Why is it important for Epic to check MSH-11 and MSH-12 values in incoming messages?

The significance of checking MSH-11 and MSH-12 values in incoming messages is rooted in ensuring that messages conform to expected processing IDs and versions. MSH-11 pertains to the Message Type, while MSH-12 includes the version ID of the message. This validation process is crucial because it helps the receiving system identify the nature and format of the incoming message, ensuring compatibility with system processes.

When Epic verifies these fields, it can determine whether the message is intended for the current system, adhering to the expected version and structure for seamless processing. If MSH-11 or MSH-12 contains unexpected values, the system can flag the message for further review or rejection, preventing potential errors or data corruption that could arise from processing incompatible message formats. This quality control step is vital in maintaining the integrity and reliability of information exchanged between systems.
