An independent reference built from the federal NPPES file published by the Centers for Medicare & Medicaid Services, and the NUCC Health Care Provider Taxonomy. Not affiliated with CMS, NPPES or any provider. An NPI shows that a provider is enumerated; it does not prove that they are licensed or credentialed.
