New User Registration Verification - Effective April 24, 2026

Users registering for a new user account on the Noridian Medicare Portal (NMP) will now be required to complete an NPI/PTAN verification prior to starting the registration process. This verification is to ensure that the NPI/PTAN being used to register is active in the Medicare Claims Processing System. If the NPI/PTAN is not active, users will need to work with their Provider Enrollment departments for their respective jurisdictions. Once the NPI/PTAN is active, users can then proceed with the registration process.
