U.S. Health and Human Services Department Secretary Sylvia Burwell on Tuesday afternoon tweeted that more than 60,000 applications had been filed on federally run HealthCare.gov in the first six hours of enrollment.
HealthCare.gov, which serves residents of 39 states, was experiencing some slow-downs in processing customers as a result of that level of interest.
"As has been the case on previous high-volume days, customers can visit HealthCare.gov and view plans but some are periodically experiencing a waiting room before they log in," said HHS spokeswoman Marjorie Connolly.
"Throughout this open-enrollment period, as we have in years past, we'll continuously work to ensure consumers visiting HealthCare.gov have a quick and easy experience signing up for quality, affordable coverage."
Obamacare plans for 2017 have, on average, sharply higher premiums, or monthly enrollment charges, than they do for the current year. The average "benchmark" plan on HealthCare.gov — which is the second-lowest cost silver-level plan sold in a given geographic region — is rising by 25 percent next year. Silver plans, the most popular type of Obamacare plans, cover roughly 70 percent of their customers' health costs.
