Workers Compensation Appeals: How to Fight a Denied Claim in Missouri

A denied workers’ comp claim can feel like a dead end—but it’s not. Missouri law gives injured employees the right to challenge claim denials through a formal workers compensation appeals process. Whether your claim was denied due to a paperwork error or a dispute about how your injury occurred, you may still be eligible for the workers compensation benefits you deserve.

At OnderLaw, we help injured workers fight back after wrongful denials. Our experienced St. Louis workers compensation attorneys understand the complex appeals system and how to build the strongest case possible.


Why Are Workers Comp Claims Denied?

Missouri’s workers compensation programs operate under a no-fault system. You don’t have to prove your employer did anything wrong to receive benefits. But that doesn’t stop insurers from looking for reasons to deny claims.

Common Reasons for Denial:

  • You didn’t report your injury within 30 days

  • Paperwork was incomplete or submitted late

  • Your employer disputes that the injury is work-related

  • There’s a lack of medical evidence

  • The insurer claims your condition is pre-existing

Even small errors or inconsistencies can give the insurance company ammunition to reject your claim. But a denial is not the end of the road.

Filing a Workers Compensation Appeal in Missouri

If your claim is denied, you can file a Request for Review with the Missouri Division of Workers’ Compensation. This must be submitted within 20 days of receiving your denial notice​.

Key Steps in the Missouri Appeals Process:

  1. File a Request for Review (within 20 days)

  2. Case may move to mediation to resolve the issue informally

  3. If unresolved, the case proceeds to a hearing before an administrative law judge

  4. If the judge denies your appeal, you can request a review by the Missouri Labor and Industrial Relations Commission within 20 more days

  5. Further appeals can go to the Missouri Court of Appeals, and potentially to the Missouri Supreme Court

Each level of appeal requires strict adherence to deadlines and procedures. This is where having an attorney familiar with the compensation act, administrative law judges, and the workers compensation appeals board can make or break your case.

What Happens During the Appeals Process?

Mediation

Some cases are resolved early through a mediation session arranged by the state. This is an opportunity to negotiate with the insurer outside of court.

Hearing Before an ALJ

If mediation fails, your appeal goes before an administrative law judge (ALJ). You’ll present your case, introduce evidence, and possibly call witnesses.

Commission Review

If the ALJ denies your claim, you can escalate to the Labor and Industrial Relations Commission. These officials are appointed by the governor and serve as the state’s workers compensation appeals board.

Court of Appeals

Still denied? You can file with the Missouri Court of Appeals within 30 days. From there, your appeal could reach the state supreme court who decides appeals, though most cases resolve before that point.


Why Legal Help Matters

The workers compensation appeals process is legally intense, time-sensitive, and often stacked against injured workers. Without proper representation, your chances of reversing a denial drop significantly.

At OnderLaw, we understand how the system works—and how insurers attempt to exploit it. We handle all aspects of your case, from filing the review form to presenting arguments before a judge.
