I was feeling very frustrated too with the clearances. I'm scheduled to have surgery Dec 4, 2019 and I had to do so much running around and pestering my Internal Medicine Dr. for my clearance, that I was really frustrated and was about to give up. I first visited my surgeon in Sept, and he gave me all the paperwork to start the process. I did all the was requested of me and after running around like crazy, I got my clearances. Most of the the problem was with the personnel in my Internal Medicine Doctor's office. My concern now is that Medicare does not give approval prior to Surgery. The surgery has to be performed and then submit for approval. I have Medicare and United Healthcare as my secondary insurance, so hopefully it will be approved. I do meet all the criterias, but I am not 100 pounds overweight, I have to lose about 93 lbs, hopefully that won't be a problem with the insurance. My BMI is 40. Has anyone had problems with Medicare approving the Surgery?
