Quote:The Obama administration admitted Thursday that it over-reported the number of people who signed up for medical coverage under the President’s signature health care law by double-counting, in its initial reported numbers, hundreds of thousands of people who enrolled in dental insurance plans.

Health and Human Services Secretary Sylvia M. Burwell acknowledged the error on social media after a Bloomberg News report alleged that the administration had included about 400,000 dental plans in numbers it reported for enrollments under the Affordable Care Act.

“The mistake we made is unacceptable,” Burwell said on Twitter. “I will be communicating that clearly throughout the (department).”

A White House spokesman later told the Associated Press that the administration had mistakenly over-reported Obamacare enrollment numbers by about 400,000 by double-counting consumers who had purchased both dental coverage and medical insurance coverage separately through Healthcare.gov and various state insurance marketplaces created under the law.
