Prescription Drug Event (PDE) Processing Hold

CMS will be performing system changes to the Drug Data Processing System (DDPS) beginning this weekend.  Due to this, DDPS will need to suspend PDE processing beginning with Cycle 1 on Saturday, December 8th until Thursday, December 13th.  Please note that submitters may continue to submit PDE files to the Prescription Drug Front-end System (PDFS) during this time, however return reports will be delayed.  A listserv notification will be distributed to the industry once processing resumes.

In the event you have questions, please contact CSSC Operations at 1-877-534-2772 (Option 2) or by email at
