The statute defines &#8220;prevailing factor&#8221; as the primary factor, in relation to any other factor. Before 2005, your work only needed to be a substantial factor. Today, it must be the primary cause.<\/p>\n<p><strong>This is one of the biggest reasons claims get denied.<\/strong> If you had a pre-existing condition and then got hurt at work, the insurer may argue that your job was not the prevailing factor.

What qualifies as a work injury in Missouri?<\/h4>\n<p>A compensable work injury falls into one of three categories: an accident (an unexpected traumatic event during a single work shift), an occupational disease (such as mesothelioma from toxic exposure), or a repetitive trauma injury (like carpal tunnel from repeated motion). The work-related accident must be the prevailing factor in causing both the medical condition and disability.<\/p>\n<h4>2. How long do I have to report an on-the-job injury in Kansas City?<\/h4>\n<p>Missouri law requires written notice to your employer within 30 days of the accident. For occupational diseases and repetitive trauma, the 30-day period begins on the date of diagnosis of the condition (Missouri Revised Statutes \u00a7287.420). Missing this deadline may jeopardize your claim.<\/p>\n<h4>3. Can I still get workers&#8217; comp benefits if I had a pre-existing condition?<\/h4>\n<p>Potentially, yes. However, you must show that the workplace accident was the prevailing factor in causing both your medical condition and disability. Strong medical documentation linking the work event to your current condition is essential.<\/p>\n<h4>4. What happens if alcohol or drug use was involved in my workplace injury?<\/h4>\n<p>Under \u00a7287.120(6), if substance use in violation of the employer&#8217;s written policy was the proximate cause of the injury, benefits are forfeited. If present but not the proximate cause, benefits may be reduced by 50%. If the employee was legally intoxicated, there is a rebuttable presumption that alcohol use was the proximate cause.<\/p>\n<h4>5. Does workers&#8217; comp cover mental health injuries in Missouri?<\/h4>\n<p>It can, but the standard is strict. The work-related stress must have been extraordinary and unusual based on objective standards and actual events. Mental injuries caused by routine employment actions like discipline or termination are excluded.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"you-deserve-answers-and-a-team-that-listens\"><\/span>You Deserve Answers and a Team That Listens<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>Figuring out whether your injury qualifies for workers&#8217; compensation in Missouri can feel overwhelming, especially when you are already in pain and worried about bills.<\/strong> The rules are strict, the deadlines are real, and insurance companies have entire teams working to protect their bottom line.
