Looks like NDC url is down for FHIR HL7 and we are getting 404 error during validation
Dharma Rajan (Aug 07 2020 at 18:45):
@David Johnson I have sent the email regarding the same
David Johnson (Aug 07 2020 at 18:48):
Dharma, thanks! I've been looking around and chatting internally with @Rob Hausam . The fact is, that right now there is no ndc directory
David Johnson (Aug 07 2020 at 18:48):
I'm trying to find out wy
David Johnson (Aug 07 2020 at 18:48):
why*
David Johnson (Aug 07 2020 at 18:48):
I wasn't sure where the information should be posted. I am very glad you brought it to zulip!
David Johnson (Aug 07 2020 at 18:49):
This is the page that lists the URL: http://hl7.org/fhir/2016sep/ndc.html
David Johnson (Aug 07 2020 at 18:49):
But the link Dharma shared does not exist.
David Johnson (Aug 07 2020 at 18:52):
to be sure, hl7.org/fhir/sid contains the folders
icd-9
icd-10
us-mbi
us-npi
us-ssn
David Johnson (Aug 07 2020 at 18:58):
I see now that this is a terminology section. I may have been chatting with the wrong person... @Ted Klein Do you know if there are any issues?
Dharma Rajan (Aug 07 2020 at 20:01):
We have this one error in our implementation in prod. it worked well 3 weeks back. not sure if anything changed.. We run a risk with validation errors if these urls are not available and FHIR validation fails
Michele Mottini (Aug 07 2020 at 20:09):
Why are you calling the validator in your implementation if I may ask?
Ted Klein (Aug 07 2020 at 20:30):
Not sure exactly what errors you are experiencing. I do know that for the past THREE vocabulary WG conference calls we have had discussions on NDC and the issues around the URL and what it means and validation etc. Decisions were made with consequent changes...Rob Hausam is working on the last remaining details. See the minutes from the past 3 vocabulary WG calls on Confluence the item on NDC11. I hope this helps.
Grahame Grieve (Aug 07 2020 at 21:38):
@David Johnson this should be picked up by the redirects. It was in the past. I'll add it to my list to investigate
Grahame Grieve (Aug 07 2020 at 21:39):
but @Dharma Rajan you should not got a 404 during validation - how are you getting to that point?
Dharma Rajan (Aug 07 2020 at 21:46):
We have a huge JSOn with pharmacy claim data exchange and one of the branches of JSON is NdC
Dharma Rajan (Aug 07 2020 at 21:46):
Dharma Rajan (Aug 07 2020 at 21:47):
U see two errors there ignore the first one.. need to look at the NDC One
Grahame Grieve (Aug 07 2020 at 21:56):
I don't see a 404 there?
Dharma Rajan (Aug 07 2020 at 21:58):
The 404 is coming from that url not in the validator sorry
Grahame Grieve (Aug 07 2020 at 21:59):
ok. thanks. So there is problems with NDC validation right now. @Rob Hausam where are with NDC?
Rob Hausam (Aug 07 2020 at 22:33):
@Dharma Rajan So it looks like there are a couple of issues in the thread. As Ted said, we are actively working out how to handle NDC, including the "official" 10-digit (with dashes) codes and the 11-digit codes that are required for e-prescribing, etc. I'm finishing up with an example of a solution for that, which we should be discussing (and hopefully approving) on the Vocab wG Main call in 2 weeks (8/20). I'm not sure, though, if FHIR build terminology server (tx.fhir.org) or HL7 terminology (terminology.hl7.org) support is critical for your use case? There may be ways to work around that until support is available (I will mention that the HL7 infrastructure will probably never support NDC fully with the nearly "real time", or even monthly, updates). I'm sure we can work out reasonable solution(s), whatever they need to be.
Dharma Rajan (Aug 09 2020 at 15:14):
We tried it without the dashes for the 11 byte prescription NDC and it worked..
Yengibar Manasyan (Aug 12 2020 at 18:35):
Hi everyone,
I see lots of examples where there is a reference that contains only the display field. E.g. Practitioner.identifier.assigner property/reference. In terms of FHIR is it valid data? Does it make sense to have a reference which is not pointing to any resource, instead it contains only display field which has some human-readable info?
Gino Canessa (Aug 12 2020 at 19:11):
Hi Yengibar, the short answer is yes - it is valid FHIR.
The long answer has two parts. The first is the page on references, which describes exactly what is allowed and how things should be interpreted (e.g., a valid display only example). The second is whatever the server you are using implements (e.g., additional business logic that can have different requirements for various scenarios).
Yengibar Manasyan (Aug 12 2020 at 19:14):
Thank you @Gino Canessa !
Gino Canessa (Aug 12 2020 at 19:16):
No problem!
