140 | SNOMED CT Release Format 1 (RF1) Guide July 2012 The unique SNOMED CT Identifier for this clinical concept. See Component features - Identifiers (2.1.1.4.2) for an explanation of the SCTID data type format. 3.2.9.1.2. Data Fields The Concepts table contains the following data fields: • ConceptStatus • FullySpecifiedName; • CTV3ID • SNOMEDID • IsPrimitive 3.2.9.1.2.1. ConceptStatus Table 63: ConceptStatus Concepts Table Data Field ConceptStatus Field Type Enumerated Permitted characters See listed values Length 1 or 2 The status of a Concept indicates whether it is in active use and, if not, indicates the reason for withdrawal from current use. Table 64: ConceptStatus Values Value 0 1 2 3 4 5 Current Retired Duplicate Outdated Ambiguous Erroneous Meaning The Concept is in current use and is considered active. The Concept has been withdrawn without a specified reason. These concepts are considered inactive. The Concept has been withdrawn from current use because it duplicates another Concept.These concepts are considered inactive. The Concept has been withdrawn from current use because it is no longer recognized as a valid clinical concept. These concepts are considered inactive. The Concept has been withdrawn from current use because it is inherently ambiguous. These concepts are considered inactive. The Concept has been withdrawn from current use as it contains an error. A corrected but otherwise similar Concept may have been added to replace it. These concepts are considered inactive. © 2002-2012 International Health Terminology Standards Development Organisation CVR #: 30363434
Value 6 10 11 Limited Moved elsewhere Pending move 3.2.9.1.2.2. FullySpecifiedName Table 65: - Concepts Table Data Field FullySpecifiedName Field Type String Meaning The Concept is of limited clinical value as it is based on a classification concept or an administrative definition. Concepts with this status are not valid for current use and are considered inactive. The Concept has been moved to an extension, to a different extension, or to the International Release. Use the | Moved To |Relationship to locate the namespace to which the concept has been moved. These concepts are considered inactive. The Concept will be moved to an extension, to a different extension, or to the International Release. Use the | Moved To |Relationship to locate the namespace to which the concept will be moved when the recipient organization confirms the move. These concepts are considered active. Permitted characters Any (except LF, CR and TAB) A phrase that describes a Concept in a way that is intended to be unambiguous. Release File Formats | 141 Length 1 to 255 Each Fully Specified Name contains a suffix that indicates where it is integrated into the primary hierarchy. This can help distinguish, at a glance, for example, a finding from a disorder. © 2002-2012 International Health Terminology Standards Development Organisation CVR #: 30363434
