Getting a denial letter after asking your insurance to cover ABA therapy can feel like a punch to the gut. After weeks or months of evaluations, paperwork, phone calls, and waiting, seeing the word “denied” can make it feel like all that effort was for nothing.
The good news is that a denial is often not the end of the road.
Quick Answer
If your insurance denied ABA therapy coverage, you have the right to appeal. Most denials happen because of paperwork issues, missing documentation, or how the request was coded, not because your child doesn’t qualify for help. Start with the denial letter itself, since it tells you exactly what to fix.
Does This Happen in Nevada and Colorado?
Families across Nevada and Colorado are often surprised to learn how common insurance denials can be.
A denial does not necessarily mean your child is ineligible for ABA therapy. In many cases, insurers simply need additional documentation, corrected paperwork, or more information before approving services.
At Best Buds ABA, we help families throughout Nevada and Colorado understand insurance requirements and what steps may be needed to move the process forward.
Start With the Letter in Your Hand
Your denial letter is the most useful document you have right now, even though it might be the last thing you want to look at. Somewhere in it, the insurer has to state the actual reason for the denial. That reason changes everything about what your next move looks like, so before you do anything else, find that line and read it twice.
Missing Paperwork? You’re Not Alone
This is the most common reason ABA therapy gets denied, and honestly, it’s the easiest to fix. Maybe the insurer never received the full evaluation report. Maybe a treatment plan was missing a signature, or the diagnosis wasn’t submitted in the exact format they wanted. None of this means anything is wrong with your child’s diagnosis or your case. It usually just means something didn’t make it into the file. Call your provider’s office and your insurance company and ask, point blank, what’s missing.
Sometimes It’s Just a Billing Error
Coding errors happen more than most parents expect, and they can trigger an automatic denial even when everything else about the request was fine. This one isn’t really yours to fix. It belongs to your provider’s billing team, so loop them in right away and let them know the denial mentioned a coding problem. A quick correction and resubmission often solves this.
When Insurance Questions Whether ABA Therapy Is Needed
This one stings more, since it can feel like the insurer is questioning whether your child actually needs ABA therapy. Usually what’s really happening is the request didn’t include enough supporting evidence, like a detailed treatment plan or notes from the evaluator. A plan exclusion, where ABA therapy isn’t covered under that policy at all, is rarer, but it does happen. Either way, this is the kind of denial worth appealing with the help of your child’s provider, who can submit additional documentation on your behalf.
Here’s What the Appeal Process Usually Looks Like
Most plans start with an internal appeal, where you ask the insurance company to take a second look, usually with more documentation attached. If that doesn’t work, many plans allow an external review, where someone outside the insurance company reviews the case. Timelines and paperwork vary by plan, so your denial letter and a call to your insurer are the most reliable sources for your specific next steps, including any deadlines you’ll want to know about.
