Outage for October 2026 Quarterly Release Implementation

The Common Electronic Data Interchange (CEDI) will bring down the CEDI Gateway and CEDI Claims Portal at 3:00 p.m. ET on Friday, October 2, 2026 until no later than 11:59 p.m. ET to implement updates for the October 2026 Quarterly Release. During this time, CEDI customers will not be able to connect and exchange transactions with CEDI. This will allow CEDI to process all inbound files received through 3:00 p.m. ET on October 2, 2026. Once the October 2026 effective updates have been installed and verified, the CEDI Gateway and CEDI Claims Portal will be brought back up for CEDI customers to resume exchanging transactions with CEDI.
