Less visibility that they also named an acting administrator for CMS, as Seema Verma departed. The acting administrator is Liz Richter, who has been deputy director for the Center for Medicare over a decade, since 2007. She has served at CMS since 1990 in roles of progressive seniority.
See an open access article at Healthcare Finance News here. In the short term, there might be decisions as to whether to keep or deep-six some last-minute Trump era rules, before a permanent Biden administrator can be named.
I recall interviewing with Ms. Richter and the Chief Medical officer for the position of Head of the CMS Coverage Group around 2010.
