CMS Pub. 100-04, ch. 24, § 50.8
Nulls
The null scrubbing of outbound data exiting the Enterprise Data Center (EDC), prior to
its delivery to the Local Data Center (LDC) was initiated with Transmittal 702 Change
Request 6946, Combined Common Edits/Enhancements Module (CCEM) October
Release Update for Test/Production Indicator Activity and Outbound Data Scrubbing.
The scrubbing process will apply to ASC X12 outbound file structures to the EDC (e.g.,
ASC X12 835 and 277 flat files). It will not apply to outbound ASC X12 837 COBC
files.
The Shared System maintainer shall implement a scrubbing process that occurs after the
creating of the outbound file structures at the EDC (e.g., ASC X12 835 and 277 flat files).
Once the flat files have been processed through the EDC’s receipt, control and balancing
jobs they are viewed as ready for transmission to the LDC. At this point in the process
null values are to be replaced with spaces.
