Obamacare bigwig quits

The Obama administration official tasked with implementing the Affordable Care Act and launching its website is stepping down next month.

Marilyn Tavenner has served as the director of the Centers for Medicare and Medicaid Services since 2011, and her tenure has included the initially disastrous rollout of Healthcare.gov in October 2013. She was often the target of pointed criticism on Capitol Hill, including in November of last year after it was disclosed that ACA enrollment figures had been inflated by nearly 400,000 people because those who had signed up for dental plans had been counted twice, according to USA Today.

Tavenner did not explain her reason for leaving in an email to colleagues on Jan. 16. She will be replaced by Andy Slavitt, a former executive at UnitedHealth Group who has worked with the agency on HealthCare.gov’s technical issues.
