Understanding Autism Insurance Mandates

Every state in the U.S. now requires some level of insurance coverage for autism treatment, including ABA therapy. These laws, known as autism insurance mandates, mean that families should not have to pay the full cost of treatment out of pocket.

But the details vary significantly from state to state. Some states have no caps on coverage. Others limit benefits by age, dollar amount, or both. Knowing what your state requires helps you understand your rights and advocate for your child’s care.

This guide covers the three main paths to ABA therapy coverage, breaks down the mandate details for every state where Treetop operates, and gives you practical tips for navigating the insurance process.

The Three Paths to ABA Therapy Coverage

Path 1: Medicaid (Best Coverage, No Caps)

If your child is on Medicaid, you have the most comprehensive coverage available. Under the federal EPSDT (Early and Periodic Screening, Diagnostic, and Treatment) provision, Medicaid must cover all medically necessary services for children under 21. This includes ABA therapy.

What EPSDT means for your family:

• $0 copay in most states
• No annual or lifetime dollar caps
• No arbitrary hour limits
• Coverage for assessments, direct therapy, and supervision

EPSDT is a federal requirement, so these protections apply regardless of which state you live in. If your child qualifies for Medicaid, this should be your primary coverage path for ABA therapy.

Path 2: Commercial Insurance (Varies by State Mandate)

If you have employer-sponsored or marketplace insurance, your coverage is governed by your state’s autism insurance mandate. Every state has one, but the specifics differ. Some mandates are generous with no age or dollar limits. Others have caps that may not cover the full cost of intensive therapy.

The table below breaks down the mandate details for each state where Treetop provides services.

Path 3: Military Coverage (TRICARE, Always Covered)

TRICARE covers ABA therapy for all eligible beneficiaries with an autism diagnosis. Active duty family members on TRICARE Prime pay $0 in copays. TRICARE Select members may have cost-sharing after the deductible, but coverage is comprehensive with no arbitrary caps.

State-by-State Insurance Mandate Breakdown

Below is a summary of the autism insurance mandate in every state where Treetop operates. These mandates apply to commercial (private) insurance plans regulated by the state. Self-funded employer plans may follow different rules under federal ERISA guidelines, but many voluntarily follow state mandates.

State	Mandate Law	Age Limit	Annual Cap
Arizona	A.R.S. § 20-826.04 (Steven’s Law)	Under 16	No lifetime cap
Colorado	SB 09-244 / HB 19-1269	No age limit	$34,000/year
Georgia	HB 429 (Ava’s Law)	Under 6	$35,000/year
Maryland	SB 300 / HB 1106	No age limit	No cap
Nevada	AB 162	Under 18 (22 if in school)	$72,000/year
New Mexico	HB 325	No specified limit	$36,000/year
North Carolina	SB 207 (Rylan’s Law)	No age cap	No cap
Oklahoma	HB 2962	Under 9	$25,000 (ind) / $50,000 (group)
Texas	SB 1484	No specified limit	No specific cap
Utah	SB 57	Under 10	$40,000/year
Virginia	HB 2744 / HB 2467	No age limit	No cap

Important note: These caps and limits apply to state-regulated commercial insurance plans. Medicaid coverage through EPSDT has no caps in any state. Self-funded employer plans may have different rules.

What These Mandates Mean for Your Family

If you live in a state with no dollar cap (Maryland, North Carolina, Virginia, Texas), your commercial insurance should cover all medically necessary ABA therapy without hitting a financial limit. These are the strongest mandates in the country.

If your state has an annual cap, that cap applies to the total allowed amount your insurance pays for ABA therapy in a year. Depending on your child’s treatment hours, you may or may not reach the cap. For example, a child receiving 20 hours per week of ABA therapy at $80 per hour would cost roughly $83,000 per year. In a state with a $35,000 cap, you would need a secondary coverage source or reduced hours once the cap is reached.

If your state has an age limit, coverage is required up to the specified age. After that, your insurance may still cover ABA therapy voluntarily, or you may need to transition to Medicaid or other funding sources. Your provider can help you plan for this transition.

Tips for Navigating Insurance Coverage

Get Pre-Authorization

Most insurance plans require pre-authorization before ABA therapy begins. This means your provider submits a treatment plan, and the insurance company reviews it before approving coverage. Your ABA provider handles this process, but it can take 1 to 4 weeks. Start early.

Appeal Denials

If your insurance denies coverage or limits hours below what your BCBA recommends, you have the right to appeal. Common reasons for denial include incomplete documentation, missing diagnosis codes, or the insurer claiming the treatment is not medically necessary.

Many initial denials are overturned on appeal. Your ABA provider can write a letter of medical necessity and help you through the process. Do not accept a denial as the final answer.

Work with Your Provider’s Intake Team

A good ABA provider does not just deliver therapy. They help you navigate insurance from day one. At Treetop, our intake team will:

• Verify your benefits before your child’s first appointment
• Explain your copay, coinsurance, and deductible in plain language
• Handle the pre-authorization process
• Appeal denials on your behalf
• Help you explore secondary coverage options if needed

79% of the children Treetop serves have their ABA therapy fully covered by insurance. Our team knows how to work within the system to maximize your child’s benefits.

Check for Secondary Coverage

If your child has both commercial insurance and Medicaid, Medicaid can serve as a secondary payer to cover copays, coinsurance, and amounts that exceed your commercial plan’s cap. This is common for families whose children qualify for Medicaid based on disability rather than income.

Know Your State’s External Review Rights

If your internal appeal is denied, most states offer an external review process where an independent third party reviews your case. This is a powerful tool, because external reviewers frequently side with families when ABA therapy has been recommended by a qualified BCBA.
