Understanding ABA Therapy Insurance Coverage in Arizona (2026 Guide)

March 23, 2026

Yes, insurance covers
ABA therapy
in Arizona.

In fact, 79% of families at Treetop ABA pay $0 out of pocket. Arizona actually
has one of the stronger autism insurance mandates in the country, thanks to
Steven’s Law.

This guide breaks down exactly what Arizona families need to know about ABA
therapy insurance coverage in 2026. We’ll cover Steven’s Law, AHCCCS (Arizona
Medicaid), self-funded plans, and the step-by-step process to verify your
benefits and get started.

Steven’s Law: Arizona’s Autism Insurance Mandate (A.R.S. § 20-826.04)

Arizona passed Steven’s Law in 2008, making it one of the earlier states to
mandate autism insurance coverage. The law requires state-regulated health
insurance plans to cover the diagnosis and treatment of autism spectrum
disorder, including ABA therapy.

Here’s what the law guarantees:

  • Children under age 9: Up to $50,000 per year in
    autism-related services.
  • Children ages 9 through 16: Up to $25,000 per year in
    autism-related services.
  • No lifetime cap on the total amount of coverage.

These are minimums. Your plan may cover more. The dollar amounts apply to
autism-specific treatments like ABA therapy, speech therapy, and occupational
therapy combined.

A few important details about Steven’s Law:

  • It applies to state-regulated insurance plans, including
    most individual and small-group plans purchased through the marketplace or
    through employers with fewer than 50 employees.
  • Coverage must include evaluation, assessment, and treatment of autism.
  • The law does not set a minimum number of therapy hours. Your approved hours
    depend on your child’s treatment plan and what the insurance company
    authorizes.
  • Coverage resets each plan year, so benefits renew annually.

For many families, these caps cover the full cost of a recommended ABA
program. A typical program running 15 to 25 hours per week often falls within
the $50,000 annual limit for younger children.

AHCCCS (Arizona Medicaid): No Dollar Cap

If your child is enrolled in AHCCCS, Arizona’s Medicaid program, you may have
the most comprehensive ABA coverage available in the state.
AHCCCS has no annual dollar cap on ABA therapy.

Under the federal Early and Periodic Screening, Diagnostic and Treatment
(EPSDT) benefit, Medicaid must cover any medically necessary treatment for
children under 21. ABA therapy qualifies when your child has an autism
diagnosis and a treatment plan showing medical necessity.

What AHCCCS coverage looks like in practice:

  • No dollar limit. Coverage is based on medical necessity,
    not an annual cap.
  • Up to 40 hours per week of ABA therapy can be authorized
    when clinically appropriate.
  • Covers all service settings:
    center-based,
    in-home, and school-based
    therapy.
  • No copays for most AHCCCS members under 19.

AHCCCS delivers services through managed care organizations like Mercy Care,
UnitedHealthcare Community Plan, Banner-University Family Care, and Arizona
Complete Health. Your specific managed care plan handles authorizations and
provider networks.

Treetop accepts AHCCCS and most AHCCCS managed care
plans. Our team can help you figure out which plan you have and what steps to
take.

Self-Funded Employer Plans (ERISA)

If you get insurance through a large employer, your plan may be “self-funded.”
This means your employer pays claims directly rather than purchasing a
traditional insurance policy from a carrier.

Self-funded plans are regulated by federal law (ERISA), not state law. That
means Steven’s Law doesn’t technically apply to them. The $50,000 and $25,000
annual caps don’t bind self-funded plans.

That said, most large self-funded plans still cover ABA therapy. Many major
employers voluntarily include autism benefits. The Federal Mental Health
Parity and Addiction Equity Act also requires self-funded plans to cover
behavioral health services at the same level as medical/surgical services.

How to find out if your plan is self-funded:

  • Check your Summary Plan Description (SPD), usually available from HR.
  • Call your HR department and ask directly.
  • Look at your insurance card. If it says “ASO” (Administrative Services
    Only), it’s likely self-funded.

Even if your plan is self-funded, don’t assume ABA isn’t covered. Check your
specific benefits or let our team verify for you.

How to Verify Your ABA Therapy Coverage in Arizona

Before starting ABA therapy, take these steps to understand exactly what your
plan covers:

1. Call the number on the back of your insurance card. Ask
specifically about “Applied Behavior Analysis for autism spectrum disorder.”
General customer service may not know the details, so request the behavioral
health department.

2. Ask these specific questions:

  • Is ABA therapy covered under my plan?
  • What is my annual benefit limit for ABA services?
  • Do I need a referral or prior authorization?
  • What is my copay or coinsurance for ABA therapy?
  • Is there an age limit on coverage?
  • Does my plan fall under Steven’s Law (A.R.S. § 20-826.04)?

3. Get the answers in writing. Ask for a benefits summary or
confirmation email. This protects you if there’s ever a dispute.

4. Ask about in-network providers. Using an
in-network provider means lower out-of-pocket
costs. Treetop is in-network with most major Arizona insurance plans.

If this process feels overwhelming, you’re not alone. Treetop’s insurance team
verifies benefits for Arizona families every day, at no cost to you.

The Authorization Process: What to Expect

Most insurance plans require “prior authorization” before ABA therapy can
start. This is standard. Here’s what the process looks like step by step:

Step 1: Diagnostic evaluation. Your child needs a formal
autism spectrum disorder diagnosis from a qualified professional
(pediatrician, psychologist, or developmental specialist).

Step 2: BCBA assessment. A Board Certified Behavior Analyst
conducts a comprehensive assessment and creates a treatment plan with specific
goals and recommended hours per week.

Step 3: Submit for authorization. The treatment plan is
submitted to your insurance company for review. This includes clinical
justification for the recommended hours.

Step 4: Insurance review. Your insurance company reviews the
plan and approves a specific number of hours. This typically takes 2 to 4
weeks.

Step 5: Therapy begins. Once authorized, your child starts
ABA therapy. Reauthorization is usually required every 6 months, based on
progress reports.

At Treetop, our team handles the entire authorization process for you. Most
families
start therapy within 4 weeks
of their first call.
