Blue Cross Blue Shield of Michigan and its opponents are continuing their high-profile fight over legislation the health insurer wants approved by the end of the year. Blue Cross said it projects losses of nearly $264 million on its health insurance plans covering individuals in 2009 and that changes in state law are urgently needed to keep the nonprofit on solid financial footing. Critics say the changes long sought by Blue Cross would hurt consumers and give the nonprofit unfair advantages over its for-profit competitors.
