A federal antitrust lawsuit against MultiPlan, now known as Claritev, and several major health insurance companies could have significant implications for physicians in Colorado. The suit names UnitedHealth, Elevance (Anthem), Humana, Aetna, Cigna, and various Blue Cross Blue Shield entities as defendants. MultiPlan operates under several other brands familiar to healthcare providers, such as Data iSight, Viant, NCN, ProPricer, and MARS.
The plaintiffs allege that MultiPlan and these insurers coordinated to fix prices and suppress out-of-network payment rates for healthcare services. According to the complaint, the insurers used MultiPlan’s pricing tools to set payments at artificially low levels. This practice may have led to lower reimbursements for physicians and facilities across the country.
Physicians in Colorado may have been affected by these practices without their knowledge. Claims processed through MultiPlan’s systems could result in reduced payments compared to what might be expected in a competitive market. These adjustments may appear on Explanations of Benefits or remittance advice documents; however, MultiPlan’s involvement is not always clearly indicated.
Recent developments in the case include a statement of interest filed by the U.S. Department of Justice in March 2025, which indicates federal concern over the alleged conduct. In June 2025, a federal court denied the defendants’ motion to dismiss the case. As a result, the litigation will proceed into discovery.
These steps suggest that there is substantial merit to the claims and that further investigation is warranted.
Physicians who received out-of-network payments from major insurers over the past decade may be eligible to seek financial damages related to these claims. Providers do not need to wait for a class action decision before pursuing individual recovery; attorneys appointed by the court are leading non-class claims now. A proposed class action is also underway but a decision on whether it will proceed as a class action is not expected until 2027.

Whether through advocacy at the Capitol, regulatory reform, or monitoring high-impact litigation like this, CMS works to ensure physicians have the information and support they need to protect their practices.”
