What the law required
Under 45 CFR § 180, since January 1, 2021 every U.S. hospital must publish a single machine-readable file (MRF) containing standard charges, payer-specific negotiated rates, discounted cash prices, and de-identified min/max negotiated charges. The file must be free, public, and easily accessible without registration, authentication, or PII.
Mark Cuban, in launching Cost Plus Drugs, has spent two years pushing for exactly this kind of price transparency. The law's already on the books. What's missing is the database.
This is that database. Every CMS-required hospital, cross-referenced with the live MRF URL (where it exists) and the CMS enforcement record (where the hospital failed to comply).
