ABA Insurance Denial and Appeals Help in Colorado
A denial is upsetting, but it is also a document. The reason on that notice tells your family what to check next.
ABA can be denied even when a child clearly needs help. Sometimes a record is missing. Sometimes the payer disagrees with the requested hours. Sometimes the problem is timing, network status, or a plan rule. Budding Futures helps Colorado families slow down and read what the notice is actually saying.
Why ABA gets denied
A denial does not always mean the payer is saying no forever. It may mean the request was incomplete, the dates were wrong, or the payer wants different clinical records. Other denials are harder. They may involve medical necessity, requested hours, network rules, or plan exclusions. The letter matters because it tells you which problem you are actually dealing with.
What to keep in one place
Keep the denial notice, card, diagnosis records, assessments, treatment plans, auth letters, and any emails from the payer. If you called the company, write down the date and reference number. It feels tedious, but it can save time if someone later asks what already happened.
Medicaid and private plans are not the same
Health First Colorado sends determination notices and appeal information when a PAR is denied. Private plans regulated by Colorado give you 180 days to file an internal appeal, then four months after that answer to ask for an independent external review. If your employer pays claims itself, federal rules apply and the floor is still 180 days. Before sending anything back, read the instructions on the notice and make sure the appeal is going to the right place.
How Budding Futures helps
Budding Futures can help parents understand common denial issues and what records may be needed for the next review. The team cannot promise a denial will be overturned. What they can do is help families avoid guessing, gather the right paperwork, and understand the next administrative step.
What should you bring to the first call?
Bring the insurance card, the child's diagnosis or evaluation if you have it, any denial or authorization letter, and a short note about what you need help with first. If Medicaid and private insurance are both involved, bring both cards. A clear first call depends on the actual plan details, not a guess from a search result.

How the ABA insurance appeal process works
An insurance appeal asks your health plan to look again after a claim was denied. The appeal process has the same shape for almost every insurance plan. First you review the denial and its stated denial reasons. Then you file an internal appeal with the plan. If the answer is still no, you ask for an external appeal, where an independent reviewer decides. If waiting would put your child's health at risk, ask for an expedited appeal at each stage.
Read the codes too. An Explanation of Benefits usually lists a denial code and the billing codes for the service. ABA is billed under CPT codes 97151 through 97158. Check that the CPT code, the dates and the hours on the notice match what your provider asked for, because some claim denials are paperwork mismatches and not a judgment about your child's autism treatment.
ABA appeal deadlines in Colorado, by type of plan
Which rules apply depends on who pays the claims. Your denial notice and plan documents say which kind of plan you have. Every deadline below comes from a law, a regulation or a government page, linked in the table. This is general information, not legal advice, and the notice you received controls.
| Your plan | First step and deadline | How fast they must answer | If the answer is still no |
|---|---|---|---|
| Private plan regulated by Colorado (fully insured) | File an internal appeal "Within 180 calendar days after the date of receipt of a notice of an adverse determination" (Colorado Insurance Regulation 4-2-17). | 30 days if the therapy has not happened yet, 60 days if it has, 72 hours if it is urgent. | Ask for an independent external review "within four months after receiving notification of the denial" of your internal appeal (C.R.S. 10-16-113.5). You send the request to the insurer, which passes it to the Colorado Division of Insurance. The reviewer decides in 45 days, or 72 hours if expedited. |
| Employer plan that pays its own claims (self-funded) | Federal rules apply. The U.S. Department of Labor: "you have at least 180 days to file an appeal (check your Summary Plan Description or claims procedure to see if your plan provides a longer period)." DOL guide, 29 CFR 2560.503-1 | For a plan with one appeal level: 30 days before the service, 60 days after it, 72 hours if urgent. | External review, requested within four months, decided in 45 days or 72 hours if expedited (29 CFR 2590.715-2719). Your denial notice says which review process your plan uses. |
| Health First Colorado (Medicaid) | A written appeal to the Office of Administrative Courts. State pages give two deadlines: 30 calendar days on the pediatric behavioral therapies page and 60 days on the Health First Colorado appeals page and in state law. Go by the date on your Notice of Action and file as early as you can. | "In most cases the judge will make a written decision in 20 days." | Your provider can also ask for a PAR Reconsideration. To keep a service that was already approved: "the Office of Administrative Courts must receive your request for an appeal no later than 10 days from the date of action." A first request that is denied has no continuation. |
| TRICARE | "Submit routine appeals within 90 calendar days of when you receive the denial letter." Rushed appeals: within three calendar days. TRICARE West Region page, updated March 19, 2026. Check the region on your letter. | A reconsideration decision "normally" within 60 days (32 CFR 199.10). | A formal review, requested within 60 days of the reconsideration notice. |
What Colorado law says about ABA coverage
State lawAll health benefit plans issued or renewed in this state must provide coverage for the assessment, diagnosis, and treatment of autism spectrum disorders for a child pursuant to this subsection (1.4).
The same section names "applied behavior analysis" as part of treatment. It also says coverage is "subject to all terms, conditions, definitions, restrictions, exclusions, limitations, and utilization review" of the plan. In plain words: a state-regulated plan has to cover ABA for autism, and it can still question the hours or the records. That is what an appeal is for.
Mental health parity: a second question to ask
Federal agencyThe Paul Wellstone and Pete Domenici Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA) is a federal law that generally prevents group health plans and health insurance issuers that provide mental health or substance use disorder (MH/SUD) benefits from imposing less favorable benefit limitations on those benefits than on medical/surgical benefits.
HealthCare.gov puts the same idea in plain words: limits on behavioral health services "can't be more restrictive than limits applied to medical and surgical services," and that includes "limits to the number of days or visits covered." How parity applies to one limit on ABA depends on your plan. It is a fair question for an appeal: ask the plan to explain, in writing, how the limit it applied compares with the limits it puts on medical care. You can also ask your state insurance regulator, the Colorado Division of Insurance, about a state-regulated plan.
An ABA appeal letter you can copy
This is written for a private plan's internal appeal. Fill in the brackets. The parts come from federal guidance: HealthCare.gov says to "write to your insurer with your name, claim number, and health insurance ID number" and to "Submit any additional information that you want the insurer to consider, such as a letter from the doctor." For Health First Colorado and TRICARE, use the form or letter described on your notice.
Keep your original documents and send copies. Write down the date you sent it and how. If you phone the plan, note the day, the time and the name of the person you spoke to.
Can ABA therapy be denied even with an autism diagnosis?
Yes. A diagnosis helps explain need, but the payer may still deny a request because of records, authorization rules, hours, network status, or plan limits.
What should I do after an ABA insurance denial?
Save the denial letter, read the reason, gather the supporting records, and follow the appeal instructions listed by that payer.
How long do I have to appeal an ABA denial in Colorado?
It depends on the plan. Colorado-regulated private plans and employer self-funded plans give at least 180 days to file an internal appeal. TRICARE gives 90 calendar days for a routine appeal. For Health First Colorado, state pages give 30 days in one place and 60 in another, so go by your Notice of Action and file early.
Does Colorado law require insurance to cover ABA therapy?
Yes, for state-regulated plans. Colorado law requires health benefit plans issued or renewed in the state to cover the assessment, diagnosis and treatment of autism spectrum disorders for a child, and it names applied behavior analysis. The plan can still review whether the hours requested are medically necessary, which is why denials happen and appeals exist.
