If you’ve recently looked into ABA therapy for your child, or for yourself, you’ve probably already done some mental math about what it might cost. And if the numbers felt daunting, you’re not alone. ABA therapy is intensive, and it’s not cheap. The good news is that in Colorado, most insurance plans are required by law to cover it. The not-so-good news is that “covered” doesn’t always mean “simple,” and the path from diagnosis to approved services can take some navigating.
This post breaks down how insurance coverage for ABA therapy works in Colorado. We’ll discuss what to look for in your plan and how to advocate for your family when the process gets complicated.
Colorado Law Requires Coverage
Colorado is one of the states with a mandated autism insurance law. Under Colorado law, most private health insurance plans sold in the state are required to cover ABA therapy and other autism-related services when there is a diagnosis of autism spectrum disorder. This mandate has been in place since 2010 and has been strengthened over the years.
What this means practically: if you have a private insurance plan regulated by the state of Colorado, your insurer cannot simply refuse to cover ABA therapy. They cannot cite “experimental” or “not medically necessary” as grounds for denial when your child has an autism diagnosis.They are required to provide coverage.
The important caveat is that not every insurance plan is subject to Colorado state law. Self-funded employer plans, which are common with large employers, are regulated by federal law instead of state law, and they are not bound by Colorado’s autism mandate. If your insurance comes through a large employer, it’s worth asking your HR department whether the plan is fully insured or self-funded, because the answer changes what you’re entitled to.
What ABA Coverage Actually Looks Like
Insurance coverage for ABA therapy typically works like this: your child’s BCBA submits a treatment plan, the insurer reviews it and either approves or requests changes, and therapy begins once the insurer grants authorization. From there, coverage usually hinges on medical necessity — the insurer wants to see that therapy goals are clinically appropriate and that the provider is tracking progress.
Most plans cover ABA under behavioral health benefits rather than medical benefits, which matters because the cost-sharing structure (deductibles, copays, out-of-pocket maximums) may differ depending on which bucket it falls into.
Some things to clarify with your insurance plan before you start:
Prior authorization. Almost all plans require prior authorization before ABA therapy begins. This means your provider will submit documentation, including the autism diagnosis and a proposed treatment plan, and the insurer will approve a certain number of therapy hours for a set period of time. Insurers typically renew authorization every six to twelve months.
In-network vs. out-of-network. Insurance coverage is almost always significantly better when you use an in-network ABA provider. Out-of-network providers may be covered at a much lower rate or not at all, depending on your plan. When you’re choosing an ABA provider, confirming they are in-network with your insurance is one of the first questions to ask.
At Optimum Behavior Guidance Consulting, we help you navigate the process.
Hour limits. Some plans cap the number of ABA therapy hours covered per year. Others don’t impose a hard cap but require ongoing authorization based on medical necessity. Colorado’s parity laws limit the ability of insurers to impose restrictions on behavioral health services that don’t apply to medical services, so families can sometimes challenge overly restrictive hour limits.
Deductibles and cost-sharing. Even with coverage, you’ll likely have a deductible to meet before insurance kicks in, and may have copays or coinsurance on top of that. ABA therapy is often one of the larger line items in a family’s healthcare spending, so knowing your out-of-pocket maximum is important.
The Prior Authorization Process
Prior authorization is often the step families find most frustrating, and it helps to know what to expect. Your ABA provider handles most of the paperwork. They’ll submit the diagnosis documentation, the initial assessment, and a treatment plan that outlines targeted skills. They will also include their recommendation on number of hours per week.
The insurer reviews the request and either approves it, requests additional information, or denies it. Denials aren’t always final. If your child’s treatment plan is denied, you have the right to appeal. Many denials are overturned on appeal — especially when the appeal includes supporting documentation from the treating clinician.
One thing that helps: make sure your ABA provider is experienced with the authorization process for your specific insurance plan. Providers who work regularly with a given insurer understand what that insurer wants to see in a treatment plan. This can reduce back-and-forth and speed up the approval timeline.
When Coverage Gets Complicated
Even with a mandate and an approved authorization, families sometimes run into problems mid-treatment. Common issues include:
Mid-year authorization denials. An insurer may deny a renewal authorization if they determine that services are no longer medically necessary, even when the family and provider disagree. If this happens, your provider can request a peer-to-peer review — where your child’s BCBA speaks directly with the insurer’s clinical reviewer — and you can file an internal or external appeal.
Benefit carve-outs. Some plans carve out behavioral health benefits to a separate managed care organization. This means your medical insurance and your behavioral health benefits may be managed by different companies, which can complicate coordination of care and require separate authorizations.
Network adequacy issues. Some parts of Colorado limit in-network ABA provider options. If you cannot access an in-network provider within a reasonable distance or timeframe, you may be able to request an out-of-network exception. This is worth pursuing rather than assuming the answer is “No.”
What to Do First
If you’re just beginning to figure out your coverage, here’s a straightforward starting point:
Call the member services number on the back of your insurance card and ask specifically about ABA therapy benefits. First, you should ask if your company requires prior authorization. And, ask whether there are hour limits, and who the in-network ABA providers are in your area. Take notes and get a reference number for the call.
From there, when you contact an ABA therapy provider, they should be able to do a benefits verification — a detailed check of your specific plan’s coverage — before services begin. A good provider will walk you through what your plan covers, what your estimated out-of-pocket costs will be, and what the authorization timeline typically looks like.
A Note on Adults and ABA Therapy
Colorado’s insurance mandate applies to children and adolescents. Yet adults with autism who need ABA therapy can face different coverage landscapes. Some plans do cover ABA for adults. Particularly when you can demonstrate medical necessity. If you’re looking for ABA therapy for an adult family member, it’s worth doing a benefits check rather than assuming coverage won’t apply.
