What is a Cause and Treatment (CT) Code and how do I apply it to the entry?
The purpose of the Cause and Treatment (CT) Code is to provide users with information regarding the reason for the exclusion. The Cause provides the authority by which the action was taken and the Treatment provides information on the procedure(s) to apply to the action. Users should review the record’s CT Code(s) to determine the conditions of the exclusion. If you are unable to determine the extent of the exclusion, contact the federal agency responsible for the exclusion. Checking the CT Code is crucial because some CT Codes only apply to a limited number of agencies or provide a specific narrow impact of the listing.
