| 2 | Coding Conformance | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Declares a profile that required the specific coding to be included in a list of Codings because of the binding. This allows reading applications to identify particular codings without processing the systems. | |
| 3 | Coding Purpose | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | A reason that this coding is present. | |
| 4 | Extension UK Core Coding SCT Description Display | fhir.r4.ukcore.stu1#1.0.4 | R4 | The description display term for a SNOMED CT concept. The description display term associated with the ID within the sctdescid extension 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. | |
| 5 | IsPrimary | hl7.org.nz.fhir.ig.formulary#current | R4B | Is primary code within given context, e.g. primary Pharmacode® when multiple given | |
