In 2008, Oregon was given permission by the Centers for Medicare and Medicaid Services (CMS) to expand the State’s Medicaid program (Oregon Health Plan Standard) by lottery (Allen, et al. 2010). This allowed for a randomized control study focused on the effect of Medicaid coverage on various factors. The Oregon Health Insurance Experiment (OHIE) was conducted to capitalize on this rare event (Allen, et al. 2010, Finkelstein, et al. 2012, Taubman, et al. 2014)
