8 Coding Schemes

Table 8-1 lists the coding schemes (and their designators) defined for use in DICOM; Table 8-2 lists the HL7v3 coding schemes referenced for use in DICOM. Additionally, any coding scheme may be used that has an entry in the HL7 Registry of Coding Schemes (HL7 v2 Table 0396, or the equivalent online registry), in which case the HL7 Symbolic Name shall be used as the value for the Coding Scheme Designator in DICOM, as long as it does not conflict with an entry Table 8-1 and fits within the Value Representation of the DICOM Coding Scheme Designator (0008,0102) attribute. As specified in the HL7 v2 Table 0396, local or private coding schemes shall be identified by an alphanumeric identifier beginning with the characters "99".

Note

  1. An earlier version of this table was formerly contained in Annex D of PS3.3.

  2. See Section 8.2 “Coding Scheme Designator and Coding Scheme Version” in PS3.3 for further description.

  3. The Coding Scheme UIDs are provided for reference only; the normative specification of UIDs and their associated meaning is the responsibility of the coding scheme developer and/or HL7.

  4. The current version of HL7 v2 Table 0396 is available at http://www.hl7.org/special/committees/vocab/table_0396/index.cfm.

  5. The HL7 registration of Coding Schemes is available at http://www.hl7.org/oid/index.cfm.

  6. Publication of codes or references to coding schemes within DICOM does not constitute a grant of intellectual property rights to implementers. Use of some Coding Schemes may require a license, or purchase of the relevant coding scheme publication. Implementers should consult the relevant coding scheme publisher; see also Section 2.

  7. The values of Coding Scheme Name (0008,0115), Coding Scheme Responsible Organization (0008,0116) and Coding Scheme Resources Sequence (0008,0109), if available, may be used to fill the corresponding optional attributes of the Coding Scheme Identification Sequence (0008,0110) in the Section C.12.1 “SOP Common Module” in PS3.3 .

8.1 SNOMED

SNOMED (the Systematized Nomenclature of Medicine) is the preferred coding system within DICOM for anatomy, clinical findings, procedures, pharmaceutical/biologic products (including contrast agents), and other clinical terms.

SNOMED has had various versions, including SNOMED International (Version 3), which was issued in 1993 and revised through 1998, SNOMED Reference Terminology, the successor to SNOMED 3 that was published between 1999 and 2001, and SNOMED Clinical Terms, which has been the name since 2002. The coding scheme is fully backward-compatible across SNOMED 3, SNOMED-RT, and SNOMED CT. SNOMED CT introduced a solely numeric set of codes (ConceptID) in addition to the former alphanumeric codes (SnomedID), but all SNOMED terminology concepts have both a numeric and an alphanumeric code.

In previous editions of the DICOM Standard, the following Coding Scheme Designators were used for SNOMED codes in DICOM:

  • "99SDM", denoting the provisional SNOMED DICOM Microglossary

  • "SNM3", denoting SNOMED International (Version 3)

  • "SRT", originally denoting SNOMED-RT

All uses of SNOMED coded terms in DICOM are now indicated by the Coding Scheme Designator "SRT", identifying them as SNOMED CT terms using the "SNOMED-RT style" alphanumeric code values, with some exceptions:

Consequently, when a Coding Scheme Designator of "99SDM" or "SNM3" is encountered, it shall be treated as equivalent to "SRT" for the purpose of interpreting the Code Value.

Note

"SRT" as a coding scheme designator is used only in the DICOM Standard. HL7v2 did not standardize a coding scheme designator for SNOMED-RT.

When interoperating with systems that use SNOMED CT codes obtained from a source other than the DICOM Standard, Application Entities may receive Code Sequences with a Coding Scheme Designator of "SNOMED-CT" and a numeric ConceptID code. It is the responsibility of such Application Entities to convert any such codes to the alphanumeric SnomedID with Coding Scheme Designator "SRT" for use in DICOM objects and services.

8.1.1 Use of SNOMED Anatomic Concepts

In general, DICOM uses the anatomic concepts with the term "structure", rather than with the term "entire". This is an important distinction in SNOMED. "Entire" is a child concept to "structure", has a more restricted meaning, and typically is used in conjunction with treatments (e.g., "excision of entireright kidney"). It is used in distinction to other sibling children of the parent concept that may identify parts of the parent anatomic feature. Since imaging typically targets both the anatomic feature and the area around it, or sometimes just part of the anatomic feature, DICOM usually uses "structure" concepts that are more inclusive than the "entire" concepts.
