Description: The Affordable Care Act (ACA), which became law in March 2010, called for the establishment of a federal health insurance marketplace, and gave states the option to create their own. Minnesota chose to further advance its health care system by building MNsure, a Minnesota-made health insurance marketplace, where Minnesotans can shop, compare and choose health insurance coverage that meets their needs.
