Description: This transaction allows a PoS, or any OHIE component, to access terminological information in the terminology service to retrieve detailed information on a code. A typical example would be to retrieve descriptive information on a laboratory code from the LOINC Code System.
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.
Sponsor: Jack Bowie
Status: This operation has been extensively tested in FHIR Connectathons.
