CDISC Controlled Terminology codelists are either extensible or nonextensible. For extensible codelists, new terms (those not already listed as either a CDISC Submission Value, a CDISC Synonym, or an NCI Preferred Term) may be defined and used with the TIG. Terms in nonextensible codelists must be used as-is; new terms cannot be added or used. When extending a codelist, the case-sensitivity convention of the codelist will be followed. It is highly recommended that (1) new terms for CDISC Controlled Terminology extensible codelists and (2) Changes to existing terms and requests for new codelists be submitted to the National Cancer Institute (NCI) Enterprise Vocabulary Services (EVS) for review and consideration.
