Does Medi-Cal Cover ABA Therapy? What California Parents Should Know
Yes. Medi-Cal covers ABA therapy as part of a benefit called Behavioral Health Treatment (BHT) for members under 21 when a physician or psychologist determines it is medically necessary. If your child is in a Medi-Cal managed care plan, such as CalOptima Health in Orange County, you get BHT through that plan, so the plan is your first call.
Key takeaways
- Medi-Cal’s Behavioral Health Treatment benefit includes ABA for eligible members under 21.
- Only a physician or a psychologist can determine that BHT is medically necessary.
- Most families in managed care get ABA through their Medi-Cal health plan, which handles referrals and authorization.
- Commercial plans in California also cover behavioral health treatment for autism, but details vary. Always confirm with your plan.
- You do not have to sort this out alone. A provider’s intake team can help you gather what the plan needs.

What Medi-Cal covers for ABA therapy
The California Department of Health Care Services (DHCS) runs Medi-Cal. Its Behavioral Health Treatment page explains that BHT services, including ABA, are covered for eligible Medi-Cal members under 21. That includes children with autism spectrum disorder. It also includes children for whom a physician or psychologist determines BHT is medically necessary, regardless of diagnosis.
In plain terms, three things usually need to line up:
| Requirement | What it means for your family |
|---|---|
| Your child has Medi-Cal and is under 21 | Check that your child’s Medi-Cal is active. Renewal paperwork matters here. |
| A physician or psychologist says ABA is medically necessary | This is often a pediatrician, developmental pediatrician, or psychologist. |
| The service goes through the right channel | Most families go through their Medi-Cal health plan. Others use fee-for-service options. |
If you are new to ABA, our guide on what ABA therapy is explains the basics. The short version: ABA is a structured, individualized approach that helps children build skills in areas like communication, daily living, and play. It is one of several behavioral approaches the CDC describes for autism.
Managed care vs. fee-for-service Medi-Cal
How your child receives ABA depends on how your child’s Medi-Cal is set up.
If your child is in a Medi-Cal managed care plan
DHCS states that members in a Medi-Cal managed care plan receive BHT services from their plan. Your plan decides which providers are in network, what paperwork it needs, and how authorization works.
In Orange County, many Medi-Cal members are enrolled in CalOptima Health. CalOptima describes itself as a county organized health system and lists Behavioral Health Treatment, including ABA, among its Medi-Cal behavioral health services. Your child’s member ID card shows which plan they have.
If your child has fee-for-service Medi-Cal
Some children have “fee-for-service” Medi-Cal instead of a managed care plan. DHCS says these members historically received BHT through their local regional center. As of July 1, 2025, they also have the option to receive BHT from enrolled Medi-Cal Qualified Autism Service (QAS) providers instead of through the regional center.
If you are not sure which type your child has, call the number on the back of their Medi-Cal card and ask.
How to get started with Medi-Cal ABA therapy
Every plan runs a little differently, but most families move through the same general steps.
Step 1: Get a diagnosis or a recommendation
Your plan will want to see that a physician or psychologist has found ABA to be medically necessary. For many families, that starts with an autism diagnosis. The CDC notes that a diagnostic evaluation may involve a developmental pediatrician, child psychologist, speech-language pathologist, and/or occupational therapist.
If your child has not been evaluated yet, our article on when to get an autism evaluation walks through who diagnoses autism and how to prepare.
Keep copies of:
- The diagnostic report or evaluation summary
- Any written recommendation for ABA or Behavioral Health Treatment
- Your child’s Medi-Cal ID card (front and back)
- Recent school or early intervention reports, if you have them
Step 2: Contact your health plan
Call your plan’s member services or behavioral health line. For CalOptima Health members, the plan lists a Behavioral Health Line at 1-855-877-3885 (TTY 711) and Medi-Cal Customer Service at 1-888-587-8088.
Questions to ask:
- “Is Behavioral Health Treatment, including ABA, a covered benefit for my child?”
- “What documents do you need from my child’s doctor or psychologist?”
- “Do I need a referral, or can I contact an ABA provider directly?”
- “Which ABA providers near me are in network?”
- “Is there a case number or reference number for this call?”
