Five million people have now signed up for health insurance on the state and federal online exchanges, the Obama administration said Monday — a number that suggests a big-last minute surge to get coverage.

The new figures suggest a final push by the White House to get people to enroll is working. The deadline to get signed up for 2014 is March 31, just two weeks away. As of March 1, the Health and Human Services Department said 4.2 million people had signed up.

“Fernando Valdez and Denise Schroeder were part of a weekend wave of consumers signing up for new coverage and bringing enrollment nationwide to more than 5 million through the federal and state-based marketplaces since October 1st,” Marilyn Tavenner, head of the Centers for Medicare and Medicaid Services, wrote in a blog post.
