Complexity

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.

In addition to 623 new concepts specific for the US, the September 2018 SNOMED CT US Edition also contains all of the content from the July 2018 SNOMED CT International Edition. Approximately 543 requests for terminology additions and updates were submitted via the US Content Request System (US CRS) to support US clinical health information data exchange. This latest version of the US Edition also includes the SNOMED CT to ICD-10-CM reference set, with over 123,000 SNOMED CT source concepts mapped to ICD-10-CM targets.
