If you have great insurance
, it could cost you nothing. If you paid cash for a bypass at a hospital, it can cost you upwards of $30, 000. The average cash price for a band is close to $20, 000 but there are chop shops that will do it for as little as $13, 000 (and even less in mexico). I would not bargain shop. I have seen a lot of complications from these bargain places.
