# Arizona DES/DDD ABA coverage (the ALTCS-DD path).

_Payer Guide · Arizona DES/DDD · Last updated September 2026 · 6 primary sources_

> The second funnel: ALTCS-DD members get ABA via Mercy Care DD or UHCCP DD, statewide.

The Division of Developmental Disabilities (DES/DDD) is Arizona's second ABA funnel: ALTCS-eligible members with developmental disabilities get their physical and behavioral health — including ABA — not through an ACC plan but through one of two statewide DDD Health Plans, Mercy Care DD or UnitedHealthcare Community Plan DD (both effective October 2019). Clinically nothing changes — AMPM 320-S governs DES/DDD by its own terms — but structurally this is a separate eligibility gate and plan-choice flow, and routing a DDD family down the ACC path (or vice versa) burns weeks. Intake teams that ask the DDD question first route correctly.

This plan administers the **AHCCCS (Arizona Medicaid)** ABA benefit: the state rules are the floor, and this page covers what the plan layers on top. Read it together with the [AHCCCS (Arizona Medicaid) guide](https://carelu.com/payers/arizona-ahcccs).

## Prior authorization and diagnosis at a glance

- **Prior auth for the assessment**: Follows the member's DDD Health Plan — Mercy Care DD and UHCCP DD both skip PA on 97151/97152 [1][6][5]
- **Prior auth for treatment**: Through the member's DDD Health Plan (Mercy Care DD or UHCCP DD), on the same ABA PA machinery as their ACC lines [1][6][5]
- **Autism diagnosis required?**: No — AMPM 320-S applies; autism is a DDD qualifying-condition category, but ABA rides on medical necessity [2][1]

## At a glance

- **What it is:** The ALTCS-DD path — DDD subcontracts health care to two statewide DDD Health Plans
- **The plans:** Mercy Care DD and UHCCP DD ("DD by UHCCP") — member chooses; both statewide
- **Clinical rules:** AMPM 320-S — identical to the ACC path
- **Eligibility gate:** Over age 3, ALTCS approval is the gate to DDD-funded services; autism is a qualifying-condition category
- **Assessment PA:** None at either DDD plan — same 97151/97152 rule as their ACC lines
- **Bundled services:** DDD members also get habilitation and respite (HCBS) alongside ABA

## The dual path, from the DDD side

Children under 21 can get ABA either through their ACC plan under EPSDT or — if ALTCS/DDD-eligible — through a DDD Health Plan. Autism is a DDD qualifying-condition category, and over age 3 ALTCS approval is the gate to DDD-funded services (habilitation, respite, ABA). Once eligible, the family chooses between Mercy Care DD and UHCCP DD, and unlike the ACC side, both DDD Health Plans are statewide — county doesn't restrict DDD members the way ACC geographic service areas do. Authorization then runs through the chosen plan's ABA machinery, identical to its ACC line: no PA on 97151/97152 at either plan, treatment PA on their respective forms (Mercy Care's ABA PA form with 6-month auths; Optum's Provider Express Treatment Form for UHCCP DD). DDD ALTCS also maintains its own service-approval matrix on the LTSS side. [1][2][3]

## Why the DDD conversation is different at intake

A DDD family isn't just an ABA inquiry — DDD members also receive habilitation and respite through home- and community-based services alongside ABA, a bundled-service conversation ACC-only families never have. Intake that recognizes a DDD card (UHCCP DD cards read "DDD Health Plan by UHCCP," Group AZDDD; Mercy Care DD is branded accordingly) can coordinate the ABA request with the family's DDD support coordinator instead of working blind. For families who look DDD-eligible but aren't enrolled, the ALTCS application is the long pole — flag it early, and run the ACC path in parallel where EPSDT coverage already exists. [1][5]

## Intake gates

The questions that decide whether a family can start with DES/DDD (Arizona Division of Developmental Disabilities), and what they have to bring.

