Fighting Back Against Systematic Underpayment by Insurers and Pricing Intermediaries
Healthcare providers nationwide are taking action against MultiPlan and major insurers for what lawsuits describe as a coordinated scheme to underpay out-of-network claims and suppress fair reimbursement rates. At the center of these allegations is the claim that MultiPlan orchestrated a buyers’ cartel among insurers, enabling them to eliminate competition and collectively drive down reimbursement rates.
If your practice has been underpaid on out-of-network claims, you may be entitled to substantial financial recovery. Our firm is actively evaluating claims.
The MultiPlan MDL consolidates lawsuits filed by healthcare providers across the country alleging that MultiPlan (rebranded as Claritev) and participating insurers:
Rather than competing in a functioning market, insurers allegedly used MultiPlan’s platform to coordinate pricing decisions, an arrangement plaintiffs characterize as a significant antitrust violation.
At its core, this litigation challenges an alleged system designed to:
For many providers, the impact has been severe, with years of reduced payments, lost revenue, and unsustainable reimbursement levels.
This case represents an opportunity not only to recover financial losses but to challenge an alleged system that eliminated competition across the market.
In the 3rd Quarter of 2024 alone, MultiPlan boasted underpayments of $6.2 Billion regarding out-of-network claims.
As of 2026, the MultiPlan litigation is actively progressing through discovery, with the case moving toward potential trial phases or resolution while additional healthcare providers continue to pursue claims. In 2025, the litigation entered a critical stage of evidence development, with plaintiffs obtaining internal insurer communications, pricing methodologies, and reimbursement data, allowing experts to begin quantifying the full scope of financial harm suffered by providers nationwide.
The case reached a major turning point in 2024 when the Court rejected efforts by MultiPlan and insurer defendants to dismiss the lawsuits, allowing key antitrust and related claims to proceed and clearing the way for full discovery. This followed the 2023 consolidation of lawsuits into MDL No. 3121, where federal courts centralized cases from across the country to coordinate litigation and streamline proceedings in the United States District Court for the Northern District of Illinois.
Also in 2023, healthcare providers nationwide began filing lawsuits alleging price-fixing, collusion, and other anticompetitive conduct tied to the use of MultiPlan’s pricing systems. These claims arose after years of mounting concerns. Between 2020 and 2022, MultiPlan’s pricing tools became deeply embedded across major insurers, and providers increasingly experienced consistent, unexplained reductions in out-of-network reimbursement, often with little transparency or justification.
The foundation for these practices dates back to before 2020, when MultiPlan developed and expanded its pricing infrastructure, including tools such as Data iSight and Viant, which insurers integrated into their reimbursement processes, ultimately setting the stage for widespread underpayment practices now being challenged in federal court.

How the Alleged Scheme Worked
According to the lawsuits, MultiPlan and participating insurers operated through a structure that functioned as a buyers’ cartel, allowing insurers to align reimbursement strategies rather than compete.
Allegations include those defendants:
According to providers, the result was a systemic reduction in reimbursement across the country.

The lawsuits allege that MultiPlan and major insurers engaged in a coordinated scheme to suppress out-of-network reimbursement rates, including through conduct described as a buyers’ cartel, in violation of antitrust laws.
A buyers’ cartel occurs when competing purchasers coordinate their behavior rather than compete independently. The lawsuits allege that MultiPlan facilitated this coordination, allowing insurers to collectively suppress reimbursement rates rather than negotiate in a competitive market.
You may have been impacted if your payment records, EOBs, or remittances reference MultiPlan or its pricing tools, or if you consistently received payments significantly lower than expected rates.
Providers may be able to recover the difference between what they were paid and what they should have been paid, along with additional damages under federal antitrust law.
Not necessarily. Many providers participate in the MDL while maintaining individual claims. Legal counsel can evaluate the best strategy based on your circumstances.
Yes. Claims may be subject to statutes of limitation, and delays could impact your ability to recover. Early evaluation is important.
