Guidance on how to interpret the contents of this table can be found here
| 0. Identifier | |
| Definition | An identifier - identifies some entity uniquely and unambiguously. Typically this is used for business identifiers. |
| Short | An identifier intended for computation |
| 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())) |
| 2. Identifier.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 IdentifierUsehttp://hl7.org/fhir/ValueSet/identifier-use|4.0.1 (required to http://hl7.org/fhir/ValueSet/identifier-use|4.0.1 |
| 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())) |
| 4. Identifier.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 | 10..1 |
| Type | uri |
| Is Modifier | false |
| Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
| 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. |
| Fixed Value | urn:oid:2.16.438.10.20.10.10.1.2.1 |
| Example | <br/><b>General</b>:http://www.acme.com/identifiers/patient |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
| 6. Identifier.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. |
| Control | 10..1 |
| Type | string |
| Is Modifier | false |
| Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
| Summary | true |
| Example | <br/><b>General</b>:123456 |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) idn-length: IDN must be 13 digits long ( value.matches('^[0-9]{13}$')) |

| 0. Identifier | |
| Definition | An identifier - identifies some entity uniquely and unambiguously. Typically this is used for business identifiers. |
| Short | An identifier intended for computation |
| 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())) |
| 2. Identifier.id | |
| Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Short | Unique id for inter-element referencing |
| Control | 0..1 |
| Type | string |
| Is Modifier | false |
| XML Format | In the XML format, this property is represented as an attribute. |
| Summary | false |
| 4. Identifier.extension | |
| Definition | 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 | Additional 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. |
| Control | 0..* |
| Type | Extension |
| Is Modifier | false |
| Summary | false |
| Alternate Names | extensions, user content |
| 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()) |
| Slicing | This element introduces a set of slices on Identifier.extension. The slices are unordered and Open, and can be differentiated using the following discriminators:
|
| 6. Identifier.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 (required to http://hl7.org/fhir/ValueSet/identifier-use|4.0.1 |
| 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())) |
| 8. Identifier.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 (extensible to http://hl7.org/fhir/ValueSet/identifier-type |
| Type | CodeableConcept |
| Is Modifier | false |
| 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())) |
| 10. Identifier.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. |

| Definition | Organization that issued/manages the identifier. |
| Short | Organization that issued id (may be just text) |
| Comments | The Identifier.assigner may omit the .reference element and only contain a .display element reflecting the name or other textual information about the assigning organization. |
