ABA Therapy in Colorado: Complete Guide for Parents (2026)

If your child has been diagnosed with autism spectrum disorder (ASD) and you live in Colorado, you are in one of the best states in the country for ABA therapy coverage. Colorado has no annual dollar caps and no age limits on private insurance coverage for autism treatment — a combination that relatively few states have achieved.

This guide covers everything Colorado families need to know: how insurance coverage works, what Medicaid pays for, where to find providers, and what to expect when starting ABA therapy.

ABA Therapy Insurance Coverage in Colorado

Colorado passed autism insurance reform legislation in 2010 and has strengthened it since. Here is what the current law requires for state-regulated health insurance plans:

• No annual dollar caps. Colorado was an early state to eliminate benefit caps entirely. Private insurers cannot put a dollar ceiling on ABA therapy coverage.
• No age limits. The Colorado mandate covers individuals of all ages — there is no cutoff at 18 or 21.
• Medically necessary ABA is covered. Coverage applies when a physician or licensed psychologist determines ABA therapy is medically necessary based on an autism diagnosis.
• Major carriers in Colorado that cover ABA therapy include Anthem Blue Cross Blue Shield of Colorado, UnitedHealthcare, Cigna, Aetna, and Kaiser Permanente.

Important Note on Self-Funded Employer Plans

Colorado's insurance mandate applies to fully insured, state-regulated health plans — including most individual plans, small group plans, and many employer-sponsored plans purchased through the state. However, self-funded employer plans governed by ERISA federal law are typically exempt from state mandates. If your insurance comes through a large employer, check with your HR department or plan administrator to confirm ABA therapy is covered.

Health First Colorado: Medicaid Coverage for ABA

Health First Colorado is Colorado's Medicaid program. It covers ABA therapy for eligible children and young adults under age 21 when services are deemed medically necessary — with no dollar caps under the federal EPSDT (Early and Periodic Screening, Diagnostic, and Treatment) mandate.

Key things to know about ABA through Health First Colorado:

• Your child must have a documented autism spectrum disorder diagnosis
• A physician or licensed psychologist must recommend ABA as medically necessary
• Prior authorization is typically required before starting services
• Services are delivered through Health First Colorado Managed Care Organizations (MCOs) in most parts of the state
• Both in-home and center-based ABA therapy are covered when clinically appropriate

If your household income qualifies, Health First Colorado covers ABA therapy at no cost to the family. You can check eligibility and apply at Colorado PEAK (peak.colorado.gov).

Finding ABA Therapy Providers in Colorado

Colorado has a growing network of ABA therapy providers, concentrated in the Denver metro area and Front Range, with expanding access in smaller communities. Major provider organizations operating in Colorado include:

• Clinics in the Denver and Aurora metro area
• Center-based and in-home providers serving Colorado Springs
• Telehealth ABA services covering rural and mountain communities where in-person providers are limited
• Early intervention specialists serving children ages 2 to 5 through Colorado's Child Find program

Wait times for ABA therapy in Colorado vary significantly by provider and location. In the Denver metro area, wait times of 4 to 12 weeks are common. Families in rural Colorado or mountain communities may face longer waits for in-person services, making telehealth ABA a practical option.

Colorado's Early Intervention System

Children under 3 who show developmental delays or are diagnosed with autism are eligible for Colorado's Early Intervention (EI) program, administered by the Colorado Department of Human Services. Early Intervention services are provided in natural environments (typically the home) at no cost or low cost based on family income.

Children who age out of Early Intervention at 3 may transition to Colorado's Part B special education services through their local school district, or to private ABA therapy covered by insurance or Medicaid.

Early intervention is important because research consistently shows that starting ABA therapy before age 5 — particularly in the 2 to 4 age range — is associated with the most significant gains in communication, adaptive behavior, and daily living skills.

ABA Therapy Costs in Colorado

For families without insurance coverage or with high deductibles, understanding the cost of ABA therapy helps with planning:

• BCBA initial assessment: $300 to $600 per hour (typically 3 to 6 hours of evaluation)
• ABA therapy sessions: $120 to $175 per hour for RBT-delivered therapy (BCBA supervision is included in the overall program cost)
• Center-based full-day programs: $5,000 to $10,000 per month for 30+ hours per week
• In-home part-time programs: $2,000 to $4,000 per month for 15 to 20 hours per week

These costs make insurance coverage essential for most families. With Colorado's strong insurance mandate and Medicaid coverage, the majority of children with autism in Colorado can access ABA therapy at little or no out-of-pocket cost.

What to Look for When Choosing a Colorado ABA Provider

Choosing an ABA provider is one of the most important decisions you will make for your child. Here is what to evaluate:

• BCBA credentials: Confirm your child's supervising clinician is a Board Certified Behavior Analyst. You can verify BCBA credentials at bacb.com.
• BCBA supervision hours: Ask how many direct supervision hours each child receives per month. A higher ratio of BCBA time typically means better quality care.
• Parent training: Quality ABA programs include regular parent training sessions. You should be learning strategies to use between sessions.
• Insurance acceptance: Confirm the provider is in-network with your specific insurance plan. Out-of-network ABA can be significantly more expensive even when you have coverage.
• Staff turnover: Consistency of RBT staffing matters. High turnover disrupts the therapeutic relationship and slows progress.
• Data-based decision making: Ask how the program measures your child's progress and how often the treatment plan is reviewed and updated.

Telehealth ABA in Colorado

For families in rural Colorado — including communities along the Western Slope, San Luis Valley, and mountain regions — telehealth ABA therapy has become an increasingly practical option. Several Colorado-licensed ABA providers offer parent-mediated telehealth services where a BCBA coaches parents and caregivers remotely while they implement strategies with their child at home.

Colorado Medicaid and most private insurers that cover ABA therapy in person also cover telehealth ABA when delivered by a licensed provider. If you are in a rural area or face long waitlists, ask potential providers specifically about telehealth options.
