So i contacted my insurance company and was told as long as the doctor is IN NETWORK and I meet the criteria the lapband surgery is covered 100% My only concern is that I have read some reviews from people who used one of the doctors I am thinking about using and there were some complaints that even though they surgery was covered, they received bills AFTER the surgery for people who "assisted", etc. she was upset because she said she asked in advance if there was anyone else she would receive bills from that she was responsible for and the DOCTOR had told her that he didnt use uninsured assistants so now she is stuck with a 4,000 bill..... so my question is: has anyone else experienced this? did you get bills after surgery that was not covered? Thank you for all your input!!!!
