ABA Therapy in Colorado

Who provides ABA in Colorado

Every provider below is a named practice with a website that resolves — we removed a large number of listings in August 2026 that turned out not to describe real businesses, and these are what survived that. We do not rank them, take payment for placement, or claim to have assessed the quality of anyone’s clinical work. Verify licensure and current availability yourself before you commit.

How ABA gets paid for in Colorado

There are three routes, and most families end up using more than one.

Private insurance

Colorado requires state-regulated health plans to cover autism treatment under C.R.S. § 10-16-104(1.4), running to no age limit in the current law. Colorado originally covered children under 19; Senate Bill 15-015 folded autism into the state's mental health parity requirements effective January 2017, and the age ceiling went with it. The caps, the exact wording to quote, and what to do when a plan ignores it are on the Colorado insurance page.

One caveat matters more than any other and applies in every state: if your employer’s plan is self-funded, federal ERISA law generally exempts it from the state mandate. Roughly six in ten covered workers are on such a plan. Ask HR which yours is before you assume the mandate protects you — this is the single most common reason a family is told the law does not apply to them.

Medicaid

Health First Colorado covers ABA for members under 21 through EPSDT, separately from this mandate. 9 of the 15 providers listed above state that they accept it.

The Medicaid waiver

Colorado runs Children's Extensive Support (CES) for children; HCBS-DD and Supported Living Services for adults, and the typical wait is No state waitlist for CES; around 7 years for the adult DD waiver. How it works here, who administers it, and how to apply is on the Colorado waiver page. The thing to know now: in most states the application date is what sets your place in the queue, so applying early costs nothing and waiting can cost years.

What to ask before you sign

ABA providers vary enormously — in hours demanded, in supervision, and in philosophy. These are the questions that actually separate them.

• How many hours are you recommending, and why that number? “Forty hours because that is what the research says” is a weak answer; the studies behind that figure are decades old and were not about every child.
• Who supervises, and how often will a BCBA actually be in the room? Ask for the name and check it on the BACB registry.
• What happens when my child refuses or is distressed? This is the question that most reveals a provider’s approach. You are listening for whether refusal is treated as information or as something to be overcome.
• Do you work on communication, including AAC? A program that treats a non-speaking child as having no way to communicate is not a good program.
• What is your current waitlist, in weeks? Ask for a number, and ask again in a month. For context, the Colorado waiver itself typically runs no state waitlist for ces; around 7 years for the adult dd waiver, so a clinic quoting a shorter private-pay wait is not unusual.
• Will you bill my insurer directly, and what is my share? Get the answer in writing before the first session, not after. In Colorado you can point to C.R.S. § 10-16-104(1.4) if a plan claims autism treatment is not a covered benefit, and complain to the Colorado Division of Insurance on 303-894-7490 if it persists.
• Do you take Colorado Medicaid, and are you taking new Medicaid clients right now? Those are two different questions, and the second one is the one that decides whether you get seen. 9 of the providers above say they accept it.

About ABA itself

ABA is the most widely insured autism therapy in the United States and, for many families, the only intensive support an insurer will pay for. It is also genuinely contested. A significant number of autistic adults describe harm from compliance-based programs, particularly older ones that treated stimming or avoiding eye contact as behaviors to eliminate. Plenty of parents report their child thriving. Both of those things are true at once, and a directory that told you only one of them would not be worth much to you.

What follows from that is practical rather than ideological: providers differ, so ask the questions above, watch a session if you can, and treat your child’s distress as data rather than as resistance to be worked through. If ABA is not right for your family, occupational therapy, speech and language therapy, and developmental approaches such as DIR/Floortime and the Early Start Denver Model are real alternatives, though insurance coverage for them is patchier.
