Australian Extensions to HL7 v2 table 0396

Dec 7, 2011

HL7 v2 table 0396 is the list of known coding systems in HL7 v2. The table is very US centric, and most of the main Australian coding systems are not found in the HL7 international table 0396. Through the IT-14 sub-committees, HL7 Australia has long had the practice of extending this table, but there has been no systematic approach to doing so. We need a single list that gathers everything that is used together. Note: The table below contains candidate mappings that need review, and the review will be done on the HL7 Australia wiki here: http://hl7-australia.wikispaces.com/Australian+Extensions+to+HL7+v2+table+0396 - see here for the updated copy.

The code goes in CE.3 or CE.6 (or CNE.3/CNE.6/CWE.3/CWE.6/CWE.12) to identify the code system. The code is the only valid way to represent the code system.

Note: Some users are using variations ( AMT-MP??

Extending this list

Under the rules of the coding system, you can’t extend this list on a site specific basis (actually, we - HL7 Australia - are not really supposed to extend this list either). If you have your own local coding system, you have to use some code beginning with L to indicate the code system. I don’t know whether there’s any interest or point in defining a method for generating unique values in that space or not.
