Query Code Systems
This transaction allows a PoS, or any OHIE component, to access terminological information in the terminology service to query for Code Systems. A typical example would be to request the set of Code Systems defined by HL7.
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.
Query Code Systems: What Code Systems have a publisher name that contains 'HL7'?
Workflow Maturity | Mature |
|
Standards | The FHIR Code Systems and supported search parameters are defined in: https://www.hl7.org/fhir/codesystem.html. Searching in FHIR is described in https://www.hl7.org/fhir/search.html. HL7 FHIR Specifications v3.0 or higher support Code Systems. The response is a Bundle of CodeSystem Resources satisfying the search parameters. This workflow implements the IHE IT Infrastructure Technical Framework Supplement - Sharing Valuesets, Codes, and Maps (SVCM) Transaction: Query Code System ITI-Y2. | |
Assumptions and Prerequisites | The required Code Systems have been preloaded into the Terminology Service. | |
