This report can help policymakers and other stakeholders identify current cost drivers and emerging trends in payments, prices, and utilization of medical services among nonhospital and hospital providers in the Illinois workers’ compensation system. It also shows how medical payments per claim and their cost components in Illinois compared with 17 other states.

Claims with experience through March 2019 for injuries up to and including 2018 were analyzed. In some cases, a longer time frame was used to supply historical context for key metrics. Information from other WCRI studies was added to provide a more complete picture of the system in Illinois.
