By default, Medical Alert Processor either creates or updates a patient's medical alert information. Medical alerts already linked to the patient's record will be updated; medical alerts not yet linked will be added.
To remove a specific alert from a patient's record, the HL7 message must provide a value of CR for the MedAlert - Processing Code chart data field. The MedAlert - Processing Code chart data field must be mapped to an HL7 field in the same segment as the medical alert information.
