An Update on Federal Antitrust Litigation Against MultiPlan, Major Insurers

June 12, 2026

Lawsuit Over Price-fixing in Healthcare Progresses During Discovery

The Arizona Medical Association 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. ArMA is seeking an immediate end to this anti-competitive conduct.

At the May 15 case management conference, the parties discussed with Judge Kennelly the ongoing exchange of evidence from the defendants, including disputes over access to the source code for MultiPlan's algorithms and cell phone records of communications between defendants. The court resolved several of those disputes, approved a 60-day extension to the case schedule, and allowed plaintiffs to update their complaints to add new defendants as the case continues to develop.

The case remains in active discovery, with the 36 bellwether plaintiffs continuing to have their cases worked up for trial. However, any member who wants to file a case still can do so.


Members of the Arizona Medical Association interested in joining the lawsuit as litigants are eligible for discounted contingency fees. If you believe you've been impacted by MultiPlan's practices, you are encouraged to reach out to an attorney.
