}Expand description
The CodeSystem resource is used to declare the existence of and describe a code system or code system supplement and its key properties, and optionally define a part or all of its content.
CodeSystem v5.0.0
Declares the existence of and describes a code system or code system supplement
The CodeSystem resource is used to declare the existence of and describe a code system or code system supplement and its key properties, and optionally define a part or all of its content.
Fields§
§id: Option<String>Logical id of this artifact
The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.
Within the context of the FHIR RESTful interactions, the resource has an id except for cases like the create and conditional update. Otherwise, the use of the resouce id depends on the given use case.
meta: Option<Meta>Metadata about the resource
The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.
implicit_rules: Option<String>A set of rules under which this content was created
A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.
Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of its narrative along with other profiles, value sets, etc.
language: Option<String>Language; Language of the resource content
The base language in which the resource is written.
Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).
text: Option<Narrative>Text summary of the resource, for human interpretation
A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it “clinically safe” for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.
Contained resources do not have a narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a “text blob” or where text is additionally entered raw or narrated and encoded information is added later.
contained: Vec<Resource>Contained, inline Resources
These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning.
This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags in their meta elements, but SHALL NOT have security labels.
extension: Vec<Extension>Additional content defined by implementations
May be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
modifier_extension: Vec<Extension>Extensions that cannot be ignored
May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element’s descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.
Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
url: Option<String>Canonical identifier for this code system, represented as a URI (globally unique) (Coding.system)
An absolute URI that is used to identify this code system when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which an authoritative instance of this code system is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the code system is stored on different servers. This is used in Coding.system.
Can be a urn:uuid: or a urn:oid: but real http: addresses are preferred. Multiple instances may share the same URL if they have a distinct version.
The determination of when to create a new version of a resource (same url, new version) vs. defining a new artifact is up to the author. Considerations for making this decision are found in Technical and Business Versions.
In some cases, the resource can no longer be found at the stated url, but the url itself cannot change. Implementations can use the meta.source element to indicate where the current master source of the resource can be found.
url_ext: Option<FieldExtension>Extension field.
identifier: Vec<Option<Identifier>>Additional identifier for the code system (business identifier)
A formal identifier that is used to identify this code system when it is represented in other formats, or referenced in a specification, model, design or an instance.
Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, and can then identify this code system outside of FHIR, where it is not possible to use the logical URI. Note that HL7 defines at least three identifiers for many of its code systems - the FHIR canonical URL, the OID and the V2 Table 0396 mnemonic code.
identifier_ext: Vec<Option<FieldExtension>>Extension field.
version: Option<String>Business version of the code system (Coding.version)
The identifier that is used to identify this version of the code system when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the code system author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. This is used in Coding.version.
There may be different code system instances that have the same identifier but different versions. The version can be appended to the url in a reference to allow a reference to a particular business version of the code system with the format [url]|[version]. The version SHOULD NOT contain a ‘#’ - see Business Version.
version_ext: Option<FieldExtension>Extension field.
version_algorithm: Option<CodeSystemVersionAlgorithm>How to compare versions
Indicates the mechanism used to compare versions to determine which CodeSystem is more current.
If set as a string, this is a FHIRPath expression that has two additional context variables passed in - %version1 and %version2 and will return a negative number if version1 is newer, a positive number if version2 and a 0 if the version ordering can’t be successfully be determined.
version_algorithm_ext: Option<CodeSystemVersionAlgorithmExtension>Extension field.
name: Option<String>Name for this code system (computer friendly)
A natural language name identifying the code system. This name should be usable as an identifier for the module by machine processing applications such as code generation.
The name is not expected to be globally unique. The name should be a simple alphanumeric type name to ensure that it is machine-processing friendly.
name_ext: Option<FieldExtension>Extension field.
title: Option<String>Name for this code system (human friendly)
A short, descriptive, user-friendly title for the code system.
This name does not need to be machine-processing friendly and may contain punctuation, white-space, etc.
title_ext: Option<FieldExtension>Extension field.
status: PublicationStatusPublicationStatus; draft | active | retired | unknown
The status of this code system. Enables tracking the life-cycle of the content.
Allows filtering of code systems that are appropriate for use versus not.
See guidance around (not) making local changes to elements here.
status_ext: Option<FieldExtension>Extension field.
experimental: Option<bool>For testing purposes, not real usage
A Boolean value to indicate that this code system is authored for testing purposes (or education/evaluation/marketing) and is not intended to be used for genuine usage.
Allows filtering of code systems that are appropriate for use versus not.
experimental_ext: Option<FieldExtension>Extension field.
date: Option<DateTime>Date last changed
The date (and optionally time) when the code system was last significantly changed. The date must change when the business version changes and it must change if the status code changes. In addition, it should change when the substantive content of the code system changes.
The date is often not tracked until the resource is published, but may be present on draft content. Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the code system. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.
See guidance around (not) making local changes to elements here.
date_ext: Option<FieldExtension>Extension field.
publisher: Option<String>Name of the publisher/steward (organization or individual)
The name of the organization or individual responsible for the release and ongoing maintenance of the code system.
