developmental disabilities get it through DES/DDD, which runs two statewide DDD Health Plans — Mercy Care DD and UnitedHealthcare Community Plan DD. Ask "ACC plan or DDD?" before anything else, because the payer, portal, and authorization pathway all hang on the answer.
AMPM 320-S applies across every AHCCCS delivery system — ACC, ALTCS, DES/DDD, DCS/CMDP, the RBHA contracts, and fee-for-service tribal programs — but the operational path splits in two. Most children get ABA through their ACC plan: Arizona Complete Health-Complete Care Plan, Banner-University Family Care, Blue Cross Blue Shield of Arizona Health Choice, Mercy Care, Molina Healthcare, or UnitedHealthcare Community Plan (Care1st no longer exists — it merged into Arizona Complete Health, with northern-county members transferred in 2024). Children who are ALTCS-eligible through the Division of Developmental Disabilities — autism is a DDD qualifying-condition category — instead get physical and behavioral health including ABA through one of two statewide DDD Health Plans, Mercy Care DD or UHCCP DD. Over age 3, ALTCS approval is the gate to DDD-funded services. The intake question that routes everything: which card does the family hold, an ACC plan card or a DDD Health Plan card?[5][7][10]
AMPM 320-S states that Behavior Analysis Services are a covered benefit "for individuals with Autism Spectrum Disorder (ASD) and/or other diagnoses as justified by medical necessity" — Arizona is one of the states that does not strictly require an autism diagnosis for ABA. Services must be prescribed or recommended by a qualified Behavioral Health Professional based on assessment (the policy lists example instruments like the PDDBI, Brigance, and Vineland), and progress reports are required at minimum every 6 months with specified components. The state policy sets no prior-authorization rules of its own — PA is delegated to the contractors, and the two largest verified examples both skip PA on assessment: Mercy Care ("You don't need PA for adaptive behavior assessments: CPT codes 97151 and 97152") and UHC/Optum ("All ABA services require prior authorization except 97151 and 97152"). Treatment codes do require PA at those plans, on their own forms and cadences — see the per-plan guides. For the three plans with no published ABA policy (Banner, Health Choice, Molina), verify the current PA rules in the portal before quoting a start date.[5][19][20]
AHCCCS sets its own timeliness standard for behavioral health, and it is the one to design an ABA intake around. ACOM Policy 417 (current version effective October 1, 2026), which binds the ACC, ACC-RBHA, ALTCS E/PD and DDD contractors, requires the “Initial assessment – Within seven calendar days after the initial referral or request for behavioral health services”; then the “Initial appointment – Within timeframes indicated by clinical need” but, “For members under the age of 18 years old, no later than 21 days after the initial assessment” (23 calendar days for members 18 and older); and “Subsequent behavioral health services – Within the timeframes according to the needs of the person, but no longer than 45 calendar days from identification of need.” Urgent need is 24 hours. Children in Department of Child Safety custody and adopted children run on a separate, faster track under A.R.S. 8-512.01: screening and evaluation within seven calendar days, the initial appointment no later than 21 calendar days after it, and subsequent services no later than 21 calendar days after any screening and assessment.[4]
These are standards the health plan must meet through its network, not a claim rule, but they are the numbers a plan uses when it asks whether your agency can take a referral. For ABA the practical sequence is: see the child for the 97151 assessment within about a week of referral (the two largest plans, Mercy Care and UnitedHealthcare Community Plan, need no PA for 97151/97152), then have the treatment authorization decided and 97153 started inside the 21-day window. The plan's PA decision clock sits inside that window: 14 calendar days in most AHCCCS plan manuals, 7 calendar days under the federal rule that applies to managed care plans for rating periods starting on or after January 1, 2026 (see the authorization-timing field below).[4]
