Topic: Warning message when using Radlex codes

Shruthi Rajasekar (Oct 22 2021 at 00:51):

Hi all,

I have implemented a ValueSet with Radlex codes. In the qa file, there seem to be several warnings that says the following :
" ValueSet.compose[0].include[0].concept[0] warning The code 1303 is not valid in the system http://radlex.org/ "
The codesystem was used as mentioned in FHIR documentation for Radlex : http://radlex.org/ . But should it be something different?

Thanks for the help :)

@Shruthi Rajasekar We also had an inquiry about providing additional support for RadLex a couple of days ago.

I think that @Grahame Grieve may have some plans for this?

I don't have particular plans - just hoping someone makes up a code system resource for it

working with the team here on a Python script that takes the RadLex.xlsx as input to create a rudimentary CodeSystem resource - will share with you out-of-band when done. Could then work with RSNA to publish it natively as FHIR on their site.

@David Simons , from another post asking about RadLex:

RSNA and LOINC have changed the documentation for Radlex codes since we orginally wrote the binding. I'd point you at the "LOINC/RSNA Radiology Playbook and Playbook Core" section of https://loinc.org/fhir/ to get the latest value set.

This doesn't cover the non-playbook portions though.

Also, there is a branch of THO that includes RadLex (http://build.fhir.org/ig/HL7/UTG/branches/UP-252-add-radlex-to-tho-per-hta/CodeSystem-RadLex.html). I assume that means it will be in an upcoming release of THO.

Grahame Grieve (Feb 23 2022 at 20:48):

that code system doesn't have any content, so the code system @David Simons is creating will still be useful. David, you could consider contributing that to fhir.tx.support here: https://github.com/FHIR/packages/tree/master/packages/fhir.tx.support.r4
