A ValueSet resource instance specifies a set of codes drawn from one or more code systems, intended for use in a particular context. Value sets link between [CodeSystem](codesystem.html) definitions and their use in [coded elements](terminologies.html). A ValueSet resource instance specifies a set of codes drawn from one or more code systems, intended for use in a particular context. Value sets link between [CodeSystem](codesystem.html) definitions and their use in [coded elements](terminologies.html). If the element is present, it must have either a @value, an @id, or extensions An absolute URI that is used to identify this value set 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 value set is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the value set is stored on different servers. A formal identifier that is used to identify this value set when it is represented in other formats, or referenced in a specification, model, design or an instance. The identifier that is used to identify this version of the value set when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the value set 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. Indicates the mechanism used to compare versions to determine which ValueSet is more current. A natural language name identifying the value set. This name should be usable as an identifier for the module by machine processing applications such as code generation. A short, descriptive, user-friendly title for the value set. The status of this value set. Enables tracking the life-cycle of the content. The status of the value set applies to the value set definition (ValueSet.compose) and the associated ValueSet metadata. Expansions do not have a state. A Boolean value to indicate that this value set is authored for testing purposes (or education/evaluation/marketing) and no version of this resource will ever be intended for genuine usage. The date (and optionally time) when the value set metadata or content logical definition (.compose) was created or revised. The name of the organization or individual responsible for the release and ongoing maintenance of the value set. Contact details to assist a user in finding and communicating with the publisher. A free text natural language description of the value set from a consumer's perspective. The textual description specifies the span of meanings for concepts to be included within the Value Set Expansion, and also may specify the intended use and limitations of the Value Set. 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 value set instances. A legal or geographic region in which the authority that maintains the resource is operating. In general, the jurisdiction is also found in the useContext. The useContext may reference additional jurisdictions because the defining jurisdiction does not necessarily limit the jurisdictions of use. If this is set to 'true', then no new versions of the content logical definition can be created. Note: Other metadata might still change. Explanation of why this value set is needed and why it has been designed as it has. A copyright statement relating to the value set and/or its contents. Copyright statements are notices of intellectual property ownership and can include restrictions on the use and publishing of the value set. A short string (<50 characters), suitable for inclusion in a page footer that identifies the copyright holder, effective period, and optionally whether rights are restricted. (e.g. 'All rights reserved', 'Some rights reserved'). 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 on which the resource content was last reviewed. Review happens periodically after approval but does not change the original approval date. The period during which the ValueSet content was or is planned to be in active use. Descriptions related to the content of the ValueSet. Topics provide a high-level categorization as well as keywords for the ValueSet that can be useful for filtering and searching. An individiual or organization primarily involved in the creation and maintenance of the ValueSet. An individual or organization primarily responsible for internal coherence of the ValueSet. An individual or organization asserted by the publisher to be primarily responsible for review of some aspect of the ValueSet. An individual or organization asserted by the publisher to be responsible for officially endorsing the ValueSet for use in some setting. Related artifacts such as additional documentation, justification, dependencies, bibliographic references, and predecessor and successor artifacts. A set of criteria that define the contents of the value set by including or excluding codes selected from the specified code system(s) that the value set draws from. This is also known as the Content Logical Definition (CLD). A value set can also be "expanded", where the value set is turned into a simple collection of enumerated codes. This element holds the expansion, if it has been performed. A ValueSet resource instance specifies a set of codes drawn from one or more code systems, intended for use in a particular context. Value sets link between [CodeSystem](codesystem.html) definitions and their use in [coded elements](terminologies.html). The Locked Date is the effective date that is used to determine the version of all referenced Code Systems and Value Set Definitions included in the compose that are not already tied to a specific version. Whether inactive codes - codes that are not approved for current use - are in the value set. If inactive = true, inactive codes are to be included in the expansion, if inactive = false, the inactive codes will not be included in the expansion. If absent, the behavior is determined by the implementation, or by the applicable $expand parameters (but generally, inactive codes would be expected to be included). Include one or more codes from a code system or other value set(s). Exclude one or more codes from the value set based on code system filters and/or other value sets. A property to return in