This SHARE brief, from Urban Institute Senior Fellow Stan Dorn, details findings from an analysis of Louisiana's landmark used of automated Medicaid enrollment via Express Lane Eligibility (ELE), a strategy authorized by the Children's Health Insurance Program Reauthorization Act of 2009 (CHIPRA).  Under this initiative Louisiana automatically enrolled children into Medicaid based on data matches indicating eligibility for the federal Supplemental Nutrition Assistance Program (SNAP).  Dorn and his co-authors analyze the impact of ELE on several outcomes including enrollment, coverage, administrative costs, and administrative efficiency.
