Okay. Let’s say you created a list Patient_Status with these elements:
And you wanted to add this to the form that to the demographics form, you would add another row like the one with Patient_Status to the Layout for Core/demographics below:
Now, if you must have it on the appointment form itself, then you will need to edit that form and create fields in the database for that. Unfortunately that will require some programming.
The database table for the appointments is openemr.openemr_postcalendar_events. I believe the php file that would need to be edited is this one: openemr/interface/main/calendar/add_edit_event.php
