Fairview Health Services will soon no longer be part of the medical provider network for Blue Cross and Blue Shield of Minnesota unless they can resolve a standoff over prices. The current contract expires Aug. 23, and if a new one isn't signed Blue Cross members then would have to pay out-of-network charges at Fairview clinics. Blue Cross is Minnesota's biggest health insurer, with 2.9 million members, while Fairview is the third-biggest hospital and clinic group and owns the University of Minnesota Medical Center.