- **Age limit**: Identical to the ACC path — AMPM 320-S applies to DES/DDD by its own terms, and authorization then runs through the member's chosen DDD Health Plan (Mercy Care DD or UHCCP DD) on that plan's ABA machinery: 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. [2][1]
- **Diagnosis recency**: Identical to the ACC path — AMPM 320-S applies to DES/DDD by its own terms, and authorization then runs through the member's chosen DDD Health Plan (Mercy Care DD or UHCCP DD) on that plan's ABA machinery: 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. [2][1]
- **Who may diagnose**: Identical to the ACC path — AMPM 320-S applies to DES/DDD by its own terms, and authorization then runs through the member's chosen DDD Health Plan (Mercy Care DD or UHCCP DD) on that plan's ABA machinery: 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. [2][1]
- **Diagnostic tools required**: Identical to the ACC path — AMPM 320-S applies to DES/DDD by its own terms, and authorization then runs through the member's chosen DDD Health Plan (Mercy Care DD or UHCCP DD) on that plan's ABA machinery: 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. [2][1]
- **Referral required?**: Identical to the ACC path — AMPM 320-S applies to DES/DDD by its own terms, and authorization then runs through the member's chosen DDD Health Plan (Mercy Care DD or UHCCP DD) on that plan's ABA machinery: 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." [2][6][5][1]
- **Prior-auth decision time**: DDD’s own policy and the policy for its health plans (AdSS — Mercy Care DD and UHC Community Plan DD, which authorize ABA) both still read "no later than 14 Calendar Days from receipt of the request for the service regardless of whether the 14th day falls on a weekend … or Legal Holiday", 72 hours expedited, each extendable up to 14 more days. 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 the DDD health plan which clock it runs. 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. [7][8][9][10][2]
- **Other insurance (who pays first)**: DDD pays last and must "independently evaluate the Member's service request using its own criteria" when a third party denies; "when a Third Party has approved a service request as medically necessary" it must "Not apply a secondary prior authorization" and coordinate payment. It pays first and recovers later for preventive pediatric/EPSDT services, a list that includes "Therapies, and behavioral health exams." DDD Qualified Vendors bill the other insurer first (including high-deductible plans), obtain the EOB or denial, and bill the difference up to the contracted rate. Under federal rules TRICARE pays before Medicaid, and CHAMPVA pays first when the child is also Medicaid-eligible. [11][12][13][14]

## Delivery and billing rules

Coverage decides whether DES/DDD (Arizona Division of Developmental Disabilities) pays. These decide whether the claim survives: staffing and supervision, concurrent billing, per-day ceilings, who signs the note, where the service is payable, and whose NPI the claim goes out under.

- **Supervision**: Identical to the ACC path — AMPM 320-S applies to DES/DDD by its own terms, and authorization then runs through the member's chosen DDD Health Plan (Mercy Care DD or UHCCP DD) on that plan's ABA machinery: 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. [2][1]
- **Bill as provider**: Identical to the ACC path — AMPM 320-S applies to DES/DDD by its own terms, and authorization then runs through the member's chosen DDD Health Plan (Mercy Care DD or UHCCP DD) on that plan's ABA machinery: 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)." [2][4][5][1]
- **Concurrent billing (97153 + 97155):** Not published / unverified. Verify via: The member's DDD Health Plan — Mercy Care DD or UnitedHealthcare Community Plan DD — plus the DDD support coordinator on the service-plan side. [2][1]
- **Session-note signature** _(ask the plan)_: Identical to the ACC path — AMPM 320-S applies to DES/DDD by its own terms, and authorization then runs through the member's chosen DDD Health Plan (Mercy Care DD or UHCCP DD) on that plan's ABA machinery: 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. [2][1]
  - Ask the plan: The member's DDD Health Plan — Mercy Care DD or UnitedHealthcare Community Plan DD — plus the DDD support coordinator on the service-plan side.

## What intake should collect for DES/DDD (Arizona Division of Developmental Disabilities)

- **DDD enrollment + ALTCS status:** Enrolled DDD member, ALTCS application pending, or ACC-only — three different routes with different timelines.
- **Which DDD Health Plan:** Mercy Care DD or UHCCP DD — the choice sets the PA form, portal, and auth cadence.
- **Support coordinator contact:** DDD members have one — coordinate the ABA request with the existing service plan.
- **Other DDD services in place:** Habilitation and respite hours shape the realistic ABA schedule.

## Verification of benefits (VOB) data

How DES/DDD (Arizona Division of Developmental Disabilities) ABA benefits route and read on an eligibility check. Data last updated 2026-07-23.

