  1. Your Role (View "Roles" table at top of page for descriptions)
    • Provider Administrator
    • End User

Step 6: Add Provider/Suppliers
YouTube Video Tutorial
  1. Enter required information
    • Medicare Program (Part A, Part B, DME)
    • Trading Partner ID (Issued by EDI/CEDI)
      • A Trading Partner ID is NOT required for a DME supplier registration
    • National Provider Identifier (NPI)
      • NPIs must be registered as electronic claim submitters.
    • Provider Transaction Access Number (PTAN)
    • TIN or Social Security Number (SSN)

If registering as a Provider Administrator, the following are required:

  • Check Number - Enter check number of one of 50 most recently issued checks by Noridian
    • Part A providers must enter check information issued within last 90 days. Part A check numbers contain "EFT" in front of the check number. Part B check numbers are a series of numbers without "EFT".
  • Check Amount - Enter amount of corresponding check number
Tip Noridian recommends contacting the IVR to obtain recent check information. A remittance advice cannot always guarantee accurate check number and amount information.
  • DME suppliers must indicate what Jurisdiction the check amount and number was issued from - Jurisdiction A (JA) or Jurisdiction D (JD)

If registering as a Vendor, the following are required:

  • Vendor Administrators and Vendor End Users must enter their Vendor Trading Partner ID and the Provider/Supplier Trading Partner ID submitted by the provider.
  • DME Vendor Administrators and Vendor End Users must enter same Trading Partner ID that Provider Administrator entered in both fields
Tip If the incorrect role has been selected in Step 5, use the Back button on the bottom of the screen to return to Step 5 and choose the correct role.

Helpful Reminders:

  • One TIN/NPI/PTAN combination is needed during registration. Additional combinations may be added by going to Manage Account > Provider/Supplier Combinations once registration is complete.
  • Enter group or billing provider combinations only. Do not enter individual provider combinations.
