To support browsing and understandability of the MAP, a tab delimited UTF-8 dataset which can be imported into spreadsheet software such as Microsoft Excel® is included with the release. This can be loaded with the text import features of Excel and most spreadsheets. The spreadsheet data format mimics the exemplar appendices of the technical documentation and is a “readable” version of the map that can be understood by a non-technical individual.
SNOMED CT is an extensive clinical terminology that was formed by the merger, expansion, and restructuring of SNOMED RT (Reference Terminology) and the United Kingdom National Health Service (NHS) Clinical Terms (also known as the Read Codes). It is the most comprehensive clinical vocabulary available in English (or any language). SNOMED CT is concept-oriented and has an advanced structure that meets most accepted criteria for a well-formed, machine-readable terminology. It has been designated as a US standard for electronic health information exchange in Interoperability Specifications produced by the Healthcare Information Technology Standards Panel and has also been adopted for use by the US Federal Government, through the Consolidated Health Informatics (CHI) Initiative, for several clinical domains.
This cross map is a directed set of relationships from SNOMED CT source concepts to ICD-10-CM target classification codes. The SNOMED CT source domains for this mapping are limited to subtypes of 404684003 |clinical findings|, 272379006 |event| and 243796009 |situation with explicit context|.
This update of the map includes:
– 100,185 SNOMED CT source concepts including:
– 94,844 clinical findings
– 2,813 events
– 2,528 situations with explicit context
– 5,696 source concepts could not be assigned a map target due to issues of ambiguity or target scope
– A total of 168,810 map records, with a maximum of 23 map records per map group
