This code system http://hl7.org/fhir/CodeSystem/additional-binding-purpose defines the following codes:
CodeDisplayDefinitionCopy
maximum Maximum Binding A required binding, for use when the binding strength is 'extensible' or 'preferred' btnbtn
minimum Minimum Binding The minimum allowable value set - any conformant system SHALL support all these codes btnbtn
required Required Binding This value set is used as a required binding (in addition to the base binding (not a replacement), usually in a particular usage context) btnbtn
extensible Conformance Binding This value set is used as an extensible binding (in addition to the base binding (not a replacement), usually in a particular usage context) btnbtn
candidate Candidate Binding This value set is a candidate to substitute for the overall conformance value set in some situations; usually these are defined in the documentation btnbtn
current Current Binding New records are required to use this value set, but legacy records may use other codes. The definition of 'new record' is difficult, since systems often create new records based on pre-existing data. Usually 'current' bindings are mandated by an external authority that makes clear rules around this btnbtn
preferred Preferred Binding This is the value set that is preferred in a given context (documentation should explain why) btnbtn
ui UI Suggested Binding This value set is provided for user look up in a given context. Typically, these valuesets only include a subset of codes relevant for input in a context btnbtn
starter Starter Binding This value set is a good set of codes to start with when designing your system btnbtn
component Component Binding This value set is a component of the base value set. Usually this is called out so that documentation can be written about a portion of the value set btnbtn
Explanation of the columns that may appear on this page:
Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
Display The 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
Definition An explanation of the meaning of the concept
