Nevada’s health care system has undergone a fundamental transformation in the five years since the expansion of Medicaid in 2014. In 2012, nearly 30 percent of Nevadans were uninsured—almost 600,000 individuals. Less than a decade later the state has cut its uninsured rate in half and doubled the size of its Medicaid program. Despite this laudable progress, challenges persist: the state has the highest uninsured rate of any Medicaid expansion state and an estimated 400,000 Nevadans remain without insurance, including nearly 150,000 that are presumed Medicaid eligible but unenrolled.
