NHS North West Genomics - Local Development build (v2.2.0) built by the FHIR (HL7® FHIR® Standard) Build Tools. See the Directory of published versions

| Draft as of 2026-09-20 | Computable Name: OrderIdentifier | ||||
No NHS Data Dictionary entry - a laboratory order identifier is a local Placer/Filler concept defined by HL7 v2/FHIR, not a nationally-defined data item.
Ubiquitous terms: Order Number, Requisition Number, Placer Order Number (the referring system's own number) / Filler Order Number (the receiving laboratory's own number).
| Ubiquitous Term | HL7 FHIR | HL7 v2 | OID | Notes |
|---|---|---|---|---|
| Order Number (Placer) | ServiceRequest.identifier (type = PLAC) | Placer Order Number (ORC-2) | none - locally assigned | Assigned by the ordering (Order Placer) system |
| Order Number (Filler) | ServiceRequest.identifier (type = FILL) | Filler Order Number (ORC-3) | none - locally assigned | Assigned by the receiving (Order Filler) system |
