January 2017 Release "Dark" Days for the Common Working File (CWF) Hosts

To accommodate the anticipated duration of the January 2017 release, and to ensure the completion of weekly/monthly/quarterly processing, there will be a period, referred to as “dark days,” when the Common Working File (CWF) will not process claims.  This period begins on Friday, December 30 through Monday, January 2, 2017.

What this means to you:

  • It is customary for contractors to hold claims for several days following a quarterly release.  Claims that are submitted prior to the release that would have been processed through the Common Working File (CWF) on Thursday, December 29 and Friday December 30, 2016, will be held until the CGS nightly system cycle, Monday, January 3, 2017.
  • We anticipate that claims will still be processed within a normal timeframe, and these slight delays will not affect the timeliness of your payments.
  • December 30, 2016 through Monday, January 2, 2017, will be “dark days.” This means that CWF transactions, deductible queries, etc., will not be available (this includes ELGA and ELGH for Part A providers).

While the CWF Dark Days will impact your access to ELGA and ELGH, they will not affect your ability to access beneficiary eligibility information through myCGS. In addition, the Interactive Voice Response (IVR) will be available.
