How to Get ABA Therapy Covered by Insurance: A Step-by-Step Guide

To get ABA therapy covered by insurance, start with an autism diagnosis or a referral from a physician or psychologist, then call your health plan to confirm its behavioral health benefits and authorization rules. From there, you choose an in-network ABA provider, the plan approves an assessment, and the plan reviews the treatment plan before regular sessions begin. Most plans review progress and reauthorize services periodically.

Key takeaways

• Most plans follow a similar path: diagnosis or referral, benefits check, assessment authorization, treatment authorization, and reauthorization.
• California’s Department of Managed Health Care states that state law requires plans to cover behavioral health treatment for autism, but details vary by plan.
• Authorization is not a promise to pay for every hour, and cost sharing may still apply.
• Keep a folder of every report, letter, and reference number. It saves time later.
• You do not have to do this alone. Many providers, including ours, help families with coverage and authorization.

Does insurance cover ABA therapy?

Often, yes, but it depends on your plan. The California Department of Managed Health Care (DMHC) states on its behavioral health care page that California law requires plans to cover behavioral health treatment for autism or pervasive developmental disorder. Behavioral health treatment (BHT) is the term many California plans use for services such as ABA.

For children with Medi-Cal, the California Department of Health Care Services (DHCS) says on its BHT page that Medi-Cal covers all medically necessary BHT services, including ABA, for eligible members under 21. Our guide to Medi-Cal coverage for ABA therapy walks through the Medi-Cal details.

Even when ABA is a covered benefit, your plan decides how many hours it approves, which providers you can use, and what you pay. Not every plan is overseen by the same agency, so ask your plan which rules apply to you.

Step-by-step: how to start ABA through insurance

The exact order can differ by plan, but most families go through these steps.

Step 1: Get a diagnosis or referral

Most plans want documentation before approving ABA. This is often an autism diagnosis report, a referral or prescription from your child’s doctor, or both. The CDC explains that autism is diagnosed by looking at a child’s development and behavior, often by specialists such as developmental pediatricians or child psychologists.

For Medi-Cal, DHCS states that only a physician or a psychologist can determine that BHT is medically necessary. If you are still waiting on an evaluation, our article on when to get an autism evaluation can help you plan.

Ask for a copy of the full diagnostic report, not only a summary. Plans often want to see the details.

Step 2: Check your child’s behavioral health benefits

Call the member services number on your insurance card. Ask specifically about “behavioral health treatment” or “ABA therapy” benefits for your child. Write down the date, the name of the person you spoke with, and a call reference number. A list of questions to ask is below.

Step 3: Choose an in-network ABA provider

A provider is in network when it has a contract with your plan. Going out of network can cost more or may not be covered at all. Ask your plan for its list of in-network ABA providers, then confirm with the provider directly. For tips on comparing providers, see how to choose an ABA provider.

Step 4: Get the assessment authorized

Many plans require prior authorization before an ABA assessment. HealthCare.gov defines preauthorization as a decision by your plan that a service or treatment plan is medically necessary, and notes it is not a promise the plan will cover the cost. Your provider usually submits this request with your child’s diagnosis and referral.

Step 5: Complete the assessment and treatment plan

Once approved, a Board Certified Behavior Analyst (BCBA) meets your child and family, observes, and gathers information about strengths, needs, and daily routines. The BCBA then writes a treatment plan: a document that lists your child’s goals, how they will be taught, and how many hours of therapy the BCBA recommends.

Step 6: Get treatment authorized

The provider sends the treatment plan to your plan for review. The plan may approve the requested hours, approve fewer hours, or ask for more information. Ask the provider to share the authorization letter with you so you know the approved hours and dates.

Step 7: Start services

Once treatment is authorized, sessions can be scheduled. Depending on your plan and provider, this may include in-home sessions, center-based sessions, or parent training. Learn more about in-home ABA therapy and what it looks like for families.

Step 8: Reauthorization and progress reports

Authorizations usually cover a set period. Before it ends, the BCBA writes a progress report with updated data and goals, and the plan decides whether to continue, change, or end services. Plans set their own review schedules. Our article on how long ABA therapy lasts explains how goals and hours tend to change over time.

Questions to ask your insurance provider about ABA

Copy this checklist into your phone or notebook before you call.

Coverage

• Does my child’s plan cover ABA or behavioral health treatment?
• Is a diagnosis, referral, or prescription required? From whom?

Network

• Which ABA providers near me are in network?
• Are in-home sessions covered, as well as center-based sessions?
• What happens if I choose an out-of-network provider?

Authorization

• Does the assessment need prior authorization? Does treatment?
• Who submits the request: me, my doctor, or the provider?
• How long do decisions usually take, and how will I be told?
• How often must services be reauthorized?

Documents to keep in your ABA insurance folder

Document	Why it matters
Diagnostic report	Most plans need it to approve ABA
Referral or prescription	Some plans require it before an assessment
Insurance card (front and back)	Providers need member and group numbers
Call log with names and reference numbers	Helps if information conflicts later
Authorization letters	Shows approved hours and dates
Treatment plan and progress reports	Needed for reauthorization and appeals
Explanation of benefits statements	Shows what the plan paid and what you owe

What if your claim or authorization is denied?

A denial can feel discouraging, but it is not always the final word.

1. Ask for the reason in writing. Sometimes a denial is about missing paperwork, not eligibility.
2. Talk with your provider. They may be able to send more information or ask the plan how to request a review of the decision.
3. File a grievance with your plan. The DMHC says on its complaint page that you generally need to go through your plan’s grievance process for 30 days before filing a complaint with the DMHC.
4. Ask about an Independent Medical Review (IMR). According to the DMHC, if your plan denies, changes, or delays a requested service, you may be able to apply for an IMR. The DMHC Help Center can be reached at 1-888-466-2219.
