SNOMED CT 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. 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 

• Left kidney structure (body structure) LATERALITY Left (qualifier value) 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 (disorder) FINDING SITE Lung structure (body structure)

Examples of Qualifier value concepts: 

• Unilaterial (qualifier value) 
• Left (qulifier value)
• Puncture - action (qualifier value)
