Administrative Data
Provider, demographic, and encounter reference data
The reference data that fills the administrative fields of a message rather than the clinical ones — who the provider is, how they are classified, where care was given, and how demographics are coded.
NPI Registry
Look up US providers and organisations live against the CMS NPI Registry, by name, NPI, or location
Provider Taxonomy
Search the NUCC provider taxonomy — the classification behind PRD and PV1 provider roles
Race and Ethnicity
964 CDCREC codes, the value set behind PID-10 and PID-22
Place of Service
All 51 CMS place-of-service codes used in claims and encounter reporting
NPI lookups query the CMS registry directly, so results are current rather than a snapshot. The other three are served from local reference data and work without leaving the app.
