The California Medical Association (CMA) is hosting a free webinar on Wednesday, November 20, 2025 – Navigating the MultiPlan Litigation: What Physician Practices and Facilities Need to Know. The members-only webinar will go over the origins of the litigation, key legal developments, strategies for joining the case, and why now is the time to act.

Background on the Case

CMA, alongside the American Medical Association and hundreds of physician practices nationwide, has joined a sweeping federal multidistrict litigation (MDL No. 3121) against MultiPlan (recently rebranded as Claritev) and major insurers including Aetna, Cigna, UnitedHealth, Elevance, Humana, and Blue Cross Blue Shield. The lawsuit, filed in the Northern District of Illinois, alleges that MultiPlan and the insurers conspired to systematically depress reimbursements for out-of-network services – often below the cost of providing care.

According to the complaints, these payors outsourced rate-setting to MultiPlan, which used proprietary pricing tools to artificially suppress payment rates. By pooling sensitive pricing data and imposing uniform methodologies, the defendants allegedly eliminated market competition, depriving physicians of fair payment while generating profits from administrative fees tied to the underpayments.

The plaintiffs are seeking compensation equal to the difference between actual payments and the fair market value of the services provided. If successful, the case could lead to significant reimbursements for participating providers and drive changes in how out-of-network rates are determined nationwide.

How to Know if You’re Affected

Physicians may not always know whether MultiPlan priced their claims. Clues can often be found in explanations of benefits or remittance advice showing references to “MultiPlan,” “Data iSight,” “Viant,” “NCN,” “ProPricer,” or “MARS.” All such claims—including those negotiated or paid under the No Surprises Act—may be eligible to participate in the MDL. As of 2024, MultiPlan processes more than 80% of all commercial out-of-network reimbursement claims in the United States.

Join us on November 20 for CMA’s members-only webinar, presented by AGG Healthcare Litigation partner Matt Lavin, a member of the Executive Committee for direct-action plaintiffs in the case. Lavin will walk through the litigation, what it means for California physicians, and how practices can evaluate whether they are eligible to participate. Click here to register.
