A workers' comp claim is best filed as soon as an injury occurs. In some states, there are time limits, such as one month following an incident. After an injury, an employee must notify their employer. The employer must then provide access to the necessary forms and offer guidance. Employees must fill out all forms and return them to the employer who then files them with the insurer. Some states have additional requirements, including assessment by a medical provider. Once the paperwork has been filed, the insurance provider issues a ruling. If the ruling is unfavorable, the employee may choose to appeal the decision with the support of an attorney.