AHCCCS converted the ABA codes from by-report to fixed rates effective November 1, 2023, tiered by rendering credential via modifiers: HM = below bachelor's (BT/RBT level), HN = bachelor's (BCaBA), HO = master's (BCBA), HP = doctoral (BCBA-D). Per 15-minute unit: 97151 assessment pays $30.06 / $35.78 / $44.73 at the HN/HO/HP tiers; 97153 direct treatment pays $17.91 / $21.32 / $23.69 (HM/HN/HO-HP); 97155 protocol modification pays $25.05 / $29.82 / $37.28. Home delivery (POS 12) pays roughly a 10% premium on every code — 97153 at home runs $19.96–$26.43. Two traps: the 2023 rate notice did not set a rate for 97156 (family training) — check the AHCCCS physician fee schedule code lookup directly — and the 9715x codes are not on the Behavioral Health Outpatient fee schedule at all; they live on the physician fee schedule. Practices that look up "behavioral health rates" find nothing and assume ABA is unpriced — it isn't.[6][21][22]
Arizona ABA is mid-upheaval, and intake teams should track two live threads. First, AHCCCS is running a spending-driven ABA reform: proposed AMPM 320-S revisions previewed at April 15–16, 2026 webinars would make state licensure plus fingerprint clearance conditions of AHCCCS provider registration and change the PA process. The proposal went to AHCCCS's public comment portal (searchable as "AMPM Policy 320-S – Behavior Analysis Services") by August 2026, but it still hasn't landed: the live 320-S PDF, fetched directly from azahcccs.gov (accessed 10/1/2026), is unchanged from the original policy — same "EFFECTIVE DATE: 11/01/19, 10/01/20" and "APPROVAL DATES: 08/07/19, 05/07/20" header, same "ASD and/or other diagnoses as justified by medical necessity" coverage language, same silence on prior authorization. AHCCCS's own September 3, 2026 AMPM revision-transmittal memo confirms it: it lists additions and not-yet-effective changes across a dozen other policies (430, 1620-D, 320-X, 581, 320-O and more) but never mentions 320-S. So today's rules still govern — treat the rewrite as proposed, not pending. Second, news reports (azfamily, March 5, 2026) said Mercy Care, Arizona Complete Health and UnitedHealthcare were ending network contracts with Action Behavior Centers and Centria, that nearly 1,000 children would lose in-network ABA, and that 11 families had sued AHCCCS to halt the terminations. We have not found an AHCCCS notice or the court filing that confirms the details, so treat them as reported. For providers still in network, displaced families are actively seeking new placements: staff intake for that volume, and verify network status on every inbound rather than assuming last year's directory.[8][5][9][11]
AMPM 320-S never says "RBT." A Behavior Technician is "a paraprofessional credentialed by a nationally recognized Behavior Analyst certification board or as specified in A.A.C. R9-10-101(39)" — meaning either a nationally certified tech (the RBT pathway) or an unlicensed Behavioral Health Technician working at a licensed health care institution under Behavioral Health Professional oversight. There is no state RBT registry; the Arizona-licensed Behavior Analyst (A.R.S. § 32-2091, Board of Psychologist Examiners) is responsible for all clinical direction and supervision, for training technicians, and for their compliance with the policy — and because 320-S sets no numeric supervision percentage of its own, the BACB's floor is the binding number for RBT-credentialed staff: 5% of monthly service hours, including two face-to-face contacts. ADHS outpatient-treatment-center rules (R9-10-1011) add that personnel providing behavioral health services must be at least 18, and if you staff the RBT pathway, the BACB baseline travels with it: a criminal background check plus an abuse-registry check, both completed within 180 days before the certification application, and — from January 1, 2026 — the new 40-hour curriculum (delivered over 5–180 days by trained BCBAs/BCaBAs), an updated competency assessment, and a 2-year recertification cycle.[5][18][15][12][13][14][16][17]
Now the part Arizona owners most often get backwards: fingerprint clearance cards. AHCCCS enrollment screening itself barely touches your staff — per PEP-902, the fingerprint-based criminal background check (run exclusively through Arizona DPS; FBI checks and out-of-state cards are not accepted) applies to "high-risk" provider types like 77 Behavioral Health Outpatient Clinic and IC Integrated Clinic, and only to individual high-risk providers, 5%+ direct or indirect owners, and the Directors/Executive Directors/CEOs/Presidents on the Corporation Commission listing; employees below that line are expressly exempt. But front-line staff need DPS cards anyway — the trigger is just elsewhere. Under A.R.S. § 36-425.03, all personnel, volunteers included, of a children's behavioral health program (behavioral health services to patients under 18 at an ADHS-licensed facility) must hold a valid fingerprint clearance card or apply within 7 working days of starting, and must certify on notarized forms that they are not awaiting trial on or convicted of the offenses listed in A.R.S. § 41-1758.03. Licensed behavior analysts carry their own card requirement as a condition of licensure (A.R.S. § 32-2091.02, effective January 1, 2022) — and the proposed 2026 AMPM rewrite would push licensure-plus-fingerprint into AHCCCS registration itself.[5][18][15][12][13][14][16][17]
