Turning on the "Mask PHI" functionality masks private patient health information displayed within the HL7 Editor. This can be useful for showing someone else a message within HL7Spy while keeping confidential the information contained in the message. To active this functionality click the "Mask PHI" button in the Home Ribbon tab, in the "Options" group. Configuration for this feature is found under the "Editor Options" menu.
