HL7 LA1 Location with Address Variation 1

These are the generated components for the version selected at the top of the page. The article stays practical, and this panel follows the chosen HL7 version.

| 9 | LA1.9 | Address | AD | Address; Type AD. |
LA1 is a location with address variation. It combines a point of care, room, bed, facility, location status, and address pieces. It is older and less common than PL or XAD, but you may still meet it in pharmacy and location-related fields.
In this guide, LA1 appears in RXE.8, RXO.8. 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.
LA1-1 to LA1-9: 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 LA1-1, LA1-2, LA1-3, LA1-5, LA1-6, LA1-7, LA1-8. Keep those values to the table or value set your implementation guide names, especially when the field is crossing organization boundaries.
- LA1-1 Point of Care - Point of Care. Type IS. Table 0302.
- LA1-2 Room - Room. Type IS. Table 0303.
- LA1-3 Bed - Bed. Type IS. Table 0304.
- LA1-4 Facility - Facility. Type HD.
- LA1-5 Location Status - Location Status. Type IS. Table 0306.
- LA1-6 Patient Location Type - Patient Location Type. Type IS. Table 0305.
- LA1-7 Building - Building. Type IS. Table 0307.
- LA1-8 Floor - Floor. Type IS. Table 0308.
- LA1-9 Address - Address. Type AD.
Practical Notes
The safest habit is to populate only the components the receiving profile actually uses, and to keep each meaning in its own component. Empty components are better than a compact display string that a receiver has to reverse-engineer.
In HL7 Soup Web, click a field that uses LA1 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.
