The identifier of the coding scheme in which the Coded Entry is defined.

See Section 8.2.

Shall be present if Code Value (0008,0100) or Long Code Value (0008,0119) is present. May be present otherwise.

Section 8.2

8.2 Coding Scheme Designator and Coding Scheme Version

The Attribute Coding Scheme Designator (0008,0102) identifies the coding scheme in which the code for a term is defined. Standard coding scheme designators used in DICOM information interchange are listed in PS3.16. Other coding scheme designators, for both private and public coding schemes, may be used, in accordance with PS3.16. Further identification of the coding scheme designators used in a SOP Instance may be provided in the Coding Scheme Identification Sequence (0008,0110) (see Section C.12.1).

Note

  1. Typical coding schemes used in DICOM include "DCM" for DICOM defined codes, "SCT" for SNOMED CT, and "LN" for LOINC. See Annex 8 “Coding Schemes” in PS3.16.

  2. Coding scheme designators beginning with "99" and the coding scheme designator "L" are defined in HL7 V2 to be private or local coding schemes.

  3. Most IODs that define the use of coded terms provide for the use of private codes and coding schemes through replacement of Baseline Context Groups or extension of Defined Context Groups. Systems supporting such private code use must provide a mechanism for the configuration of sets of Coding Scheme Designator (0008,0102), Code Value (0008,0100) (or Long Code Value (0008,0119) or URN Code Value (0008,0120)), and Code Meaning (0008,0104) to support interoperation of the private codes with other systems.

  4. It is highly recommended that local or non-standard coding schemes be identified in the Coding Scheme Identification Sequence (0008,0110). Documents or machine readable representations of the coding scheme (e.g., CSV or OWL files) can be linked to via a Coding Scheme URL (0008,010E). For appropriate values, see Table 8-1 “Coding Schemes” in PS3.16 .

  5. URN and URL codes usually lack a Coding Scheme Designator (0008,0102).

The Attribute Coding Scheme Version (0008,0103) may be used to identify the version of a coding scheme if necessary to resolve ambiguity in Code Value (0008,0100), Long Code Value (0008,0119) or URN Code Value (0008,0120). Coding Scheme Version (0008,0103) is not required for backward-compatible revisions of a coding scheme, as the Coding Scheme Designator (0008,0102) identifies the coding scheme as a whole as currently published by the responsible organization.

Note

  1. See PS3.16 for a discussion of SNOMED Coding Scheme Designators 99SDM, SNM3, SRT and SCT.

  2. ICD-10, for example, is not a backward-compatible revision of ICD-9, and hence it has a different Coding Scheme Designator, not simply a different Coding Scheme Version.
