The description display term for a SNOMED CT concept. The display term is important to enable the representation of the exact term that was entered by the clinician that recorded the data, or the exact term that a legacy code e.g. a Read v2 code has been translated to using an assured mapping table.
This extension supplements the coding-sctdescid extension to support the exchange of the selected display term for a SNOMED CT concept, which is currently not supported by the FHIR standard.
