This dataset, alternatively named in SNOMED CT as “Extended map reference set” enables representation of maps where each SNOMED CT concept may map to one or more codes in a target scheme. It supports the general set of mapping data required to enable a target code to be selected at run-time from a number of alternate codes. It supports target code selection by accommodating the inclusion of machine readable rules and/or human readable advice. Extended map type reference set adds an additional field to allow categorization of maps.
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 410 new concepts specific for the US, the March 2019 SNOMED CT US Edition also contains all of the content from the January 2019 SNOMED CT International Edition. This release includes and updated SNOMED CT to ICD-10-CM mapping reference with over 123,000 SNOMED CT source concepts mapped to ICD-10-CM targets.
