CPSEPortal maintains a database of NPIs published by the the National Plan & Provider Enumeration System (NPPES). The NPPES publishes updates on a weekly basis and when those updates are published, they are loaded into CPSEPortal.
At times, a user may obtain a new NPI and you wish to add them to the system before that new NPI appears in CPSEPortal.
When that happens, the following screen will appear when trying to add that person.
If you have confirmed that the NPI is correct, go ahead and click the Add Provider Anyway button and the system will let you add the person with that NPI. When that new NPI appears in the update from NPPES, that user will automatically be linked with their NPI.
