All codes from system http://hl7.org/fhir/data-types

Code	Display	Definition
Address	Address	An 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.
Age	Age	A duration of time during which an organism (or a process) has existed.
Annotation	Annotation	A text note which also contains information about who made the statement and when.
Attachment	Attachment	For referring to data content defined in other formats.
BackboneElement	BackboneElement	Base definition for all elements that are defined inside a resource - but not those in a data type.
CodeableConcept	CodeableConcept	A concept that may be defined by a formal reference to a terminology or ontology or may be provided by text.
Coding	Coding	A reference to a code defined by a terminology system.
ContactDetail	ContactDetail	Specifies contact information for a person or organization.
ContactPoint	ContactPoint	Details for all kinds of technology mediated contact points for a person or organization, including telephone, email, etc.
Contributor	Contributor	A contributor to the content of a knowledge asset, including authors, editors, reviewers, and endorsers.
Count	Count	A 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.
DataRequirement	DataRequirement	Describes a required data item for evaluation in terms of the type of data, and optional code or date-based filters of the data.
Distance	Distance	A length - a value with a unit that is a physical distance.
Dosage	Dosage	Indicates how the medication is/was taken or should be taken by the patient.
Duration	Duration	A length of time.
Element	Element	Base definition for all elements in a resource.
ElementDefinition	ElementDefinition	Captures constraints on each element within the resource, profile, or extension.
Extension	Extension	Optional Extension Element - found in all resources.
HumanName	HumanName	A human's name with the ability to identify parts and usage.
Identifier	Identifier	A technical identifier - identifies some entity uniquely and unambiguously.
MarketingStatus	MarketingStatus	The 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.
Meta	Meta	The 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.
Money	Money	An amount of economic utility in some recognized currency.
Narrative	Narrative	A human-readable formatted text, including images.
ParameterDefinition	ParameterDefinition	The 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.
Period	Period	A time period defined by a start and end date and optionally time.
ProdCharacteristic	ProdCharacteristic	The 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.
ProductShelfLife	ProductShelfLife	The shelf-life and storage information for a medicinal product item or container can be described using this class.
Quantity	Quantity	A 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.
Range	Range	A set of ordered Quantities defined by a low and high limit.
Ratio	Ratio	A relationship of two Quantity values - expressed as a numerator and a denominator.
Reference	Reference	A reference from one resource to another.
RelatedArtifact	RelatedArtifact	Related artifacts such as additional documentation, justification, or bibliographic references.
SampledData	SampledData	A series of measurements taken by a device, with upper and lower limits. There may be more than one dimension in the data.
Signature	Signature	A 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.
SimpleQuantity	SimpleQuantity
SubstanceAmount	SubstanceAmount	Chemical substances are a single substance type whose primary defining element is the molecular structure. Chemical substances shall be defined on the basis of their complete covalent molecular structure; the presence of a salt (counter-ion) and/or solvates (water, alcohols) is also captured. Purity, grade, physical form or particle size are not taken into account in the definition of a chemical substance or in the assignment of a Substance ID.
SubstanceMoiety	SubstanceMoiety	Chemical substances are a single substance type whose primary defining element is the molecular structure. Chemical substances shall be defined on the basis of their complete covalent molecular structure; the presence of a salt (counter-ion) and/or solvates (water, alcohols) is also captured. Purity, grade, physical form or particle size are not taken into account in the definition of a chemical substance or in the assignment of a Substance ID.
Timing	Timing	Specifies 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.
TriggerDefinition	TriggerDefinition	A description of a triggering event. Triggering events can be named events, data events, or periodic, as determined by the type element.
UsageContext	UsageContext	Specifies 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).
base64Binary	base64Binary	A stream of bytes
boolean	boolean	Value of "true" or "false"
canonical	canonical	A URI that is a reference to a canonical URI on a FHIR resource
code	code	A 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
date	date	A date or partial date (e.g. just year or year + month). There is no time zone. The format is a union of the schema types gYear, gYearMonth and date. Dates SHALL be valid dates.
dateTime	dateTime	A date, date-time or partial date (e.g. just year or year + month). If hours and minutes are specified, a time zone 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.
decimal	decimal	A rational number with implicit precision
id	id	Any 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.
instant	instant	An instant in time - known at least to the second
integer	integer	A whole number
markdown	markdown	A string that may contain Github Flavored Markdown syntax for optional processing by a mark down presentation engine
oid	oid	An OID represented as a URI
positiveInt	positiveInt	An integer with a value that is positive (e.g. >0)
string	string	A sequence of Unicode characters
time	time	A time during the day, with no date specified
unsignedInt	unsignedInt	An integer with a value that is not negative (e.g. >= 0)
uri	uri	String of characters used to identify a name or a resource
url	url	A URI that is a literal reference
uuid	uuid	A UUID, represented as a URI
xhtml	XHTML	XHTML format, as defined by W3C, but restricted usage (mainly, no active content)

Explanation of the columns that may appear on this page:

Lvl

A 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

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
