You can download both the SNOMED CT International Release and the SNOMED CT US Edition, as well as other SNOMED CT-related release files such as subsets and mapping files, through the NLM UMLS Terminology Services (UTS). You may also use the UMLS SNOMED CT Browser to search for and display SNOMED CT content, as included in the UMLS Metathesaurus. The search mechanism uses UMLS data and tools to enhance the retrieval. A UMLS License is required to access and download SNOMED CT and to use the UMLS SNOMED CT Browser.
