@Dymshyts here is a link to the modifier page we put in the F2O IG spoken of in today’s vocab meeting
https://build.fhir.org/ig/HL7/fhir-omop-ig/en/FHIRModifierExtensions.html
Would appreciate your feedback about this or any other page in the updated v2.0 (STU level) IG. If you need any orientation to feedback mechanisms - please reach out. Happy to help!
cheers
