NHS Data Dictionary and Model

No NHS Data Dictionary entry - a v2/FHIR technical grouping identifier, not a nationally-defined data item.

Ubiquitous terms: Order Group Number, Placer Group Number, Panel/Batch Number (the number linking several individual orders placed together, e.g. a test panel or a single specimen requesting several tests).

Mapping

Ubiquitous Term HL7 FHIR HL7 v2 OID Notes
Order Group Number ServiceRequest.requisition (type = PGN) Placer Group Number (ORC-4) none - locally assigned Groups several ServiceRequests placed together
Parent Order Number ServiceRequest.requisition (type = PGN) Parent (ORC-8) - provisional none - locally assigned The parent order's Filler (or Placer) Order Number, on a Sub-Contracted, Reflex or Work Order
