This annual study compares prices paid for medical professional services across 36 states from 2008 to 2024. It focuses on services commonly billed by physicians, physical therapists, and chiropractors, including evaluation and management, physical medicine, surgery, major and minor radiology, neurological testing, pain management injections, and emergency care.

Unlike other indices measuring prices of all medical professional services provided to the general population, this index is a more relevant benchmark of medical inflation in workers’ compensation as it focuses on those services commonly provided to workers with injuries. Since workers’ compensation price regulations are set at the state level, this study provides a state-level price index to help policymakers and stakeholders conduct meaningful comparisons of prices paid across states and to monitor price trends in relation to changes in fee schedules.

This edition covers 36 states that represent 88 percent of the workers’ compensation benefits paid in the United States. These states are Alabama, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, and Wisconsin.
