(Las Vegas, NV) — The U.S. Census says about one-quarter of Nevada residents under 65-years-old had no health insurance coverage sometime during 2009. What worries state officials is the cost of implementing the new federal health coverage law. The “Sun” says a state analysis found expanding Medicaid for low-income Nevadans would cost over $600-billion between 2014 and 2019. The federal government is expected to cover a portion of the cost. Nevada and other states are fighting the health care law’s individual mandate in court.
