When a worker gets injured on the job, understanding how pre-existing conditions impact a workers’ compensation claim is important. In Missouri, workers’ compensation benefits are available to employees who suffer injuries at work, but pre-existing conditions may complicate the process. This blog will explain when a pre-existing condition qualifies for coverage and how to build a strong claim.
What qualifies as a pre-existing condition?
A pre-existing condition refers to any health issue or injury that occurred before the workplace accident. This could include past back injuries, joint problems, or long-term conditions like arthritis or diabetes. Pre-existing conditions won’t automatically disqualify a workers’ compensation claim, but they can affect the scope of benefits and coverage.
When are pre-existing conditions covered?
Missouri workers’ compensation laws allow coverage for pre-existing conditions if a work-related injury worsens the condition. For example, if a worker with an existing knee injury suffers a new injury that aggravates the old issue, workers’ comp benefits may still apply. The injury must be directly related to the work environment, and the condition must have worsened because of the job-related incident.
How to build a workers’ comp claim with a pre-existing condition
To strengthen a claim that involves a pre-existing condition, workers should document everything thoroughly. Report the injury to the employer immediately and inform the doctor about any prior health issues. Medical records play a key role in showing how the work injury has worsened the pre-existing condition. Also, explain clearly how the accident occurred and how it contributed to the worsening of the condition.
Workplace injuries can be complex, but understanding how pre-existing conditions affect workers’ compensation can help workers secure the benefits they need.
