The database table will have to be done by Karsten. 
I could have a try at implementing some browser widget.

I am not sure about the complexity yet. There is more then meets the eye.
There is storing one or more codes and there is assigning one or more codes.

Assining involves picking it from some code browser. You could help by 
thinking about a workflow and maybe find existing ideas and collect what you 
like or dislike.

The hard part will be to support multiple coding systems per se, multiple 
codes per health issue, multiple versions within a coding system and multiple 
languages per one coding system.

So we have at least
OPS for procedures
ICD 9 and ICD 10
we have ICD 10 WHO and e.g. ICD 10 GM (Germany)
and we have ICD-10 GM 2009 and ICD-10 2010 and ICD-10 2011

It takes an database wizard to get this done.

Then there is the code browser part. One could/should start simple and go from 
there. Initially we could preselect the coding system per doctor. this has 
nothing to do with the storing part in the database. This is about getting the 
code you are looking for from a list of codes.

Later this code browser could/should support multiple coding systems and 
return matches from more then one source. Even later it could find related 

This brings up the issue of the source. How is the source stored for easy 
access ?

ICD10 GM 2010 is provide as ASCII or XML or pdf and a few more. There is at 
least one commercial product which makes use of the XML directly. Other option 
would be to import the sources (e.g. ICD9, 10) into special database tables 
and retrieve them from there.

Is there any know advantage for either using XML directly or first storing it 
into database tables. How are the other sources (e.g. ICD10 WHO) provided ?

How to handle (offical) translations ?

Anyone with experience on this should speak up and save us a lot of time.
