As the fight between the state's largest health insurer and a group of hospitals heats up, Horizon Blue Cross Blue Shield of New Jersey has sued two hospitals. The insurance giant claims public comments by Holy Name Medical Center and The Valley hospital in Ridgewood imply coverage by its new OMNIA policies is somehow deficient or dangerous. "Holy Name Medical Center and The Valley hospital have run a false and misleading ad campaign claiming, among other things, that our company 'couldn't care less' about babies," Horizon spokesman Tom Vincz said Saturday.
