CodeSystemDisplayDefinition
  usualhttp://hl7.org/fhir/identifier-useUsual

The identifier recommended for display and use in real-world interactions which should be used when such identifier is different from the "official" identifier.

  officialhttp://hl7.org/fhir/identifier-useOfficial

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.

  temphttp://hl7.org/fhir/identifier-useTemp

A temporary identifier.

  secondaryhttp://hl7.org/fhir/identifier-useSecondary

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.

  oldhttp://hl7.org/fhir/identifier-useOld

The identifier id no longer considered valid, but may be relevant for search purposes. E.g. Changes to identifier schemes, account merges, etc.

Explanation of the columns that may appear on this page:

LvlA few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
