Mapping Systematized Nomenclature of Medicine–Clinical Terms (SNOMED CT) to International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM): Lessons Learned from Applying the National Library of Medicine’s Mappings
The Systematized Nomenclature of Medicine–Clinical Terms (SNOMED CT) and the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) are two commonly used standardized health terminologies in the United States. In fall 2015, healthcare facilities across the United States were required to transition to a newer and more detailed version of one of these terminologies, from ICD-9-CM to ICD-10-CM. To facilitate the terminology transition, the National Library of Medicine (NLM) released semi-automated mapping rules and guidelines that should enable translation between SNOMED CT and ICD-10-CM codes.
