postcoordinated expression
postcoordinated expression
A SNOMED CT expression containing two or more concept identifiers that represent an idea.
Notes
The concept identifiers in a _ postcoordinated expression_ relate to one another in ways that build more specific clinical ideas. The required meaning is expressed by combining several clinical ideas, each of which is represented by an identified concept.
The syntax used to represent SNOMED CT expressions is called the SNOMED CT compositional grammar and is formally defined in the Compositional Grammar - Specification and Guide.
Example
The concept 125605004 | fracture of bone| can be refined using the attribute 363698007 | finding site| , and the body structure concept 71341001 | bone structure of femur| to create the following postcoordinated expression :
125605004 |fracture of bone| : 363698007 |finding site| = 71341001 |bone structure of femur|