The DDD side of the dual path layers on the heaviest screening. Qualified Vendors must hold Level One fingerprint clearance cards (A.R.S. § 41-1758.07) for all employee types except immediate relatives, add staff to the roster within 30 days of hire, and the OLCR tracking system re-validates every card against DPS every 24 hours — an expired card surfaces the next day, not at revalidation. DDD also screens staff against the APS Registry automatically every 24 hours, requires DCS Central Registry (child abuse/neglect) checks under A.R.S. § 8-804 for anyone providing direct service to children — with a Direct Service Position Form (DDD-1727A) completed before service pending results — and mandates monthly LEIE and SAM exclusion searches for all employees, contractors, and subcontractor staff, with results retained 5 years. New direct-care workers get 90 days to complete CPR, First Aid, and Article 9 training and cannot work alone with members until they do. Two gaps to confirm directly: AMPM 320-S is silent on TB tests or health screening for ABA staff (any such duty flows from the R9-10 article your ADHS license class sits under), and the ACC plans publish no staff screening beyond the state baseline — Mercy Care defers clinical standards to AHCCCS policy — so confirm plan-specific credentialing paperwork at contracting.[5][18][15][12][13][14][16][17]
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.[14][27][28][29][5][30]
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.[14][27][28][29][5][30]
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 the clock is the same in fee-for-service and in an ACC plan. 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.”[31][32][33][2][34][35][36][37]
Payment. For fee-for-service claims AHCCCS “intends to process all clean claims in a timely manner, normally within 30 days” (FFS manual, Chapter 25) — a processing target, not a statutory deadline. For the health plans, ACOM 203 sets the standard “unless a subcontract specifies otherwise”: 95% of clean claims adjudicated within 30 days of receipt and 99% within 60, and interest at 10% a year from the 46th day on a non-hospital clean claim paid after 45 days. AHCCCS publishes no weekly submission cutoff or check-run day; each plan sets its own payment cycle.[31][32][33][2][34][35][36][37]
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); disputes for plan-enrolled members are filed with the member’s health plan. An unfavourable Notice of Decision can be taken to a state fair hearing within 30 days of receipt.[31][32][33][2][34][35][36][37]
Taxonomy. AHCCCS’s CMS-1500 instructions put the rendering provider’s NPI in the unshaded part of box 24J (required) and its 10-character taxonomy in the shaded part with qualifier ZZ in 24I, and the billing provider’s taxonomy in 33b — the taxonomy entries marked “required if applicable.”[31][32][33][2][34][35][36][37]
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.[31][32][33][2][34][35][36][37]
Not for ABA under the fee-for-service billing rules. AHCCCS’s CMS-1500 chapter marks field 17, "Name of Referring Provider or Other Source," as "Required if applicable," with qualifiers DN (referring), DK (ordering) and DQ (supervising). The services that require an ordering provider are listed: laboratory, drugs (J-codes), radiology, temporary K and Q codes, medical and surgical supplies, orthotics, respiratory, DME, prosthetics, enteral and parenteral therapy, vision (V-codes), diabetes self-management and chiropractic services. Behavior analysis codes are not on that list.[35]
When you do report a provider in field 17, the chapter makes 17b, the provider’s NPI, "Required." This chapter governs AHCCCS fee-for-service claims. Health plans (Mercy Care, UnitedHealthcare Community Plan, AzCH, BUFC, Health Choice, Molina and DDD) publish their own claim manuals, so check the member’s plan before assuming the same answer.[35]
The questions that decide whether a family can start with AHCCCS (Arizona Medicaid), and what they have to bring. Each maps onto something intake should ask on the first call.
