Antitrust in Michigan

The cornerstone of health information is to share and exchange data among providers, health plans, and other entities, in order to raise quality and lower health care costs.  Doing so raises antitrust concerns about what is or is not permissible under federal antitrust laws.1  Antitrust law governs the sharing of information across integrated and nonintegrated entities, and whether such activities restrain trade.2

The state of Michigan has passed the Michigan Antitrust Reform Act, which prohibits persons from contracting, combining, or conspiring to restrain or monopolize trade.  However, the law allows an exemption for certain cost reducing actions by health maintenance organizations, health insurers, or health care corporations.3
