| | |
| :--- | :--- |
| *Official URL*:http://fhir.geniesolutions.io/StructureDefinition/eorders-diagnosticrequest-display-sequence | *Version*:1.2.60 |
| Draft as of 2026-04-05 | *Computable Name*:EOrdersDiagnosticRequestDisplaySequence |

A display sequence number for an individual test/service that matches the sequence as seen on a paper order form. This more easily allows for reconciliation of paper and digital requesting data by the filler. Sequence numbers do to need to be contiguous and sequence is low to high.
