Description of: CDPH : Code_phrase

A code phrase is a list of code values which all together make up a meaning. This can be used for example in SNOMED, where you can combine multiple codes into a new composite meaning.

Component definitions for: CDPH : Code_phrase

modifier_cd :: SET<CRR>

A set of concept_role_relations that modify the meaning of the primary code in a code phrase. For example, if SNOMED RT defines a concept "leg", a role relation "has-laterality", and another concept "left", the concept role relation allows to add the modifier "has-laterality: left" to a primary code "leg" to construct the meaning "left leg". In this example "has-latrality: left" is an element in the Code_phrase.modifier_cd.

primary_cd :: CV

A code value that may be modified in this code phrase. For example, if SNOMED RT defines a concept "leg", a role relation "has-laterality", and another concept "left", the concept role relation allows to add the modifier "has-laterality: left" to a primary code "leg" to construct the meaning "left leg". In this example "leg" is the Code_phrase.primary_cd.
