Judge denies U.S. bid to block UnitedHealth, Change Healthcare deal

A U.S. judge has denied the Justice Department's bid to stop UnitedHealth Group Inc. from buying Change Healthcare Inc., in a blow to the U.S. administration's tougher enforcement of antitrust issues, Reuters reports. The Justice Department had filed a lawsuit in February aimed at stopping the $8-billion acquisition, saying the deal would give the largest U.S. health insurer access to its competitors' data and push up healthcare costs.
