## precoordinated expression

A SNOMED CT expression that containing a single concept identifier that represents an idea.

#### Notes

* *Precoordinated expressions* combine all aspects of a potentially multifaceted concept into a single discrete form.
* 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 procedure, laparoscopic emergency appendectomy\*\*\*\* can be represented with the *precoordinated expression* [174041007 |laparoscopic emergency appendectomy|](http://snomed.info/id/174041007) to record an instance of this procedure. This procedure has at least three distinct facets: *removal of appendix* ,*using a laparoscope* , and *as an emergency procedure*. SNOMED CT *precoordinates* these facets in one concept.
