Effective June 16, 2017, providers who submit their redetermination and/or reopening requests through the Noridian Medicare Portal (NMP) will now receive their Level 1 Medicare Redetermination Notices (MRNs) via NMP. 

If a redetermination or reopening outcome results in a fully favorable (payable) determination, the remittance advice will provide details. For all other decisions in which providers receive an MRN, the determination letters will now be available through the Appeal Status Inquiry feature in NMP only.

Practices that submit electronic reopening and redetermination requests should ensure that any assigned staff member is registered as an NMP user, as MRNs will no longer be mailed in these cases.

Noridian encourages the submission of electronic reopening and redetermination requests and all supporting documentation (10 mb per file; unlimited number of file submissions per claim) via NMP. This submission method ensures that the requests contain all required information, including the signature on Redetermination requests.
