CEDI Medicare Beneficiary Identifier (MBI) Implementation

National Government Services, Inc. Common Electronic Data Interchange (CEDI) will bring down the CEDI Gateway at 3:00 p.m. ET on Tuesday, December 31, 2019 until no later than 11:59 p.m. ET to implement changes to require the Medicare Beneficiary Identifier (MBI).  During this time, CEDI customers will not be able to connect and exchange transactions with CEDI.  Once the updates have been installed and verified, the CEDI Gateway will be brought back up for CEDI customers to resume exchanging transactions with CEDI.

  • Claims Status Category Code of A7 (acknowledgment rejected for invalid information), a Claims Status Code of 164 (entity‚Äôs contract/member number), and an Entity Code of IL (subscriber)
