FHIR seems to have implemented their own coding systems. For example, this was found in a Synthea patient:

          "valueCoding": {
            "code": "2106-3",
            "system": "urn:oid:2.16.840.1.113883.6.238",
            "display": "White"
          }

Which seems to be from: https://www.hl7.org/fhir/us/core/CodeSystem-cdcrec.html

I'm not seeing anything on the Athena terminology download page for this (login required).
https://athena.ohdsi.org/vocabulary/list

The code '2106-3' does appear in the standard download of terminology from Athena but as a LOINC code for a Choriogonadotropin test (so, not the same thing).

Are these FHIR terminologies available for OMOP in Athena (or elsewhere)?

Is there a place to download all of these FHIR terminologies in csv (or other bulk uploadable format)?

The FHIR terminologies can be downloaded as XML or JSON. Some have hierarchy and relationships, so flat CSV files are harder, though I believe there's a proposal to add that to FHIR IG publication tooling in the future. Note that FHIR is a data exchange standard and the terminologies themselves are defined in a variety of places - some on http://terminology.hl7.org, some in the core FHIR specification and some in different FHIR implementation guides (which can be defined by anyone). As such, there won't be a single place to download content, though there are registries you can use to search and download large sets of them.
