}What it does
- Resolve an NPI to a name, credentials, specialties and practice locations
- Send the NPI system you already use. All the common forms are accepted
- Follow a practitioner to their roles, and a role to its organisation and locations
- Standard FHIR responses, passed through as the directory publishes them
- An empty result means the provider is not in the directory, never that the lookup failed
- Free in production during the community preview
Built on
FHIR R4CMS National Directory
You already hold NPIs. This resolves each one to the practitioner behind it, along with the organisations, specialties and practice locations they work under, backed by the CMS National Directory and served as standard FHIR. Searching by name or specialty is a larger surface and comes later.
