New healthcare provider organizations methodology

Source

• Centers for Medicare & Medicaid Services: national plan and provider enumeration system (npi registry).

Unit of record

One row per organization, dated by when the authority recorded it, placed by the locality it names.

Update cadence

Weekly. Each page shows the date its data last changed.

Company matching

Records are linked to a company on registration numbers, government identifiers, addresses and domains, never on a similar name alone. Records about individuals are not named on public pages.

Coverage

Known limits

Coverage depends on what each authority publishes and when. Some records cannot be linked to a company with confidence and are shown without one. Values are as declared by the filer.
