Based on case studies and focus groups, this brief reviews delivery systems and access to care for Medicaid enrollees in Colorado, Connecticut, Kentucky, and Washington as of Spring 2016. The findings provide an on-the-ground view of Medicaid delivery systems and enrollees’ experiences accessing care three years after implementation of the Medicaid expansion. This brief builds on previous reports that examined states’ preparation for implementation prior to the initial ACA open enrollment period and their experiences after completion of the first and second open enrollment periods.
