Common Working File (CWF) Dark Day for Annual History Archive
On Saturday, August 3, 2019, the CWF Hosts will be conducting a history archive. Due to the anticipated duration of this activity and to ensure the completion of the weekly processing and scheduled data center maintenance, Saturday, August 3, 2019, will be a Dark Day at all CWF Host sites.
- During the "dark day", August 3, 2019, the CWF eligibility systems, ELGA/ELGH and HIQA/HIQH will not be available.
While the CWF Dark Days will impact your access to the CWF eligibility systems , it will not affect your ability to access beneficiary eligibility information through myCGS. In addition, the Interactive Voice Response (IVR) will be available. Medicare Beneficiary Identifier (MBI)/Health Insurance Claim (HIC) Crosswalk information will also be available. For more information about myCGS, refer to the myCGS User Manual. - There will be no claims processing delays. All files received from the Host sites will be completed prior to the start of the history archive.
