MSMA Joins MultiPlan Antirust Litigation as Plaintiff

In July, the Missouri State Medical Association joined the MultiPlan Antitrust Litigation as a plaintiff. This is a federal antitrust action against MultiPlan, a healthcare data firm, and leading health insurance companies, including UnitedHealth, Anthem, and Cigna.

Plaintiffs, including the Missouri State Medical Association and the American Medical Association, claim these companies participated in a coordinated price-fixing conspiracy to generate billions in profits for MultiPlan and insurance providers by forcing physicians to accept increasingly low reimbursements for out-of-network services. Plaintiffs seek to end this illegal conduct as well as recoup financial damages for providers who were harmed by this conduct.  

The lawsuits against MultiPlan have been consolidated into a multi-district litigation filed in the Northern District of Illinois before Judge Matthew Kennelly. In March 2025, the Department of Justice filed a statement of interest in the litigation, and in June 2025, Judge Kennelly denied the defendant’s motion to dismiss, allowing the case to proceed to discovery.

The Missouri State Medical Association will keep you updated as the case progresses.

What are the allegations?

• Since 2015, MultiPlan has forced physicians to accept increasingly low payments for out-of-network services, which often do not cover providers’ operating costs.
• Insurance companies like UnitedHealth, Anthem, and Cigna provided MultiPlan with competitively sensitive, confidential information on pricing and reimbursement rates that they could not have otherwise legally shared with each other.
• MultiPlan then used this data in its proprietary algorithm to develop and set substandard reimbursement rates to physicians for out-of-network healthcare services. 
• MultiPlan left providers with little room to negotiate its offered reimbursement rates and requires that physicians who accept reimbursement not pursue additional balances owed by patients.

What does this mean for members?

• The Missouri State Medical Association joining the lawsuit does not make our members individual plaintiffs.
• Your practice may also be entitled to financial damages against Multiplan and other insurance companies.
