Update: ICN Assignments Enhancement

On November 6, 2018, CMS announced an enhancement in the processing of Encounter Data files, specifically those received on Saturday or Sunday.  Currently, the Combined Common Edit Module assigns Interchange Control Numbers (ICN) with the following Monday’s date for accepted encounters when encounter files are processed during the weekend.

CMS is targeting the implementation of the new enhancement on Saturday, December 1, 2018.  ICNs will be assigned to accepted encounters with the actual date the files processed. CMS believes this is a benefit to the industry and allows CMS to target files to know when they were actually processed by the Front-End.  Please note that assigning ICNs with weekend dates will not impact the formatting or processing of data.
