| ===MSH-10 Message Control Id===
| |
|
| |
| (original paragraph broken out into individual propositions)
| |
|
| |
| # Definition:
| |
|
| |
| 1. This field contains a number or other identifier that uniquely identifies the message.
| |
|
| |
| 2. Each message should be given a unique identifier by the sending system.
| |
|
| |
| 3. The receiving system shall echo this ID back to the sending system in the Message Acknowledgment segment (MSA).
| |
|
| |
| 4. The combination of this identifier and the name of the sending application (MSH-3) shall be unique across the Healthcare Enterprise.
| |
|
| |
| Implications:
| |
|
| |
| Sending system must not repeat sequence after restart.
| |
|
| |
| Any other information that should be encoded?
