Roughly 100,000 people enrolled in health insurance through Obamacare last month, far short of the administration's goal.
The Health and Human Services Department said 106,185 people have successfully applied for and chosen private insurance through the health care law's new marketplaces. That total is only about 20 percent of the administration's initial enrollment target for October, the first month in which consumers were able to sign up for coverage.
Officials have long acknowledged they would fall short of that target because of the problems surrounding HealthCare.gov, the problem-plagued website that handles enrollment for 36 states.
HealthCare.gov has performed even worse than expected. Fewer than 27,000 people selected a plan through the website, compared with roughly 79,000 who picked a plan through the 15 state-based insurance exchanges. Unofficial estimates leaked earlier this week suggested the federal website had done slightly better.
Another 396,000 people have been approved for Medicaid benefits, according to HHS.
