RPT is a repeat pattern datatype used by newer timing fields. It can express repeat pattern, calendar alignment, phase, period, and institution-specific timing codes.

In this guide, RPT appears in TQ1.3. That used-by list is a good reality check: the datatype is only half the story, and the field that uses it tells you the workflow.

The component panel above is expanded by default because most datatype pages are used as quick lookup pages. Start there for the exact HL7 v2.5.1 shape, then use the notes below for the practical gotchas.

RPT-1 to RPT-11: Component Quick Read

The generated component panel above is the formal quick lookup. The short version is below so you can scan the shape without counting carets by eye.

The table-backed components here are RPT-1, RPT-2, RPT-7, RPT-8. Keep those values to the table or value set your implementation guide names, especially when the field is crossing organization boundaries.

  • RPT-1 Repeat Pattern Code - Repeat Pattern Code. Type CWE. Table 0335.
  • RPT-2 Calendar Alignment - Calendar Alignment. Type ID. Table 0527.
  • RPT-3 Phase Range Begin Value - Phase Range Begin Value. Type NM.
  • RPT-4 Phase Range End Value - Phase Range End Value. Type NM.
  • RPT-5 Period Quantity - Period Quantity. Type NM.
  • RPT-6 Period Units - Period Units. Type IS.
  • RPT-7 Institution Specified Time - Institution Specified Time. Type ID. Table 0136.
  • RPT-8 Event - Event. Type ID. Table 0528.
  • RPT-9 Event Offset Quantity - Event Offset Quantity. Type NM.
  • RPT-10 Event Offset Units - Event Offset Units. Type IS.
  • RPT-11 General Timing Specification - General Timing Specification. Type GTS.

Practical Notes

Keep numeric values numeric. Do not mix display formatting, unit text, or currency labels into the number component when the datatype has a separate place for that meaning. A format validator for whole numbers or decimals is a simple way to catch this before the receiving system has to complain.

In HL7 Soup Web, click a field that uses RPT and the interpretation view will show which component you are sitting in and where that value lives in the raw message. That is especially handy with compact datatypes because one missing caret can move every value after it.

Official and Reference Notes

For formal reference, compare the generated HL7 v2.5.1 panel above with the HL7 v2.5.1 datatype list and the HL7 Terminology data type code system. Local implementation guides can narrow allowed values, tables, and component usage.
