orientation

After 2-1/2 years and 3 denials and more dr visits than I can say, insurance finally approved for me to see a surgeon. although 2 of my sisters have had successful surgery and third sister having surgery next week, I still dont know what to expect, because insurance is different. I am going in next week for orientation to see Dr Krahn and Dr Chin in San bernardino. I have United health care HMO, so I would like to know is how long after this initial appt, can I expect to have surgery. also I am about 10 lbs under what I need to qualify and I have worn weights to my primary, dr to get approved. I think I will still need them. Will they check to see if I am wearing weights?
