What Happens if My Colorado Workers’ Compensation Claim is Denied?

 Posted on March 19, 2026 in Workers' Compensation

Colorado employers are required by law to carry workers’ compensation insurance, which pays for medical care and lost wages when an employee is hurt on the job. But getting those benefits is not always easy. According to the Colorado Department of Labor and Employment, more than 32,000 workers’ compensation claims are reported in the state each year, and some of these claims lead to disputes over benefits or coverage. If your claim was denied in 2026, a Larimer County, CO workers’ compensation lawyer can help you understand your options and fight for the benefits you are owed.

Why Was My Workers’ Compensation Claim Denied?

A workers’ comp claim can be denied for several different reasons. Knowing why yours was denied is the first step toward pushing back. Some reasons are procedural, meaning a deadline was missed or a form was filled out incorrectly. Others go to the heart of the claim, such as whether the injury actually happened at work. Either way, a denial does not mean you have no options.

Here are some of the most common reasons for workers’ compensation denials: 

• A delay in reporting or filing: Under C.R.S. § 8-43-102, you must notify your employer in writing within 10 days of a workplace injury. This deadline changed in 2022, which used to be four days. You also have two years from the date of injury to file a formal claim. Missing either deadline can lead to a denial, though limited exceptions may apply.
• Not enough evidence that the injury was work-related: If your employer or their insurance company does not believe your injury happened at work or was caused by your job, they may argue they owe you nothing. This is one of the most common reasons claims get denied.
• Not enough evidence of treatment: If you did not see a doctor after your injury, the insurer may question whether you were really hurt. Even if you did get treatment, gaps in your medical records can be used against you. Seeing a doctor as soon as possible after a workplace injury protects both your health and your claim.
• A pre-existing condition argument: Insurers sometimes claim that your injury was caused by a condition you already had before starting your job. Colorado law does allow you to recover benefits if your work made a pre-existing condition worse, but you will need solid medical records to show that connection.
•  Disputes over where the injury happened: If your employer claims the injury did not happen at work, on the clock, or during a work-related task, they may deny the claim. This comes up often with remote workers, injuries during work travel, or accidents at company events.

If you are not sure which reason applies to your denial, the notice you received should explain the basis for it. An attorney can help you review that notice and figure out the strongest way to respond.

What Can You Do After a Workers’ Comp Denial in Colorado?

A claim denial is not the end. You have the right to challenge it, and many workers who appeal end up getting benefits they were first told they could not have.

After a denial, the next step is usually filing an Application for Hearing with the Office of Administrative Courts. At this hearing, both sides present their evidence to an administrative law judge, who then decides the outcome. Before the hearing takes place, you can ask for a prehearing conference. This is a less formal meeting where both sides share documents and talk through the issues. Many cases settle at this stage, which can save time and stress for everyone involved. Workers in Fort Collins and throughout Larimer County go through this same process, and having local representation familiar with the Office of Administrative Courts can make the experience less overwhelming.

If you are not happy with the judge’s decision, you can appeal to the Industrial Claim Appeals Office. After that, you can take your case to the Colorado Court of Appeals. Each step has a strict deadline, so it is important to act quickly after any decision you want to challenge. Waiting too long at any stage can close the door on your right to keep fighting. An attorney can help you track these deadlines and make sure nothing falls through the cracks.

Frequently Asked Questions About Denied Workers’ Comp Claims

How long do I have to appeal after a denial?

If a judge issues an order you disagree with, Colorado Revised Statutes section 8-43-301 gives you 20 days from the date the order was mailed to file a Petition to Review. If you miss that window, you may lose your right to appeal altogether. Do not wait.

Can my employer punish me for fighting a denial?

An employer cannot legally fire you just because you filed a workers’ compensation claim. In Colorado, this type of retaliation may give you the right to bring a wrongful termination claim.

What if the insurer only disputes part of my claim?

You can challenge any portion of a denial, not just a full rejection. Insurers sometimes approve basic benefits but deny specific treatments such as surgery, physical therapy, or a certain number of weeks of wage replacement. You have the right to dispute any part of that decision.

Can I handle a workers' comp appeal on my own?

You can manage a claim on your own, but it is risky. Insurance companies have attorneys working for them from the start. At a formal hearing, you will be expected to present evidence, question witnesses, and argue your case under the same rules as an attorney would. One misstep, such as a missed deadline, a poorly worded statement, or a gap in your medical records, can cost you the benefits you are owed. Having an attorney on your side levels the playing field.

No matter which question applies to your situation, the most important thing is to act before deadlines pass. The workers’ comp system in Colorado has many moving parts, and having someone in your corner who knows the process can make a real difference.
