Colorado Medicaid Coverage for ABA Therapy
Health First Colorado covers ABA therapy for eligible children with autism spectrum disorder under the federal EPSDT mandate. Here is what Colorado Medicaid families need to know:
- Health First Colorado covers ABA for children with a formal ASD diagnosis from a qualified provider
- Coverage falls under the EPSDT benefit, which requires Medicaid to cover medically necessary services for children under 21
- Prior authorization is required before ABA services can begin
- A comprehensive treatment plan developed by a licensed BCBA must accompany the authorization request
- Behavioral health services, including ABA, are managed through Colorado's Regional Accountable Entities (RAEs) rather than directly through the state
- There is no hard cap on the number of ABA hours — coverage is based on medical necessity as determined by the BCBA's assessment and approved by the RAE
Understanding Health First Colorado's Behavioral Health System
Colorado's Medicaid behavioral health system is unique. Instead of a single statewide managed care plan, Colorado uses seven Regional Accountable Entities (RAEs) to manage behavioral health benefits across different parts of the state. This has a direct impact on how families access ABA therapy:
Seven RAEs Manage Behavioral Health Across Colorado
Colorado is divided into seven RAE regions, each operated by a different managed care organization. Colorado Access, Northeast Health Partners, Health Colorado, and others each manage behavioral health services — including ABA — for their assigned counties. Your child's RAE is determined by the county where you live, and each RAE maintains its own network of credentialed ABA providers.
Each RAE Has Its Own ABA Provider Network
An ABA provider who is credentialed with one RAE may not be credentialed with another. Before pursuing a specific provider, you need to confirm that they participate in your RAE's network — not just that they accept "Health First Colorado" in general. Match Care ABA verifies RAE network participation before connecting families with providers, so you never waste time on providers outside your region's network.
Check Your Health First Colorado Member Portal
Your RAE assignment is based on your county of residence. You can find your RAE by logging into the Health First Colorado member portal, calling Health First Colorado member services at 1-800-221-3943, or checking your enrollment documents. Knowing your RAE before searching for ABA providers will save significant time and frustration.
Colorado Medicaid and the CDD Waiver
Children with significant autism-related needs may qualify for additional Medicaid support beyond standard Health First Colorado coverage. Colorado's Children with Life Limiting Illness (CLLI) waiver, the Children's Extensive Support (CES) waiver, and the Children with Disabilities (CDD) buy-in program provide additional services for families whose children have substantial support needs. The CES waiver specifically serves children with developmental disabilities, including autism, and can provide respite care, habilitation services, and other supports that complement ABA therapy. Families should ask their case manager or contact the Community Centered Board (CCB) in their area to determine eligibility for these additional programs.
Even without a waiver, Health First Colorado's EPSDT benefit ensures that medically necessary ABA therapy is covered for children with ASD. The waivers provide supplemental services — they are not required to access ABA coverage through standard Medicaid.
Finding CO Medicaid ABA Providers in Your Area
Finding an ABA provider who accepts Health First Colorado and has current availability involves several real challenges specific to Colorado:
- Provider networks vary by RAE region — a provider credentialed in the Denver metro RAE may not serve families in a mountain or Western Slope RAE
- The Denver metro area (including Aurora, Lakewood, and surrounding suburbs) has the highest concentration of Medicaid-accepting ABA providers in the state
- Colorado Springs and Fort Collins have growing but still limited ABA options for Medicaid families
- Rural and mountain communities — including the Western Slope, San Luis Valley, and Eastern Plains — face significant provider gaps, with some counties having zero local ABA providers
- RAE provider directories do not indicate which providers have current openings or how long their waitlists are
- Some ABA providers accept Health First Colorado for existing clients but are not currently taking new Medicaid referrals
Match Care ABA identifies which ABA providers currently accept Health First Colorado through your specific RAE and have openings for new clients — including home-based providers who can serve families in rural and underserved communities across the state.

RAE-Confirmed Matching
Before connecting you with a provider, we confirm that they are credentialed within your specific RAE's network and are genuinely accepting new Health First Colorado clients. This eliminates weeks of phone calls and intake paperwork only to discover the provider is not in your RAE or has a closed caseload.

We serve Health First Colorado families across all 64 Colorado counties and all seven RAE regions. We specifically work to identify options for families in rural and mountain communities where Medicaid-accepting ABA providers are hardest to find — including home-based and telehealth ABA services that can reach underserved areas.
