142 | SNOMED CT Release Format 1 (RF1) Guide July 2012 Table 66: Fully Specified Name Suffixes • administrative concept • body structure • disorder • ethnic group • geographic location • link assertion • namespace concept • occupation • physical force • product • record artifact • situation • specimen • tumor staging Note: • assessment scale • cell • environment / location • event • inactive concept • linkage concept • navigational concept • organism • physical object • qualifier value • regime/therapy • social concept • staging scale • attribute • cell structure • environment • finding • life style • morphologic abnormality • observable entity • person • procedure • racial group • religion/philosophy • special concept • substance The Fully Specified Name is not the same as the Preferred Term in the Descriptions Table. The Fully Specified Name explains the meaning of the concept more fully than the Preferred Term to remove or reduce ambiguity. The limitation in the length of this field is 255 bytes. All ASCII characters in the range32 to 127 can be encoded in a single byte using in UTF-8. However, accented and special characters require two or three byte encoding. The maximum length of a Term that contains these characters is less than 255 characters. The Fully Specified Name is also represented as a row in the Descriptions Table. This allows translated versions of the Fully Specified Name to co-exist and to be referenced by appropriate Language Subsets. The Fully Specified Name in the Concepts Table is the American English Fully Specified Name. Typically the Fully Specified Name will not be a Term that would be used in a clinical record. Instead, it may be stylized to ensure that it has a single unambiguous meaning. Example: The Preferred Term of a concept could be "Aspiration of stomach contents', however, the Fully Specified Name might be "Aspiration of stomach contents (procedure)' to distinguish it from a post-operative complication. 3.2.9.1.2.3. CTV3ID Table 67: CTV3ID Concepts Table Data Field CTV3ID Field Type String Permitted characters 0 to 9, A to Z, a to z or. (stop) Length The Read Code for the concept taken from the United Kingdom's Clinical Terms Version 3 terminology. As CTV3 is a superset of FourByte and Version 2 Read Codes, all the codes from those versions are present in CTV3 and SNOMED CT. The Identifiers can be picked out easily as all FourByte codes have a leading "." and Version 2 codes have a trailing ".". © 2002-2012 International Health Terminology Standards Development Organisation CVR #: 30363434 5
As new concepts are added to SNOMED Clinical Terms, new codes are used to populate this field. This will allow records to be maintained or searched using the existing codes and Identifiers during an extended migration period. The IHTSDO will review this commitment from time to time and it may be discontinued at some point in the future. In Extensions, these additional Identifier fields may not be populated. Note: The CTV3ID field should no longer be relied upon for mapping to and from the Read Codes. Additional mapping work in the UK identified some anomalies and resulted development of more flexibility table for Read Code Mapping 3.2.9.1.2.4. SNOMEDID Table 68: - Concepts Table Data Field SNOMEDID Field Type String The SNOMED RTidentifier for this concept. Permitted characters 0 to 9, A to Z or -(dash) Length 6 to 8 As new concepts are added to SNOMED Clinical Terms, new SNOMED Identifiers are generated to populate this field. This will allow records to be maintained or searched using the existing codes and Identifiers during an extended migration period. The IHTSDO will review this commitment from time to time and it may be discontinued at some point in the future. In Extensions, these additional Identifier fields may not be populated. 3.2.9.1.2.5. IsPrimitive Table 69: - Concepts Table Data Field IsPrimitive Field Type Boolean Permitted characters 0 or 1 Indicates if a Concept is Primitive or Fully defined by its defining characteristics. A Concept may be Primitive because: • Its only stated Defining characteristics are " | is a |"subtype Relationships • An aspect of its meaning is not fully expressed by existing Relationships. Length If a Concept is Primitive its place in the subtype hierarchy may be known but it cannot be checked for equivalence with another Concept expression or post-coordinated expression.
