As has been reported, the Michigan State Medical Society (MSMS) is a plaintiff in the In re MultiPlan Health Insurance Provider Litigation, a federal antitrust case alleging that MultiPlan and major health insurers colluded to suppress out-of-network reimbursement rates paid to physicians and other providers and is seeking an immediate end to their anti-competitive conduct.
At the April 9, 2026, case management conference, with the presiding judge, the parties discussed the information the defendants must share as part of discovery, including MultiPlan’s source code and cell phone records of communications between defendants.
The case is now in discovery and the court has selected the 36 bellwether plaintiffs whose cases are being worked up for trial.
Any MSMS member that still wants to file a case still can do so. Physicians are encouraged to reach out to an attorney if they believe they have been impacted by MultiPlan's practices.
