Saint Francis Blue Cross Blue Shield of Oklahoma said Wednesday that negotiations with Saint Francis Health System had failed and, as a result, Saint Francis will leave the network on July 29th. "After months of negotiation in good faith with Saint Francis Health System, BCBSOK and Saint Francis were unable to reach an agreement that would protect Blue Cross and Blue Shield of Oklahoma members and customers from future cost increases as the hospital system continues to grow and expand," the insurer said in a statement. The split, first reported by KTUL, impacts all Saint Francis hospitals, off-campus locations, and all Laureate and Warren Clinic doctors and health care professionals, according to BCBSOK, which said Wednesday it was in the process of informing 59,000 member households of the situation.
