0. Extension
Definition | This extension allows additional identifiers to be included under ServiceRequest.performer and ServiceRequest.identifier Optional Extension Element - found in all resources.
Short | ExtensionOptional Extensions Element
Control | 0..* This element is affected by the following invariants: ele-1
Is Modifier | false
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (`extension.exists() != value.exists()`) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
2. Extension.extension
Definition | An Extension May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, 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.
Short | ExtensionAdditional content defined by implementations
Comments | 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.

4. Extension.url
Definition | Source of the definition for the extension code - a logical name or a URL.
Short | identifies the meaning of the extension
Comments | The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.

8. Extension.value[x].use
Definition | The purpose of this identifier.
Short | usual | official | temp | secondary | old (If known)
Comments | Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.
Control | 0..1
Binding | The codes SHALL be taken from IdentifierUse http://hl7.org/fhir/ValueSet/identifier-use|4.0.1 (required to `http://hl7.org/fhir/ValueSet/identifier-use|4.0.1` ) Identifies the purpose for this identifier, if known .
Type | code
Is Modifier | true because This is labeled as "Is Modifier" because applications should not mistake a temporary id for a permanent one.
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Requirements | Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
10. Extension.value[x].type
Definition | A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.
Short | Description of identifier
Comments | This element deals only with general categories of identifiers. It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage. Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known. There is not a 1:1 relationship between type and system, since many different systems have the same type.
Control | 0..1
Binding | Unless not suitable, these codes SHALL be taken from Identifier Type Codes http://hl7.org/fhir/ValueSet/identifier-type (extensible to `http://hl7.org/fhir/ValueSet/identifier-type` ) A coded type for an identifier that can be used to determine which identifier to use for a specific purpose.
Type | CodeableConcept
Is Modifier | false
Must Support | true
Summary | true
Requirements | Allows users to make use of identifiers when the identifier system is not known.
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
12. Extension.value[x].type.coding
Definition | A reference to a code defined by a terminology system.
Short | Code defined by a terminology system
Comments | Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.
Control | 0..*
Type | Coding
Is Modifier | false
Must Support | true
Summary | true
Requirements | Allows for alternative encodings within a code system, and translations to other code systems.
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
14. Extension.value[x].type.coding.system
Definition | The identification of the code system that defines the meaning of the symbol in the code.
Short | Identity of the terminology system
Comments | The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should reference to some definition that establishes the system clearly and unambiguously.
Control | 0..1

Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Must Support | true
Summary | true

Short | Representation defined by the system
Control | 0..1
Type | string
Is Modifier | false
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Must Support | true
Summary | true
Requirements | Need to be able to carry a human-readable meaning of the code for readers that do not know the system.
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
20. Extension.value[x].system
Definition | Establishes the namespace for the value - that is, a URL that describes a set values that are unique.
Short | The namespace for the identifier value
Comments | Identifier.system is always case sensitive.
Control | 0..1
Type | uri
Is Modifier | false
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Must Support | true
Summary | true
Requirements | There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.
Example | <br/><b>General</b>:http://www.acme.com/identifiers/patient

22. Extension.value[x].value
Definition | The portion of the identifier typically relevant to the user and which is unique within the context of the system.
Short | The value that is unique
Comments | If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.

Definition | Indicates that this coding was chosen by a user directly - e.g. off a pick list of available items (codes or displays).
Short | If this coding was chosen directly by the user
Comments | Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations.
