The Short Answer
A denied workers comp claim in Colorado means your employer’s insurance company has refused to pay medical bills, lost wages, or other benefits related to your workplace injury. The denial will arrive as a formal “Notice of Contest” explaining why the insurer rejected your claim — common reasons include missed reporting deadlines, disputes about whether the injury happened at work, or insufficient medical documentation. Colorado law sets a specific deadline for filing an appeal — consult an attorney immediately to confirm the window for your case.

When you open the mail and see that your workers’ comp claim was denied, it feels like getting punched twice — once by the injury itself, and again by the system that’s supposed to protect you. But here’s what most injured workers in Colorado Springs don’t realize: a denial isn’t the end of the story. It’s the insurance company’s opening position in what might become a negotiation or hearing.
That denial letter isn’t a mystery. It’s a document with specific legal meaning, and understanding what it says — and doesn’t say — determines what you can actually do about it.
What a Colorado Workers’ Comp Denial Letter Actually Contains
When a Colorado workers’ compensation insurer denies your claim, they must file a formal document called a Notice of Contest with the Division of Workers’ Compensation. You’ll receive a copy. This isn’t just a form letter saying “no.” It must contain:
- The specific reasons for the denial — vague statements won’t hold up
- Which benefits are being denied (medical treatment, lost wages, permanent disability, etc.)
- The facts the insurer relies on to support the denial
- Your right to appeal and the applicable deadline — consult with an attorney to confirm the time limit for your situation
Read that document carefully. The reason for denial dictates your next move. A claim denied because “injury not work-related” requires different evidence than one denied for “failure to report within 10 days.”
The Most Common Reasons Colorado Workers’ Comp Claims Get Denied
Missed Reporting Deadlines
Under Colorado law, you must report a work injury in writing within 10 days to your employer. This deadline was extended from four days by House Bill 22-1112, but it’s still tight. If you wait three weeks to report your back injury from lifting boxes at a Fountain warehouse, the insurer will likely deny based on late notice.
Late reporting doesn’t automatically kill your claim, but Colorado law allows insurers to reduce your benefits as a penalty. Bradford Pelton PC has successfully argued that delayed reporting caused no prejudice to the insurer when medical records clearly document an on-the-job injury, but you’re fighting uphill.
For occupational diseases — conditions that develop over time, like carpal tunnel from repetitive assembly work at a Falcon manufacturing plant — you must provide written notice within 30 days after the first distinct manifestation of the disease. This is a different standard than for sudden injuries, and determining when the “first distinct manifestation” occurred often requires medical documentation linking your symptoms to workplace exposure.
Disputes About Whether the Injury Was Work-Related
This is the most fought-over issue in denied workers comp claims. Colorado operates a no-fault system, meaning you can still get benefits even if you were partially at fault for the accident — but the injury must still “arise out of and in the course of employment.”
Insurers deny claims when they argue:
- The injury happened off the clock (leaving the Monument job site for lunch, injured in parking lot)
- The activity wasn’t work-related (horseplay during break, personal errands)
- A pre-existing condition caused the problem, not a work incident
- There’s no credible evidence the injury happened the way you described
These cases often come down to witness statements, surveillance footage, and medical opinions linking your condition to work activities.
Insufficient Medical Evidence
You slipped on ice outside your Colorado Springs office building, felt immediate pain, but didn’t see a doctor for two weeks because you thought it would get better. By the time you file a claim, the insurer argues there’s no proof the fall caused your current symptoms.
Colorado workers’ comp claims require medical documentation that:
- Confirms the injury or condition exists
- Establishes a causal link between work activities and the injury
- Supports the need for treatment or time off work
Weak or delayed medical evidence invites denials. This is why treating with an employer-approved physician from the designated provider list matters — insurers fight harder against treatment from doctors they didn’t authorize.
Pre-Existing Conditions
Having arthritis, prior back surgery, or an old shoulder injury doesn’t disqualify you from workers’ compensation. But it does complicate your claim. Insurers will argue a workplace incident merely aggravated a pre-existing condition, not that work caused a new compensable injury.
The legal standard: if work activities accelerated, aggravated, or combined with a pre-existing condition to produce disability or need for treatment, you’re still entitled to benefits. Proving that distinction requires medical opinions, often from independent medical examiners, explaining what portion of your current limitations stem from the work incident versus baseline degeneration.
Full Denial vs. Partial Denial vs. Requests for More Information
Not all denial letters mean the same thing.
A full denial rejects the entire claim — no medical coverage, no wage replacement, nothing. The insurer is taking the position that this is not a compensable workers’ compensation case.
A partial denial (or partial admission) accepts some parts of your claim but denies others. Example: the insurer agrees to pay for your broken wrist from a fall off scaffolding at a Woodland Park construction site but denies your claim that the same fall caused a concussion because there’s no documented head impact.
A request for more information typically involves the insurer filing a Notice of Contest to preserve their right to dispute benefits later while indicating they need additional medical records, witness statements, or clarification about when and how the injury occurred before making a final decision. These requests can be legitimate or stalling tactics.

