How to Find ABA Therapy in the Denver Metro Area: A Step-by-Step Guide for New Families

The moment you start looking for ABA therapy for your child, you realize how many steps there actually are — and how few people explain them clearly.

Your pediatrician hands you a referral. Someone mentions Medicaid. A Google search pulls up a dozen provider names. And suddenly a process that's supposed to help your child becomes its own source of stress.

Finding ABA therapy in the Denver metro area involves five core steps — getting a diagnosis, securing insurance coverage, finding a qualified provider who serves your area, completing an intake assessment, and starting therapy. The entire process can take as little as a few weeks when families work with the right provider. 

Step 1: Get the Diagnosis — and Know What You Actually Need

Before ABA therapy can begin in Colorado, your child typically needs a formal autism spectrum disorder (ASD) diagnosis from a licensed professional.

Who can diagnose autism in Colorado:

• Developmental pediatricians
• Licensed child psychologists
• Pediatric neurologists
• Psychiatrists with experience in ASD

The process starts with your child's primary care pediatrician. If they share your concerns about developmental delays or behavior, they'll issue a referral to a specialist. That specialist will use standardized diagnostic tools — including the ADOS (Autism Diagnostic Observation Schedule) and ADI-R (Autism Diagnostic Interview-Revised) — to conduct a formal evaluation.

For children under 3: Colorado's Early Intervention (EI) program provides free developmental screenings and referrals for evaluation — no diagnosis required to access screenings. This is one of the most underused resources for Denver metro families with very young children.

What to bring to your evaluation:

• Developmental records and any previous screenings
• School or daycare observations if available
• Notes on specific behaviors you've noticed, with examples

Once your child has a formal ASD diagnosis and a letter from their doctor confirming that ABA therapy is medically necessary, you're ready for the next step.

Important: Colorado Medicaid (Health First Colorado) covers behavioral therapy for children without an autism diagnosis if services are deemed medically necessary. However, a formal ASD diagnosis is required for most private insurance coverage of ABA specifically. If you're unsure about your situation, contact an ABA provider directly — many, including Inclusive ABA, offer free consultations.

Step 2: Understand Your Insurance Options in Colorado

This is where Denver metro families often hit a wall. Insurance for ABA therapy has layers — but once you understand how Colorado law structures it, the picture gets clearer.



Private Insurance (Fully Insured Plans)

Colorado state law mandates that fully insured private insurance plans must cover ABA therapy for children with an autism diagnosis who are under 19. This applies to plans purchased through an employer (if the employer uses a fully insured plan), through the state Marketplace, or individually.

Insurance accepted in the Denver metro area commonly includes:

• Anthem Blue Cross Blue Shield
• United Healthcare / Optum
• Cigna
• Aetna
• Kaiser Permanente
• Tricare (military families)

One important caveat: Many large employer-sponsored plans are "self-funded" and governed by federal ERISA law rather than Colorado state mandates. These plans may or may not cover ABA. 

Always call the member services number on your insurance card and ask specifically: "Does my plan cover Applied Behavior Analysis (ABA) therapy for a child with an autism diagnosis?".

Health First Colorado (Medicaid)

Health First Colorado is Colorado's Medicaid program and covers ABA therapy for children and youth under 21 through the EPSDT (Early and Periodic Screening, Diagnostic, and Treatment) program — with no annual visit cap for medically necessary services.

To qualify for Health First Colorado, your household income must meet certain income limits based on family size. Colorado also offers a Buy-In Program for Children with Disabilities that allows families earning up to 300% of the Federal Poverty Level (FPL) to purchase Health First Colorado coverage by paying a monthly income-based premium. This lesser-known option helps a significant number of Denver families access services they might otherwise assume are out of reach.

You can apply for Health First Colorado through:

• Colorado PEAK (online — fastest option)
• Your local county human services office
• By phone or mail

If you have both private insurance and Medicaid: In Colorado, Medicaid is considered the payor of last resort. Your private insurer must provide a denial letter stating that ABA is not covered before Medicaid will step in. This is a critical step many families miss.

Step 3: Find a Qualified ABA Provider in the Denver Metro Area

The Denver metro area has many ABA providers — but not all accept every insurance type, not all offer in-home services, and waitlists can vary significantly by provider.

What to look for in a Denver metro ABA provider:

Board Certified Behavior Analysts (BCBAs): All treatment plans should be developed and overseen by a BCBA. Therapy sessions are then delivered by Registered Behavior Technicians (RBTs) under BCBA supervision. Confirm that the provider employs credentialed staff — this is a Colorado state licensing requirement.

Insurance verification: Ask upfront whether the provider is enrolled with your specific insurance plan. Colorado's official Pediatric Behavioral Therapies Provider List (maintained by the Colorado Department of Health Care Policy and Financing) lists licensed providers who accept Health First Colorado (Medicaid) across the Denver metro, including providers in Aurora, Lakewood, Littleton, Arvada, Wheat Ridge, and beyond.

In-home vs. center-based services: Many Denver metro families prefer in-home ABA therapy because it allows children to learn in a familiar environment and enables caregivers to be directly involved. Some providers also offer school-based ABA, meaning a therapist works with your child at their school or daycare with the school's cooperation.

No-waitlist access: Waitlists for ABA therapy in Colorado have historically been a barrier — one source notes that in some cases families wait six months or more for services. When evaluating providers, ask directly: "What is your current wait time for new families?"

Bilingual services: If English is not your family's primary language, ask whether the provider offers bilingual BCBAs or RBTs. Families in Denver, Aurora, and Lakewood with Spanish-speaking households should specifically ask about bilingual availability before committing to a provider.

Step 4: Complete the Intake Process

Once you've selected a provider and confirmed insurance, the intake process begins. Here's what it typically involves:

1. Initial consultation
Most providers offer a free initial consultation — either by phone or in person. This is your chance to ask questions, understand their approach, and determine whether they're the right fit.

2. Insurance verification
The provider verifies your insurance benefits and confirms what's covered before assessment begins. A good provider handles this for you, including prior authorization requests.

3. BCBA assessment (Functional Behavior Assessment)
Before therapy starts, a BCBA conducts a comprehensive assessment to evaluate your child's skills, behaviors, and goals. This typically takes 1–2 weeks once the referral and insurance verification are in place.

4. Prior Authorization Request (PAR)
For Medicaid families, Colorado requires a PAR before ABA therapy begins. The ABA provider prepares this documentation — including the assessment results, your child's diagnosis, and a proposed treatment plan — and submits it to the state's utilization vendor for review. Approvals typically cover up to six months, after which the provider submits for renewal.

5. Therapy begins
Once the treatment plan is approved, your child is matched with an RBT and therapy sessions are scheduled. Many families in the Denver metro can begin services within a few weeks of completing intake.

Step 5: Stay Actively Involved — Especially at the Start

ABA therapy is most effective when families are active participants. Colorado Medicaid specifically includes parent and caregiver training as a covered service under ABA — meaning your provider can deliver structured training to help you reinforce ABA strategies at home.

Key ways to stay engaged:

• Attend BCBA-led parent training sessions
• Review data summaries from each therapy session
• Communicate directly with your BCBA about what you're seeing at home
• Participate in goal-setting reviews (typically every 6 months)

If you've been placed on a waitlist elsewhere, use the waiting time productively. Some providers offer parent-mediated coaching or parent training sessions while formal therapy authorization is pending. Bringing IEP documents, previous evaluations, and therapist notes to your first meetings can also speed the authorization process.
