Topic: Proper System for ICD-9?
Jean Duteau (Jul 21 2019 at 06:53):
When I change it to http://hl7.org/fhir/sid/icd-9, I no longer get that error, but I still get the "URL value: 'http://hl7.org/fhir/sid/icd-9' does not resolve" error.
Rob Hausam (Jul 21 2019 at 14:14):
Changed the url from what? The terminology service (tx.fhir.org) doesn't currently have explicit support for any ICD-9 variants (including the "plain" ICD-9 from WHO or the US ICD-9-CM). The only url in the base spec that we've defined and listed for ICD-9 is http://hl7.org/fhir/sid/icd-9-cm for the US (on the Using ICD-[X] Codes with FHIR page) - and it doesn't actually resolve to anything useful for the code system, but in the browser ends up redirecting to the terminologies-systems page. And we do have a rather general url "does not resolve" issue that Grahame is aware of and intends to fix (and I'm looking at on the terminology service side).
Rob Hausam (Jul 21 2019 at 14:27):
Since most of the world (including now the US) has moved on to ICD-10, I expect we felt that we didn't need to expend effort at this point to add support for ICD-9. @Jean Duteau, do you have particular items in mind (ICD-9, ICD-9-CM or others) that you think should be supported by the terminology service and validator?
Jean Duteau (Jul 21 2019 at 17:10):
Sorry, but part 1 of my question went in a different stream. I am doing some Da Vinci work and all of their examples use ICD-9 for the diagnosis codes. I've changed the example to use http://hl7.org/fhir/sid/icd-9 to get rid of one error as icd-9-cm gives me two. :)
Grahame Grieve (Jul 21 2019 at 21:16):
what are the errors? Are you making something wrong in an example to hide a bug in the validator framework?
Jean Duteau (Jul 21 2019 at 21:32):
With icd-9-cm as the code system, I get the following two errors:
Unknown Code System http://hl7.org/fhir/sid/icd-9-cm
URL value 'http://hl7.org/fhir/sid/icd-9-cm' does not resolve
With just icd-9, I only get the 2nd error:
URL value 'http://hl7.org/fhir/sid/icd-9' does not resolve
Rob Hausam (Jul 21 2019 at 21:46):
So what would you like to be getting (obviously not the "does not resolve" error)? How do you want/need to use ICD-9, in which variant(s)?
Jean Duteau (Jul 21 2019 at 21:48):
well, it would be nice
a) to know which is the official URL because icd-9-cm is listed in the spec but that gets the unknown code system
b) not get the "does not resolve" error
c) ensure the codes I'm using don't error out either
I don't need full support for icd-9-cm at this time, I'm just trying to show how existing X12 messages would be converted into FHIR operations without any translation at this time.
Rob Hausam (Jul 21 2019 at 21:57):
If you can send me the ICD-9-CM codes that you are using in your examples then I should be able to get them added so the terminology server will support them.
Jean Duteau (Jul 21 2019 at 22:02):
183.0, 263.0,410.90
Rob Hausam (Jul 21 2019 at 22:05):
OK, that shouldn't be hard. I'll take a look at it and I should be able to get the support added and get back to you shortly.
Jean Duteau (Jul 21 2019 at 22:05):
thx
Grahame Grieve (Jul 22 2019 at 10:39):
it won't be an error after the next release. I don't know when that will be - depends on where I can get decent enough bandwidth to do a release (won't be here - at the birthplace of "Waltzing Matilda" today - famous Australian song)
Eric Haas (Oct 16 2019 at 20:06):
I too am getting this qa error for US Core Problem Value Set
URL value 'http://hl7.org/fhir/sid/icd-9-cm' does not resolve
I stuck it in ig.json as a "special-urls" but am still getting this error? @Grahame Grieve ?
"special-urls": [
"urn:oid:2.16.840.1.113883.6.238",

],
Grahame Grieve (Oct 17 2019 at 21:40):
special urls won't fix that error
Grahame Grieve (Oct 17 2019 at 21:40):
I've added it too my list (which is still growing faster than I can keep up with)
Eric Haas (Oct 17 2019 at 21:46):
ty and understand the list thing
Grahame Grieve (Oct 17 2019 at 22:17):
well, I just knocked a big task off my list... 12 hours for regenerating... just need to get this technical correction out and I'll be much happier
Grahame Grieve (Oct 24 2019 at 22:00):
how do I reproduce this?
Eric Haas (Oct 25 2019 at 00:01):
current build for US Core - see condition.code valueset.
