Appeal for a hearing is what the workers comp denial letter usually informs the injured worker in Wisconsin and it gives the address or telephone number of the State of Wisconsin DWD in Madison. It implies a simple process, but for most workers comp claims it is a complicated, expensive and time consuming legal procedure. First, the experienced attorney will collect the relevant medical records, then obtain the necessary medical opinions on causation and permanent injury if appropriate. Finally, the attorney files the evidence and requests a hearing. In a serious back injury or neck injury claim, this process may take about one year after the injured worker reaches an end of healing or a healing plateau.
