Does My State ABA Therapy Law Even Apply to Me? The ERISA Loophole Explained

Why "My State Requires ABA Coverage" Doesn't Always Protect You

Every year, more families search for their state's autism insurance mandate, find a reassuring law that requires health plans to cover Applied Behavior Analysis (ABA) therapy, and assume they're covered. Then a claim gets denied, and they find out their employer's health plan doesn't have to follow that state law at all.

The reason is a federal law called ERISA, and understanding it can be the difference between a denied claim and a successful appeal.

What ERISA Self-Funded Plans Are, in Plain English

Most large employers don't actually buy health insurance from an insurance company. Instead, they "self-fund" their health plan: the employer pays employees' medical claims directly out of its own budget, and often hires an insurance company (like UnitedHealthcare, Cigna, Aetna, or Blue Cross Blue Shield) only to administer the plan and process claims on its behalf.

That distinction matters enormously for autism coverage. Under the federal Employee Retirement Income Security Act (ERISA), self-funded employer health plans are exempt from state insurance laws, including the state autism/ABA therapy mandates that most parents rely on. According to KFF's annual employer health benefits survey, roughly two-thirds of covered workers at U.S. employers are enrolled in a self-funded plan, so this isn't a rare loophole. It's the reality for the majority of privately insured working families.

By contrast, a "fully insured" plan, one where the employer actually purchases a policy from an insurance company, must follow your state's insurance laws, including any ABA therapy mandate.

How to Tell Which Kind of Plan You Have

• Ask your HR or benefits department directly: "Is our health plan self-funded/self-insured, or fully insured?" This is the fastest, most reliable answer.
• Check your Summary Plan Description (SPD): Self-funded plans are required to disclose this. Look for language like "the Plan is self-funded" or "the Employer is the Plan Sponsor and bears the risk of claims."
• Look at your insurance card: A logo from a major insurer does not tell you whether the plan is self-funded. Insurers administer both fully insured and self-funded plans, so the card alone isn't proof either way.
• Government and church employers: Many public-sector and religious-organization plans are also exempt from ERISA entirely, and may or may not be subject to your state's mandate depending on how the plan is structured. Ask directly.

The Good News: ERISA Exemption Isn't a Complete Shield

Being self-funded doesn't mean a plan can do whatever it wants when it comes to autism and ABA therapy. Self-funded plans are still bound by federal law, most importantly the Mental Health Parity and Addiction Equity Act (MHPAEA).

MHPAEA doesn't force a plan to cover autism or ABA therapy. But if a plan does cover mental health and behavioral health conditions generally, it cannot single out one specific mental health condition, like autism, for a treatment limitation that doesn't apply to comparable medical or surgical care.

That principle was tested directly in Doe v. United Behavioral Health, decided by the U.S. District Court for the Northern District of California in March 2021. The self-funded employer plan in that case covered autism spectrum disorder generally but carved out a specific exclusion for "Intensive Behavioral Therapies such as Applied Behavior Analysis." The court ruled that carve-out violated the Parity Act: a plan may lawfully exclude an entire condition from coverage, but once it agrees to cover a condition, it cannot then exclude a specific, medically standard treatment for that condition while covering comparable treatments for physical conditions. The plan's ABA exclusion was struck down.

The case is now several years old, but its logic still applies today. The Department of Labor's own reporting to Congress has identified plan limitations or exclusions on autism treatment as among the most common MHPAEA violations found in its investigations, and DOL enforcement has led some self-insured plans to remove ABA exclusions entirely.

What This Means If Your ABA Claim Was Denied

If you've been told "our plan doesn't cover ABA therapy" or "we're self-funded, so the state mandate doesn't apply to us," that may be legally accurate, but it isn't necessarily the end of the story. Here's how to approach it:

1. Confirm your plan type first. Don't assume; get it in writing from HR or the Summary Plan Description.
2. Read the exclusion language carefully. Does the plan exclude autism as a condition entirely, or does it cover autism generally but specifically carve out ABA therapy or "intensive behavioral therapies"? The second scenario is the one that ran into trouble in Doe v. United Behavioral Health.
3. Request the plan's Mental Health Parity comparative analysis. Since 2021, MHPAEA amendments require plans to document, in writing, that any treatment limitation on mental health benefits is comparable to limitations on medical/surgical benefits. Plans must provide this analysis to plan members or regulators on request; a plan that can't produce one is on shaky legal ground.
4. File a formal appeal citing MHPAEA, not just the state mandate, since the state law won't apply to a self-funded plan. Reference the plan's general behavioral health coverage and ask how the ABA exclusion is comparable to any limitation on medical/surgical treatment.
5. Escalate to the Department of Labor's Employee Benefits Security Administration (EBSA) if the internal appeal is denied. EBSA investigates MHPAEA parity complaints against ERISA plans and has identified autism-related treatment limitations as a recurring enforcement focus.
6. Check for EPSDT or Medicaid backup coverage if your child also qualifies for Medicaid (including through a state's Katie Beckett/TEFRA option), since EPSDT requires coverage of medically necessary ABA therapy for children regardless of your employer plan's terms.

Why This Matters More Than Ever in 2026

As states across the country tighten their own Medicaid ABA rules and insurance mandates this year, families are increasingly discovering that their employer's self-funded plan was never subject to those state protections in the first place. Understanding the ERISA distinction early, before a denial happens, can save months of confusion and help you build the right appeal from day one instead of citing a state law that simply doesn't apply to your plan.

If your child's ABA therapy claim has been denied and you're not sure where to start, a good first step is talking to your prospective or current provider's billing team, who deal with these denials regularly and can often tell you quickly whether your plan is self-funded and what the realistic appeal path looks like.
