Hi @dixonwhitmire glad to have you with us.
Unfortunately I do not know the answer to your question off the top of my head. OpenEMR has limited support for fhir in the current release but it’s something actively being worked on.
There’s currently a google summer of code project aimed at improving fhir support/compatibility.
You might have better luck on this discussion thread:
Also feel free to join the conversation on slack if you haven’t already:
