The NC Council for Health Care Coverage worked Friday to put the final touches on a set of principles that it hopes will guide legislators and the Cooper administration toward getting health insurance for more North Carolinians. The large group of lawmakers, employers, insurers and others have met under the auspices of the Duke-Margolis Center for Health Policy since last month to come up with goals for expanded health insurance coverage. Gov. Roy Cooper, a Democrat, created the bipartisan group. He pushed for Medicaid expansion in his first term as the way to get more adults insured. Opponents in the Republican-controlled legislature have said they worry about costs to the state. Medicaid expansion has never come to a vote. The federal government pays 90% of Medicaid expansion costs.
