Insurance & Funding

Insurance, Medicaid waivers, and how to actually get paid for.

The U.S. patchwork of autism coverage is genuinely confusing. This guide breaks down private insurance, Medicaid waivers, SSI, and what to do when a claim is denied.

Autism insurance mandates

States have autism insurance mandates, but they cover different things, different ages, and different plan types. Check yours. Three things matter for your specific plan:

  • Fully insured (your employer buys a plan from a carrier) — state mandate usually applies.
  • Self-funded / ERISA (employer pays claims themselves; common at large employers) — state mandate does not apply, but ACA and federal mental health parity do.
  • Medicaid — EPSDT can cover medically necessary services for children under 21, including ABA. What is actually authorized depends on your state.

Find out which kind of plan you have.

Call HR or member services and ask: "Is this plan fully insured or self-funded?" The answer changes everything that follows.

What insurance typically covers

  • Diagnostic evaluation (developmental pediatrician, neuropsych)
  • ABA therapy — almost always requires the autism diagnosis on file
  • Speech-language therapy
  • Occupational therapy
  • Physical therapy
  • Mental health (therapy, psychiatry)
  • AAC devices — usually through DME, often with a speech eval. See Communication & AAC.

Prior authorization — the gatekeeper

Nearly every autism service requires prior auth. Your provider files it; you should still track it. Typical flow:

  1. Diagnostic report submitted
  2. Treatment plan (with hours, goals, location) submitted
  3. Insurance reviews the request. The clock is set by your plan — ask for the deadline in writing. Urgent requests are often faster than standard ones.
  4. If approved, it is for a set period. Ask when it expires.
  5. Renewal: provider must show progress data

If you're denied — read this slowly

Denial does not mean no. Some appeals succeed when the file is complete, and some do not. We don't have a number for how often that happens. Read the denial, and don't assume an appeal will win.

  • Read the Explanation of Benefits (EOB) — note the denial code and reason.
  • Request the full claim file and the specific medical-necessity criteria they used.
  • File the internal appeal before the deadline on the denial letter. Plans differ. Get that date in writing.
  • If denied again, file external review — independent reviewer, often free, binding.
  • For ERISA plans, you can file with the Department of Labor. For state-regulated plans, your state insurance commissioner.

To Whom It May Concern,

I am appealing the denial of [Service / CPT codes] for my child [Child's name] (DOB [DOB], Member ID [Member ID], Claim # [Claim #]) dated [Denial date]. This denial is inconsistent with my plan's medical-necessity criteria for the following reasons:

(1) My child has a confirmed diagnosis of Autism Spectrum Disorder (DSM-5 F84.0) made by [Diagnosing provider].
(2) The recommended treatment plan from [Treating clinician] is the standard of care per APA, AAP, and Council of Autism Service Providers guidelines.
(3) Without these services my child is at documented risk of regression in: [Skills at risk of regression].

I request a full overturn and approval. I have attached the diagnostic report, the treatment plan, and supporting clinical letters. Please respond in writing within the time required by my plan, and provide the specific medical-necessity criteria and reviewer credentials used.

Sincerely,
[Your name & contact]

Medicaid HCBS waivers — the most underused tool

A Home and Community-Based Services (HCBS) waiver lets your child qualify for Medicaid based on their own income and disability, ignoring parental income. That unlocks therapies,respite, supported employment, and more — even if you have private insurance.

  • Every state has different waivers with different names (DD waiver, ID waiver, autism waiver, Katie Beckett, TEFRA).
  • Many have waitlists, and in some states those lists run for years. Lengths change. Ask your state agency for the current wait, and get on the list today even if you're not sure you need it.
  • Use our Resource Finder to find your state's intake office.

Waitlists are real, and some are long.

Some states' lists run for many years. Ask the agency for the current wait for the waiver you want. Get on the list the same week you get a diagnosis — you can always decline later.

TEFRA / Katie Beckett option

Some states offer a "Katie Beckett" or TEFRA pathway: Medicaid eligibility for disabled children based on the child's own income, which is often little or none. Some of these pathways do not use a waitlist, and some do. Ask your state. It can be a large help, and it can be worth applying even if you have private insurance.

SSI for children with disabilities

Supplemental Security Income (SSI) is a federal monthly cash benefit for children with qualifying disabilities. It's means-tested on household income, so many two-earner families won't qualify — but in many states, SSI eligibility also opens automatic Medicaid. Apply at ssa.gov. Adult SSI, ABLE accounts, and special needs trusts are covered in SSI, ABLE & trusts.
