The Washington Post said Saturday the error rate was better than the roughly 25 percent rate during the troubled launch of the so-called Obamacare website, but glitches remain.
Julie Bataille, spokeswoman for the Centers for Medicare and Medicaid Services, told reporters Friday three basic technical issues were affecting applications, which are known in the insurance industry as 834 transmissions.
"There is a range of reasons of why it's difficult to categorize and count," Bataille said. "If you look at range of issues of what we're dealing with ... each is a different set of circumstances. We have to very methodically and precisely go through individual transactions at a [granular] level in order to reconcile the information."
The situations include transmissions that do not go through or are duplicated by the computer system. Other transmissions go through, but have errors in them or missing information.
As a result, about 6,700 enrollments in October had to be re-checked with the insurance carrier before approval, The Hill said.
Bataille said Friday about 3.7 million consumers visited HealthCare.gov from midnight Sunday to noon Friday to learn about their insurance options.
She said the site remained stable and experienced no unscheduled downtimes, and the average error rate was 0.77 percent.
