If you are new to Medicare and have never been paid, you will need to mail in at least one claim on paper and receive payment in order to register for NMP. This needs to be done before you can submit a test file in the Noridian Medicare Portal. In an effort to simplify the NMP submission process, below is a list of items to check when submitting:

• Group and/or Billing NPI is registered on EDISS Connect
• Be sure to select the I will and/or option for the 837 transaction selected in Connect
• Have a software that can build the files that meet the minimum requirements:
  • The file must be an 837P (Professional) or 837I (Institutional) transaction
  • Files being uploaded should not be more than 10 MB.
  • Files sent should be in an ANSI X12 format and contain a file extension of .txt, .edi or .dat
• Once the file has been submitted, a Submission ID will be provided with a message indicating the file was uploaded successfully.
• To view the EDI generated reports, choose the "My Previous Claim Submissions Request" button. Only claim files that were submitted through NMP will have the applicable reports to view. The reports and claim submission files will be available to be viewed for 30 days.

Note: Please allow 4 to 24 hours for the reports to generate and be viewable.
