When a claim is filed properly and approved by the insurance company, you will likely start to receive benefits, including coverage for medical expenses and a portion of your lost income. The process can become more complicated, resulting in your benefits being delayed, if your claim is denied by the insurance company. The following are common reasons that a claim may be denied:nInsufficient proof that the injury or illness is work-related. If your employer argues that you were not performing official work duties at the time of the accident, or that your injury was directly related to a pre-existing injury or illness, your Workers’ Compensation claim may be denied. Your Workers’ Compensation lawyer will protect your legal rights and help you obtain evidence to prove that your injury or illness is work-related.nMissed deadlines for filing a claim. There are clear deadlines in place for filing a Workers’ Compensation claim. If you do not file your claim on time, you could be denied the financial benefits that you are entitled to and that will help you recover from your injury. Your Workers’ Compensation lawyer will work closely with you to ensure that your claim is filed well before the deadline passes.
