I want to say something gently before we get into the numbers: if you’re worried about the cost of ABA therapy, that doesn’t make you a less-committed parent. It makes you a thoughtful one. Every Colorado family I work with at Achieve ABA Therapy Group has had to think carefully about how to make this work, and the families who ask the cost question early are almost always the ones who set their child up best in the long run.
So let’s go through it together. The sections below cover what ABA therapy typically costs in Colorado, how insurance and Health First Colorado change the picture, which financial assistance programs are worth applying for, and how to land on a real, honest estimate for your family.
What ABA Therapy Costs in Colorado at a Glance
Before we get into insurance, waivers, and provider differences, it helps to know the baseline. The numbers below reflect what private-pay families in Colorado are seeing in 2026 and what most providers in the state list as their standard rates. These figures change once insurance enters the picture, but they’re the right starting point for understanding what your provider is actually billing.
The Standard Hourly Rate Range
For ABA therapy in Colorado, you can expect to see hourly rates in the following ranges:
- Registered Behavior Technicians (RBTs), who deliver most direct therapy: $50 to $80 per hour
- Board Certified Behavior Analysts (BCBAs), who oversee treatment and conduct assessments: $120 to $250 per hour
- Blended/program rates (most common on insurance billing): $120 to $150 per hour
Most insurance claims are billed using CPT codes that combine RBT time and BCBA supervision, so the “hourly rate” you see on a statement usually sits in the $120 to $150 range. When families pay privately, the same range generally applies.
Weekly and Monthly Costs for Common Therapy Loads
Most children in ABA receive between 10 and 40 hours per week, depending on their age and goals. At a $130/hour blended rate, here’s what those loads look like before any insurance is applied:
- 10 hours/week (focused care): ~$1,300/week, or ~$5,600/month
- 20 hours/week (moderate intensity): ~$2,600/week, or ~$11,300/month
- 30 hours/week (comprehensive): ~$3,900/week, or ~$16,900/month
- 40 hours/week (intensive early intervention): ~$5,200/week, or ~$22,500/month
These numbers can land hard the first time you see them written out. The good news is that very few Colorado families pay these amounts out of pocket, because of state insurance laws and Medicaid coverage discussed further down.
Annual Cost Without Insurance
For a child receiving 20 to 30 hours of ABA per week at the typical Colorado rate, the unsubsidized annual cost lands somewhere between $135,000 and $200,000. Children receiving lower intensity (10 hours) may see annual figures closer to $62,000, while intensive 40-hour programs can run upwards of $250,000 a year.
I include these numbers because some families need to see the full picture to understand why insurance verification and Medicaid enrollment are worth pursuing aggressively. They’re rarely the bottom line.
What Goes Into the Bill
A single line item that says “ABA therapy” hides a lot of moving parts. Understanding the components helps when you’re reading a statement, comparing providers, or trying to figure out why one provider’s quote looks different from another’s.
Direct Therapy Hours (RBT Time)
The bulk of any ABA program is direct one-on-one therapy with a Registered Behavior Technician. This is where the actual skill-building happens—play-based learning, communication work, daily living routines, social engagement. RBT hours are typically billed under CPT code 97153 and represent the largest single line item on most invoices.
BCBA Supervision and Treatment Planning
A BCBA designs the treatment plan, supervises the RBT, modifies goals as your child progresses, and meets with you to review data. This time is billed under different codes (97155 for direct supervision, 97156 for parent training, 97151 for assessment work). BCBA hours are fewer in number than RBT hours but billed at a higher rate. Both pieces are required for an ethical, effective program.
Assessments and Re-Evaluations
Every program begins with a comprehensive assessment that typically runs 6 to 8 BCBA hours across multiple appointments. Most insurance plans require a re-assessment every six months. These appointments are billed separately from ongoing therapy and usually run $700 to $1,500 per assessment cycle.
Parent Training Sessions
This is one of the most overlooked pieces of ABA billing, and one of the most valuable parts of the program. Parent training sessions, where the BCBA coaches you on the same strategies being used in therapy, are typically billed under code 97156. Many insurance plans cover these sessions in full, and skipping them is one of the bigger mistakes I see families make.
How Insurance Changes the Cost in Colorado
Colorado is one of the better states in the country for ABA insurance coverage, and most families who walk in expecting to pay sticker price end up paying a fraction of it. The sections below cover the three insurance pathways most Colorado families use.
