January 2026 Release "Dark Days:"

To install the January 2026 release, the Common Working File (CWF) Host will observe a Gray Day on Wednesday, December 31, and Dark Days on Friday, January 2 – Sunday, January 4.

What this means to you:

  • It's customary for contractors to hold claims for several days following a quarterly release. Claims submitted during this period won't continue to process until the nightly system cycle runs on Tuesday, January 6.
  • We anticipate claims will still process within the normal timeframe and the slight delay won't affect the timeliness of your payments.
  • You can still access beneficiary eligibility information, but it won't update during the dark day period.

Home Health & Hospice providers: You can still submit Notices of Admission (NOAs) and Notices of Election (NOEs). If you feel the dark day period caused a late NOA/NOE submission, you must provide the appropriate supporting documentation with the associated final claim.
