SNOMED CT Snapshot Description
This dataset holds descriptions that describe SNOMED CT concepts. A description gives 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) which is the official source of SNOMED CT for use in US healthcare systems. The US Edition is a standalone release that combines the content of both the US Extension and the International release of SNOMED CT.

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 Snapshot release contains the most recent version of every component released up to the time of the snapshot. The version of each component contained in a snapshot is the most recent version of that component at the release time. The ‘Snapshot’ release is useful for a simple installation but does not provide a history or retrospective view of the terminology. There are valid use cases for each Release Type. Each International release will incorporate all three of these Release Types, allowing users to choose the most appropriate format.
The March 2020 release contains relevant COVID-19 concepts including any applicable changes to descriptions. With this interim release, 24 records have been added, plus core concept descriptions added back in referencing March 2020.
With this release, clinicians, researchers and administrators globally are able to code, analyze and plan to address the Coronavirus effort with the most up to date terminology.

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 | - |
Is_Active | Specifies whether the concept's state was active or inactive from the nominal release date specified by the Effective_Date | boolean | - |
Module_Id | Identifies the description version's module. | integer | level : Nominal |
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 : Nominal |
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 | - |
