President Barack Obama nominated Marilyn Tavenner, the second-in-command at the Centers for Medicare & Medicaid Services, to succeed the outgoing Dr. Donald Berwick after he steps down Friday.
Tavenner has been in the second chair at CMS since February 2010, serving as principal deputy administrator and COO. She will keep her current positions but serve as acting administrator during the Congressional confirmation process.
