Lawyers for Northside Hospital won a crucial victory with a ruling blocking Anthem Blue Cross Blue Shield from canceling contracts for in network insurance coverage.

Fulton County Superior Court Judge Rachelle Carnesale heard arguments Wednesday and issued orders late Friday extending temporary injunction orders issued a month ago that would have expired Monday. The orders prevent the insurance company from terminating contracts with Northside’s five hospitals and all its medical practice groups until at least April 15. The judge also denied the insurance company’s motion to dissolve the injunction and request to remove the dispute to private arbitration.
