Does Medi-Cal Cover ABA Therapy in California?
If your child has Medi-Cal and you have been told they may benefit from ABA therapy, the first question is usually the simplest: is it covered? The short answer is yes, in full, for children and young adults under 21. This guide explains what the benefit actually includes, who qualifies, how hours are decided, which plan handles it in your county, and what your rights are if a request is denied.
Key takeaways
- Medi-Cal covers ABA therapy as Behavioral Health Treatment (BHT) for members under 21, with no copays, deductibles, or out-of-pocket cost.
- A formal autism diagnosis is not required. A physician or psychologist only needs to determine that ABA is medically necessary.
- Hours are not fixed by Medi-Cal. They come from your provider's assessment, and the plan is reviewed at least every six months.
- Your Medi-Cal managed care plan (Partnership HealthPlan, Contra Costa Health Plan, Alameda Alliance, Kaiser, and others) authorizes and pays for the services.
- If a request is denied or cut, you have 60 days to appeal and can ask for a State Hearing after that.
The short answer
Yes. Under California law and the federal Medicaid rules Medi-Cal follows, Applied Behavior Analysis is a covered benefit for Medi-Cal members under age 21. Medi-Cal groups ABA with other evidence-based approaches under one name, Behavioral Health Treatment, and it is provided through your child's Medi-Cal managed care plan rather than through the regional center.
The benefit exists because of the federal Early and Periodic Screening, Diagnostic and Treatment (EPSDT) rule, which requires state Medicaid programs to cover any medically necessary service for members under 21. In practice that means the question is never "does Medi-Cal cover ABA" but "is ABA medically necessary for my child right now," and that is a clinical decision, not a coverage one.
What the Medi-Cal ABA benefit includes
Behavioral Health Treatment is not a single service. When your child's plan authorizes BHT, it is approving a package that your ABA provider delivers and documents. The Department of Health Care Services' policy for managed care plans (All Plan Letter 23-010) spells out the pieces:
- An initial assessment. A Board Certified Behavior Analyst (BCBA) or other qualified autism service provider evaluates your child, usually in your home, and identifies the skills and behaviors to work on.
- A written treatment plan. Measurable goals, the number of hours requested, who will deliver them, how parents will be involved, and the criteria for reducing or ending services. This is the document your plan uses to authorize care.
- Direct one-on-one therapy. Sessions with a behavior technician, at home or in the community, at the frequency in the plan.
- Ongoing BCBA supervision. The BCBA observes sessions, reviews the data, and adjusts the program.
- Parent and caregiver training. Coaching so the strategies that work in session keep working when the therapist leaves. Medi-Cal treats family participation as part of the treatment, not an optional extra.
- Progress reports and re-evaluation. Your provider measures progress continuously and re-evaluates the plan at least every six months, which is also when the plan re-authorizes hours.
Who is eligible
Your child qualifies for ABA through Medi-Cal when three things are true:
- They are under 21 and enrolled in Medi-Cal (full-scope coverage, which is what nearly all children have).
- A licensed physician, surgeon, or licensed psychologist has determined that Behavioral Health Treatment is medically necessary and recommended it. Your pediatrician can do this.
- The treatment is delivered by a qualified provider that contracts with your Medi-Cal plan.
A diagnosis is not required
This is the point families most often get wrong, sometimes because they were told otherwise years ago. Before 2018, Medi-Cal limited BHT to children with an autism spectrum disorder diagnosis. Since then, DHCS has required plans to cover BHT for any member under 21 for whom a physician or psychologist finds it medically necessary, with or without an autism diagnosis. If your child is on a long waitlist for a diagnostic evaluation, that wait does not have to delay ABA.
An evaluation is still worth pursuing. It unlocks regional center eligibility, informs your child's IEP, and gives your provider a fuller picture. Our guide on getting an autism evaluation in California walks through the four routes.
How many hours will Medi-Cal cover?
Medi-Cal does not publish a cap. The number of hours comes from your provider's assessment and treatment plan, and the plan approves what is medically necessary for your child, not what is typical for their age. The Behavior Analyst Certification Board's practice guidelines describe two broad models that most plans recognize:
- Focused treatment targets a limited set of goals, such as communication or a specific challenging behavior, and commonly runs 10 to 25 hours per week.
- Comprehensive treatment works across many developmental areas at once (communication, social skills, daily living, and behavior) and commonly runs 30 to 40 hours per week.
Two things affect the hours you actually receive more than the authorization itself. First, your family's availability: a plan can authorize 20 hours, but sessions only happen in the windows your child and a caregiver are consistently home. Second, staffing in your area. Families with wide, regular availability are easier to schedule and tend to reach their authorized hours faster. Our guide on preparing your home and schedule explains how to set that up.
Which Medi-Cal plan handles ABA in your county
Medi-Cal is delivered through county-based managed care plans, and every one of them is required to cover BHT. The plan name on your child's card tells you who authorizes services. In the counties Behavia serves:
- Partnership HealthPlan of California: Marin, Solano, Napa, Sonoma, Yolo, and other North Bay and Northern California counties. See our Partnership HealthPlan ABA guide.
