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.

The study also examines how these metrics of medical payments in Illinois compared with 17 other states (Arkansas, California, Florida, Georgia, Indiana, Iowa, Louisiana, Massachusetts, Michigan, Minnesota, New Jersey, North Carolina, Pennsylvania, Tennessee, Texas, Virginia, and Wisconsin) and how key metrics have changed from 2011 to 2016. In some cases, a longer time frame was used to supply historical context for key metrics.

Claims with experience through 2017 for injuries up to and including 2016 were analyzed. Information from other WCRI studies was added to provide a more complete picture of the system.
