CMS Provider Data — Methodology

Mon, 01 Jan 0001 00:00:00 +0000

Facility-level fields (overall/health/staffing/quality star ratings, certified beds, residents, ownership type, staffing hours) come from the CMS Care Compare “Provider Information” dataset, published by the Centers for Medicare & Medicaid Services (U.S. Government public domain).

What it is: point-in-time, facility-level public measures for Medicare/Medicaid-certified nursing homes.
What it is not: a guarantee of current quality, and not medical advice. Ratings can change and may lag recent inspections.
Freshness: each module shows the import date and data period. We refresh on a schedule (see admin → Data sources).
No patient data: we store only facility-level public fields — never symptoms, diagnoses, medications, member IDs, or patient records.

Questions to ask a facility: current staffing levels, recent inspection results, ownership, and how they’ve addressed any past deficiencies.

Entity Matching — Methodology

Official datasets identify facilities by codes like the CCN (CMS Certification Number) and NPI. To show a facility’s official data on its page, we must confidently match our listing to the right official record.

How we match: by identifier (CCN/NPI) when available, otherwise by name + city + state + ZIP/phone.
Confidence + method: every match stores a match method and a confidence score, shown on the page as High / Medium / Low.
Human review: low-confidence matches are not shown publicly until an admin reviews and approves them. This prevents attaching the wrong facility’s data to a listing.
You’ll always see the source. Matched modules link to the official source and this methodology.
