On February 24, DOJ and the Attorneys General in Minnesota and New York filed a suit to stop the acquisition of Change Healthcare Inc. by UnitedHealth Group Incorporated. The complaint alleges the proposed deal would harm competition in both commercial health insurance markets and the market for a critical technology health insurers use to process claims and reduce costs. The DOJ alleges the proposed $13 billion acquisition would enable the largest U.S. health insurer to use a vast amount of Change’s competitively sensitive information to gain an unfair and harmful competitive advantage in health insurance markets.
