Reason for Notice: Waystar would like to remind Medicare providers of the upcoming CMS dark days. CMS will observe a "Grey Day" on Wednesday, July 1, and will be unavailable starting Thursday, July 2, 2026 through Sunday, July 5, 2026. The Dark Days are scheduled to accommodate the July 2026 Release.
Starting as early as Wednesday, July 1, 2026, providers may experience disconnects and limited availability while working in DDE/FISS (Medicare DDE) when accessing the Common Working File for claim status. The outage will result in claim and processing delays for the following services:

Please note delays will occur throughout the week of July 6th as we process any pending submissions for claims and claim batches submitted during the dark days.
