Topic: ATC Level 1
Michaela Ziegler (Mar 30 2020 at 13:49):
Can anyone explain to me why the ATC Level 1 code is not valid? We have an use case in which we would like to categorize according to this level 1.
<coding>
<system value="http://www.whocc.no/atc"/>
<code value="C"/>
</coding>
error: The code "C" is not valid in the system http://www.whocc.no/atc; The code provided (http://www.whocc.no/atc#C) is not valid in the value set All codes known to the system für "http://www.whocc.no/atc#C"

Because it's not listed in the code system in the validator source, which is https://github.com/FHIR/packages/blob/master/packages/fhir.tx.support.r4/package/CodeSystem-atc.json. @Rob Hausam I'm not sure what the history of that file is - is there an authoritative source?
Rob Hausam (Mar 30 2020 at 23:05):
The history is that, because there wasn't (at least at the time that it was added) a readily identifiable and accessible comprehensive source for the entire code system, the code system resource to support ATC was added for tx.fhir.org with only a small selection of concepts included, which were the ones that had a known need at the time - specifically for the IPS IG. Any additional valid ATC codes can be added to that at any time, as needed for any IG or other use case. We just need to know which concepts are needed - obviously 'C' is one that is, but there may be others? The best alternative would be if someone is able to provide or we (as in FHIR) are otherwise able to negotiate obtaining an authoritative source for the entire ATC code system that we can load and host (with the licensing considerations properly met). @Michaela Ziegler @Grahame Grieve

Thanks for the information! For our eMedication project/IG we would need the following codes, which are not yet included in the CodeSystem:
A Alimentary tract and metabolism
B Blood and blood forming organs
C Cardiovascular system
D Dermatologicals
G Genito-urinary system and sex hormones
H Systemic hormonal preparations, excluding sex hormones and insulins
J Antiinfectives for systemic use
L Antineoplastic and immunomodulating agents
M Musculo-skeletal system
N Nervous system
P Antiparasitic products, insecticides and repellents
R Respiratory system
S Sensory organs
V Various
@Rob Hausam What would be the procedure for me now to add these additional ATC codes?
Rob Hausam (Mar 31 2020 at 19:18):
@Michaela Ziegler I think you've already done it. :) You need to let me know which ATC codes you would like to have added - and I'm assuming that's the list that you just posted. I do want to clarify that you only need to have those particular top-level codes, and none of the more specific codes beneath them? If that's the case, then it shouldn't be a problem to add them (I will verify the display strings, etc. with the WHO ATC browser - for the exact capitalization, etc.). As I mentioned before, if you or anyone else is aware of a comprehensive source that is or can be made available (with proper licensing) for adding the full ATC code system, that would be better. But in the absence of that we can proceed this way.
Michaela Ziegler (Apr 01 2020 at 13:30):
@Rob Hausam Thanks, that's great! Exactly, the codes are those on the list. It is only the special Top Level Codes that we need. Unfortunately I cannot help with the comprehensive source (licensing), we also get the codes from the WHO ATC browser.
Rob Hausam (Apr 21 2020 at 17:02):
An update - this is almost there. I've added the new contents to the package repository. But there's another step needed to get the content published on the terminology server that I need to look at with Grahame.
Michaela Ziegler (May 07 2020 at 12:31):
@Rob Hausam Thank you very much for adding the values. Are there any updates on the terminology server yet?
