StructureDefinition BodyStructure

Only required where additional elements regarding the body site need to be captured, e.g. histology/morphology. If a simple SNOMED CT anatomical location code is sufficient, this SHOULD be captured in Specimen.bodySite.

For metastatic sites vs. primary, the Condition resource SHOULD be used instead, following guidance from the mCode FHIR IG

The Genomics BodyStructure is currently based on the HL7 international version of the resource as a profile for BodyStructure does not exist in UKCore. Once this profile becomes active in UKCore its suitability for use and need for profiling within Genomics will be assessed.

The base BodyStructure resource is provided below for completeness.

Usage

Use of this resource is meant to replace the Genomics extensions for topology and morphology on the Specimen profile

Additional Guidance

morphology

SHALL be provided where relevant. SHOULD use SNOMED CT encoding. SHOULD use a code under the `14799000 | Neoplasm, metastatic (morphologic abnormality)` concept if the sample has been collected from a metastatic site, as opposed to primary.
"morphology": {
  "coding": [
    {
      "system": "http://snomed.info/sct",
      "code": "53618008",
      "display": "Pancreatoblastoma"
    }
  ]
},

location

SHALL be provided where relevant. SHOULD use SNOMED CT encoding. Equivalent to Topography when used in conjunction with locationQualifier.

  "coding": [
    {

},

locationQualifier

SHALL be provided where relevant. SHOULD use SNOMED CT encoding.

  "coding": [
    {
