States received funds from the federal government to set up health insurance exchanges and run them for the first year, but exchanges are supposed to be self-supporting next year. A surcharge on exchange-sold plans was intended to fund the exchanges, but lower-than-projected enrollment could pose problems in some states. Unspent federal funds are being saved in some states, while others are asking for extended federal funding, considering raising surcharges or cutting staff.
