Query Concept Maps
This transaction allows a PoS, or any OHIE component, to access terminological information in the terminology service to query for Concept Maps. A typical example would be to request the set of Concept Maps whose target Code System is SNOMED CT. 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.
