MultiPlan Anti-Trust Lawsuit: The Latest Updates for Arizona Physicians

July 9, 2026

An Update on Federal Litigation to End Healthcare Price-fixing

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 clinicians. ArMA is seeking an immediate end to this anti-competitive conduct.


Judge Denies Defendants' "Unclean Hands" Defense 

On June 24, Judge Kennelly denied the defendants’ motion to amend their pleadings to assert an “unclean hands” defense. The defendants sought to allege that improper billing practices by the plaintiffs inflated the reimbursement amounts they bill to the payers, and that the plaintiffs are barred from bringing antitrust claims as a result. Judge Kennelly rejected the defendants’ request, ruling that defenses like “unclean hands” can’t be used to hinder enforcement of federal antitrust law.


Plaintiffs Name Additional Co-conspirators 

At the June 26 case management conference, Judge Kennelly granted a motion by several bellwether plaintiffs to name additional alleged co-conspirators as defendants. The parties and Judge Kennelly also discussed the ongoing exchange of evidence from the defendants and scheduling orders for upcoming deadlines, source code production, and trial dates.


How to Get Involved

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.
