Prescription Drug Event (PDE) Processing Hold

CMS will be performing a system enhancement to the Drug Data Processing System (DDPS).  Due to this, Prescription Drug Event (PDE) processing has been placed on a brief hold until the enhancement is completed. Please note that submitters may continue to submit PDE files to the Prescription Drug Front-end System (PDFS) during this time, however return reports may 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
