Many of the provisions to expand health coverage in the Affordable Care Act must be implemented by the states. With support from the Robert Wood Johnson Foundation, the Urban Institute is undertaking a comprehensive monitoring and tracking project to examine the implementation and effects of the ACA in ten of the states: Alabama, Colorado, Maryland, Michigan, Minnesota, New Mexico, New York, Oregon, Rhode Island and Virginia. This first report is a case study analysis of Oregons efforts to advance health care reform. Derived from a site visit and extensive interviews with state officials and state stakeholders, it documents Oregon's considerable progress in establishing an exchange, implementing insurance reforms, and preparing for an expansion of Medicaid, all within a challenging fiscal environment.
