Implementation in XML Instance

The Identifier External data type flavour is used to carry this information in the XML element contentId as follows:
  • The XML attribute root is fixed to the OID "2.16.840.1.113883.2.1.3.2.4.18.16"
  • The XML attribute extension shall contain one of the allowed template artefact identifiers
[1..1] cRETypeListChoice (CRETypeListChoice)
A link to the CRE type list.
SectionChoice
An abstract placeholder for the templates of a section.
Used by: ClassificationSection
[1..1] : Template9
A link to the choice of section templates.
CodedEntry
An abstract placeholder for the templates of a coded entry.
Used by: ClassificationSection
[1..1] : Template
A link to templates for coded entries.
CRETypeListChoice
An abstract placeholder for the templates for CRE type lists.
Used by: ClassificationSection
[1..1] : Template10
A link to templates for a CRE type list.
ParentDocument
A related CDA document which is being referenced as the document being nullified (replaced).
Used by: ClinicalDocument
[1..1] [M] classCode (CS { CNE: ActClass } )
{ Fixed="DOCCLIN" }

Model Attribute Description

The HL7 attribute classCode uses a code to describe this class as a clinical document.

Implementation in XML Instance

The XML attribute classCode is fixed to " DOCCLIN".
[1..1] [M] moodCode (CS { CNE: ActMood } )
{ Fixed="EVN" }

Model Attribute Description

The HL7 attribute moodCode uses a code to describe this class as a clinical document event

Implementation in XML Instance

The XML attribute moodCode is fixed to " EVN".
[1..1] [M] code (CV { CWE:CDADocumentTypeSnCT } )

Model Attribute Description

The HL7 attribute code uses a code from SNOMED CT to describe the type of CDA document.

There are two possible representations for this attribute:

  • A single code from SNOMED CT
  • A composition grammar using multiple SNOMED CT codes

Note: Where the document being replaced (nullified) was not described using a code from SNOMED CT then other coding systems may be used instead.

Implementation in XML Instance

When using a single SNOMED CT code then:

The Coded Value (CV) data type shall be used to carry this information in the XML element code as follows:

  • The XML attribute code shall contain a code from the subset stated in CDADocumentTypeSnCT vocabulary
  • The XML attribute codeSystem shall contain the OID "2.16.840.1.113883.2.1.3.2.4.15"
  • The XML attribute displayName may carry a description associated with the code in the subset stated in the CDADocumentTypeSnCT vocabulary. It is recommended that the preferred term is used to populate this attribute

When using multiple SNOMED CT codes then:

The Coded Value (CV) data type shall be used to carry this information in the XML element code as follows:

  • The XML attribute code shall contain a string composed from codes from the subsets stated in CDADocumentTypeSnCT vocabulary as per the guidance in the vocabulary
  • The XML attribute codeSystem shall contain the OID "2.16.840.1.113883.2.1.3.2.4.15.1"
  • The XML attribute displayName may contain a string composed from the codes and descriptions from the subsets stated in CDADocumentTypeSnCT vocabulary as per the guidance in the vocabulary

Note: When the document being nullified was not coded using SNOMED CT then:

The Coded Value (CV) data type shall be used to carry this information in the XML element code as follows:

  • The XML attribute code shall contain the code used to code the document
  • The XML attribute codeSystem shall contain the OID for the code system
  • The XML attribute displayName may carry a description associated with the code

[1..1] [M] id (II)

Model Attribute Description

The HL7 attribute id uses an identifier to identify each unique instance of a parent clinical document.

Implementation in XML Instance

The Identifier Global data type flavour is used to carry the identifier in the XML element id as follows:
  • The XML attribute root shall contain a DCE UUID of the document being replaced (nullified)
[1..1] [M] setId (II)

Model Attribute Description

The HL7 attribute setId uses an identifier to identify all documents that are part of a set of documents.

Implementation in XML Instance

The Identifier Global data type flavour is used to carry the identifier in the XML element setId as follows:
  • The XML attribute root shall contain a DCE UUID
[1..1] [M] versionNumber (INT)

Model Attribute Description

The HL7 attribute versionNumber uses an integer value to allow versioning of the CDA document.

The version number here is the version number of the parent document that is being nullified.

Implementation in XML Instance

The XML element versionNumber is populated as follows:

  • The XML attribute value should contain the version number of the parent document being nullified as an integer value

Systems should nullify the version of the document carried here and any previous versions of the document stored on the system.

AuthenticatorChoice

An abstract placeholder for the templates for an authenticator.

Used by: ClinicalDocument
[1..1] : Template7
A link to templates for an authenticator.
DataEntererChoice

An abstract placeholder for the templates of a data enterer.

Used by: ClinicalDocument
[1..1] : Template5
A link to templates for a data enterer.
