SNOMED CT Delta Description
The Description file holds descriptions that describe SNOMED CT concepts. A description is used to give meaning to a concept and provide well-understood and standard ways of referring to a concept. This dataset describes the Release File structure of SNOMED CT, referred to as Release Format 2 (RF2). The US Edition of SNOMED CT is the official source of SNOMED CT for use in US healthcare systems.

Description
SNOMED CT (SNOMED Clinical Terminology) provides a common language that assists with the electronic exchange of clinical health information. It enables a consistent way of indexing, storing, retrieving, and aggregating clinical data across specialties and sites of care. SNOMED CT Can be mapped to other coding systems, such as ICD-10, which helps facilitate semantic interoperability.
A Delta release contains only those component versions created, inactivated or changed since the previous release. The ‘Delta’ release is much smaller than a ‘Full’ release and is ideal for updating a ‘Full’ release of the previous version. Adding a ‘Delta’ release to the previous version’s ‘Full’ release will update the installation to a ‘Full’ release of the current Version.
The SNOMED CT dataset enhances semantic interoperability in healthcare, which can complement applications of Generative AI in healthcare by improving clinical data exchange and coding accuracy.

Data Fields
Name | Description | Type | Constraints |
---|---|---|---|
Description_Id | Uniquely identifies the description. | integer | level : Nominalrequired : 1 |
Effective_Date | Specifies the inclusive date at which the component version's state became the then current valid state of the component | date | required : 1 |
Is_Active | Specifies whether the concept's state was active or inactive from the nominal release date specified by the Effective_Date | boolean | required : 1 |
Module_Id | Identifies the description version's module. | integer | level : Nominalrequired : 1 |
Concept_Id | Identifies the concept to which this description belongs. Note that versions of descriptions and concepts don't belong to each other. Which version of any given description is combined with which version of its owning concept depends on the point in time at which they are accessed. | integer | level : Nominalrequired : 1 |
Language_Code | Specifies the language of the description text using the two character ISO -639-1 code. Note that this specifies a language level only, not a dialect or country code. | string | required : 1 |
Type_Id | Identifies whether the description is an FSN, Synonym or other description type. | integer | level : Nominalrequired : 1 |
Term | The description version's text value. | string | - |
Case_Significance_Id | Identifies the concept enumeration value that represents the case significance of this description version. For example, the term may be completely case sensitive, case insensitive or initial letter case insensitive. | integer | level : Nominalrequired : 1 |
