Michigan Attorney General files federal antitrust lawsuit against Blue Cross Blue Shield of Michigan
Michigan Attorney General Dana Nessel filed a federal antitrust lawsuit on Thursday in the U.S. District Court for the Eastern District of Michigan against Blue Cross Blue Shield of Michigan, accusing the state's largest health insurer of running an illegal monopoly. The complaint alleges the insurer controls 65% of Michigan's health insurance market and 79% of its PPO market, that it and the wider national network of Blue plans agreed to divide customers and territories, restrict product offerings and eliminate competition (dubbed the 'Blue Conspiracy'), and that it used its market power to push provider reimbursement near the lowest in the nation. The suit includes eight counts under the federal Sherman Act, the Michigan Antitrust Reform Act, public nuisance and unjust enrichment, and seeks a permanent injunction, damages, disgorgement and civil penalties. Blue Cross Blue Shield of Michigan says it fundamentally disagrees with the attorney general's characterization of the market and had not yet been served with the lawsuit; none of the allegations have been proven in court.
