Prices on Florida's ObamaCare insurance exchange will rise by an average of 13.2 percent next year, with at least one health plan increasing rates by an average of 23 percent. The changes, published Monday by state regulators, reveal an uptick in prices on the marketplaces but not the dramatic surge predicted by Republicans and some insurance officials. On average, eight plans on the Florida exchange will increase prices 11 percent to 23 percent while three will cut rates by 5 percent to 12 percent.