the expansion, if the client doesn't ask for any particular properties. May be either a code from the code system definition (convenient) or a the formal URI that refers to the property. The special value '*' means all properties known to the server. A ValueSet resource instance specifies a set of codes drawn from one or more code systems, intended for use in a particular context. Value sets link between [CodeSystem](codesystem.html) definitions and their use in [coded elements](terminologies.html). An absolute URI which is the code system from which the selected codes come from. The version of the code system that the codes are selected from, or the special version '*' for all versions. Specifies a concept to be included or excluded. Select concepts by specifying a matching criterion based on the properties (including relationships) defined by the system, or on filters defined by the system. If multiple filters are specified within the include, they SHALL all be true. Selects the concepts found in this value set (based on its value set definition). This is an absolute URI that is a reference to ValueSet.url. If multiple value sets are specified this includes the intersection of the contents of all of the referenced value sets. A copyright statement for the specific code system asserted by the containing ValueSet.compose.include element's system value (if the associated ValueSet.compose.include.version element is not present); or the code system and version combination (if the associated ValueSet.compose.include.version element is present). A ValueSet resource instance specifies a set of codes drawn from one or more code systems, intended for use in a particular context. Value sets link between [CodeSystem](codesystem.html) definitions and their use in [coded elements](terminologies.html). Specifies a code for the concept to be included or excluded. The text to display to the user for this concept in the context of this valueset. If no display is provided, then applications using the value set use the display specified for the code by the system. Additional representations for this concept when used in this value set - other languages, aliases, specialized purposes, used for particular purposes, etc. A ValueSet resource instance specifies a set of codes drawn from one or more code systems, intended for use in a particular context. Value sets link between [CodeSystem](codesystem.html) definitions and their use in [coded elements](terminologies.html). The language this designation is defined for.

A ValueSet resource instance specifies a set of codes drawn from one or more code systems, intended for use in a particular context. Value sets link between [CodeSystem](codesystem.html) definitions and their use in [coded elements](terminologies.html). A code that identifies a property or a filter defined in the code system. The kind of operation to perform as a part of the filter criteria. ValueSet.compose.include.filter.value is represented as a string, and the string value must be [as described](valueset.html#filter-values). A ValueSet resource instance specifies a set of codes drawn from one or more code systems, intended for use in a particular context. Value sets link between [CodeSystem](codesystem.html) definitions and their use in [coded elements](terminologies.html). An identifier that uniquely identifies this expansion of the valueset, based on a unique combination of the provided parameters, the system default parameters, and the underlying system code system versions etc. Systems may re-use the same identifier as long as those factors remain the same, and the expansion is the same, but are not required to do so. This is a business identifier. As per paging Search results, the next URLs are opaque to the client, have no dictated structure, and only the server understands them. The time at which the expansion was produced by the expanding system. The total number of concepts in the expansion. If the number of concept nodes in this resource is less than the stated number, then the server can return more using the offset parameter. If paging is being used, the offset at which this resource starts. I.e. this resource is a partial view into the expansion. If paging is not being used, this element SHALL NOT be present. A parameter that controlled the expansion process. These parameters may be used by users of expanded value sets to check whether the expansion is suitable for a particular purpose, or to pick the correct expansion. A property defines an additional slot through which additional information can be provided about a concept. The codes that are contained in the value set expansion. A ValueSet resource instance specifies a set of codes drawn from one or more code systems, intended for use in a particular context.

One possible source of meaning is the [Concept Properties](codesystem-concept-properties.html) code system. A ValueSet resource instance specifies a set of codes drawn from one or more code systems, intended for use in a particular context. Value sets link between [CodeSystem](codesystem.html) definitions and their use in [coded elements](terminologies.html). An absolute URI which is the code system in which the code for this item in the expansion is defined. If true, this entry is included in the expansion for navigational purposes, and the user cannot select the code directly as a proper value. If the concept is inactive in the code system that defines it. Inactive codes are those that are no longer to be used, but are maintained by the code system for understanding legacy data. It might not be known or specified whether a concept is inactive (and it may depend on the context of use). The version of the code system from this code was taken. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged. The code for this item in the expansion hierarchy. If this code is missing the entry in the hierarchy is a place holder (abstract) and does not represent a valid code in the value set. The recommended display for this item in the expansion.