Usually an organization but may be an individual. The publisher (or steward) of the code system is the organization or individual primarily responsible for the maintenance and upkeep of the code system. This is not necessarily the same individual or organization that developed and initially authored the content. The publisher is the primary point of contact for questions or issues with the code system. This item SHOULD be populated unless the information is available from context.
publisher_ext: Option<FieldExtension>Extension field.
contact: Vec<Option<ContactDetail>>Contact details for the publisher
Contact details to assist a user in finding and communicating with the publisher.
May be a web site, an email address, a telephone number, etc.
See guidance around (not) making local changes to elements here.
contact_ext: Vec<Option<FieldExtension>>Extension field.
description: Option<String>Natural language description of the code system
A free text natural language description of the code system from a consumer’s perspective.
This description can be used to capture details such as comments about misuse, instructions for clinical use and interpretation, literature references, examples from the paper world, etc. It is not a rendering of the code system as conveyed in the ‘text’ field of the resource itself. This item SHOULD be populated unless the information is available from context (e.g. the language of the code system is presumed to be the predominant language in the place the code system was created).
description_ext: Option<FieldExtension>Extension field.
use_context: Vec<Option<UsageContext>>The context that the content is intended to support
The content was developed with a focus and intent of supporting the contexts that are listed. These contexts may be general categories (gender, age, …) or may be references to specific programs (insurance plans, studies, …) and may be used to assist with indexing and searching for appropriate code system instances.
When multiple useContexts are specified, there is no expectation that all or any of the contexts apply.
use_context_ext: Vec<Option<FieldExtension>>Extension field.
jurisdiction: Vec<Option<CodeableConcept>>Jurisdiction; Intended jurisdiction for code system (if applicable)
A legal or geographic region in which the code system is intended to be used.
It may be possible for the code system to be used in jurisdictions other than those for which it was originally designed or intended.
DEPRECATION NOTE: For consistency, implementations are encouraged to migrate to using the new ‘jurisdiction’ code in the useContext element. (I.e. useContext.code indicating http://terminology.hl7.org/CodeSystem/usage-context-type#jurisdiction and useContext.valueCodeableConcept indicating the jurisdiction.)
jurisdiction_ext: Vec<Option<FieldExtension>>Extension field.
purpose: Option<String>Why this code system is defined
Explanation of why this code system is needed and why it has been designed as it has.
This element does not describe the usage of the code system. Instead, it provides traceability of ’‘why’’ the resource is either needed or ’‘why’’ it is defined as it is. This may be used to point to source materials or specifications that drove the structure of this code system.
purpose_ext: Option<FieldExtension>Extension field.
copyright: Option<String>Use and/or publishing restrictions
A copyright statement relating to the code system and/or its contents. Copyright statements are generally legal restrictions on the use and publishing of the code system.
… Sometimes, the copyright differs between the code system and the codes that are included. The copyright statement should clearly differentiate between these when required.
copyright_ext: Option<FieldExtension>Extension field.
copyright_label: Option<String>Copyright holder and year(s)
A short string (<50 characters), suitable for inclusion in a page footer that identifies the copyright holder, effective period, and optionally whether rights are resctricted. (e.g. ‘All rights reserved’, ‘Some rights reserved’).
The (c) symbol should NOT be included in this string. It will be added by software when rendering the notation. Full details about licensing, restrictions, warrantees, etc. goes in the more general ‘copyright’ element.
copyright_label_ext: Option<FieldExtension>Extension field.
approval_date: Option<Date>When the CodeSystem was approved by publisher
The date on which the resource content was approved by the publisher. Approval happens once when the content is officially approved for usage.
The ‘date’ element may be more recent than the approval date because of minor changes or editorial corrections.
See guidance around (not) making local changes to elements here.
approval_date_ext: Option<FieldExtension>Extension field.
last_review_date: Option<Date>When the CodeSystem was last reviewed by the publisher
The date on which the resource content was last reviewed. Review happens periodically after approval but does not change the original approval date.
If specified, this date follows the original approval date.
See guidance around (not) making local changes to elements here.
last_review_date_ext: Option<FieldExtension>Extension field.
effective_period: Option<Period>When the CodeSystem is expected to be used
The period during which the CodeSystem content was or is planned to be in active use.
The effective period for a CodeSystem determines when the content is applicable for usage and is independent of publication and review dates. For example, a system intended to be used for the year 2016 might be published in 2015.
See guidance around (not) making local changes to elements here.
effective_period_ext: Option<FieldExtension>Extension field.
topic: Vec<Option<CodeableConcept>>DefinitionTopic; E.g. Education, Treatment, Assessment, etc
Descriptions related to the content of the CodeSystem. Topics provide a high-level categorization as well as keywords for the CodeSystem that can be useful for filtering and searching.
DEPRECATION NOTE: For consistency, implementations are encouraged to migrate to using the new ‘topic’ code in the useContext element. (I.e. useContext.code indicating http://terminology.hl7.org/CodeSystem/usage-context-type#topic and useContext.valueCodeableConcept indicating the topic)
topic_ext: Vec<Option<FieldExtension>>Extension field.
