The 4-Step Path to Starting Care

Most families spend weeks figuring out a process that takes about four steps once you know them.

Step 1: Get a referral. Your child's pediatrician is the one who writes a referral for ABA therapy. You need a formal autism diagnosis and this referral before any provider can begin the intake process. If you don't have a diagnosis yet, Alpaca offers free ADOS-2 evaluations for children ages 18 months to 6 years.

Step 2: Verify your insurance. Call the member services number on your insurance card and ask whether ABA therapy is covered for your child's diagnosis, what your deductible balance is, and whether prior authorization is required. Alpaca handles this step for you once you submit your intake.

Step 3: Complete an intake. Each provider has their own intake process. Alpaca's takes minutes online and results in a match within 24 hours. Traditional clinic intakes can take up to two to four weeks before you hear back.

Step 4: Schedule the initial assessment. Before therapy begins, a BCBA conducts a skills assessment and builds your child's individualized treatment plan. At Alpaca, this happens in the same week as intake.

Skip the Waitlist

Denver families who work with independent BCBAs through platforms like Alpaca typically find availability much faster than through traditional clinic intake processes. Independent BCBAs working through platforms like Alpaca carry smaller caseloads and open slots faster. Skipping the waitlist in Denver is possible for families who know where to look.

How Much Does ABA Therapy Cost in Denver?

Health First Colorado: $0

If your child is enrolled in Health First Colorado (Colorado Medicaid), ABA therapy is covered at no cost to the family for children under 21. This is a federal EPSDT requirement, not a discretionary benefit. You need a diagnosis, a physician's referral, and an in-network provider. Alpaca is in-network with Health First Colorado. The state's Medicaid coverage for ABA follows the federal EPSDT rule for children under 21. If you're not yet enrolled, Health First Colorado enrollment starts at the state PEAK portal.

Commercial Insurance in Denver

Colorado law requires most fully-insured health plans to cover ABA therapy for autistic children. Alpaca is in-network with Aetna, Anthem Blue Cross Blue Shield, Cigna, Tricare, and more than 100 other players. Your out-of-pocket cost depends on your deductible, coinsurance rate, and out-of-pocket maximum. Many families on standard commercial plans hit their out-of-pocket maximum within the first few months of a full therapy schedule, after which the rest of the year costs them nothing.

Out-of-Pocket and Financial Assistance

Without insurance, ABA in Denver runs $120 to $150 per hour for BCBA-direct sessions and $70 to $100 per hour for RBT-delivered sessions. At 20 hours per week, that's $1,400 to $3,000 per week before coverage. Families without insurance or with high-deductible plans can compare national ABA cost ranges and look into Colorado autism funding options including the HCBS waiver and other financial assistance programs.

In-Home vs. Clinic vs. Virtual vs. In-School ABA in Denver

In-Home ABA

In-home ABA brings the BCBA or RBT to your child's environment. Skills learned at home can generalize more readily because they're practiced where they actually matter: at the breakfast table, during bath time, in the backyard. In-home is often the strongest choice for toddlers and younger children who aren't yet in school and for families with transportation barriers. Knowing what in-home sessions look like helps parents prepare their space.

In-Clinic ABA

Clinic-based ABA happens in a structured therapy environment with more controlled materials and consistent routines. It's well-suited for children who benefit from a dedicated therapy space away from home distractions, and for intensive programs where a child is working on multiple goals simultaneously. The tradeoff is that clinic ABA requires reliable transportation and usually carries longer waitlists in Denver than other delivery modes.

Virtual ABA

Virtual ABA, also called telehealth ABA, is a parent-coached model in which the BCBA guides you through therapy techniques in real time over video. You are the hands-on therapist in the room; the BCBA directs and coaches from the screen. It's the fastest path to starting care in Denver because there's no geographic matching required. Virtual ABA therapy through Alpaca can start in days regardless of where in the Denver metro you live.

Virtual ABA is not a lesser version of in-person therapy. For parent training goals, generalization of skills, and families in lower-provider-density parts of the metro, it's often the most effective option.

In-School and Community ABA

In-school ABA embeds therapy into your child's school day, working directly on IEP goals in the environment where those skills are needed. Community-based ABA practices skills in real-world settings: grocery stores, playgrounds, restaurants. Both modes are available through Alpaca and are often combined with home or clinic sessions as part of a broader treatment plan.

How to Choose the Right ABA Provider in Denver

BCBA Credentials and Supervision Ratios

Every ABA treatment plan must be designed and supervised by a Board Certified Behavior Analyst. Ask any provider: What is the BCBA-to-child ratio on your caseload? How many direct hours per month will my child receive from the BCBA versus the RBT? How often will the BCBA observe sessions directly?

Parent Training

Parent training is important in effective ABA. It’s helpful if the skills your child learns in sessions carry into mealtimes, bedtime routines, and transitions at home. Ask providers how parent training is structured, how often it happens, and whether it's built into the treatment plan or an add-on you pay for separately. Alpaca includes twice-monthly Family Guidance sessions in every treatment plan.

Red Flags

Leave a provider consultation if you hear any of the following: a focus on eliminating behaviors without replacing them with functional alternatives, rigid protocols that don't account for your child's sensory profile or communication needs, pressure to commit to a specific hour count before the initial assessment is complete, or vague answers about how the BCBA will be involved in your child's sessions. A provider who talks about making your child "indistinguishable from peers" is telling you something important about their philosophy.

What age range does ABA therapy serve in Denver?

ABA therapy through Alpaca serves children and young adults ages 0 to 21. Free ADOS-2 diagnostic evaluations are available for children ages 18 months to 6 years. The approach and goals shift by age: toddler programs focus on early communication and play, school-age programs integrate with IEP goals, and teen and young adult programs focus on self-advocacy and transition planning.

How many hours per week does my child need?

The recommended hours depend on your child's age, diagnosis, and goals. Toddlers in early intervention programs often receive 15 to 25 hours per week. School-age children typically receive 10 to 20 hours. Your child's BCBA will recommend a specific hour count after the initial skills assessment. That recommendation, not a number you read online, is what your child's plan should be built around.

Is in-home or clinic ABA better for toddlers in Denver?

For most toddlers, in-home ABA produces stronger skill generalization because therapy happens where skills are actually used. Denver clinic-based programs offer structured environments that work well for some children, but for children under 4 who are learning communication, daily living, and play skills, practicing those skills at home with caregivers present is typically more effective. Ask your BCBA which setting fits your child's specific profile.
