Khaled,
I think I previously mentioned how I deal with endoscopies I do at the hospital. I am assuming you have endoscopy software in your endo suite. Our hospital uses Provation, and their IT folks put CutePDF on the Provation terminal. That way I can "print" the endoscopy report directly to a thumb drive, then import it to a patient chart back at the office. I use UpDox to send the patient a report summary and copy of the procedure note. (That way I don't have to wait around forever making sure the midazolam has worn off to discuss the findings in the typical routine or screening cases.) However, a staff member could do just the import if that is not your style. Then you can do either a chart note that just has a template entry saying "see endoscopy report this date" or an addendum using the same template, and generate a new superbill. That really takes only seconds of your time, and you have a digital copy of the procedure in full color if it is required.