Grahame Grieve (Oct 25 2019 at 00:28):
fixed next release
Lloyd McKenzie (Apr 25 2020 at 19:21):
I'm getting this error using the most recent version of the publisher:
Unknown Code System "http://hl7.org/fhir/sid/icd-9-cm"
Grahame Grieve (Apr 25 2020 at 19:49):
https://chat.fhir.org/#narrow/stream/179202-terminology/topic/ICD-10-PCS
Lloyd McKenzie (Apr 25 2020 at 19:51):
@Grahame Grieve I looked in that thread and I didn't see any obvious answers. I don't want ICD-10, I want ICD-10. icd-9-cm is listed as the correct URL in the CI build. Should I be using something else instead?
Jean Duteau (Apr 25 2020 at 19:52):
I've been using icd-9-cm and getting the same error, so I just assumed that the terminology server didn't have ICD-9 loaded
Grahame Grieve (Apr 25 2020 at 19:52):
I don't believe we've defined a URL for icd-9-cm
Jean Duteau (Apr 25 2020 at 19:53):
http://hl7.org/fhir/icd.html lists http://hl7.org/fhir/sid/icd-9-cm as the System
Grahame Grieve (Apr 25 2020 at 19:55):
hmm I did not read it correctly. I don't know what we would use for normal icd-9. presumably http://hl7.org/fhir/sid/icd-9. though i don't know if anyone is still using that
Grahame Grieve (Apr 25 2020 at 19:55):
if someone comes up with licensed content for icd-9-cm, I'll be happy to load it on the terminology server
Lloyd McKenzie (Apr 25 2020 at 20:06):
I'm not looking for the content to be loaded, but it would be nice if it didn't yell and say that the code system was unknown when we publish it as the approved 'system'. (Saying it doesn't have any knowledge of the codes to verify them would be totally fine.)
Grahame Grieve (Apr 25 2020 at 20:06):
where does it say that it's unknown?
Jean Duteau (Apr 25 2020 at 20:08):
actually, @Lloyd McKenzie , I don't get that error, I get the "Unable to provide support for code system http://hl7.org/fhir/sid/icd-9-cm" warning/error.
Lloyd McKenzie (Apr 25 2020 at 20:09):
Bundle/pcde-document: Bundle.entry[9].resource.ofType(Condition).code.coding[0] (l325/c19) error Unknown Code System "http://hl7.org/fhir/sid/icd-9-cm"
Lloyd McKenzie (Apr 25 2020 at 20:12):
Was an issue 8 months ago and remains one. The CI build for PCDE currently there won't build - needs the US Core dependency updated to 3.1.0. Will be pushing an update tomorrow that fixes that and makes a bunch of other changes. If you want to test now, just change the version dependency in the IG.
Grahame Grieve (Apr 25 2020 at 20:16):
can you make a validator test case for icd-9=cm?
Peter Jordan (Apr 25 2020 at 21:24):
Different version of ICD, but I know that @Reuben Daniels is attempting to get a URL for ICD-10-AM.
In the interim, I've had to use an NZ MoH based URL as my server treats any conformance resource URL beginning with http://hl7.org/fhir/ as an HL7 hosted resource and attempts to get that resource from http://tx.fhir.org/r4
Rob Hausam (Apr 25 2020 at 21:30):
I was recently looking at loading icd-9-cm (at least some example content) on tx.fhir.org, but I'm not sure that loading icd-9[x] is supported by the server. I hadn't asked you about that yet @Grahame Grieve or checked the code to verify.
Rob Hausam (Apr 25 2020 at 21:35):
We do support multiple variants of ICD-10, but not (yet) ICD-11 and. as I said, I'm not certain about the capability presently to support ICD-9. We probably need it, as ICD-9[x] is definitely still used in some jurisdictions (and potentially in historical data).
Grahame Grieve (Apr 25 2020 at 21:35):
icd-9 is small enough that we should just load it from a code system resource
Rob Hausam (Apr 25 2020 at 21:45):
Yes, that makes sense. We still have the typical issue with ICD of not having a readily available source for the entire code system (typically the most important billable leaf codes with the final digits specified are missing from the enumerated list in the freely available source). But using a CodeSystem resource we can at any time upload a code system fragment containing the subset of codes that people need support for (in IG examples, etc.). Once that content is created there are some additional steps in getting it actually loaded and available on the server, so it likely won't appear immediately, but it's not difficult and shouldn't take too long for it to be accessible.
Jean Duteau (Apr 25 2020 at 23:08):
I have some codes that I'll need, so I can ping you those when you're ready. :)
Rob Hausam (Apr 26 2020 at 01:05):
Any time, @Jean Duteau. I have another code system that I'm planning to add now, too, so it would probably be good to get both of them done at the same time. Just send me what you have.
Rob Hausam (Apr 27 2020 at 04:35):
@Jean Duteau Let me know if you have a list of the ICD-9-CM codes that you need.
