These are the generated fields for the version selected at the top of the page. The document stays the same, but the reference panel follows that version.

RXR describes the route, site, device, and method for administering a pharmacy or treatment item.

The standard describes RXR this way: The Pharmacy/Treatment Route segment contains the alternative combination of route, site, administration device, and administration method that are prescribed as they apply to a particular order. The pharmacy, treatment staff and/or nursing staff has a choice between the routes based on either their professional judgment or administration instructions provided by the physician.

Pharmacy/treatment segments split a medication workflow into ordered, encoded, dispensed, administered, component, route, timing, and instruction details.

Be very clear about whether a field describes what was ordered, what the pharmacy dispensed, what was scheduled to be given, or what was actually administered. Those are related, but they are not the same event.

The v2.5.1 structures show RXR in CSU_C09 - CSU - Automated time intervals for reporting like monthly, OMP_O09 - OMP - Pharmacy/treatment order, ORP_O10 - ORP - Pharmacy/treatment order acknowledgment, and PEX_P07 - PEX - Unsolicited initial individual product experience report, and 19 other message structures. That tells you where it can appear, but the implementation guide still decides which optional fields are meaningful.

For practical interface work, read the generated field panel for datatype, required, repeatable, and table details, then use the notes below to decide what the field should mean in the receiving workflow.

RXR-1 Route RequiredR SingleS TypeCE Table0162

RXR-1 qualifies the pharmacy workflow rather than identifying it. This is the sort of field receivers often use for branching, filtering, or display grouping.

Use the agreed value set, starting from HL7 table 0162. A local code without an agreed coding system is a small ambiguity that becomes a mapping problem later.

RXR-2 Administration Site OptionalO SingleS TypeCWE Table0163

RXR-2 qualifies the pharmacy workflow rather than identifying it. This is the sort of field receivers often use for branching, filtering, or display grouping.

Use the agreed value set, starting from HL7 table 0163. A local code without an agreed coding system is a small ambiguity that becomes a mapping problem later.

RXR-3 Administration Device OptionalO SingleS TypeCE Table0164

RXR-3 helps identify the product, software, device, or equipment involved. It is particularly useful when support needs to trace behaviour back to a specific build, lot, instrument, or manufacturer.

The generated panel links this to HL7 table 0164; many real interfaces narrow that list further, so follow the receiver's implementation guide.

RXR-4 Administration Method OptionalO SingleS TypeCWE Table0165

RXR-4 qualifies the pharmacy workflow rather than identifying it. This is the sort of field receivers often use for branching, filtering, or display grouping.

Use the agreed value set, starting from HL7 table 0165. A local code without an agreed coding system is a small ambiguity that becomes a mapping problem later.

RXR-5 Routing Instruction OptionalO SingleS TypeCE

RXR-5 carries Routing Instruction for this pharmacy workflow. Populate it only when the receiver has a clear use for it, and keep the value in the datatype shape shown in the generated field panel.

RXR-6 Administration Site Modifier OptionalO SingleS TypeCWE Table0495

RXR-6 qualifies the pharmacy workflow rather than identifying it. This is the sort of field receivers often use for branching, filtering, or display grouping.

Use the agreed value set, starting from HL7 table 0495. A local code without an agreed coding system is a small ambiguity that becomes a mapping problem later.