### EDI routing

- **Supports 270/271 eligibility:** Yes
- **Real-time eligibility:** Yes
- **Behavioral health administrator:** The member's DDD Health Plan (Mercy Care DD → 86052, or UHCCP DD → 03432)
- **BH administrator payer ID:** 86052 / 03432
- **ABA rides on:** medical benefit
- **Two-hop verification required:** No
- **Where the 271 carries MCO enrollment:** DDD enrollment surfaces in the AHCCCS 271 via EB05 descriptions "DDD Subcontractor Plan" / "DES/DDD Targeted Support Coordination" (e.g. EB*3*IND*CQ**DES/DDD TARGETED SUPPORT COORDINATION with DTP*292), 2120C NM103 "DDDS Code and Description", and contract-type codes @ (DES/DD/RI) and S (MHS/CAP/DD). The member's actual DDD Health Plan (Mercy Care DD or UHCCP/APIPA DD) appears as the NM1*Y2 managed-care enrollment — so eligibility resolves in ONE AHCCCS 270/271 hop, and ABA then rides that plan's payer ID.
- **Eligibility span granularity:** Daily (same AHCCCS 271 mechanics as arizona-ahcccs).

Code notes:

- **97151, 97152, 97153, 97154, 97155, 97156, 97157, 97158, 0362T, 0373T:** ALTCS-DD path — ABA rides Mercy Care DD or UHCCP DD, same PA machinery as those plans' ACC lines. AMPM 320-S covers ASD "and/or other diagnoses as justified by medical necessity" — no strict autism-dx requirement. Per-code daily unit caps are not published (AzCH uses hour bands, not caps).

### Medicaid rates

Source: Not separately published by the member's DDD Health Plan (Mercy Care DD / UHCCP DD). AHCCCS ACC/DDD plans are capitated, but ABA tracks the AHCCCS physician fee schedule (see arizona-ahcccs rates) as the public benchmark — the member's DDD Health Plan (Mercy Care DD / UHCCP DD)'s actual contracted rate is not published (and is NOT a statutory floor, unlike New Mexico). Effective 2023-11-01 (AHCCCS benchmark).

| Code | Rate | Unit | Modifier tiers |
| --- | --- | --- | --- |
| 97151 | Benchmark: $30.06 (HN) / $35.78 (HO) / $44.73 (HP) office — see arizona-ahcccs | 15min | — |
| 97152 | Benchmark: $21.49 (HM) / $25.58 (HN) / $28.43 (HO/HP) office — see arizona-ahcccs | 15min | — |
| 97153 | Benchmark: $17.91 (HM) / $21.32 (HN) / $23.69 (HO/HP) office — see arizona-ahcccs | 15min | — |
| 97154 | Benchmark: $4.48 (HM) / $5.33 (HN) / $5.92 (HO/HP) office — see arizona-ahcccs | 15min | — |
| 97155 | Benchmark: $25.05 (HN) / $29.82 (HO) / $37.28 (HP) office — see arizona-ahcccs | 15min | — |
| 97158 | Benchmark: $6.26 (HN) / $7.46 (HO) / $9.32 (HP) office — see arizona-ahcccs | 15min | — |

### Contacts

- **Phone menu path:** Ask which DDD Health Plan the member is enrolled in — Mercy Care DD or UHCCP DD — first; routing, the PA form, and the phone/fax used all depend on that answer (see mercy-care-arizona / unitedhealthcare-community-plan-arizona contacts).

Questions to ask on a verification call:

- Which DDD Health Plan is the member enrolled in — Mercy Care DD or UHCCP DD?
- Is there a daily or weekly unit cap on 97153–97155 treatment codes, and over what period?
- Is telehealth allowed for ABA codes, and does it need a specific POS or modifier?
- What POS codes (home, clinic, school, community) do you actually accept on ABA claims?

## Common questions

### How do DDD members get ABA in Arizona?

Through their chosen DDD Health Plan — Mercy Care DD or UHCCP DD, both statewide — on the same AMPM 320-S clinical rules and the same plan-level ABA PA machinery as those plans' ACC lines.

### Can a child get ABA through an ACC plan instead of DDD?

Yes — children under 21 can get ABA via their ACC plan under EPSDT even without DDD. If the child is ALTCS/DDD-eligible, the DDD path adds bundled services (habilitation, respite); over age 3, ALTCS approval is the gate.

### Does county matter for DDD members?

No — both DDD Health Plans are statewide, unlike ACC plans, which are restricted to geographic service areas.