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.[5]
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.[5]
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.[5]
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.[5]
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."[5][20][19]
All eight ABA CPT codes can be billed by telehealth, with the GT modifier and the member’s own location as the place of service. AHCCCS’s Telehealth Code Set (sheet effective 06/01/2026) lists 97151, 97152, 97153, 97154, 97155, 97156, 97157 and 97158 for interactive audio-video (GT); none of them carries the FQ audio-only modifier, and 0362T and 0373T are not on the code set. So the initial behavior identification assessment and reassessments (97151, 97152) and analyst direction of the technician (97155) can all be delivered remotely. AMPM 320-I sets the claim rule: “the POS on the service claim is the originating site,” meaning where the member is (for example 12 home, 03 school, 11 office), and the code set’s guidelines state “AHCCCS will not be utilizing POS 02 and POS 10 for telehealth,” except where 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).” AHCCCS publishes no in-person share for supervision; the Behavior Analyst remains responsible for “all aspects of clinical direction, supervision, and provider-level case management.” Health plans may add their own authorization rules, so check the member’s Contractor.[23][24][5]
Fee-for-service (AIHP/tribal and other FFS members): since January 1, 2026, 42 CFR 440.230(e) requires state FFS decisions "in no case later than 7 calendar days after receiving the request" for standard and 72 hours for expedited (standard extendable up to 14 calendar days). Health plans: 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. AHCCCS’s contractor policy ACOM 414 (rev. March 2025) still reads "no later than 14 calendar days from receipt of the request for the service, regardless of whether the 14th day falls on a weekend", 72 hours expedited, each extendable up to 14 more calendar days. Expect 7 and confirm with the plan; individual plan manuals still vary (see each plan). No ABA-specific decision clock or reauthorization lead time is published; AMPM 320-S requires progress reports at least every six months, which is what the reauth is built from. The decision clock sits inside a service-start clock: ACOM 417 (current version eff. 10/1/2026) requires the behavioral health "Initial assessment – Within seven calendar days after the initial referral" and, for members under 18, the initial appointment "no later than 21 days after the initial assessment" (23 calendar days for adults).[39][40][41][42][5][4]
"AHCCCS is the payer of last resort unless specifically prohibited by state or federal law." AHCCCS policy (ACOM 434) makes the plan payer of last resort — bill the commercial plan first — but separates its authorization from the other insurer’s: "A denial of the service request by a third-party is not to be used as a basis for the Contractor's determination of medical necessity" (the plan reviews on its own criteria), and "When a third-party has approved a service request as medically necessary, the Contractor shall not apply a secondary Prior Authorization (PA)." Plans pay first and recover later for preventive pediatric/EPSDT services (the ACOM 434 list for children under 21 includes "Therapies, and Behavioral Health Exams") and absent-parent support cases. In fee-for-service, PA is not required when "The member has Medicare, third party liability (TPL), or commercial insurance coverage and the services are covered by Medicare, TPL, or commercial insurance"; if the other insurer denies, "the provider must follow the payer's appeal process and exhaust all remedies before AHCCCS can consider the covered service", attaching the final appeal decision and the EOB/RA. AHCCCS pays up to the difference between its allowed amount and the primary payment and does not separately reimburse copays, deductibles or coinsurance. Under federal rules TRICARE pays before Medicaid, and CHAMPVA pays first when the child is also Medicaid-eligible.[43][44][45][46][47]
Coverage decides whether AHCCCS (Arizona Medicaid) 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.
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.[5]
No per-day unit ceiling in AHCCCS policy; the ceiling is the authorization, and on fee-for-service claims the federal Medicaid MUE. AMPM 320-S sets none — services are prescribed "in specific dosages, frequency, intensity, and duration" by the recommending BHP — and the Behavioral Health Services Matrix it points to (October 2026 sheet) lists provider types, places of service and modifiers per code, with no unit column. The FFS billing manual says only that "Some procedures have a limit on the number of units that can be provided to a member during a given time span," and that all units for one procedure on one date go on one claim line. For fee-for-service claims (AIHP, tribal programs) CMS requires the Medicaid NCCI edits, applied "separately to each line of a claim"; the public practitioner MUE table effective 10/1/2026 allows 97153 32 units, 97151 32, 97152 16, 97154 18, 97155 24, 97156 16, 97157 16, 97158 16, 0362T 16 and 0373T 32. For ACC and DDD plans CMS calls those edits "desirable but optional," so each plan’s own claim edits and the authorized units govern.[5][25][32][35][3][1]
Home, school, clinic and community are all codeable. AMPM 320-S requires the treatment plan to “specify the setting(s) in which services will be delivered” and points to the Behavioral Health Services Billing Matrix “regarding required coding information, including covered settings.” The Matrix (as of 9/1/26) lists the same places of service for 97151 through 97158 for Board Certified Behavior Analyst (BC) and ABA organization (AB) provider types: 03 school, 05–08 Indian Health Service and tribal sites, 09 prison, 11 office, 12 home, 14 group home, 16 temporary lodging, 19 and 22 outpatient hospital, 49 independent clinic, 50 FQHC, 51–54 psychiatric facilities, community mental health centers and ICF/IID, 71–72 public health and rural health clinic, and 99 other. Setting changes the fee-for-service rate: the November 2023 fixed-rate notice pays home delivery (POS 12) more than all other places of service on every ABA code (97153 at HM level $19.96 home against $17.91 elsewhere). AMPM 320-S sets no school-specific restriction; ask the member’s Contractor how it handles school-based delivery alongside an IEP.[5][25][6]
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)."[5][6][19]
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."[5]
Blocked on: The AHCCCS Behavioral Health Services Billing Matrix and Medical Coding Resources (azahcccs.gov blocked automated retrieval at this review), and the Contractor's own reimbursement policy.
