Hassan Mirza · Jan 27

Currently in the health connect code, we are using Epic FHIR API Patient.Create, code return 200 or 201 status values, we process the message based on this return values.

Now I need to use Epic FHIR Patient.$match API, need to check FHIR Error code 4101 for this API. I looked for FHIR statndard return code, but this this seems not standard code, please advice how can I check 4101 value?

@Hassan Mirza , 4101 is a response code used by Epic to mean "no results found", the Patient.$match API spec and codes can be found here: https://fhir.epic.com/Specifications?api=10423

4101

Warning

Resource request returns no results

A request for data that was otherwise valid but no information was documented or found (i.e. a patient with no pertinent implanted devices, or a demographic search where no patients met the search criteria).

If you think this is being returned incorrectly, definitely reach out to Epic directly for support!
