# Update NPI and participation date at a location-network

`PUT /practitioners/{practitionerId}/locations/{locationId}/networks/{networkId}/npi-par-date`

Updates only the NPI and/or the Location NPI Participation Date (`networkPractitionerEffectiveDate`) for a practitioner at a specific location-network; all other fields on the location-network assignment are preserved. Use this for targeted updates to NPI or participation date without overwriting other location-network attributes — NPI is a location-network attribute and cannot be edited at the practitioner-location level alone. Pass `null` for `npi` or `npiParticipationDate` to leave those values unchanged. `{practitionerId}` is the `certifyPractitionerId`, and the practitioner must already be associated with the specified location and network.
