Sen Herb Kohl (D, Wis), chairman of the Senate Special Committee on Aging, wants to know if CVS Caremark Corp is responsibly administering drug benefits as required by the Medicare Part D prescription drug program.
CVS Caremark was formed in 2007 through the merger of CVS, the largest retail pharmacy chain in the United States, with Caremark Rx Inc, one of the nation's largest pharmacy benefit managers. The new company's benefit services include integrating network pharmacy claims processing, benefit design consultation, drug use review, and formulary management.
