I had lap band surgery on April 28, 2011. I went for my first fill on June 6th. Having felt no restriction what so ever I returned for a second fill on June 13th. At that time they were unable to locate my port. The following Friday the surgeon met me and tried to fill me under fluor. He was unable to locate the port and decided I need to have revision surgery. The problem is that I am a self pay. The surgeon assures me that he will have no cost but the hospital does not want to cover this. My question is shouldn't all of the cost be covered since the darn thing never has worked?
