FHIR Validate-Code Operations: SNOMED on FHIR Meeting, Vancouver Oct 2018
Download as PPTX, PDF0 likes58 views
The document discusses validating coded values against SNOMED CT using FHIR operations. It describes using SNOMED CT's versioned edition supplied in the version parameter and language matching the server's reference set. Basic use cases could return a boolean result and constrain the result to the code value only or add a coded display result parameter with values like valid, absent, unknown, or unmatched. It also provides a table outlining example code/display validation results and messages.

Normative operation in R4 Constrain Result to code value only? Add a (coded) Display Result Parameter? (valid, absent, unknown, unmatched, invalid…) The Issue At Hand…
