SNOMED CT: New US Edition and Final US Extension Available. NLM Tech Bull. 2013 Mar-Apr;(391):b1.
US Edition of SNOMED CT®
The release of the US Edition of SNOMED CT is now available. The US Edition combines the International Release of SNOMED CT and US-specific content previously found in the US Extension to SNOMED CT. It eliminates the need for users to combine the two products. The US Edition is the official source of SNOMED CT for use in US healthcare systems.
The download contains files in both Release Format 1 (RF1) and Release Format 2 (RF2) versions. NLM will provide an updated US Edition approximately one month after each International Release update.
US Extension to SNOMED CT Final Release
NLM will no longer provide a separate US Extension to SNOMED CT file. The final release of the US Extension is available for download from the same page as the US Edition.
