Content

Extensions:
data-absent-reason	Data Absent Reason : Provides a reason why the expected value or elements in the element that is extended are missing.
bodySite	BodyStructure Reference : Record details about the anatomical location of a specimen or body part. This resource may be used when a coded concept does not provide the necessary detail needed for the use case.
rendered-value	Rendered Value : Provides a rendered version of the value intended for human display. For example, a sensitive identifier (e.g. social security number) partially obscured by asterisks; a drivers licence number with dashes inserted; a date formatted as MMM dd, yyyy; etc.
geolocation	Geolocation : The absolute geographic location of the Location, expressed using the WGS84 datum (This is the same co-ordinate system used in KML).
translation	Translation : Language translation from base language of resource to another language.
tz-code	Timezone Code : An IANA timezone code for the timezone offset per BCP 175. The offset is specified as part of a dateTime/instant (or using the tzOffset extension on a date if necessary). The timezone code may also be provided to allow for human display of the location associated with the offset.
tz-offset	Timezone Offset : Timezone offset, for dates where timezone is not allowed as part of the base date.
relative-date	Relative Date Criteria : Specifies that a date is relative to some event. The event happens [Duration] after [Event].
language	Human Language : The Human Language of the item.
originalText	Original Text : A human language representation of the concept (resource/element) as seen/selected/uttered by the user who entered the data and/or which represents the full intended meaning of the user. This can be provided either directly as text, or as a url that is a reference to a portion of the narrative of a resource (DomainResource.text).
narrativeLink	Narrative Link : A human language representation of the concept (resource/element), as a url that is a reference to a portion of the narrative of a resource (DomainResource.text).
replaces	replaces : Indicates a resource that this resource is replacing.
display	Display Name : The title or other name to display when referencing a resource by canonical URL.
variable	Variable : Variable specifying a logic to generate a variable for use in subsequent logic. The name of the variable will be added to FHIRPath's context when processing descendants of the element that contains this extension.
ordinalValue	Ordinal Value : A numeric value that allows the comparison (less than, greater than) or other numerical manipulation of a concept (e.g. Adding up components of a score). Scores are usually a whole number, but occasionally decimals are encountered in scores.
designNote	Design Note : Information captured by the author/maintainer of the questionnaire for development purposes, not intended to be seen by users.
