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 September 2020 SNOMED CT United States (US) Edition release includes an updated SNOMED CT to ICD-10-CM mapping reference with over 123,000 SNOMED CT source concepts mapped to ICD-10-CM targets. Please note that no new US-specific concepts were added in this release.
