## 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|](http://snomed.info/id/125605004) can be refined using the attribute [363698007 | finding site|](http://snomed.info/id/363698007) , and the body structure concept [71341001 | bone structure of femur|](http://snomed.info/id/71341001) to create the following *postcoordinated expression* :

[125605004 |fracture of bone|](http://snomed.info/id/125605004) : [363698007 |finding site|](http://snomed.info/id/363698007) = [71341001 |bone structure of femur|](http://snomed.info/id/71341001)
