Jauary 2018 Release Dark Days for the Common Working File Hosts

In anticipation of the January 2018 Release, the CWF Hosts will not process claims beginning Friday, 12/29/2017 through Sunday, 12/31/2017. During this period, which is commonly referred to as "dark days," the CWF Hosts will install the January 2018 Release, complete weekly/monthly/quarterly processing activities, and perform scheduled data center maintenance. Note: On Monday, 1/1/2018 the onlines will be available for HIMR, BDS and the MBI/HICN crosswalk, but no CWF cycles will be run.

These dark days will limit access to information provided by the IVR system and to their self-service portal, NGSConnex. Providers may experience limited or no access to claims, eligibility, claim overlap, patient status, check inquiry, reopening/redetermination status, offset information, and financial claim information.
