Key Highlights

• Yes, Virginia Medicaid requires service authorization for ABA treatment, though the initial assessment does not need one.
• ABA is covered for members under 21 through EPSDT when it is medically necessary and supported by an autism diagnosis.
• Requests go to Acentra Health for fee-for-service members or to your Cardinal Care health plan for managed care members.
• Authorization requests must list units for each ABA billing code, not one lump sum.
• A 20-hour weekly limit is being phased in, and more hours need documented medical necessity.
• Complete documentation, early renewals, and knowing your appeal rights help prevent gaps in care.

If your child has Virginia Medicaid and has just received an autism diagnosis, you may be wondering how soon ABA therapy can begin and whether anyone has to approve it first. The short answer is yes, there is an approval step. What surprises many families is how many moving parts sit behind it: a diagnosis, an assessment, a treatment plan, and a request that goes to the right reviewer.

Virginia has also been updating its ABA rules. The state clarified requirements in late 2025 and has announced new limits tied to the 2026 budget. Knowing how the process works helps you ask better questions, spot problems early, and avoid gaps in your child’s services.

This guide explains whether Virginia Medicaid requires prior authorization for ABA therapy, who reviews the request, what has to be in it, and what to do if you get a denial.

The Short Answer: Yes, ABA Treatment Needs Prior Authorization

Virginia Medicaid requires service authorization before ABA treatment services are delivered. Under a DMAS bulletin on ABA service authorization that applies to dates of service on or after October 15, 2025, providers must request units for each treatment billing code they plan to use, such as direct therapy, supervision, and family guidance. The ABA assessment codes are the exception and do not require authorization.

This matters because services delivered outside an approved authorization are not reimbursable. In practice, that is why a good provider will not start treatment until the approval is in place, and why delays at the authorization stage can delay your child’s first session.

Think of service authorization as the checkpoint between a recommendation and payment. Your child’s clinician recommends a level of care, and the reviewer, either Acentra Health or your health plan, confirms that it meets Virginia’s medical necessity standard. Approval is given for a defined period, which is why renewal timing becomes so important later in the process.

One more note: behavior therapy delivered by local education agency providers through the school-based services program follows separate rules and is not covered by the ABA changes described in this guide.

How Virginia Medicaid Covers ABA and Who Is Eligible

Virginia covers ABA for children and young adults under 21 through EPSDT, the Medicaid benefit that requires coverage of medically necessary services to correct or ease conditions found through screening. Covered ABA services include assessment, treatment, and family training, delivered by licensed professionals or by technicians working under their supervision.

To qualify, a child generally needs three things:

• A diagnosis of autism spectrum disorder from a licensed professional
• Documentation that ABA is medically necessary for the child’s needs
• An approved service authorization before treatment begins

The 2026 state budget directs the Department of Medical Assistance Services (DMAS) to require an autism diagnosis before ABA is authorized, with a one-year provisional diagnosis available for children 5 and younger under a protocol DMAS designates. The same budget language sets a 20-hour-per-week cumulative limit per child, which can be exceeded when medical necessity is documented under EPSDT. DMAS has said these changes depend on federal approval, and its latest ABA bulletin states that the current authorization process stays in place until that happens.

Who Approves the Request: Fee-for-Service or Your Health Plan

Who reviews your child’s request depends on how your child receives Medicaid.

• Fee-for-service members. DMAS contracts with Acentra Health to handle behavioral health service authorizations. Your provider submits the request through Acentra’s online system.
• Cardinal Care managed care members. Many Virginia Medicaid children are enrolled in a managed care plan, and that plan reviews the ABA request. The plans listed by DMAS include Aetna Better Health, Anthem HealthKeepers Plus, Humana Healthy Horizons, Sentara Community Plan, and UnitedHealthcare. Providers must follow their contract with the plan, and a plan’s guidelines may differ from fee-for-service rules.

The easiest way to know which applies to you is to check your child’s Medicaid card or ask your provider’s intake team. If you change plans, tell your provider right away, because a change in plan may mean a new authorization request.

Either way, the provider submits the paperwork, but you play an important role by keeping your contact information current, responding quickly to calls, and sharing documents the team asks for.

What the Authorization Request Must Include

A complete request tells a clear story about why your child needs ABA and exactly what the plan will be. Based on DMAS’s ABA policy clarifications, reviewers look for:

• A completed initial assessment done in person by a licensed behavior analyst, assistant behavior analyst, or another qualified licensed professional, with your child and family present
• A functional assessment using validated tools, updated at least once a year
• An individual service plan with measurable goals and a clear treatment schedule
• Units requested for each ABA billing code, such as direct therapy, supervision, and family guidance
• A clinical reason for center-based services, if therapy will not take place at home
• A schedule of telehealth and in-person sessions with clinical support, if telehealth is planned
• Documented weekly family involvement and family training
• For continued authorization, a progress summary that shows how skills are generalizing across settings

If a request would exceed 20 hours a week, DMAS expects detailed justification, including an individualized schedule that separates therapeutic time from non-therapeutic time. Generic clinic schedules are not enough.