Colorado’s Autism Insurance Mandate
Colorado has had a state autism insurance mandate in place since July 2010, and it has been expanded several times since. The mandate requires most state-regulated private insurance plans to cover medically necessary ABA therapy for individuals with an autism diagnosis. This includes assessments, ongoing therapy sessions, BCBA supervision, and parent training.
What you’ll typically still owe with private insurance: your standard deductible, copays per session, and any coinsurance percentage your plan applies. Out-of-pocket costs vary widely but generally fall between $0 and $8,000 per year for families with employer or marketplace plans.
Health First Colorado (Medicaid) Coverage
Health First Colorado, the state’s Medicaid program, covers ABA therapy for children and teens under 21 through the EPSDT (Early and Periodic Screening, Diagnostic, and Treatment) benefit. Coverage is determined by medical necessity, requires prior authorization, and—when approved—comes with no visit limits.
For families on Medicaid, out-of-pocket cost for ABA is typically zero. If your child has both private insurance and Medicaid, the private plan is billed first, and Medicaid covers any remaining medically necessary costs. Medicaid is what’s called the “payor of last resort” in Colorado.
If you’re not sure whether you qualify, it’s worth applying. Eligibility depends on income and household size, but Colorado has expanded thresholds for children with disabilities, and some families qualify even when they wouldn’t for general Medicaid.
Self-Funded Employer Plans and ERISA
There’s one important asterisk to Colorado’s insurance mandate. Plans that are “self-funded” by large employers fall under federal ERISA law rather than Colorado state law, which means they aren’t required to follow the state mandate. Many self-funded employers cover ABA anyway, but coverage details vary plan by plan.
If you have a self-funded plan (your HR department can confirm), call your insurer directly before scheduling services and ask specifically about ABA coverage, prior authorization requirements, and any annual limits. We help families do this verification at Achieve ABA Therapy Group before they enroll, so there are no surprises.
Other Financial Assistance Options for Colorado Families
Beyond standard insurance, Colorado has a handful of programs specifically designed to reduce or eliminate ABA costs for families with significant needs. These options are underutilized, partly because the application processes aren’t well advertised.
The Children’s Extensive Support (CES) Waiver
The CES Waiver is a Medicaid waiver program for children under 18 with significant developmental disabilities, including autism with substantial support needs. It can cover ABA hours beyond what standard Medicaid provides, plus respite care, home modifications, and other family supports.
CES eligibility is based on the child’s level of need rather than household income, which means many middle-income families qualify even if they don’t qualify for regular Medicaid. There’s typically a waitlist, so applying early is worth it.
Child Health Plan Plus (CHP+)
CHP+ is Colorado’s low-cost insurance program for families who earn too much for Medicaid but still need help affording coverage. It covers ABA therapy for eligible children with autism, with copays usually in the $5 to $20 range per visit and annual out-of-pocket maximums significantly lower than commercial plans.
Sliding-Scale and Scholarship Options
Some Colorado providers offer sliding-scale fees, payment plans, or limited scholarship slots for families who don’t qualify for Medicaid but can’t manage the full private-pay rate. These options aren’t always advertised; you usually have to ask. When you’re comparing providers, raise the financial question early. A provider who’s transparent about fees and willing to work with you is generally a provider who’ll be transparent about your child’s progress too.
What Drives the Cost Up or Down
Once insurance is in the picture, the remaining cost variation comes from a handful of factors specific to your child’s program. Understanding these helps you make sense of quotes from different providers.
Therapy Intensity (Hours Per Week)
Hours per week is the single biggest cost driver. A child receiving 10 focused hours will have a dramatically smaller bill than one receiving 35 comprehensive hours, even at identical rates. Intensity should be set by your BCBA based on a clinical assessment, not by what you can afford—but it’s a fair question to ask about during your initial consultation.
In-Home vs. Center-Based Sessions
Hourly rates for in-home and center-based ABA are typically similar in Colorado, but center-based programs sometimes carry small additional fees that cover materials and facility overhead. In-home sessions may include mileage reimbursement billed to insurance. The bigger consideration is usually fit—some children make faster progress in a center, others at home. Cost differences are minor by comparison.
