About 1.6 million people have selected a health plan through the federally-facilitated Health Insurance Marketplace since the start of open enrollment Nov. 1, the Centers for Medicare & Medicaid Services announced today. Two-thirds of the plan selections were by 2015 enrollees who were renewing coverage or selecting a new plan for 2016; the rest did not have current Marketplace coverage. Open enrollment runs through Jan. 31 for coverage beginning in 2016.
