Band over previous bypass

Hi everyone!  I had surgery 4 years ago and am now left with no restriction.  I originally lost about 121 pounds but have gained 20 of those pounds back.  I've fought those pounds for about 6 mons I realize it's not a lot but it's troubling me.  I'm curious I had the bypass with another insurance with no problems through anthem.  Now I have united healthcare and my company does not have a rider on their policy.  If I do this it would be self pay.

would this be considered lapband surgery ?  Does anyone know the cost for self pay with that.  Is it possible to get some things paid for by the insurance company such as anesthesia and self pay the rest.  Curious how this worked for some of you!  I probably can scrounge up $5,000-$7,000 out of pocket.
