Topic: CVX code system
Max Masnick (Apr 21 2021 at 21:47):
@Grahame Grieve I believe you said CVX is fixed, but our value set expansion is still not working as far as I can tell?
- Here's the value set: http://build.fhir.org/ig/dvci/vaccine-credential-ig/branches/cvx-code-system/ValueSet-vaccination-credential-vaccine-value-set.html
- The underlying FSH is
* include codes from system http://hl7.org/fhir/sid/cvx - The branch is here if you want to clone locally: https://github.com/dvci/vaccine-credential-ig/tree/cvx-code-system
Expected behavior: 207 is the CVX code for the Moderna vaccine, but it's not included in the value set expansion. More generally all the codes listed here should be in the value set expansion.
What actually happens: none of the COVID codes are present in the value set expansion, or in the code systems linked here: image.png

sigh. Stinking UTG has multiple bunkum representations of CVX and I missed somewhere in the code where I ignore the UTG ones; I've put in a harder override specifically for CVX for now. Next release you'll get this:

Awesome, thanks! BTW I’ve opened a Jira issue with Vocab to try to do something about the multiple out of date CVX representations.
Grahame Grieve (Apr 21 2021 at 23:10):
it's already on their radar but more pressure is good ;-)

we believe that the current cvx content on tx.fhir.org is correct
Max Masnick (Apr 22 2021 at 14:14):
@Grahame Grieve along the lines of getting CVX updated to include the COVID-related vaccines, can MVX be updated to have the COVID vaccine manufacturers (like JSN, MOD, and ASZ)?
Here's our attempt to get an expansion of the PHIN VADS value set for MVX: http://build.fhir.org/ig/dvci/vaccine-credential-ig/branches/terminology-improvements/ValueSet-vaccination-credential-vaccine-manufacturer-value-set.html

What's the request I would need to make manually with curl (or similar) to see what tx.fhir.org has for CVX codes?
Paul Denning (Apr 22 2021 at 14:37):
curl http://tx.fhir.org/r4/CodeSystem/cvx?_format=json
(or similar, I like https://github.com/tomnomnom/gron)
gron http://tx.fhir.org/r4/CodeSystem/cvx?_format=json | grep COVID
Max Masnick (Apr 22 2021 at 20:46):
Thanks! I can confirm the COVID CVX codes are on tx.fhir.org now!

@Grahame Grieve @Mark Iantorno I'm still seeing a spurious warning related to invalid CVX codes with the FHIR Validation tool Version 5.3.11 (Git# 33fffe28ff6b). Built 2021-04-22T05:48:36.375Z (6 days old):
Warning @ Bundle.entry[1].resource.ofType(Immunization).vaccineCode.coding[0] (line 32, col14) : Unknown Code http://hl7.org/fhir/sid/cvx#207 in http://hl7.org/fhir/sid/cvx - note that the code system is labelled as a fragment, so the code may be valid in some other fragment for 'http://hl7.org/fhir/sid/cvx#207'
The portion of the resource in question:
"vaccineCode": {
"coding": [
{
"system": "http://hl7.org/fhir/sid/cvx",
"code": "207"
}
]
},
And 207 is part of the expansion now (thank you!!!).
So I don't see anything wrong with the IG or the example resource that would be causing this warning.
Can you please take a look?
Steps to reproduce:

sigh. Some old voca b managed content has a bad copy of the cvx code system. I just found yet another place where I have to specifically instruct the terminology code to ignore the bad copy of cvx. So this will be fixed next time the validator is released
Max Masnick (Apr 29 2021 at 21:15):
Thank you for persevering through this.
