North Carolina Medicaid does cover ABA therapy, for both children and adults diagnosed with autism spectrum disorder, as long as the treatment is medically necessary. There are no copays. The benefit sits inside a service category called Research-Based Behavioral Health Treatment, governed by Clinical Coverage Policy 8F, and it requires a formal diagnosis, a signed service order, and prior authorization from your health plan before therapy can begin.
Coverage for children under 21 runs through the federal Early and Periodic Screening, Diagnostic, and Treatment mandate, which obligates Medicaid to pay for medically necessary services to treat or improve a diagnosed condition. Adults 21 and older gained coverage effective July 1, 2021, after the Centers for Medicare and Medicaid Services approved North Carolina’s request to extend the benefit.
Who Qualifies
Any NC Medicaid beneficiary with an autism spectrum disorder diagnosis can receive ABA therapy if a qualified provider documents medical necessity. How that works depends on age and program.
For children under 21, EPSDT is the key. Because federal law requires Medicaid to cover any medically necessary service for beneficiaries under 21, the service limits written into Clinical Coverage Policy 8F can be exceeded when the provider documents the child needs more. In practice, that means there is no hard cap on weekly hours for a child whose treatment plan supports intensive therapy, though as of 2026 there are new review requirements above 16 hours per week (see below).
For adults 21 and older, the intervention still has to be supported by credible scientific or clinical evidence appropriate for the person’s age. Adult requests go through the beneficiary’s LME-MCO or Standard Health Plan.
NC Health Choice, the state’s CHIP program for children ages 6 through 18, also covers ABA therapy. As of April 1, 2023, NCHC recipients are covered under the EPSDT benefit as well, so the same “medically necessary” standard applies.
To be eligible for NC Medicaid in the first place, children under 19 can qualify in families earning up to 216 percent of the federal poverty guidelines. Adults 19 and older can qualify with income up to 138 percent of the federal poverty guidelines following the state’s Medicaid expansion, which took effect December 1, 2023. You can apply through NC ePASS, HealthCare.gov, or at a local Department of Social Services office.
The Diagnosis You Need Before Therapy Starts
Before ABA can be authorized, the beneficiary needs a confirmed autism spectrum disorder diagnosis made with a scientifically validated diagnostic tool. NC Medicaid recognizes four:
- the Autism Diagnostic Interview-Revised
- the Autism Diagnostic Observation Schedule, second edition
- the Childhood Autism Rating Scale, second edition, standard version
- the TELE-ASD-PEDS, for children 36 months or younger when barriers prevent an in-person evaluation
Common screening instruments like the Modified Checklist for Autism in Toddlers or the Gilliam Autism Rating Scale are not accepted as standalone diagnostic tools.
Children under three can start therapy on a provisional diagnosis, which a licensed psychologist, physician, or master’s-level clinician can make when there is significant concern for ASD based on screening, parent report, or observed symptoms. A formal ASD diagnosis has to be confirmed within six months.
A licensed physician (MD or DO) or a licensed psychologist then has to sign and date a service order before treatment begins. The order must rest on a behavioral, adaptive, or functional assessment, and it is valid for one year. After that, medical necessity has to be reassessed and the order renewed.
Getting Prior Authorization
Every ABA service requires prior authorization from the beneficiary’s Prepaid Health Plan, Tailored Plan, or LME-MCO before treatment starts. Services delivered without it will be denied for payment, so this step is not optional.
A Licensed Qualified Autism Service Provider writes the individualized treatment plan, which has to include measurable goals and specific timelines. The provider then submits a Treatment Authorization Request with the clinical documentation showing medical necessity. For EPSDT-eligible children, the provider also uploads the EPSDT non-covered services request form. The health plan has 14 days from receipt to approve or deny.
A few practical points that trip families up. Requests cannot be submitted more than 30 days in advance, and they cannot be backdated. For renewals, an updated treatment plan is required, and reauthorization will be denied if the annual plan rewrite has not been completed or if elements like the crisis prevention plan or goals are missing. Treatment plans have to be reviewed at least every six months by the Licensed Qualified Autism Service Provider and fully rewritten at least once a year.
What Families Pay
Nothing. NC Medicaid charges no copays for behavioral health services, and ABA therapy sits in that category. The exemption applies regardless of age. Separately, all Medicaid beneficiaries under 21 are exempt from copays for any service. NC Medicaid does charge up to $4 for some other services like doctor visits and prescriptions, but ABA therapy carries zero out-of-pocket cost.
If Your Request Gets Denied
If a health plan or LME-MCO denies a request, you have appeal rights, and the standard on appeal is whether the service is medically necessary to prevent, diagnose, or treat the condition.
The first step is reconsideration. Within 60 days of the denial notice, submit a Reconsideration Request Form to the LME-MCO. The organization must respond within 30 days. In urgent situations you can request expedited reconsideration, with a response required within three days.
If reconsideration upholds the denial, you have 120 days to file for a state fair hearing with the Office of Administrative Hearings. The hearing request form has to be filed with both the LME-MCO and the OAH. You will also be offered voluntary mediation. Disability Rights NC recommends taking part, because it can surface the plan’s reasoning and sometimes resolves the dispute without a hearing.
You are entitled to your entire case file at no charge, and you can bring new evidence to the hearing, including letters from doctors, medical records, and caregiver testimony.

New Rules Taking Effect in 2026
North Carolina is tightening its ABA program, and several changes affect how coverage will work going forward. On April 30, 2026, Governor Josh Stein signed House Bill 696, which gave DHHS and managed care organizations new oversight tools. The main changes families will feel:
- Paraprofessional services generally cannot be delivered via telehealth, and all assessments by a Licensed Qualified Autism Service Provider must be done in person.
- Board-certified behavior analysts and qualified autism service practitioner supervisors are barred from enrolling as out-of-state providers.
- Any service plan exceeding 16 hours per week requires health plan or department approval, with monthly reapproval.
- Behavior technicians must hold national RBT or ABAT certification after a 120-day grace period.
- Health plans must review authorizations monthly.
DHHS released draft updates to Clinical Coverage Policy 8F on May 15, 2026, and ran a public comment period through June 14, 2026. Phase one of the reforms is targeted for implementation by August 1, 2026. A second phase, expected in December 2026, would prohibit providers from both diagnosing autism and referring patients to their own ABA services.
One earlier change worth flagging: on October 1, 2025, NCDHHS implemented a 10 percent cut to ABA reimbursement rates. A Wake County Superior Court judge issued an injunction on November 10, 2025 temporarily halting the ABA-specific cut after parents of children with autism sued.
A Note on Private Insurance
If you also carry private insurance, coverage there works differently. North Carolina has a separate autism insurance mandate under Senate Bill 676, enacted in 2015 and effective July 1, 2016, which requires certain state-regulated health plans to cover ABA therapy. That mandate applies to individual grandfathered plans, fully insured large group plans, and fully insured small group grandfathered plans. It does not apply to non-grandfathered individual or small group plans. Under the mandate, adaptive behavior treatment coverage can be limited to individuals under 19 and capped at $40,000 per year, indexed to inflation. Medicaid coverage has no such age cap or dollar cap, which is why families whose private plan hits its limit often turn to Medicaid as a secondary or primary payer where they qualify.
