The dispute started after Orlando Rodriguez, a mechanic, suffered significant head and brain injuries at work in 2016. His employer’s insurer, Procentury Insurance Company, administered by Illinois Midwest Insurance Agency, accepted the injury as work-related. Beginning in September 2018, Rodriguez’s doctor, Dr. Yong Lee, requested home health care services for Rodriguez in six-week increments. Illinois Midwest approved several requests, sometimes after sending them to utilization review, where a medical professional determines if treatment is medically necessary.
