When I got my 3rd class medical certificate in 2017 as a student, it took a long time because of a single kidney stone in my medical history. I did not have have any retained stones and provided supporting documentation from my urologist. I eventually got it, but with the CACI program requirements for a retained stone. I was excited to be done with the process and have my medical, so put that aside. My current medical expires in Feb 2022, but I'd like to get ahead of the process. How do I appeal the requirement to be in the CACI program and has anyone had luck with this? I had one stone that passed on its own without complications. I provided scans that I was not retaining any stones. So it's a waste of time and money for me to be in a program for people that have retained stones. Can I get out of this?