Write down the date, the name of the person you spoke with, and what they told you. It saves time later.
Step 3: Referral and authorization
Many plans require authorization before services begin. This usually means the ABA provider completes an assessment, a Board Certified Behavior Analyst (BCBA) writes a treatment plan with goals, and the provider sends it to the plan for approval.
Ongoing services may need to be re-authorized over time, often with progress updates from the BCBA. Ask your plan how its process works so there are no surprises.
Step 4: Provider intake
Once you choose a provider, the intake team will gather your paperwork, check your coverage, and schedule the assessment. This is a good time to ask about setting (clinic, home, or school), scheduling, and how parents are involved.
Our guide on how to choose an ABA provider has a full list of questions to bring to that first call.
Keeping services on track once they start
Getting approved is a big step. A few habits help keep services running smoothly afterward.
- Keep Medi-Cal active. Watch your mail for renewal packets and return them on time. A lapse in coverage can pause services.
- Report changes. Tell your plan and your provider if you move, change phone numbers, or switch plans.
- Save every letter. Keep authorization approvals, denials, and plan notices together, with the dates they arrived.
- Note the end date. Authorizations usually cover a set period. Ask your provider when the current one ends and what the plan needs to renew it.
- Stay involved in progress reviews. Your child’s BCBA will update goals over time. Your input about what matters at home helps shape the next plan.
If something changes with your coverage, let your provider know right away. It is much easier to solve a paperwork problem early than after sessions have stopped.
What about commercial insurance in California?
Many families have private or employer health insurance instead of, or along with, Medi-Cal. The California Department of Managed Health Care (DMHC) states on its behavioral health care page that California law requires all plans to cover behavioral health treatment for autism or pervasive developmental disorder.
That said, the details still vary from plan to plan. Things that commonly differ include:
- Which providers are in network
- What documents are needed to start services
- Whether prior authorization is required, and how often it is renewed
- Copays, coinsurance, and deductibles
Call the member services number on your card and ask the same questions listed above. If your child has both commercial insurance and Medi-Cal, ask each plan how they coordinate benefits and which plan should be billed first. Share both cards with your provider’s intake team.
If a claim or authorization is denied
A denial is frustrating, but it is not always the final answer. Common reasons include missing paperwork, an expired authorization, or a provider who is out of network.
What you can do:
- Ask for the reason in writing. You need to know exactly what the plan decided and why.
- Talk with your child’s doctor and ABA provider. Sometimes a missing report or updated treatment plan resolves the issue.
- Follow the plan’s complaint process. The DMHC says that if you disagree with your plan’s response or your plan denies treatment, you can file a complaint with your plan.
- Get outside help. The DMHC Help Center is at 1-888-466-2219. For Medi-Cal behavioral health concerns, the DMHC also lists the Medi-Cal Mental Health Care Ombudsman at (800) 896-4042.

Frequently asked questions
Does my child need an autism diagnosis for Medi-Cal to cover ABA?
Not always. The California Department of Health Care Services says Behavioral Health Treatment is covered for members under 21 with autism spectrum disorder and for children whose physician or psychologist determines it is medically necessary, regardless of diagnosis. In practice, your health plan will tell you exactly what paperwork it needs before it approves services.
Who decides whether ABA therapy is medically necessary under Medi-Cal?
According to DHCS, only a physician or a psychologist can determine that Behavioral Health Treatment is medically necessary. That is often your child's pediatrician, a developmental pediatrician, or a psychologist who has evaluated your child.
My child has Medi-Cal through CalOptima Health. Who do I call about ABA?
Start with CalOptima Health. Its Behavioral Health Line is 1-855-877-3885 (TTY 711), and Medi-Cal Customer Service is 1-888-587-8088. Ask how Behavioral Health Treatment is authorized and which providers are in network.
What can I do if my health plan denies ABA therapy?
Ask the plan for the reason in writing and follow its complaint or grievance process. The California Department of Managed Health Care Help Center (1-888-466-2219) can help if you disagree with your plan's decision. For Medi-Cal behavioral health issues, the DMHC also lists the Medi-Cal Mental Health Care Ombudsman at (800) 896-4042.
