I was fortunate, the cost of gastric bypass surgery for me was covered by my insurance company after fulfilling all the requirements as stated above. I had my surgery done at the Cleveland Clinic, a designated Center of Excellence by the American Society for Metabolic and Bariatric Surgery.


I had a wonderful, experienced surgeon and staff who took me through the entire process from beginning to end. My labs, evaluations, doctor visits and surgery were all done in one place and best of all the staff took care of handling all my insurance paperwork and the pre-certification process.  Having a qualified surgeon with an experienced staff can go a long way in obtaining insurance approval!
