We have code that that attempts to download an XML CCDA from Cerner using FHIR. This code previously worked against the sandbox for several of the test patients on there, but now I'm unable to find any patient with an XML CCDA document reference available. We are also having issues with this same use case with one of our customers, which I previously messaged about with no response.
The specific query I'm executing is:
https://fhir-ehr-code.cerner.com/r4/<redacted uuid>/DocumentReference?patient=Patient%2F12724066
For most patients, it returns 10 results no matter what _count is provided. I've also tried specifying a few type attributes:
- http://loinc.org|81214-9 - from the LOINC website as the LOINC type for a CCDA R2 & R2.1.
- http://loinc.org|34133-9 - gleaned from the DocumentReference documentation
These universally result in no documents being returned. Can someone please clarify exactly how I might go about downloading a CDA from Cerner? The examples in the documentation do not appear to work correctly any more.
Thanks!
