In 2012, the New England Journal of Medicine released a study that examined several Medicaid expansions throughout the country. The study found that state expansions of Medicaid reduced mortality by 2,840 deaths when Medicaid was expanded to 500,000 adults. Or, for every 176 additional lives covered by Medicaid, reduced death by 1 individual annually.
Recently, CMS released a report that shows that as of March 2015, Medicaid expansions have increased coverage to an additional 12.2 million people since October 2013.
Scholars have argued to what extent Medicaid improves health. This study showed a more likely link between Medicaid coverage and reduced mortality, especially among people “between the ages of 35 and 64 years, minorities, and those living in poorer areas.” While Medicaid coverage will be different for people across the country, if there is an opportunity to reduce mortality, it will be strongest amongst this population.
