Provenance of data

General

The ratified convention

The PROVIDER table contains a list of uniquely identified healthcare providers. However, duplicate NPI numbers may occur because the source data might provide the NPI representing the care site rather than the individual provider’s NPI. NPI should not represent a primary key within the PROVIDER table.
