In re MultiPlan: the dark side of transparency

Is there a dark side to transparency?

A federal judge just greenlit one of the most consequential healthcare antitrust cases in years: In re MultiPlan Health Ins. Provider Litigation.

The basics:

Case: Full case: In re MultiPlan Health Ins. Provider Litig., 2025 U.S. Dist. LEXIS 104989

Court: U.S. District Court, Northern District of Illinois

The allegations:

Plaintiffs (doctors and provider groups) allege that MultiPlan and nearly every major insurer (Aetna, Cigna, UnitedHealth, Blues plans, and others) used MultiPlan’s Data iSight tool to fix out-of-network reimbursement rates. The claim is that this wasn’t just cost containment—it was collusion dressed up as data.

Yesterday, the court denied motions to dismiss the federal and state antitrust and consumer protection claims, allowing the case to move forward. Only the unjust enrichment claims were tossed.

Is there a dark underbelly of “transparency” as a cover for collusion?

Here’s the theory of the case:

• When payors all use the same vendor to access “market rates,” they create a shared pricing reference.

• When that vendor (like MultiPlan) offers a black-box algorithm that standardizes reimbursements, it flattens competition.

• When pricing becomes too consistent, it stops reflecting a real market—and starts looking like quiet coordination.

You don’t need a backroom deal if everyone is aligning through the same platform.

In antitrust law, that’s information sharing collusion. And in healthcare, it’s happening behind the curtain of so-called “data-driven decision making.”

If this theory seems out there, there’s another analogous case working through the system on rent fixing through a platform landlords could subscribe to. The first settlement in that case (which is not an admission) came out this week. https://lnkd.in/e9WeFJQK

What could the implications of public price data mean? I’m still very much pro-transparency, but we ought to ensure we don’t get too much “price compression.”
