Topic: CVX and NDC warnings in US Core
Eric Haas (Dec 01 2020 at 05:45):
WE have these code validation errors with both CVX and NDC.
WARNING: Immunization/imm-1: Immunization.vaccineCode.coding[0]: Internal error: Unknown Code http://hl7.org/fhir/sid/cvx#158 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
ERROR: Immunization/imm-1: Immunization.vaccineCode.coding[1]: The code "49281-0633-15" is not valid in the system http://hl7.org/fhir/sid/ndc; The code provided (http://hl7.org/fhir/sid/ndc#49281-0633-15) is not valid in the value set 'All codes known to the system' (from http://tx.fhir.org/r4) for 'http://hl7.org/fhir/sid/ndc#49281-0633-15'
The CVX code 158 does indeed exist in the vsac valueset we reference ( see the VSAC Warnings stream for how that is working for us) and I confirmed the system here
The NDC code also was copied from the cdc source here: http://www2a.cdc.gov/vaccines/iis/iisstandards/ndc_crosswalk.asp as per our guidance in US Core.
Is there something we are missing?
Grahame Grieve (Dec 01 2020 at 05:57):
did you try clearing the tx cache?
Eric Haas (Dec 01 2020 at 06:16):
not building locally -using the autobuild
Grahame Grieve (Dec 01 2020 at 07:17):
doesn't change my answer
Grahame Grieve (Dec 01 2020 at 07:18):
no wonder people are complaining about build times
Eric Haas (Dec 01 2020 at 18:10):
I am unable to build locally for a couple of reasons: 1) the vsac package causes a memory error. ( leak ?) 2) It slows my local machine to a crawl as discussed elsewhere.
Eric Haas (Dec 01 2020 at 18:11):
...and it takes forever
Eric Haas (Dec 01 2020 at 18:35):
OK I updated my local build to 4G, cleared all packages and local cache, and after 20 minutes these errors still there.
Grahame Grieve (Dec 02 2020 at 03:48):
@Ted Klein it would appear that the source of the cvx problem is UTG. There's a code system sourceOfTruth/external/v2/codeSystems/cs-v2-0292.xml which is a out-of-date? representation of a portion of CVX, but this is being loaded by the terminology server over the top of it's interal master representation which does contain code 158. What is this bad code system doing existing?
Grahame Grieve (Dec 02 2020 at 03:50):
as for 49281-0633-15 - it's not the NDC source as far as I can tell.
Eric Haas (Dec 02 2020 at 15:55):
The CDC has published this NDC To CVX mapping here: that was my source: : http://www2a.cdc.gov/vaccines/iis/iisstandards/ndc_crosswalk.asp

@Craig Newman can you comment more on the veracity of this table and the ndc codes?
Craig Newman (Dec 02 2020 at 17:41):
@Eric Haas That is the official CDC mapping table. If there is an NDC code in there, it should be valid. There are separate "unit of sale" and "unit of use" NDCs (the NDCs on the box and on the vial/syringe respectively) but both of them should be valid.
Grahame Grieve (Dec 02 2020 at 19:36):
@Rob Hausam ?
Rob Hausam (Dec 02 2020 at 20:33):
These are on the list to add/update. We do need to think about the update schedule for NDC. Those updates are available monthly (or more frequently) - not sure if we expect to try to keep up with that, or if a lesser frequency is sufficient?
Grahame Grieve (Dec 02 2020 at 20:34):
not sure to that but we can bring it up to date now?
Eric Haas (Dec 10 2020 at 00:29):
@Rob Hausam where are we with this?
Eric Haas (Feb 20 2021 at 03:10):
The error for the NDC code now seems fixed, thanks @RobHausam however, the following warning that the cvx code is unknown still persists. Indeed based on the CDC web site the code does exists :
Immunization/imm-1: Immunization.vaccineCode.coding[0] (l22/c11) warning Unknown Code http://hl7.org/fhir/sid/cvx#158 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#158'
Grahame Grieve (Feb 24 2021 at 03:27):
how do I reproduce this?
Eric Haas (Jun 09 2021 at 02:11):
OK - now we are back to having the NDC error ( the CVS warning is gone ) see: http://build.fhir.org/ig/HL7/US-Core/qa.html @Rob Hausam ?
Rob Hausam (Jun 09 2021 at 02:31):
@Eric Haas It wouldn't be at all surprising if the NDC issue is due to an outdated NDC version on the server - currently it's on 20190321. And since the '49281-0633-15' code in your example shows the (earliest) "Start Marketing Date" as 07-02-2020, that would certainly be sufficient reason for the error. So NDC needs an update - it's on the list.
Eric Haas (Jun 23 2021 at 23:06):
Hey @Rob Hausam is there an eta on updating NDC codes (or just adding just this one)?
Rob Hausam (Jun 23 2021 at 23:17):
Grahame has been working on the properties, but I think that may not be complete yet - right now I'm getting an OperationOutcome when I try to do a code $lookup. And I think the NDC content still needs to be updated to the current version - but right now my remote desktop access to the tx.fhir.org server also isn't working. I'll try to give you a more complete update soon.
Grahame Grieve (Jun 23 2021 at 23:18):
what's the operation outcome about? I thought it all good now
Rob Hausam (Jun 23 2021 at 23:19):
{
"resourceType" : "OperationOutcome",
"text" : {
"status" : "generated",
"div" : "<div xmlns=\"http://www.w3.org/1999/xhtml\"><p>Identifier Suffix not found in result set.</p></div>"
},
"issue" : [
{
"severity" : "error",
"code" : "invalid",
"diagnostics" : "Identifier Suffix not found in result set."
}
]
}
Rob Hausam (Jun 23 2021 at 23:20):
the query was http://tx.fhir.org/r4/CodeSystem/$lookup?system=http://hl7.org/fhir/sid/ndc&code=00409371801
Rob Hausam (Jun 23 2021 at 23:25):
I can remote into the server now - the NDC content still needs to be updated. And I should be able to do that at any time (but won't do that yet if Grahame is still working on it).
Grahame Grieve (Jun 23 2021 at 23:26):
no please update it
Rob Hausam (Jun 23 2021 at 23:32):
ok
Rob Hausam (Jun 30 2021 at 21:06):
The NDC content has been updated to be current as of 2021-06-27. @Eric Haas
