HL7 ADT^A13 (Cancel Discharge)
ADT^A13 is the HL7v2 cancel discharge message, defined in HL7v2 from v2.1 through v2.8.2. Its v2.8.2 structure carries 31 segments and groups, 6 of them required.
Full message structure (v2.8.2)
Every segment and group the standard defines for ADT^A13, in order, straight from the machine-readable specification. Indented rows sit inside the repeating group above them. R is required, O optional, C conditional; ∞ means the group or segment may repeat without a defined limit.

Which HL7v2 versions changed ADT^A13?
ADT^A13 has been defined since v2.1. Consecutive versions sharing an identical structure are grouped, so a single row spanning several versions means nothing changed across them.
| Versions | What changed |
|---|---|
| v2.1 | First defined, with 5 segments and groups. |
| v2.2 | Added ACC, AL1, GT1, IN1, IN2, IN3, NK1, OBX, PR1, PV2, UB1, UB2. |
| v2.3 | Added DB1, DRG, PD1, ROL. |
| v2.3.1 | Same segments, but usage or repeat counts changed. |
| v2.4 - v2.5.1 | Added PDA. |
| v2.6 | Added ARV, SFT, UAC. |
| v2.7 - v2.8.2 | Same segments, but usage or repeat counts changed. |
