As of Dec. 4, a total of 17 states and the District of Columbia had indicated that they will establish the state-based insurance exchanges mandated by the Affordable Care Act, according to the Kaiser Family Foundation.
California and New York are the largest states to commit to creating their own exchanges, but Texas and Ohio are among the 18 states that have indicated their intention to default to federally facilitated exchanges. Five states, including Illinois and Michigan, are planning to partner with the federal government to operate their exchanges; 10 states, Florida and Pennsylvania among them, are still undecided, Kaiser reported.
