"description": "A concept descriptor represents any kind of concept usually by giving a code defined in a code system. A concept descriptor can contain the original text or phrase that served as the basis of the coding and one or more translations into different coding systems. A concept descriptor can also contain qualifiers to describe, e.g., the concept of a \"left foot\" as a postcoordinated term built from the primary code \"FOOT\" and the qualifier \"LEFT\". In cases of an exceptional value, the concept descriptor need not contain a code but only the original text describing that concept.",
