This Value Set is normative - it is generated based on the information defined in this specification. The definition will remain fixed across versions, but the actual contents will change from version to version

This value set is used in the following places:


This expansion generated 21 May 2022

This value set contains 69 concepts

Expansion based on DataType v4.6.0 (CodeSystem)

All codes in this table are from the system

AddressAddressAn address expressed using postal conventions (as opposed to GPS or other location definition formats). This data type may be used to convey addresses for use in delivering mail as well as for visiting locations which might not be valid for mail delivery. There are a variety of postal address formats defined around the world.
AgeAgeA duration of time during which an organism (or a process) has existed.
AnnotationAnnotationA text note which also contains information about who made the statement and when.
AttachmentAttachmentFor referring to data content defined in other formats.
BackboneElementBackboneElementBase definition for all elements that are defined inside a resource - but not those in a data type.
BackboneTypeBackboneTypeBase definition for the few data types that are allowed to carry modifier extensions.
BaseBaseBase definition for all types defined in FHIR type system.
CodeableConceptCodeableConceptA concept that may be defined by a formal reference to a terminology or ontology or may be provided by text.
CodeableReferenceCodeableReferenceA reference to a resource (by instance), or instead, a reference to a concept defined in a terminology or ontology (by class).
CodingCodingA reference to a code defined by a terminology system.
ContactDetailContactDetailSpecifies contact information for a person or organization.
ContactPointContactPointDetails for all kinds of technology mediated contact points for a person or organization, including telephone, email, etc.
ContributorContributorA contributor to the content of a knowledge asset, including authors, editors, reviewers, and endorsers.
CountCountA measured amount (or an amount that can potentially be measured). Note that measured amounts include amounts that are not precisely quantified, including amounts involving arbitrary units and floating currencies.
DataRequirementDataRequirementDescribes a required data item for evaluation in terms of the type of data, and optional code or date-based filters of the data.
DataTypeDataTypeThe base class for all re-useable types defined as part of the FHIR Specification.
DistanceDistanceA length - a value with a unit that is a physical distance.
DosageDosageIndicates how the medication is/was taken or should be taken by the patient.
DurationDurationA length of time.
ElementElementBase definition for all elements in a resource.
ElementDefinitionElementDefinitionCaptures constraints on each element within the resource, profile, or extension.
ExpressionExpressionA expression that is evaluated in a specified context and returns a value. The context of use of the expression must specify the context in which the expression is evaluated, and how the result of the expression is used.
ExtendedContactDetailExtendedContactDetailSpecifies contact information for a specific purpose over a period of time, might be handled/monitored by a specific named person or organization.
ExtensionExtensionOptional Extension Element - found in all resources.
HumanNameHumanNameA human's name with the ability to identify parts and usage.
IdentifierIdentifierAn identifier - identifies some entity uniquely and unambiguously. Typically this is used for business identifiers.
MarketingStatusMarketingStatusThe marketing status describes the date when a medicinal product is actually put on the market or the date as of which it is no longer available.
MetaMetaThe metadata about a resource. This is content in the resource that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.
MoneyMoneyAn amount of economic utility in some recognized currency.
NarrativeNarrativeA human-readable summary of the resource conveying the essential clinical and business information for the resource.
ParameterDefinitionParameterDefinitionThe parameters to the module. This collection specifies both the input and output parameters. Input parameters are provided by the caller as part of the $evaluate operation. Output parameters are included in the GuidanceResponse.
PeriodPeriodA time period defined by a start and end date and optionally time.
PopulationPopulationA populatioof people with some set of grouping criteria.
PrimitiveTypePrimitiveTypeThe base type for all re-useable types defined that have a simple property.
ProductShelfLifeProductShelfLifeThe shelf-life and storage information for a medicinal product item or container can be described using this class.
QuantityQuantityA measured amount (or an amount that can potentially be measured). Note that measured amounts include amounts that are not precisely quantified, including amounts involving arbitrary units and floating currencies.
RangeRangeA set of ordered Quantities defined by a low and high limit.
RatioRatioA relationship of two Quantity values - expressed as a numerator and a denominator.
RatioRangeRatioRangeA range of ratios expressed as a low and high numerator and a denominator.
ReferenceReferenceA reference from one resource to another.
RelatedArtifactRelatedArtifactRelated artifacts such as additional documentation, justification, or bibliographic references.
SampledDataSampledDataA series of measurements taken by a device, with upper and lower limits. There may be more than one dimension in the data.
SignatureSignatureA signature along with supporting context. The signature may be a digital signature that is cryptographic in nature, or some other signature acceptable to the domain. This other signature may be as simple as a graphical image representing a hand-written signature, or a signature ceremony Different signature approaches have different utilities.
TimingTimingSpecifies an event that may occur multiple times. Timing schedules are used to record when things are planned, expected or requested to occur. The most common usage is in dosage instructions for medications. They are also used when planning care of various kinds, and may be used for reporting the schedule to which past regular activities were carried out.
TriggerDefinitionTriggerDefinitionA description of a triggering event. Triggering events can be named events, data events, or periodic, as determined by the type element.
UsageContextUsageContextSpecifies clinical/business/etc. metadata that can be used to retrieve, index and/or categorize an artifact. This metadata can either be specific to the applicable population (e.g., age category, DRG) or the specific context of care (e.g., venue, care setting, provider of care).
base64Binarybase64BinaryA stream of bytes
booleanbooleanValue of "true" or "false"
canonicalcanonicalA URI that is a reference to a canonical URL on a FHIR resource
codecodeA string which has at least one character and no leading or trailing whitespace and where there is no whitespace other than single spaces in the contents
datedateA date or partial date (e.g. just year or year + month). There is no UTC offset. The format is a union of the schema types gYear, gYearMonth and date. Dates SHALL be valid dates.
dateTimedateTimeA date, date-time or partial date (e.g. just year or year + month). If hours and minutes are specified, a UTC offset SHALL be populated. The format is a union of the schema types gYear, gYearMonth, date and dateTime. Seconds must be provided due to schema type constraints but may be zero-filled and may be ignored. Dates SHALL be valid dates.
decimaldecimalA rational number with implicit precision
ididAny combination of letters, numerals, "-" and ".", with a length limit of 64 characters. (This might be an integer, an unprefixed OID, UUID or any other identifier pattern that meets these constraints.) Ids are case-insensitive.
instantinstantAn instant in time - known at least to the second
integerintegerA whole number
integer64integer64A very large whole number
markdownmarkdownA string that may contain Github Flavored Markdown syntax for optional processing by a mark down presentation engine
oidoidAn OID represented as a URI
positiveIntpositiveIntAn integer with a value that is positive (e.g. >0)
stringstringA sequence of Unicode characters
timetimeA time during the day, with no date specified
unsignedIntunsignedIntAn integer with a value that is not negative (e.g. >= 0)
uriuriString of characters used to identify a name or a resource
urlurlA URI that is a literal reference
uuiduuidA UUID, represented as a URI
xhtmlXHTMLXHTML format, as defined by W3C, but restricted usage (mainly, no active content)

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
DefinitionAn explanation of the meaning of the concept
CommentsAdditional notes about how to use the code
