Prescription Drug Event Error Code Listing

On October 3, 2014, CMS announced the closing of the Drug Data Processing System (DDPS) for benefit years 2007 and 2008. The closure will become effective on January 1, 2015. The edit message associated with reject edit code 788 will now read “DDPS no longer accepts PDEs with dates of service before 1/1/2009”. It has also come to CMS’ attention that the language in the Comments/Rationale field was incorrect for edit code 783. The Comments/Rationale field for edit code 783 will now read “Edit was re-established as of 4/24/2011 for all DOS.  Applies when DOS greater than the store closing date plus six months".