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.[5]
Blocked on: The Contractor's provider manual and the AHCCCS AMPM documentation chapters; ADHS licensure rules (A.A.C. R9-10) for the health care institution's own record standards.
AHCCCS’s behavioral health appointment standard (ACOM 417, current version eff. 10/1/2026) sets the clock for every ACC, ACC-RBHA, ALTCS E/PD and DDD plan: the initial assessment within seven calendar days of the referral or request, and the initial appointment “no later than 21 days after the initial assessment” for members under 18 (23 calendar days for adults), with later services no more than 45 calendar days from identification of need. For children in DCS custody and adopted children, the initial appointment is due no later than 21 calendar days after screening and evaluation. The standard binds the plan's network, so plans refer to agencies that can meet it. The treatment PA decision (14 calendar days in most plan manuals, 7 under the 2026 federal rule) has to fit inside the 21 days.
Yes — under AMPM 320-S, for members with autism spectrum disorder and/or other diagnoses as justified by medical necessity. Coverage runs through the member's ACC plan, or through a DDD Health Plan (Mercy Care DD or UHCCP DD) for ALTCS-DD members.
No — AMPM 320-S explicitly covers "other diagnoses as justified by medical necessity," and Optum's Arizona orientation states verbatim that an ASD diagnosis is not required for AHCCCS members. A qualified Behavioral Health Professional must still recommend the service based on assessment.
Fixed, credential-tiered rates since 11/1/2023: 97153 pays $17.91 (HM) / $21.32 (HN) / $23.69 (HO/HP) per 15-minute unit, with home delivery about 10% higher. The codes live on the physician fee schedule, not the behavioral-health outpatient one, and 97156 wasn't in the 2023 rate notice — look it up directly.
Six ACC plans — Arizona Complete Health, Banner-University Family Care, Blue Cross Blue Shield of Arizona Health Choice, Mercy Care, Molina, and UnitedHealthcare Community Plan — plus the two statewide DDD Health Plans (Mercy Care DD and UHCCP DD) for ALTCS-DD members. Prior-auth mechanics are plan-specific.
Yes. AHCCCS’s Telehealth Code Set lists 97151 through 97158 for interactive audio-video with the GT modifier, so the assessment (97151, 97152) and analyst direction of the technician (97155) can be remote. The place of service is where the member is (for example 12 home); AHCCCS does not use POS 02 or 10. Audio-only (FQ) is not listed for these codes.
The Behavioral Health Services Matrix lists POS 03 (school) as a valid place of service for 97151 through 97158. AMPM 320-S requires the treatment plan to name the settings but sets no school-specific restriction; ask the member’s health plan how it handles school-based delivery alongside an IEP.
Not necessarily. AHCCCS says its fixed ABA rates apply only to fee-for-service programs (AIHP, Tribal ALTCS, DDD Tribal Health Program), and “MCOs and providers may negotiate any contracted rate that is agreed to by both parties.” For a plan member, the rate is in your plan contract.
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.
For fee-for-service members, AHCCCS’s FFS manual (Chapter 8) says no PA is required for “Services provided prior to the posting of the member’s retroactive eligibility.” Health plan members follow their plan’s retrospective-review rules, which differ by plan (see each plan guide).
Six months from the date of service (or from the date eligibility is posted, if later) for the first submission, and twelve months to get the claim to clean-claim status. A.R.S. § 36-2904(G) applies the same limits to AHCCCS fee-for-service and to its contracted health plans.
Not as ABA. AMPM 540 limits EVV to personal care and home health services — AHCCCS names attendant care, personal care, homemaker, habilitation, respite and in-home skilled nursing — and a visit is covered only when provider type, service code and place of service all match AHCCCS’s list.
In writing within twelve months of the date of service (or of eligibility posting), or sixty days after the denial of a timely claim, whichever is later. Fee-for-service disputes go to AHCCCS’s Office of General Counsel; plan members’ disputes go to their health plan. A state fair hearing can be requested within 30 days of an unfavourable decision.
Not under the fee-for-service CMS-1500 rules. Field 17 is "Required if applicable," and AHCCCS requires an ordering provider only for lab, drugs, radiology, supplies, DME and similar items, not behavior analysis. If you fill field 17, include the NPI in 17b. Health plans may set their own rules.
