BALTIMORE — Charlene Frizzera, CMS COO, will act as administrator of the agency until the Obama administration puts forth its own nominee. Frizzera replaces Kerry N. Weems, who has been CMS acting administrator since 2007.

In other transition news, President Obama has tapped Campaign for Tobacco-Free Kids head William Corr as deputy secretary for the Department of Health and Human Services. Corr was chief counsel to HHS Secretary-Designate Tom Daschle when the former South Dakota senator was Senate minority leader. If both are confirmed, they will lead the administration's effort to reform the nation's nearly $2.3 trillion health care system.
