In enhanced mode, which acknowledgment code is returned if the originating message is accepted successfully?

The acknowledgment code that indicates a message has been accepted successfully in enhanced mode is "CA," which stands for "commit accept." This code is a confirmation from the receiving application that not only has it received the message, but it has also processed it appropriately and has committed to the action associated with that message.

In the context of HL7 messaging, the acknowledgment codes play a crucial role in ensuring that messages are successfully transmitted and processed between systems. The "CA" code is specifically used to denote successful processing, providing assurance to the sender that their message was received as intended.

Other codes serve different purposes and indicate various states of message processing. The "CR" (commit reject) code signifies that the message was rejected, whereas "CE" (commit error) indicates an error occurred during the processing of the message. The "AA" (application accept) signifies that the application has received the message but does not specifically confirm a successful commit to the action associated with the message, making "CA" the most appropriate acknowledgment code for successful processing in enhanced mode.
