Type

Definition
Indicates whether the issue indicates a variation from successful processing.
Comment
This is labeled as "Is Modifier" because applications should not confuse hints and warnings with errors.
Requirements
Indicates how relevant the issue is to the overall success of the action.

How the issue affects the success of the action.

Type
Cardinality

Definition
Describes the type of the issue. The system that creates an OperationOutcome SHALL choose the most applicable code from the IssueType value set, and may additional provide its own code for the error in the details element.
Comment
Requirements
Expresses the issue in a human and computer-friendly way, allowing the requesting system to behave differently based on the type of issue.
The required element provides a base level of computable interoperability across all systems for processing an outcome, allowing systems to respond appropriately regardless of the internal system error codes returned.

A code that describes the type of issue.

Type

Definition
A reference to a code defined by a terminology system.
Comment
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.
Requirements
Allows for alternative encodings within a code system, and translations to other code systems.

OperationOutcome.issue.details.CodeableConcept.coding.Coding.system
Id
Coding.system
Type
Cardinality
0 - 1
Definition
The identification of the code system that defines the meaning of the symbol in the code.
Comment
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.
Requirements
Need to be unambiguous about the source of the definition of the symbol.

All FHIR elements must have a @value or children
Path
OperationOutcome.issue.details.CodeableConcept.coding.Coding.version
Id
Coding.version
Type
Cardinality
0 - 1
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.
Comment
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.

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).

Type

Definition
A representation of the meaning of the code in the system, following the rules of the system.
Comment
Requirements
Need to be able to carry a human-readable meaning of the code for readers that do not know the system.

Path
OperationOutcome.issue.details.CodeableConcept.coding.Coding.userSelected
Id
Coding.userSelected
Type
Cardinality
0 - 1
Definition
Indicates that this coding was chosen by a user directly - e.g. off a pick list of available items (codes or displays).
Comment
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.
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.

Id
OperationOutcome.issue.location
Type
Cardinality
0 - *
Definition
This element is deprecated because it is XML specific. It is replaced by issue.expression, which is format independent, and simpler to parse.
For resource issues, this will be a simple XPath limited to element names, repetition indicators and the default child accessor that identifies one of the elements in the resource that caused this issue to be raised. For HTTP errors, will be "http." + the parameter name.
Comment
The root of the XPath is the resource or bundle that generated OperationOutcome. Each XPath SHALL resolve to a single node. This element is deprecated, and is being replaced by expression.
Requirements
Allows systems to highlight or otherwise guide users to elements implicated in issues to allow them to be fixed more easily.
