The California Court of Appeal recently ruled in favor of VHS Liquidating Trust in a significant antitrust case against MultiPlan Corporation. The court's decision, filed on September 21, 2026, allows VHS to pursue claims related to alleged price-fixing and other antitrust violations concerning out-of-network medical service reimbursements. This ruling is crucial for healthcare providers and could reshape the reimbursement landscape for out-of-network services.
The case, VHS Liquidating Trust v. MultiPlan Corporation (docket number A171914), centers on VHS, the bankruptcy liquidator for the Verity Health System, which operated several not-for-profit hospitals in California. VHS alleges that MultiPlan, which provides healthcare data and analytics services, conspired with insurers to suppress reimbursement rates for out-of-network medical services, thereby harming healthcare providers like Verity.
The dispute began when VHS filed a lawsuit against MultiPlan in September 2021, claiming that the company engaged in illegal price-fixing practices under California's Cartwright Act. The trial court initially dismissed VHS's claims, ruling that reimbursements for out-of-network services were not subject to price-fixing regulations. VHS appealed this decision, leading to the recent ruling by the California Court of Appeal.
In its ruling, the court reversed the trial court's decision, stating, "We see no basis for exempting this category of payments from the broad reach of the Cartwright Act." The court emphasized that the reimbursement rates set by insurers for out-of-network services are indeed prices that can be fixed or tampered with, which could lead to antitrust liability. This ruling was made by a panel of judges in the California Court of Appeal, although specific names were not provided in the opinion.
The court's decision is significant for several reasons. First, it clarifies that the Cartwright Act applies to the reimbursement rates set by insurers for out-of-network services, thereby allowing healthcare providers to seek legal recourse against practices that may harm their financial viability. The ruling also aligns with federal antitrust principles, reinforcing the notion that insurers' payments to providers are subject to scrutiny under antitrust laws.
This ruling could have far-reaching implications for healthcare providers across California and potentially nationwide. If VHS successfully proves its claims, it could lead to increased reimbursements for out-of-network services, benefiting not only hospitals but also patients who may face unexpected medical bills due to low reimbursement rates. The case may also set a precedent for how antitrust laws apply to the healthcare industry, particularly regarding the relationships between insurers and providers.
Looking ahead, the case may still face further legal challenges. While the California Court of Appeal has allowed VHS's claims to proceed, MultiPlan could potentially seek to appeal this ruling to the California Supreme Court. Additionally, there is a related case pending in federal court in Illinois that involves similar claims against MultiPlan and several insurers, which could influence the outcome of VHS's case.
In conclusion, the California Court of Appeal's decision to allow VHS Liquidating Trust's antitrust claims against MultiPlan to proceed marks a significant development in the ongoing battle over reimbursement rates for out-of-network medical services. The outcome of this case could reshape the financial landscape for healthcare providers and impact how insurers negotiate reimbursement rates in the future.
