Attention Providers, did you know that when you went on line and obtained an NPI number that you were expected to keep that user name and password in a safe place because as you move through your life and times you are expected to update that information?  If you do not know your user name and password it would be prudent for you to call 800-465-3203 and obtain your user name and password.  Your information in NPI must match your information with Medicare.
