April 2015 Release "Dark" Days for the Common Working File (CWF) Hosts
For the upcoming April 2015 release, there will be two "dark" days on Friday, April 3 and Saturday, April 4, 2015.
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 April 3 will be held one additional day due to a CWF history conversion.
- We anticipate that claims will still be processed within a normal timeframe, and these slight delays will not affect the timeliness of your payments.
- April 3 and 4, 2015 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" day 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.
