ICD-9-CM to SNOMED CT Map. NLM Tech Bull. 2012 May-Jun;(386):b3.
The new ICD-9-CM to SNOMED CT Map is available for download by UMLS licensees. The map will facilitate the translation of legacy ICD-9-CM data to SNOMED CT and aid the transition to use of SNOMED CT for patient problem lists. The download consists of two files (one-to-one maps and one-to-many maps), which include usage frequencies of ICD-9-CM codes based on CMS (Centers for Medicare & Medicaid Services) data, and SNOMED CT concepts from the CORE Problem List Subset.
