| Control | 0..* This element is affected by the following invariants: ele-1 |
| 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()) |
| 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.

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.

| 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. |

| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
| 46. Extension.extension:ident.value[x].type.coding.version | |
| Definition | The version of the code system which was used when choosing this code. 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. |
| Short | Version of the system - if relevant |
| Comments | Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date. |
| Note | This is a business version Id, not a resource version Id (see discussion) |
| Control | 0..1 This element is affected by the following invariants: ele-1 |

| 48. Extension.extension:ident.value[x].type.coding.code | |
| Definition | A symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination). |
| Short | Symbol in syntax defined by the system |
| Comments | Note that FHIR strings SHALL NOT exceed 1MB in size |

| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
| 52. Extension.extension:ident.value[x].type.coding.userSelected | |
| 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. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely. |
| Control | 0..1 This element is affected by the following invariants: ele-1 |
| Type | boolean |
| Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
| Summary | true |
| Requirements | This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing. |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
| 54. Extension.extension:ident.value[x].type.text | |
| Definition | A human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user. |
| Short | Plain text representation of the concept |
| Comments | Very often the text is the same as a displayName of one of the codings. |
| Control | 0..1 This element is affected by the following invariants: ele-1 |
| Type | string |
| Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
| Summary | true |
| Requirements | The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source. |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
| 56. Extension.extension:ident.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 This element is affected by the following invariants: ele-1 |
| Type | uri |
| 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. |
| 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())) |
| 58. Extension.extension:ident.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. |

| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
| 60. Extension.extension:ident.value[x].period | |
| Definition | Time period during which identifier is/was valid for use. |
| Short | Time period when id is/was valid for use |
| Comments | A Period specifies a range of time; the context of use will specify whether the entire range applies (e.g. "the patient was an inpatient of the hospital for this time range") or one value from the range applies (e.g. "give to the patient between these two times"). Period is not used for a duration (a measure of elapsed time). See Duration. |

| 62. Extension.extension:ident.value[x].assigner | |
| 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. |
| Control | 0..1 This element is affected by the following invariants: ele-1 |
| Type | Reference(Organization) |

| 64. 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. |
