This is the Noridian Medicare Portal (NMP) User Guide. To use the elements within this guide you must first be logged into the portal.

There are five different roles available for an NMP registration. Prior to registration, companies should discuss, within their facility, who is going to hold each role. Each person may register for one role only. All portal users must be located in the United States.
