Narrative

Note: links and images are rebased to the (stated) source

This code system http://hl7.org/fhir/identifier-use defines the following codes:

Code Display Definition
usual Usual The identifier recommended for display and use in real-world interactions which should be used when such identifier is different from the "official" identifier.
official Official The identifier considered to be most trusted for the identification of this item. Sometimes also known as "primary" and "main". The determination of "official" is subjective and implementation guides often provide additional guidelines for use.
temp Temp A temporary identifier.
secondary Secondary An identifier that was assigned in secondary use - it serves to identify the object in a relative context, but cannot be consistently assigned to the same object again in a different context.
old Old The identifier id no longer considered valid, but may be relevant for search purposes. E.g. Changes to identifier schemes, account merges, etc.
