Michigan Attorney General Issues Lawsuit Against Blue Cross Blue Shield of Michigan
Update: Oct 6-19, 2026
Michigan Attorney General Dana Nessel recently announced a federal lawsuit against insurer Blue Cross Blue Shield of Michigan (BCBSM). The suit accuses BCBSM of violating antitrust laws in order to monopolize as Michigan’s largest health insurance carrier.
According to Nessel, BCBSM controls 65% of the Michigan health insurance market and 79% of the Preferred Provider Organization market. Nessel argued that Blue Cross’s dominance was caused by anti-competitive agreements that restricted competition and allowed the insurer to drive provider reimbursement rates down, forcing some providers to cut services, close facilities, or leave Michigan. She also claimed that the practices used by BCBSM has resulted in millions of consumers paying inflated prices for their health insurance and medical coverage.
The lawsuit will be filed in the U.S. District Court for the Eastern District of Michigan. Nessel will leave office in January, meaning her yet-to-be-elected successor, Democrat Eli Savit or Republican Doug Lloyd, will choose to either continue or drop the lawsuit.
