Missouri State Medical Association Joins Lawsuit Against MultiPlan and Leading Insurance Providers Over Health Care Price-Fixing

Federal antitrust litigation seeks to hold MultiPlan and major insurance companies responsible for alleged coordinated price-fixing scheme leading to under-reimbursement for out-of-network services

Missouri State Medical Association has joined a federal multidistrict litigation (MDL) against MultiPlan (recently rebranded to Claritev) and major insurers, including UnitedHealth, Elevance, Humana, Aetna, and Cigna, alleging they conspired to systematically underpay physicians for reimbursements for out-of-network services, which often fail to even cover operating costs.

Missouri State Medical Association joins the American Medical Association (AMA) and hundreds of physician practices and facilities nationwide in this growing antitrust litigation.

“For many years, physicians in Missouri have been forced to accept increasingly insufficient reimbursements for providing healthcare to out-of-network patients,” said Brian Biggers, MD, Missouri State Medical Association President. “This lawsuit is an important step to ensure that physicians are justly reimbursed for the care they provide and end this alleged illegal collusion that hurts patients.”

This lawsuit, filed in the Northern District Court of Illinois in 2024, seeks to end MultiPlan’s alleged anticompetitive scheme that it has operated since at least 2015 and recoup financial damages for physicians and practices. As of 2024, MultiPlan processes more than 80% of all commercial out-of-network reimbursement claims in the United States.

Physicians who believe they have been harmed by MultiPlan and the insurance companies can obtain a free case evaluation from one of the law firms appointed by the court to lead the non-class claims or contact the firm via email at multiplanlitigation@agg.com.
