Every number on this site comes from public data:
- Hospital machine-readable files (MRFs) — published by each hospital under the federal Hospital Price Transparency rule (45 CFR §180), effective January 1, 2021.
- CMS Physician Fee Schedule (PFS) — for the Medicare benchmark on physician-administered services.
- CMS Clinical Laboratory Fee Schedule (CLFS) — for lab-test Medicare rates.
- CMS IPPS — DRG relative weights and base rate for inpatient stays.
- CMS Provider of Services / hospital registries — for hospital names, locations and identifiers.
We refresh hospital files periodically; see our methodology for how the data is processed.
