Due to extraordinary demand, the Obama administration has extended the Obamacare signup deadline by four days – from December 15 to midnight on Monday December 19. December 19 is the last day to buy coverage that goes into effect on January 1, The Hill reports.
39 states, including Arizona, use Healthcare.gov as their insurance marketplace and therefore received the extension.

The federal marketplace will remain open until January 31 for existing customers to shop and adjust plans.
