The SNOMED CT to ICD-10 map is released on January 31 and July 31 as a derivative of the SNOMED CT International Release. This map is a directed set of associations from SNOMED CT source concepts to ICD-10 target classification terms. The SNOMED CT source domains for the map are limited to subtypes of 404684003 |clinical finding|, 272379006 |event| and 243796009 |situation with explicit context|.
As of the July 31 2015 release, all SNOMED CT concepts in scope have been mapped. An algorithmic approach was used in the completion of the map. Algorithms have been incorporated into the mapping tool for the July 31 2016 release. SNOMED International welcomes the opportunity to work with organizations or institutions who are interested in undertaking usage validation of the SNOMED CT to ICD-10 map. Please contact firstname.lastname@example.org for more information.
SNOMED International also publishes a map between the SNOMED CT International General/Family Practice subset (GP/FP subset) and the International Classification of Primary Care, 2nd Edition (ICPC-2). The GP/FP subset focuses on two semantic data types commonly used in general/family practice electronic health records: Reasons For Encounter (RFEs) and Health Issues.
The SNOMED CT to ICD-9-CM Epidemiological and Statistical Map was deprecated with support effective 31 January 2016 and without support effective July 31 2016. SNOMED International recognizes that some Members and Affiliates continue to use ICD-9-CM. It is important to note that the SNOMED CT to ICD-9-CM Epidemiological and Statistical Map will continue to be available after the deprecation on the SNOMED International Confluence site to any users who wish to access it during their transition to SNOMED CT or ICD-10-CM.
The SNOMED CT to ICD-O maps are released as a simple map reference set in the SNOMED CT International Release. The SNOMED CT source domains for the maps are limited to subtypes of 400177003|Neoplasm and/or hamartoma (morphologic abnormality)| and 91723000|Anatomical structure (body structure)| for ICD-O morphological codes and Topographical codes.
