This 20th edition of CompScope™ Medical Benchmarks for Illinois can help policymakers and other stakeholders in the workers’ compensation system identify current cost drivers and emerging trends in payments, prices, and utilization of medical services among nonhospital and hospital providers. The report also examines how these metrics of medical payments in Illinois compared with 17 other states.

We analyzed claims with experience through March 2018 for injuries up to and including 2017. In some cases, we used a longer time frame to supply historical context for key metrics. We have also added information from other Workers Compensation Research Institute (WCRI) studies to provide a more complete picture of the system in Illinois.
