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.

What confidence means

Confidence describes identity certainty — how strongly the identifiers and attributes agree that this listing is this official record. High usually means an exact identifier match (CCN/NPI); Medium/Low means we matched on weaker signals (name + location) and need review. Confidence is not a quality score and says nothing about the care a provider delivers.

What it can and cannot prove

Can: establish that a listing corresponds to a specific official record, so official measures are attributed to the right entity.
Cannot: prove anything about quality, conduct, or outcomes. A match only connects identities; the measures themselves are interpreted on each dataset’s methodology page.

Limitations

Identifiers can be missing or reused, names and addresses change, and chains share similar names — so some records won’t link, and a few may need correction. Sensitive datasets (e.g., Open Payments) require an exact identifier match before anything is shown publicly.

Report a data issue

If a provider page shows the wrong official record, please contact us with the listing and what you observed, or a provider can request a correction from its provider dashboard. We re-check the match against the source; we never alter official records.
