Affiliation comes from the CMS Doctors and Clinicians Facility Affiliation file, hospital rows only; name, address and type from the CMS Hospital General Information file. CMS does not publish an end-of-year archive of the affiliation file, so the current snapshot is applied to the latest data year. A clinician listed with several hospitals or groups appears on each of their pages. How hospital pages are built
