You can get a good idea of the different issues people have faced with their insurers by browsing some of the old threads on the site. It's impossible to tell you which companies always cover the surgery, because all companies make decisions based on individual medical situations.
Certainly there are carriers that are more band-friendly or less band-friendly, but so much depends on your own circumstances that generalizations are pointless. Which carriers are available to you?
