6.2.1.17. Qualifier value

The | Qualifier value | hierarchy contains some of the concepts used as values for SNOMED CT attributes that are not contained elsewhere in SNOMED CT. Such a code may be used as the value of an attribute in a defining Relationship in pre-coordinated definitions, and/or as the value of an attribute in a qualifier in a post-coordinated expression. However, the values for attributes are not limited to this hierarchy and are also found in hierarchies other than | Qualifier value |.

For example, the value for the attribute | LATERALITY | in the concept shown below is taken from the | Qualifier value | hierarchy:
  • | Left kidney structure | | LATERALITY | | Left |.
However, the value for the attribute | FINDING SITE | in the concept shown below is taken from the | Body structure | hierarchy, not the | Qualifier value | hierarchy.
  • | Pneumonia | | FINDING SITE | | Lung structure |.
Examples of Qualifier value concepts:
  • | Unilateral |;
  • | Left |;
  • | Puncture - action |.
