Filters

Code

Description

Value

concept

Filter that includes concepts based on their logical definition. e.g. [concept] [is-a] [x] - include all concepts with an is-a relationship to concept x, or [concept] [in] [x]- include all concepts in the reference set identified by concept x

is-a in

A SNOMED CT code

expression

The result of the filter is the result of executing the given SNOMED CT Expression Constraint

A SNOMED CT ECL expression (see http://snomed.org/ecl)

expressions

Whether post-coordinated expressions are included in the value set

true or false

Concepts

This case-insensitive code system http://snomed.info/sct defines codes in a Is-A hierarchy, but no codes are represented here
