CMS' RDS Center will perform system maintenance on the RDS Secure Website on Friday, September 18, 2026, beginning at 9:00 PM ET and concluding Saturday, September 19, 2026, at 10:00 AM ET. The SWS will be available during this time with the following limitations until after system maintenance concludes: Retiree Files uploaded during this time will not appear on the SWS; Weekly Notification Files and Retiree Response Files will not be available for download; and Covered Retiree Lists requested during this time will not be available to view or download. Thank you for your patience. 

Reminder to Mainframe Users: Electronic Transmittal Form Requirements

Reminder: Plan Sponsors and Vendors that submit retiree lists and cost reports through Mainframe are no longer required to complete a new Electronic Transmittal Form (ETF) for each new RDS application. A new ETF is only required if the location where data is sent or received changes.

CMS' RDS Center believes this enhancement improves the efficiency in which Plan Sponsors and Vendors transmit and receive files through Mainframe while also reducing the amount of paperwork.
