Background
VHS Liquidating Trust, acting for the bankrupt Verity Health hospital system, sued MultiPlan and related companies under California’s Cartwright Act. MultiPlan supplies insurers and other payors with data and algorithms that recommend how much to reimburse medical providers for out-of-network care. VHS alleged that competing insurers used MultiPlan as a common pricing mechanism to suppress payments below competitive levels.
The San Francisco Superior Court sustained a demurrer, California’s procedure for testing whether a complaint states a viable claim, without permission to amend. It reasoned that an insurer’s out-of-network reimbursement is not a price capable of being fixed under antitrust law because the provider did not agree to that amount in advance. VHS appealed from the resulting dismissal.
The Court’s Holding
The First District reversed. The Cartwright Act broadly protects competitive pricing, and nothing in its text or purpose exempts the amount paid for out-of-network healthcare services. A price does not stop being a price merely because the seller did not negotiate or accept it before performing. The complaint alleged a market in which insurers purchase healthcare services and collectively influence what providers receive for them.
The court also explained that the claim would not fail even under federal antitrust principles, which generally impose more limits than California law. Allegations that horizontal competitors use a shared intermediary or algorithm to coordinate reimbursement rates can describe concerted price tampering rather than independent unilateral decisions. The decision does not establish that MultiPlan actually conspired or that VHS will ultimately prevail; it holds only that the trial court could not dismiss the entire action on the categorical premise that these reimbursements are beyond antitrust scrutiny.
Other arguments raised in the demurrer were neither decided below nor briefed on appeal. The Court of Appeal remanded so the trial court can address those issues first.
Key Takeaways
- Out-of-network reimbursement amounts are prices for purposes of California’s Cartwright Act and are not categorically immune from price-fixing claims.
- A shared pricing algorithm or repricing service can support an allegation of coordinated conduct when competing payors allegedly use it to suppress provider payments.
- The absence of a pre-service agreement between provider and insurer does not eliminate the economic exchange or place the payment outside antitrust law.
- The ruling arose at the pleading stage; defendants remain free to contest conspiracy, market definition, injury, standing, and other issues on remand.
Why It Matters
Healthcare providers challenging algorithm-assisted reimbursement practices now have a published California decision rejecting a threshold defense that could have foreclosed such suits altogether. Insurers, third-party administrators, and pricing vendors should expect courts to examine how reimbursement recommendations are produced, shared, and adopted rather than treating out-of-network payments as uniquely exempt.
The opinion also matters beyond healthcare. It reinforces that California antitrust law focuses on competitive economic reality, including coordination conducted through data platforms or common intermediaries, and may reach conduct even where federal doctrine is narrower.
