Iowa law supports prompt payment of Work Comp benefits so the injured worker will not have to experience any financial difficulty due to the work injury. The majority of Work Comp insurance companies require a written report of the injury as well as some medical confirmation of the Iowa work injury. Iowa law requires weekly Work Comp benefits to be paid to injured workers on the eleventh day of disability. In some situations, if benefits fail to be paid at this time, or are unreasonably late or even denied, then the worker may be entitled to additional benefits. Payments of benefits end when the worker has returned to work, or upon thirty days notice stating the reason for termination and advising the worker of their right to file a claim with the Workers' Compensation Commissioner.
