2source title(+)0;3FREE TEXTFull title of source. Also includes edition/revision and year of publication when available.
3source0;4FREE TEXTThis is source of the named coding system.
4entries0;5NUMERICThis is the number of coded entries found in the Lexicon (by classification system) at the time of export. NOTE: This does not include deactivated entries.
5unique entries0;6NUMERICThis is the number of unique coded entries found in the Lexicon (by classification system) at the time of export. NOTE: This does not include deactivated entries.
6inactive version0;7FREE TEXTThis represents the version number of the source file for which inactivated codes are derived.
7hl7 coding system0;8FREE TEXTDThis is the HL7 coding system mnemonic for the Lexicon coding system
10sdo version1;0MULTIPLE757.08This multiple stores the Standards Development Organization's (SDO) nomenclature that identifies the versions of their code systems and their associated dates. This information will be essential to applications that share code systems data with external agencies.
11implementation date2;1DATE-TIMEThis is either the VistA implementation date or the initial publication date. If the VistA implementation date is different from the initial publication date then the VistA date will be used, i.e. ICD-10 Published (world wide) Jan 1, 1992 ICD-10 VistA Implementation Oct 1, 2013 Oct 1, 2013 is used for ICD-10 UMDNS Published (world-wide) Jan 1, 1993 UMDNS VistA Implementation N/A Jan 1, 1993 is used for UMDNS
