Tenet Healthcare Corp. has signed a multiple-year agreement with Blue Cross Blue Shield of Illinois, but two of Tenet's hospitals in the St. Louis area are still struggling to renew their contracts with WellPoint health plans in Missouri. Under a new contract, Blue Cross Blue Shield of Illinois members will have access beginning March 1 to health services at St. Louis University Hospital and Des Peres Hospital, which are both owned by Dallas-based Tenet.
