Does Medicaid Cover ABA Therapy?
Yes, when it's medically necessary. Federal rules require every state's Medicaid to cover needed autism treatment for children under 21, and Nevada and Nebraska Medicaid both cover ABA. Alpaca Health accepts Medicaid in Nevada and Nebraska, checks your benefits for free, and handles the approval paperwork with your BCBA.
How Medicaid covers ABA therapy
Every state's Medicaid must cover autism care that's medically necessary (needed for your child's condition) for children under 21, and each state sets its own ABA rules.
- The federal rule: EPSDT (Medicaid's benefit for members under 21) requires states to cover the treatment a child needs, and a 2014 federal bulletin applied that rule to autism.
- States set the details: CMS, the federal Medicaid agency, doesn't require ABA by name, so each state decides how coverage works, as its ABA toolkit notes.
- Nevada: Nevada Medicaid has covered ABA at any age since April 2024 under its ABA policy, and Nevada Check Up, the state's Children's Health Insurance Program, follows the same ABA rules.
- Nebraska: Nebraska Medicaid covers ABA from birth through age 20, and nearly all members get their care through one of three Heritage Health plans.
- Other states: Families in Texas, Colorado, Hawaii, or North Carolina can read the rules for Texas Medicaid, Health First Colorado, Med-QUEST, and NC Medicaid.
What your child needs to qualify
1. Active Medicaid at a covered age
Your child needs active Medicaid. Nebraska covers ABA through age 20, while Nevada sets no age limit.
2. An autism diagnosis or a related condition
In Nevada, a clinician signs a form confirming the diagnosis and the test used, such as the ADOS-2 (a play-based autism assessment). Nebraska also covers ABA for an intellectual or developmental disability when an assessment shows the need.
3. A clinician's sign-off
Nevada needs a written order from a doctor, physician assistant, nurse practitioner, or psychologist. In Nebraska, a licensed clinician's interview from the past 12 months must show your child needs an ABA assessment.
4. An assessment and treatment plan
A BCBA tests your child's skills and writes a treatment plan with measurable goals for your child and for parent training. The plan has to show why your child needs ABA.
5. A licensed BCBA who takes Medicaid
Both states license BCBAs, and Nebraska has required the license since January 1, 2025. Behavior technicians (RBTs) can run some sessions, and Nebraska's ABA rules require the BCBA to supervise them.
How prior authorization works with Medicaid
This step means getting Medicaid's approval before ABA therapy starts. In Nevada, the state reviews requests for children without a health plan, and each health plan reviews requests for its own members. Nebraska families get approval from their Heritage Health plan.
- What gets sent: The BCBA sends the assessment and treatment plan, and Nevada's first request adds the signed diagnosis form, which isn't repeated later.
- Parents sign in Nevada: You sign the request form and agree to take part in training and keep appointments.
- Up to six months in Nevada: Each approval can last up to 180 days, and each reauthorization (a renewed approval) reports your child's progress over the past 90 days.
- Nebraska approvals vary: Approval length depends on your child's needs, and the BCBA updates the treatment plan at least every 90 days.
- Parent training in Nebraska: Parents are expected to join 1 to 4 hours of training a month, based on how much therapy a child gets, though ABA can't be denied only because a parent can't take part.
- Step 1DiagnosisA licensed clinician confirms autism or a related condition.
- Step 2AssessmentA BCBA tests your child's skills, with no Medicaid approval needed first in Nevada.
- Step 3Treatment planThe BCBA writes measurable goals for your child and for parent training.
- Step 4Medicaid approvalMedicaid or your child's health plan approves the weekly hours.
- Step 5Progress reviewsProgress data goes back to Medicaid before each renewal.
What Medicaid covers for ABA therapy
Your child's BCBA asks for hours under the billing codes (CPT codes) below. Nevada and Nebraska Medicaid cover all of them.
- Assessments (97151, 97152): The BCBA tests your child's skills and plans treatment, sometimes with a technician's help.
- One-to-one therapy (97153): A behavior technician works with your child under the BCBA's direction.
- BCBA supervision (97155): The BCBA joins sessions to adjust the plan, and Nebraska requires the BCBA to observe at least 10% of therapy hours.
- Caregiver training (97156): Coaching for parents and caregivers, with or without your child in the room.
- Group sessions (97154, 97158): Small groups of children when the treatment plan calls for them.
Your child's BCBA recommends weekly hours in the treatment plan. In Nevada, the billing guide lists 15 to 25 hours a week when ABA targets a few behaviors, and 25 to 40 for programs that work on many skills. Nebraska's limit is 6 hours a day and 20 a week, but both states can approve more when records show the need.
What families pay with Medicaid
Covered ABA usually costs your family nothing. Federal rules bar copays and premiums for most children under 18 on Medicaid.
- No bills for covered care: Under Nevada's member rules, providers can't bill you for covered services, leftover balances, or missed appointments, and Nebraska asks families to call their health plan right away about any bill.
- Nevada Check Up premiums: Families with a child on Nevada Check Up may owe a quarterly premium.
- Other insurance pays first: A private plan is billed before Medicaid, and in Nevada a provider can't charge you that plan's copay or deductible (what you pay each year before a plan starts paying) for a Medicaid-covered service.
- Care outside the rules: You may owe for care Medicaid doesn't cover, such as hours above the approved limit, and Nevada providers need your signed agreement before giving that care.

- Approval paperwork: Your BCBA writes the assessment and treatment plan Medicaid reviews, and we handle the submission.
- A BCBA who takes your plan: We look for an independent BCBA who accepts your child's Medicaid plan.
Does Medicaid cover ABA therapy for adults?
It depends on your state. EPSDT stops at age 21, so covering adults is each state's choice. Adults can get ABA through Nevada Medicaid, but Nebraska's benefit ends at the 21st birthday. Nebraska also requires a discharge plan (a plan for stepping down services), so ask your child's BCBA to plan for that birthday early.
How many hours of ABA therapy does Medicaid cover?
There's no single federal number. CMS notes there's no agreed number of hours for ABA, so your child's BCBA recommends hours a week from the assessment. For children under 21, a state can set a weekly limit, but federal rules require a way to approve more when a child needs it.
Do I need a Medicaid waiver to get ABA therapy?
No, not for a child under 21. Federal guidance says autism services for children belong in regular Medicaid, not a Medicaid waiver. Waivers can add other help, such as respite care (short breaks for caregivers).
Does Medicaid cover autism testing?
Yes, for children under 21. Children's checkups include autism screening, and a child who screens positive should be referred for a diagnosis without delay. Nevada and Nebraska both cover the evaluation that follows. If your child doesn't have a diagnosis yet, Alpaca Health offers an autism evaluation and checks your coverage first.
Can my child get ABA at home or at school with Medicaid?
In-home ABA sessions are covered in both states. Nevada requires a parent, or an adult the parent picks, to be home during training and supervision visits. Since July 1, 2026, Nebraska covers ABA at school only through the school's own Medicaid program. Nevada won't pay for ABA aimed at education.