- Contra Costa Health Plan (CCHP): Contra Costa County.
- Alameda Alliance for Health: Alameda County, including Fremont and Hayward.
- Kaiser Permanente: Kaiser's Medi-Cal plan in the counties where it operates, including much of the Bay Area and Sacramento region.
- Health Net, Molina, Anthem Blue Cross, and Health Plan of San Joaquin: Sacramento, San Joaquin, and Stanislaus counties, depending on the plan your family chose at enrollment.
Behavia accepts Medi-Cal through Partnership HealthPlan, Contra Costa Health Plan, Alameda Alliance, and Kaiser. If your card shows a different plan, contact us and we will tell you honestly whether we can serve your child or point you to someone who can. Our Medi-Cal ABA therapy page has the current list.
Medi-Cal vs. the regional center: who pays for what
Many North Bay and Solano families first hear about ABA from a regional center service coordinator, so it is worth being clear about the roles. Regional centers (Golden Gate Regional Center in Marin, North Bay Regional Center in Solano, Napa, and Sonoma) provide Early Start services for children under three and Lanterman Act services for eligible children and adults. They are the payer of last resort: when a service is available through your child's health plan, the plan pays first.
For a Medi-Cal member, that means ABA is authorized and paid by the Medi-Cal plan, and the regional center coordinates around it. The regional center may still fund services the plan does not cover, help with respite, or provide behavioral support for a child under three who is not yet receiving BHT through Medi-Cal. Tell your provider about your regional center coordinator; with your permission we coordinate directly.
What it costs
Nothing. For full-scope Medi-Cal members under 21 there are no copays, no deductibles, and no coinsurance for BHT. Families are never billed for the assessment, the sessions, supervision, or parent training. If a provider asks you to pay out of pocket for a service Medi-Cal covers, that is a red flag, and you can report it to your plan or to the Medi-Cal Managed Care Ombudsman.
What to do if a request is denied or hours are reduced
Denials and reductions happen, most often because a treatment plan is missing a required element or the plan wants updated data. You have real rights here, and the clock matters.
Read the Notice of Action
Your plan must send a written notice explaining what was denied or changed and why. Keep it. The date on it starts your appeal window.
File an appeal with your plan within 60 days
You can appeal by phone or in writing; the member services number is on the card. Ask your ABA provider to submit updated progress data and a letter of medical necessity. If you file within 10 days of the notice and the services were already approved, ask for them to continue during the appeal.
Request a State Hearing if the appeal is denied
After the plan decides your appeal, you can request a State Hearing through the California Department of Social Services. You have 120 days from the appeal decision. For medical necessity disputes you can also ask the Department of Managed Health Care for an Independent Medical Review.

Disability Rights California publishes free guides on ABA appeals, and the Medi-Cal Managed Care Ombudsman can intervene when a plan is not following the rules. Your provider should be doing most of the paperwork; you should never feel alone in the process.
How to start ABA therapy with Medi-Cal
Once you know your child is covered, starting is a short list:
- Confirm your child's Medi-Cal coverage is active and note the plan on the card.
- Ask your pediatrician (or a licensed psychologist) to recommend Behavioral Health Treatment.
- Choose a provider that contracts with your plan and serves your area, then let them handle the authorization.
- Share your family's real weekly availability so the assessment and sessions can be scheduled consistently.

Frequently asked questions
- Does Medi-Cal cover ABA therapy in California?
- Yes. Medi-Cal covers ABA therapy as part of its Behavioral Health Treatment (BHT) benefit for members under 21 when a physician or psychologist finds it medically necessary. There are no copays, deductibles, or out-of-pocket costs for eligible children.
- Does my child need an autism diagnosis to get ABA through Medi-Cal?
- No. Since 2018, California's Department of Health Care Services has required Medi-Cal plans to cover BHT for members under 21 with or without an autism diagnosis, as long as a licensed physician or psychologist determines it is medically necessary. An evaluation is still valuable for school services and for understanding your child, but it is not a gate to starting ABA.
- How many hours of ABA therapy will Medi-Cal cover?
- There is no fixed number. Hours are set by the assessment and treatment plan your provider submits, based on what is medically necessary for your child. Focused treatment plans commonly run 10 to 25 hours per week and comprehensive plans 30 to 40 hours, and the plan is reviewed at least every six months.
- Which Medi-Cal plan covers ABA in my county?
- Every Medi-Cal managed care plan in California must cover BHT. In Behavia's service area that includes Partnership HealthPlan of California (Marin, Solano, Napa, Sonoma, Yolo, and other North Bay and Northern California counties), Contra Costa Health Plan, Alameda Alliance for Health, and Kaiser Permanente's Medi-Cal plan. Your plan name is printed on your child's Medi-Cal card.
- What can I do if Medi-Cal denies or reduces ABA hours?
- You have appeal rights. You can file an appeal with your Medi-Cal plan within 60 days of the written notice, and if the plan upholds the decision you can request a State Hearing. Services that were already approved can often continue during the appeal if you file quickly. Your ABA provider can help you gather the documentation.
