This transaction allows a PoS, or any OHIE component, to access terminological information in the terminology service and retrieve the translation, or "mapping" of a Concept in one Code System to a Concept in another Code System. Mapping is frequently required when patient data is collected using Concepts/Codes from one Code System but the data must be reported or aggregated, say for decision support, in a different Code System. The set of such associated Concepts, usually for a specific use-case, are stored in the Terminology Service in a FHIR Resource called a ConceptMap.
Both external systems and systems inside the HIE may perform this transaction directly with the TS. The sequence diagram below shows the steps that occur for a system using this transaction.
- 1.Mapping: Using the ConceptMap 'ICD-10 to SNOMED CT Diseases', retrieve the SNOMED CT Concept Code(s) that is associated with '123XYZ' in ICD-10.
The following is a description of the interaction steps.