Colorado’s Workers’ Comp Appeals Process Timeline
If your claim is denied, Colorado law sets time limits for challenging that denial through the Division of Workers’ Compensation. Missing these deadlines can bar your right to appeal. Contact an attorney immediately upon receiving a denial to confirm the specific deadline that applies to your case and preserve your rights.
Once you apply for a hearing, the Division schedules either:
- An expedited hearing for urgent disputes about ongoing medical treatment
- A standard hearing for wage loss, permanent disability, and other issues
Scheduling timelines vary depending on case complexity and Division resources.
Before the hearing, you’ll go through discovery — exchanging witness lists, medical records, and expert opinions. The hearing itself resembles a trial. Both sides present evidence. An Administrative Law Judge (ALJ) issues a written order either upholding the denial or ordering the insurer to pay benefits.
If you lose at the hearing level, you can appeal to the Industrial Claim Appeals Office (ICAO), and potentially to the Colorado Court of Appeals after that. Each level adds months to years.
The insurer knows most injured workers can’t afford to wait years for benefits. That’s leverage. That’s also why having an attorney who handles appeals regularly — someone like Alex Kerr, who personally manages each case through the entire process — makes a difference insurers feel.
When an Attorney Can Actually Help With a Denied Claim
Self-appealing a workers’ comp denial is possible. The Division of Workers’ Compensation provides forms and instructions. Some denials — especially those based on obvious insurer mistakes or clear-cut medical evidence — can be resolved without an attorney.
But most denied workers comp claims in Colorado involve contested facts, conflicting medical opinions, or legal arguments about what “arising out of employment” actually means in your specific situation. An attorney helps by:
- Obtaining independent medical evaluations that address the exact reasons for denial
- Developing witness testimony from coworkers who saw the accident or your work conditions
- Cross-examining the insurer’s doctors at hearing to expose bias or gaps in their opinions
- Navigating procedural rules that can sink a claim on technicalities
Bradford Pelton PC handles both workers’ compensation and personal injury cases. That dual focus matters when your workplace injury might also support a third-party liability claim — for example, if you were injured by a defective machine at a Security-Widefield factory, or hurt in a car accident while driving for work. Recovering compensation through multiple avenues often makes more financial sense than fighting only within the workers’ comp system.
We offer a free consultation to review your denial letter and explain whether appealing makes practical sense given the strength of your evidence and the reasons stated in the Notice of Contest.
How Often Colorado Workers’ Comp Claims Are Denied — and How Often Appeals Succeed
Comprehensive statewide statistics on workers’ compensation denial rates and appeal outcomes in Colorado are not published in a single public database. However, data from Division case filings and industry reports suggest that a meaningful percentage of claims face some form of initial denial or contest from insurers.
Of denied claims that proceed to contested hearings, outcomes vary significantly depending on the legal and factual issues involved. Claims denied for missed deadlines or lack of medical causation face steeper challenges. Claims denied based on disputed facts about how an accident occurred — where witness credibility matters — may succeed more often when the injured worker is represented and prepared.
What those general patterns don’t capture: many denied claims settle before hearing. The insurer may agree to pay medical bills and a reduced lump sum rather than risk a full hearing loss. An experienced attorney knows when settlement makes sense and when pushing to hearing is worth the fight.

Frequently Asked Questions
What does a denied workers’ comp claim mean?
A denied workers’ comp claim means the employer’s insurance company filed a Notice of Contest rejecting your claim for benefits. The denial must state specific reasons — such as late reporting, disputed work-relatedness, or insufficient medical proof. Colorado law sets time limits for challenging a denial, and missing those deadlines can permanently bar your right to appeal. Contact an attorney immediately upon receiving a denial to confirm the deadline for your case and preserve your appeal rights.
How often are workers’ comp claims denied?
Precise statewide denial statistics for Colorado workers’ compensation claims are not published in a readily accessible public database. Industry sources and Division filings suggest that a significant percentage of claims face some form of initial denial or insurer contest. Many of these denials are later resolved through settlement negotiations or hearings. Outcomes at contested hearings depend heavily on the strength of medical evidence, witness testimony, and the specific legal issues in dispute. Representation by an experienced attorney often improves outcomes in disputed cases.
Can a hernia be covered under workers’ comp?
Yes, a hernia can be covered under Colorado workers’ compensation if it resulted from a sudden work-related strain, lifting incident, or trauma during employment. However, insurers frequently contest hernia claims by arguing the condition was pre-existing or degenerative. You’ll need medical documentation connecting the hernia to a specific work event and showing it wasn’t simply a gradual development. Hernia claims denied on causation grounds often require independent medical opinions to win on appeal.
Is bursitis covered under workers’ compensation?
Bursitis can be covered under Colorado workers’ compensation when caused or aggravated by repetitive work activities, a specific work injury, or prolonged job-related positions that inflamed the bursa. Common examples include shoulder bursitis from overhead assembly work or knee bursitis from kneeling on concrete during flooring installation. Insurers often deny bursitis claims by characterizing the condition as degenerative or unrelated to work, requiring medical opinions that establish a causal connection between job duties and the inflammation.
What happens if I miss the deadline to appeal a workers’ comp denial in Colorado?
Missing the deadline to file an application for hearing after receiving a Notice of Contest can permanently bar your right to challenge the denial. Colorado’s Division of Workers’ Compensation strictly enforces appeal deadlines. In rare cases, you may be able to reopen the claim based on a significant change in medical condition or newly discovered evidence, but those exceptions are narrow. If you received a denial letter, consult an attorney immediately to confirm the applicable deadline and preserve your appeal rights.
Can I still get workers’ comp benefits if I was partly at fault for my injury?
Yes. Colorado workers’ compensation is a no-fault system, meaning you can receive benefits even if your own negligence contributed to the injury, as long as the injury arose out of and occurred during the course of your employment. The exception: if you were intoxicated or willfully violated a known safety rule with the intent to injure yourself or another person, benefits may be denied. Partial fault for an accident — such as not wearing gloves or rushing a task — generally does not disqualify you from coverage.
