An insurance company may deny a claim for a variety of reasons, such as if the employee did not notify their employer of their injury in a timely manner, or if there is a dispute as to whether the injury is work-related. A Bremen workers’ comp attorney could help an individual through the appellate process.The first step in challenging a denied claim is to file a notice of claim using Form WC-14. The deadline to file a notice of claim differs depending on whether any medical treatment has already been provided, or if the insurance company has already made any disability payments. During mediation, a workers’ compensation judicial officer may order the parties to seek an agreement.
