Comments:

Looks like this WG is not using Jira, so I'll copy, and extend my comment from Issue PA-2 into here:-

1. The code used at Prescriber Number purports to borrow from AS4700.3, but instead incorrectly ( it seems )  invents a code 'PRESC'.
2. HL7 V2 table 0203 does not have a specific code for prescriber number.
3. HB234-2012 mentions an extension code 'PRES',  also cited in AS4700.3-2014 page 55. The latter also cites codes 'PHARM' and 'SELFPRESC'.
4. AS4700.3-2014 does not specify any codes for Prescriber Number Identifier Type.
5. Neither 'PRES' nor 'PRESC' has been registered with HL7 as a valid code in Table 0203. Neither have codes 'PHARM' nor 'SELFPRESC'.
6. This issue demonstrates inadequate governance and provenance of Australian healthcare vocabularies.

7. HL7v2  XCN datatype supports both an Identifier Type code ( from Table 0203 ) and an Assigning Authority, which together can differentiate Provider Identifier namespaces.

8. Thus, prescriber number in V2 could be represented by Identifier Type Code of 'PRN' with Assigning Authority of 'AUSPBS'. Otherwise, a  specific prescriber number code should be registered in V2 table 0203.

Thanks for the comments/references Eric, I'm looking into where these values came from now to ensure we get it right.

And yes, I can see the PRES, SELFPRESC parts on the AS4700.3 that you refer to.

Thanks Eric that is a typo.... twice copied... 

The url is also not an existing agreed one so have changed that also - we are going to discuss namespacing for that at next TC for PA

This is not a table 0203 code as you say... so think your suggestion in #8 is a good one... 

We are using the namespace http://hl7.org.au/v2/0203 as Australian table 0203 localisations these are sourced from AS4700.x published standards  - currently this does not associate with anything useful like. http://www.hl7.org/fhir/dstu2/v2/0203/index.html does.  The aim is to do so... 

This will go on the agenda for next PA TC also...
