Epic R4 Patient.Read identifier masking


We are using Epic’s Patient.Read API to fetch patient records. Some (not all) of the patient identifiers are masked (ie, xxx-xx-6789 when the real value is 123-45-6789). We have an unrelated HL7 v2 ADT feed from the same customer and the identifiers are NOT masked there so it’s clearly stored in the database and it’s the FHIR API obfuscating the value. Is there a sensitivity setting or permission within Epic perhaps that controls how much of the patient identifiers are exposed on the FHIR API?

This is a question that is unlikely to be answered here - you’ll have to ask Epic directly through the epic developer program
