So at LOINC we've been doing some pilot work to export all LOINC panels and forms (including the CMS-required assessment instruments) as Questionnaires based on the Argonaut profile. They're up on our development server (requires loinc.org login). Here's an example for IRF-PAI-1.10 https://fhir-dev.loinc.org/Questionnaire/83265-9

Authorization required?
Daniel Vreeman (Sep 14 2019 at 18:00):
yes, basic auth with a LOINC.org account will work. caution: this is a test server and won't always be publicly available. But it is for the connectathon.
Daniel Vreeman (Sep 14 2019 at 18:35):
A couple of thoughts on the PACIO approach/implementation. First, Questionnaire.item.code should have the LOINC codes in it. (CMS codes could be added as an alias).
Daniel Vreeman (Sep 14 2019 at 18:36):
Second, it'd be good to define the choices as ValueSets (and then reference them in each item). LOINC has ValueSets defined via the LL codes (which contain options enumerated as LA codes)
Daniel Vreeman (Sep 14 2019 at 18:47):
Third, could think about the LinkId pattern...whether to use "Section N/ CMS code" or the hierarchical position via LOINC codes. In our model we adopted the convention of the LOINC parent/child path, e.g. "85410-9|85483-6".

Also, for CMS's goals of taking a QuestionnaireResponse submission into QIES, should look at SDC's DataExtraction module that describes how to extract data from responses into other resources like Observation (which has support for searching, etc)
Daniel Vreeman (Sep 15 2019 at 09:59):
I was talking about this with @Lloyd McKenzie and think it'd also be useful to define an extension for QuestionnaireResponse to carry item.code over from the Questionnaire. That way receiving systems (e.g. an answer bank or system like QIES) could process the response instances into coded representations (like observations) without having to look back at the questionnaire definition each time.
