US Edition of SNOMED CT(R): September 2015 Release Introduction The US Edition of SNOMED CT is a combination of the full SNOMED CT International Release and the US Extension to SNOMED CT. The US Edition eliminates the need for implementers to manually combine the US Extension and the International Release.

The US Edition of SNOMED CT is not software. NLM performs quality assurance checks to ensure that US Edition data fully conforms to both RF1 and RF2 specifications. File description Edition files are designed as tab-delimited text files to be used as relational tables with each line in the file representing a row in the table. The first row of each table contains column headings. All other rows contain data. The Septmber 2015 US Edition is distributed in both RF1 and RF2 formats in two separate zip file: SnomedCT_RF1Release_US1000124_20150901.zip (156 MB) and SnomedCT_RF2Release_US1000124_20150901.zip (459 MB). Edition Files contain US Extension specific content and the full International release content providing a comprehensive compilation of the content from both sources. US Edition releases in both RF1 and RF2 contain files that correspond to SNOMED CT files and are described in the "SNOMED CT(R) Technical Implementation Guide, International Release." The Guide is part of the SNOMED CT download package available from the UMLS Terminology Services (UTS) at https://uts.nlm.nih.gov. and is also searchable on the IHTSDO SNOMED CT Documentation page.
