Recent policy discussions in Illinois have focused on reducing workers’ compensation costs and making the state more attractive to businesses. This study examines medical payments, prices, and utilization in Illinois compared with 16 other states (Arkansas, California, Florida, Georgia, Indiana, Iowa, Louisiana, Massachusetts, Michigan, Minnesota, New Jersey, North Carolina, Pennsylvania, Texas, Virginia, and Wisconsin). The report also examines how these metrics of medical payments have changed over time. We analyzed claims with experience through 2014 for injuries up to and including 2013. In some cases, we have a longer time frame to supply historical context for key metrics. We have also added information from other Workers Compensation Research Institute (WCRI) benchmarking studies to provide a more complete picture of the system in Illinois.
