SNOMED code elements should include the descrpitionId extension

[elementechemlyn]

The descriptionid extension is used to carry the snomed code for the preferred term description used in the display element.

From the Care Connect spec:

2.3 Sending a SNOMED CT concept with its associated preferred term

When sending a SNOMED CT concept id with its preferred term then code.coding.extension.descrpitionId, code.coding.code and code.coding.system SHALL be populated.

PSA Example:

<code>
  <coding>
   <extension url=https://fhir.hl7.org.uk/STU3/StructureDefinition/Extension coding-sctdescid>
     <extension url="descriptionId">
       <valueId value=”2772071000000119"/>
     </extension>
   </extension>
   <code value="1107811000000102"/>
    <display value="Prostate specific antigen mass concentration in serum"/>
    <system value=http://snomed.info/sct/>
   <userSelected value="true"/>
  </coding>
</code>
