ADT^A15 — Pending Transfer
The transfer is about to happen: A15 announces the future destination (bed, service) without yet moving the patient. A02 will confirm execution.
Purpose
A15 announces a planned transfer (physician prescribed the move, place secured at the
receiving service, expected in the coming hours). PV1 still reflects the current
location, and PV2 (Patient Visit - Additional Info) carries the planned destination via
its Prior Pending Location or the appropriate fields.
A15 → A02 is the standard sequence: pre-reservation then actual transfer. If the transfer is cancelled in between, an appropriate cancellation is emitted (per local rules, A26 Cancel Pending Transfer practical variant).
Segment structure
Structure ADT_A15 with PV1 (current state) and PV2 (planned destination).

MSA|AA|MSG00015001 Common errors
- PV1-3 wrongly updated: A15 does NOT move — PV1-3 must remain the current location. Destination belongs in PV2.
- No A02 after A15: systems stay stuck on the pre-reservation indefinitely.
- A15 / A02 confusion: use A15 when a planned time > 1h in the future, A02 when the move just happened.
