Verify Code Existence
This transaction allows a PoS, or any OHIE component, to access terminological information in the terminology service to verify that a code exists. A typical example would be to validate that the codes contained in an incoming patient data message are, in fact, from a required code system, e.g. ICD-10 or LOINC.
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.Existence: Is a Concept Code present in a specified Code System. E,g., is '123XYZ' a valid Code in the ICD-10 Code System?
The following is a description of the interaction steps.
