Definitions for the StructureDefinition-bluebutton-dme-line-pmt-80-100-cd-extension Profile.
Extension | |
Definition | Optional Extension Element - found in all resources. |
Control | 1..1 This element is affected by the following invariants: ele-1 |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
Extension.id | |
Definition | unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
Control | 1..1 This element is affected by the following invariants: ele-1 |
Type | string |
Comments | Note that FHIR strings may not exceed 1MB in size |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count())) |
Extension.extension | |
Definition | May be used to represent additional information that is not part of the basic definition of the element. In order 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. |
Control | 0..* This element is affected by the following invariants: ele-1 |
Type | Extension |
Alternate Names | extensions, user content |
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. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
Extension.url | |
Definition | Source of the definition for the extension code - a logical name or a URL. |
Control | 1..1 This element is affected by the following invariants: ele-1 |
Type | uri |
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. |
Fixed Value | https://bluebutton.cms.gov/assets/ig/StructureDefinition-bluebutton-dme-line-pmt-80-100-cd-extension |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count())) |
Extension.valueCoding(valueCoding) | |
Definition | Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list). |
Control | 1..1 This element is affected by the following invariants: ele-1 |
Type | Coding |
Comments | A stream of bytes, base64 encoded |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count())) |
Extension.valueCoding.id | |
Definition | unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
Control | 0..0 This element is affected by the following invariants: ele-1 |
Type | string |
Comments | Note that FHIR strings may not exceed 1MB in size |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count())) |

Extension.valueCoding.system | |
Definition | The identification of the code system that defines the meaning of the symbol in the code. |
Control | 1..1 This element is affected by the following invariants: ele-1 |
Type | uri |
Requirements | Need to be unambiguous about the source of the definition of the symbol. |
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 de-reference to some definition that establish the system clearly and unambiguously. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count())) |
Extension.valueCoding.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. |
Note | This is a business versionId, not a resource version id (see discussion) |
Control | 0..0 This element is affected by the following invariants: ele-1 |
Type | string |
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. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count())) |
Extension.valueCoding.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). |
Control | 1..1 This element is affected by the following invariants: ele-1 |
Type | code |
Requirements | Need to refer to a particular code in the system. |
Comments | Note that FHIR strings may not exceed 1MB in size |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count())) |
Extension.valueCoding.display | |
Definition | A representation of the meaning of the code in the system, following the rules of the system. |
Control | 1..1 This element is affected by the following invariants: ele-1 |
Type | string |
Requirements | Need to be able to carry a human-readable meaning of the code for readers that do not know the system. |
Comments | Note that FHIR strings may not exceed 1MB in size |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count())) |
Extension.valueCoding.userSelected | |
Definition | Indicates that this coding was chosen by a user directly - i.e. off a pick list of available items (codes or displays). |
Control | 0..0 This element is affected by the following invariants: ele-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. |
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. |
