What is identifier.system, and why is my PID-3 mapping warning about it?
Vaidya3 Kosha entries पर आधारित · synthetic AI उत्तर
An identifierin FHIR is more than a number — it's a number plus the namespace that issued it. That namespace is identifier.system, written as a URI.2
Your HL7 message carries both in PID-3: the ID MRN-1042 and its assigning authority SIDHI (component 4). You mapped the value, but not the authority — so the mapper warns that identifier.system is empty.1
"identifier": [{
"system": "https://healthatoms.com/mrn", // ← the authority, as a URI
"value": "MRN-1042"
}]
Bind the authority to a registered URI and the warning clears — now the same MRN can't be confused with one from another hospital.3