Incomplete, outdated, or missing assessments can make services non-reimbursable, so these pieces are worth getting right the first time.

The Authorization Process Step by Step

Step	What happens	Is authorization needed?
Diagnosis	A licensed professional diagnoses autism spectrum disorder	No
Initial assessment	A qualified licensed professional assesses your child in person with your family present	No
Individual service plan	The clinical team sets goals, settings, schedule, and family training	Part of the request
Treatment request	The provider submits units for each ABA billing code to Acentra Health or your health plan	Yes
Review and decision	The reviewer decides whether the request is medically necessary	Decision issued
Continued authorization	The team submits a progress summary and updated assessment before the approval ends	Yes

Each step builds on the one before it. A strong diagnostic report supports the assessment, the assessment shapes the service plan, and the service plan drives the units requested. A gap in any one link can slow the whole chain, which is why teams that gather documents early tend to see fewer surprises.

What We’ve Seen: A Real Example From Practice

In our sessions with Virginia families, we have seen how often delays come from paperwork rather than from a child’s needs. One family’s request for a school-age child was held up when the reviewer asked for more detail. The clinical team had recommended more than 20 hours a week, and the first submission used a general weekly schedule that did not separate therapy time from other activities.

The BCBA rebuilt the request with an individualized schedule showing which blocks were therapeutic and why, updated the assessment, and added a progress summary that showed how skills were carrying over to home and community settings. The family also confirmed which health plan reviewed the request so the right contact received the follow-up. The request was approved, and the team submitted the next renewal well before the approval ended. (Details have been changed to protect the family’s privacy.)

The lesson is that a request built around your child’s individual needs moves more smoothly than a generic one.

How to Avoid Delays and Gaps in Services

1. Confirm which reviewer handles your child’s Medicaid, either Acentra Health or a specific Cardinal Care plan, before you choose a provider.
2. Choose a provider enrolled with Virginia Medicaid and, if you are in managed care, in your plan’s network.
3. Keep your child’s diagnostic report in a safe place and give your provider a copy as early as possible.
4. Attend the in-person assessment, and bring questions about your child’s strengths, routines, and priorities.
5. Review the individual service plan, and make sure it reflects the goals that matter most to your family.
6. Take part in family training sessions each week, because family involvement is a documented requirement, not an optional extra.
7. Ask your provider when the current authorization ends, and ask them to submit the renewal early with a progress summary.
8. Tell your provider right away if your address, phone number, or health plan changes.

If you are waiting on an approval, ask the provider for a realistic timeline and whether anything is missing. A short, specific question often resolves a stalled request faster than waiting.

What to Do If a Request Is Denied or Reduced

A denial or reduction is not the final word. Here is how families can respond:

• Ask for the decision in writing and read the reason carefully, since many denials come from missing or outdated documents.
• Ask your provider whether they can submit additional documentation, such as an updated assessment or a more detailed schedule.
• If your child is in managed care, use the plan’s own appeal process first, and follow the instructions and deadlines in the notice you receive.
• Remember that you have the right to appeal an action that denies, reduces, or terminates Medicaid coverage. The DMAS Appeals Division can be reached at (804) 371-8488.
• When a request is for more than the standard weekly limit, ask your team to document medical necessity under EPSDT, which is the pathway the state has said allows hours above the limit.

Appeals have deadlines, so act quickly and keep copies of every letter, authorization, and message.

Frequently Asked Questions

1. Does Virginia Medicaid require prior authorization for ABA therapy?

Yes. ABA treatment services require service authorization before they are delivered, and the request lists units for each treatment billing code. The ABA assessment codes do not require authorization.

2. Who reviews ABA authorization requests in Virginia?

Fee-for-service requests go to Acentra Health. Requests for children in Cardinal Care managed care go to the child’s health plan, which may use its own guidelines. Your provider can tell you which applies.

3. Is there a weekly hour limit for ABA under Virginia Medicaid?

The 2026 state budget directs DMAS to set a 20-hour-per-week cumulative limit, which can be exceeded with documented medical necessity under EPSDT. DMAS has said the change depends on federal approval and that the current process continues until then, so ask your provider for the latest status.

4. What happens if my child’s authorization expires?

Services delivered outside an approved authorization are not reimbursable, so a lapse can interrupt therapy. Ask your provider to submit the continued authorization request early, with a progress summary and an updated assessment.

5. Does the ABA policy apply to school-based behavior therapy?

No. Behavior therapy delivered by local education agency providers through the school-based services program follows separate rules and is not subject to the ABA changes described in the DMAS bulletin.
