CMS Administrator Marilyn Tavenner announced Friday she will resign at the end of February, according to The New York Times.
Ms. Tavenner's resignation comes without forewarning; she had not previously indicated plans to step down, according to the report.
Ms. Tavenner was appointed administrator in May 2013 and helped oversee the Patient Protection and Affordable Care Act changes and the tumultuous launch of the HealthCare.gov marketplace. She has worked with CMS since early 2010.
Principal Deputy Administrator Andy Slavitt will take over as the interim administrator.
