Every Aetna policy is different. You should call the number on back of your id card to ask your specific questions. I have Aetna through AT&T and there are no limits in the policy for bariatric surgeries. I am in the beginning stages of band to sleeve revision. However, even though an insurance company may say they cover the process, there have been times when, after surgery, the insurance company refuses to pay. That is why the doctor must put you through all the paces to dot the i and cross the t, to assure that insurance will pay and you will not be left holding a bag of debt. Be patient. It will happen in due time. My new sleeve surgeon is making me gain 20 pounds to assure insurance payment. Imagine that!!!! So with all the tests, dietitian, psychologist, etc, appointments, it will be about two months before a surgery date can be set. The good news is that he removed all the fluid from the band. I have thrown up at least once a day and sometimes more for the past four years. I will be so very very happy to get this band removed! Good luck to you as well.