Who authored the CodeSystem
An individiual or organization primarily involved in the creation and maintenance of the CodeSystem.
Extension field.
editor: Vec<Option<ContactDetail>>Who edited the CodeSystem
An individual or organization primarily responsible for internal coherence of the CodeSystem.
editor_ext: Vec<Option<FieldExtension>>Extension field.
reviewer: Vec<Option<ContactDetail>>Who reviewed the CodeSystem
An individual or organization asserted by the publisher to be primarily responsible for review of some aspect of the CodeSystem.
See guidance around (not) making local changes to elements here.
reviewer_ext: Vec<Option<FieldExtension>>Extension field.
endorser: Vec<Option<ContactDetail>>Who endorsed the CodeSystem
An individual or organization asserted by the publisher to be responsible for officially endorsing the CodeSystem for use in some setting.
See guidance around (not) making local changes to elements here.
endorser_ext: Vec<Option<FieldExtension>>Extension field.
Additional documentation, citations, etc
Related artifacts such as additional documentation, justification, dependencies, bibliographic references, and predecessor and successor artifacts.
Each related artifact is either an attachment, or a reference to another resource, but not both.
Extension field.
case_sensitive: Option<bool>If code comparison is case sensitive
If code comparison is case sensitive when codes within this system are compared to each other.
If this value is missing, then it is not specified whether a code system is case sensitive or not. When the rule is not known, Postel’s law should be followed: produce codes with the correct case, and accept codes in any case. This element is primarily provided to support validation software.
case_sensitive_ext: Option<FieldExtension>Extension field.
value_set: Option<String>Canonical reference to the value set with entire code system
Canonical reference to the value set that contains all codes in the code system independent of code status.
The definition of the value set SHALL include all codes from this code system, independent of concept status, and only codes from this code system. It SHALL be immutable, and operations SHOULD support validation of any allowed code compositions.
value_set_ext: Option<FieldExtension>Extension field.
hierarchy_meaning: Option<CodeSystemHierarchyMeaning>CodeSystemHierarchyMeaning; grouped-by | is-a | part-of | classified-with
The meaning of the hierarchy of concepts as represented in this resource.
Note that other representations might have a different hierarchy or none at all, and represent the information using properties.
hierarchy_meaning_ext: Option<FieldExtension>Extension field.
compositional: Option<bool>If code system defines a compositional grammar
The code system defines a compositional (post-coordination) grammar.
Note that the code system resource does not define what the compositional grammar is, only whether or not there is one.
compositional_ext: Option<FieldExtension>Extension field.
version_needed: Option<bool>If definitions are not stable
This flag is used to signify that the code system does not commit to concept permanence across versions. If true, a version must be specified when referencing this code system.
Best practice is that code systems do not redefine concepts, or that if concepts are redefined, a new code system definition is created. But this is not always possible, so some code systems may be defined as ‘versionNeeded’.
Most code systems occasionally refine the displays defined for concepts between versions. Contexts in which the concept display values are validated may require that the version be specified for some code systems irrespective of the value of this property.
version_needed_ext: Option<FieldExtension>Extension field.
content: CodeSystemContentModeCodeSystemContentMode; not-present | example | fragment | complete | supplement
The extent of the content of the code system (the concepts and codes it defines) are represented in this resource instance.
content_ext: Option<FieldExtension>Extension field.
supplements: Option<String>Canonical URL of Code System this adds designations and properties to
The canonical URL of the code system that this code system supplement is adding designations and properties to.
The most common use of a code system supplement is to add additional language support.
supplements_ext: Option<FieldExtension>Extension field.
count: Option<u32>Total concepts in the code system
The total number of concepts defined by the code system. Where the code system has a compositional grammar, the basis of this count is defined by the system steward.
The count of concepts defined in this resource cannot be more than this value but may be less for several reasons - see the content element.
count_ext: Option<FieldExtension>Extension field.
filter: Vec<Option<CodeSystemFilter>>Filter that can be used in a value set
A filter that can be used in a value set compose statement when selecting concepts using a filter.
Note that filters defined in code systems usually require custom code on the part of any terminology engine that will make them available for use in value set filters. For this reason, they are generally only seen in high value published terminologies.
filter_ext: Vec<Option<FieldExtension>>Extension field.
property: Vec<Option<CodeSystemProperty>>Additional information supplied about each concept
A property defines an additional slot through which additional information can be provided about a concept.
Multiple occurrences of CodeSystem.concept.property may occur for a CodeSystem.property where CodeSystem.concept.property.code is the same and CodeSystem.concept.property.value differs. For example: multiple designations for a single concept.
property_ext: Vec<Option<FieldExtension>>Extension field.
concept: Vec<Option<CodeSystemConcept>>Concepts in the code system
Concepts that are in the code system. The concept definitions are inherently hierarchical, but the definitions must be consulted to determine what the meanings of the hierarchical relationships are.
If this is empty, it means that the code system resource does not represent the content of the code system.
concept_ext: Vec<Option<FieldExtension>>Extension field.
