Federal health officials on Wednesday unveiled what they described as a cleaner website and a more logical sign-up process for insurance under the health-care law as they prepared for the next open enrollment period, which begins Nov. 15.

When the first year of open enrollment began last fall, Healthcare.gov had severe technical problems and frequently crashed, resulting in frustration for millions of people trying to sign up for health plans offered in the new online marketplaces created by the Affordable Care Act.

Officials said Wednesday that the enrollment process has been streamlined, and that new customers may face as few as 16 steps — compared to as many as 76 last year.

“Consumers want a faster experience,” said Andy Slavitt, principal deputy administrator of the Centers for Medicare and Medicaid Services, the agency in the Department of Health and Human Services that oversees the website. “They want a more intuitive experience, not to input the same information over and over. And they want mobile.”

In preparation for the next open-enrollment period, the health officials told reporters, they have spent more than five weeks testing the enrollment process. Last year, they said, they spent 10 days testing it. But they said they have only done one day of end-to-end testing so far.

Kevin Counihan, chief executive of HealthCare.gov — a position created by the White House and filled less than two months ago — said that “we want simplicity . . . That’s clearly important.”

“Kevin and I went through, step-by-step, all the iterations of the re-enrollment process,” Slavitt said. “There will be a number of options for people. We don’t think the technology will be a problem.” He and Counihan said they believed they’ve solved most of the glitches in the old system, though they refused to put a number on their level of confidence in the new one.

Both, however, conceded, that a lot is riding on this second chance to get it right. “We feel our own credibility is important,” said Slavitt.
