1.22.2.1.145.1 ExtensionContext

How an extension context is interpreted

This value set defines its own terms in the system http://hl7.org/fhir/extension-context

CodeDefinition
resource The context is all elements matching a particular resource element path.
datatype The context is all nodes matching a particular data type element path (root or repeating element) or all elements referencing a particular primitive data type (expressed as the datatype name).
mapping The context is all nodes whose mapping to a specified reference model corresponds to a particular mapping structure. The context identifies the mapping target. The mapping should clearly identify where such an extension could be used.
extension The context is a particular extension from a particular profile. Expressed as uri#name, where uri identifies the profile and #name identifies the extension code.

This value set is used in the following places:

Explanation of the columns that may appear on this page:

LevelA few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
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)
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
DefinitionAn explanation of the meaning of the concept
CommentsAdditional notes about how to use the code

In addition, this page will include mappings to HL7 v2 or HL7 v3 code where these have been defined.
