FTC Sends Price Transparency Warnings to 24 Largest US Health Systems
The FTC told two dozen major health systems that inaccurate or stale CMS Hospital Price Transparency filings may violate Section 5 of the FTC Act, signalling a federal hook that does not depend on CMS enforcement.
On October 5, 2026, FTC Chairman Andrew Ferguson sent warning letters to twenty-four of the largest US health systems, reminding them that Section 5 of the FTC Act requires timely, accurate and transparent compliance with CMS Hospital Price Transparency obligations. The campaign signals that prices that are inaccurate, stale, or inconsistent across a system could be characterised as deceptive conduct — a theory the FTC has not previously pressed in this area with any visible success, and one that operates whether or not CMS has already imposed a penalty. Large systems should note that a warning letter is typically a precursor to a complaint, investigation or civil penalty demand, and that Section 5 reaches conduct CMS does not police. For counsel, the immediate questions are how price files are generated, by whom, and who attests to their accuracy. Worth watching: whether any named system responds publicly, whether the FTC brings a first enforcement action on this theory, and how systems reconcile state all-payer transparency statutes that may impose stricter or different standards than the federal rule. Only a single summary of the letters is available; their specific claims and cited violations are not yet verified.
