How to read this index

Sourced, dated, free to cite

Specialty classifications come from the CMS NPPES taxonomy — the federal record of how each provider self-classifies. We report that record and its limitations; we do not certify providers or assert facts a public source cannot support. Browse the data catalog, review every registered source, or read the methodology.[1]
