| Requirements | Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers. | ||||||||
| Summary | true | ||||||||
| Comments | Applications can assume that an identifier is permanent unless it explicitly says that it is temporary. | ||||||||
| Identifier.type | |||||||||
| Element Id | Identifier.type | ||||||||
| Definition | A coded type for the identifier that can be used to determine which identifier to use for a specific purpose. | ||||||||
| Short Display | Description of identifier | ||||||||
| Cardinality | 0..1 | ||||||||
| Terminology Binding | Identifier Type Codes (Extensible) | ||||||||
| Type | CodeableConcept | ||||||||
| Requirements | Allows users to make use of identifiers when the identifier system is not known. | ||||||||
| Summary | true | ||||||||
| 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. | ||||||||
| Identifier.system | |||||||||
| Element Id | Identifier.system | ||||||||
| Definition | Establishes the namespace for the value - that is, an absolute URL that describes a set values that are unique. | ||||||||
| Short Display | The namespace for the identifier value | ||||||||
| Cardinality | 0..1 | ||||||||
| Type | uri | ||||||||
| 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. | ||||||||

| Comments | Identifier.system is always case sensitive. | ||||||||
| Identifier.value | |||||||||
| Element Id | Identifier.value | ||||||||
| Definition | The portion of the identifier typically relevant to the user and which is unique within the context of the system. | ||||||||
| Short Display | The value that is unique | ||||||||
| Cardinality | 0..1 | ||||||||
| Type | string | ||||||||
| Summary | true | ||||||||
| 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 http://hl7.org/fhir/StructureDefinition/rendered-value). 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. | ||||||||

| Cardinality | 0..* | ||||||||
| Type | DataType | ||||||||
| Requirements | References to codes are very common in healthcare models. | ||||||||
| Summary | true | ||||||||
| 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. | ||||||||
| Invariants |
| ||||||||
| Coding.system | |||||||||
| Element Id | Coding.system | ||||||||
| Definition | The identification of the code system that defines the meaning of the symbol in the code. | ||||||||
| Short Display | Identity of the terminology system | ||||||||
| Cardinality | 0..1 | ||||||||
| Type | uri | ||||||||
| Requirements | Need to be unambiguous about the source of the definition of the symbol. | ||||||||
| Summary | true | ||||||||
| 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 be an absolute reference to some definition that establishes the system clearly and unambiguously. | ||||||||
| Coding.version | |||||||||
| Element Id | 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 Display | Version of the system - if relevant | ||||||||
| Note | This is a business versionId, not a resource version id (see discussion) | ||||||||
| Cardinality | 0..1 | ||||||||
| Type | string | ||||||||
| Summary | true | ||||||||
| 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. | ||||||||
| Coding.code | |||||||||
| Element Id | 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 Display | Symbol in syntax defined by the system | ||||||||
| Cardinality | 0..1 | ||||||||
| Type | code | ||||||||
| Requirements | Need to refer to a particular code in the system. | ||||||||
| Summary | true | ||||||||

| Summary | true | ||||||||
| Invariants |
| ||||||||
| Coding.userSelected | |||||||||
| Element Id | 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 Display | If this coding was chosen directly by the user | ||||||||
| Cardinality | 0..1 | ||||||||
| Type | boolean | ||||||||
| 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. | ||||||||
| Summary | true | ||||||||
| 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. | ||||||||

| CodeableConcept | |
| Standards Status | This element has a standards status of "Normative" |
| Element Id | CodeableConcept |
| Definition | A concept that may be defined by a formal reference to a terminology or ontology or may be provided by text. |
| Short Display | Concept - reference to a terminology or just text |
| Cardinality | 0..* |
| Type | DataType |
| Requirements | This is a common pattern in healthcare - a concept that may be defined by one or more codes from formal definitions including LOINC and SNOMED CT, and/or defined by the provision of text that captures a human sense of the concept. |
| Summary | true |
| Comments | Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination. |
| CodeableConcept.coding | |
| Element Id | CodeableConcept.coding |
| Definition | A reference to a code defined by a terminology system. |
| Short Display | Code defined by a terminology system |
| Cardinality | 0..* |
| Type | Coding |
| Requirements | Allows for alternative encodings within a code system, and translations to other code systems. |
| Summary | true |
| 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. |
| CodeableConcept.text | |
| Element Id | CodeableConcept.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 Display | Plain text representation of the concept |
| Cardinality | 0..1 |
| Type | string |
| 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. |
| Summary | true |
| Comments | Very often the text is the same as a displayName of one of the codings. |

| Type | decimal | ||||||||
| Requirements | Precision is handled implicitly in almost all cases of measurement. | ||||||||
| Summary | true | ||||||||
| Comments | The implicit precision in the value should always be honored. Monetary values have their own rules for handling precision (refer to standard accounting text books). | ||||||||
| Quantity.comparator | |||||||||
| Element Id | Quantity.comparator | ||||||||
| Definition | How the value should be understood and represented - whether the actual value is greater or less than the stated value due to measurement issues; e.g. if the comparator is "<" , then the real value is < stated value. | ||||||||
| Short Display | < | <= | >= | > | ad - how to understand the value | ||||||||
| Cardinality | 0..1 | ||||||||
| Terminology Binding | QuantityComparator (Required) | ||||||||
| Type | code | ||||||||
| Is Modifier | true (Reason: This is labeled as "Is Modifier" because the comparator modifies the interpretation of the value significantly. If there is no comparator, then there is no modification of the value) | ||||||||
| Meaning if Missing | If there is no comparator, then there is no modification of the value | ||||||||
| Requirements | Need a framework for handling measures where the value is <5ug/L or >400mg/L due to the limitations of measuring methodology. | ||||||||
| Summary | true | ||||||||

E.g. it's possible to have multiple contacts with rank=1. If the ranks have different systems or uses, this would be interpreted to mean "X is my most preferred phone number, Y is my most preferred email address" or "X is my preferred home email and Y is my preferred work email". If the system and use for equally-ranked contacts are the same, then the level of preference is equivalent for both repetitions. Ranks need not be sequential and not all repetitions must have a rank. For example, it's possible to have 4 contacts with ranks of 2, 5 and two with no rank specified. That would be interpreted to mean the first is preferred over the second and no preference stated for the remaining contacts. | ||||||||