Provider Experience and Credentials
A BCBA with 15 years of experience and specialty training in early intervention will charge more than a newly certified BCBA, and that difference shows up in the supervision portion of your bill. For most families, an experienced clinical director overseeing a strong RBT team produces the best balance of cost and outcomes.
How to Get a Real Estimate for Your Family
The most useful thing you can do before committing to a provider is to get a written estimate that includes your specific insurance details, your child’s recommended hours, and the provider’s actual contracted rates with your plan. The sections below cover how to do that.
Questions to Ask Any Provider Before You Commit
When you’re calling around to providers, ask:
- Are you in-network with my insurance?
- What’s your typical out-of-pocket cost for a family with my plan?
- How many hours are you recommending and why?
- What does the assessment cost, and is it billed separately?
- Do you handle prior authorization, or do I need to?
- What happens if my insurance denies coverage mid-treatment?
A provider who can answer these clearly and in writing is a provider worth working with.
What to Verify with Your Insurance Company
Call the member services number on your insurance card and ask:
- Is ABA therapy a covered benefit on my plan?
- What’s my deductible and how much have I met this year?
- What’s my copay or coinsurance per ABA session?
- What’s my annual out-of-pocket maximum?
- Do I need prior authorization, and what does the approval process look like?
- Are there any annual visit or dollar limits?
Get the representative’s name and a reference number for the call. Insurance information shifts, and a documented call protects you later.
At Achieve ABA Therapy Group, we run a benefits verification before your first session so you know your expected out-of-pocket cost in writing before therapy begins. Our team in Colorado handles prior authorizations, re-authorizations, and appeals so you can focus on your child. We also offer summer ABA therapy for families who want to maintain progress during school breaks, billed through the same insurance channels as year-round services.
If you’d like a real estimate based on your child’s needs and your insurance plan, reach out to Achieve ABA Therapy Group, and we’ll walk you through the numbers in plain language.
Frequently Asked Questions
These are the questions I hear most often from Colorado families on their first call. If yours isn’t here, please ask—nobody should be guessing at numbers this big.
How much does ABA therapy cost per hour in Colorado?
Standard ABA therapy rates in Colorado run $120 to $150 per hour when billed as a blended program rate. Individual provider components range from $50 to $80 per hour for RBT direct therapy and $120 to $250 per hour for BCBA supervision and assessment.
Does Colorado Medicaid cover ABA therapy?
Yes. Health First Colorado (Medicaid) covers medically necessary ABA therapy for eligible children and teens under 21 through the EPSDT benefit. There are no visit limits on covered care, and out-of-pocket cost for most Medicaid families is zero.
Does private insurance cover ABA therapy in Colorado?
Most state-regulated private plans must cover ABA therapy under Colorado’s autism insurance mandate. Self-funded employer plans (regulated by federal ERISA law) aren’t required to comply with the state mandate, though many do cover ABA. Always verify your specific plan before enrolling.
What’s the cheapest way to access ABA therapy in Colorado?
For families who qualify, Health First Colorado typically provides the lowest out-of-pocket cost. Other low-cost paths include CHP+ for families above Medicaid income thresholds and the CES Waiver for children with substantial support needs.
How much ABA therapy will my child need?
That depends on your child’s age, profile, and goals. Early intervention (under age 5) often involves 20 to 40 hours per week. School-age children may need 10 to 25 hours per week. The recommendation comes from your BCBA after a comprehensive assessment, not from a price quote.
Can I pay for ABA therapy out of pocket if I don’t have insurance?
Yes. Most Colorado providers accept private pay, and some offer sliding-scale fees or payment plans. Private-pay rates typically run $120 to $150 per hour for most providers, though this varies. Ask about scholarship slots and sliding-scale options up front.
Does ABA cost more in Denver than in other parts of Colorado?
Slightly. Denver and Boulder metro rates tend to land at the higher end of the typical range, while providers in smaller cities and rural areas may run a bit lower. The difference is usually less than 10 to 15 percent and rarely affects insurance-billed care, since contracted rates are negotiated by the plan.
What does a typical first-month bill look like with insurance?
Most families with private insurance see a first-month out-of-pocket cost between $200 and $1,500, depending on their deductible status, copay structure, and how many hours their child is receiving. Families on Medicaid generally see no cost. Always run a benefits verification before your first session for an accurate estimate.
