California hospitals must meet the federal machine-readable file (MRF) requirement under 45 CFR 180.50 — and California layers its own rules on top: California SB 260 strengthens hospital price transparency, requiring payer-specific negotiated rate disclosure and expanding state enforcement beyond the federal baseline. With ~470 hospitals in the state, CMS's 2026 AI-enabled audit ramp means non-compliant files in California are more likely than ever to convert a warning letter into a $5,500/day fine.
California's Office of Statewide Health Planning ties hospital license renewals to transparency compliance — a state mechanism with teeth beyond CMS fines.
Federal baseline: 45 CFR Part 180 still applies to every California hospital regardless of state rules. Missing either track is an exposure.
