Plastic Surgery
The insurance companies all look at these as "cosmetic", so you have to do twice as much to prove them wrong. My advice is to do these things: Tell ALL your doctors when you see them that you have rashes, sores, and odors coming from the skin flap. Tell them it is hard to keep the area clean and dry. Make sure it gets noted (even if you aren't experiencing it at the moment). Take pictures of any sores or redness to send to insurance. They key is document, document, document. My doctor wouldn't do the skin removal until I was stabilized in my weightloss for about a year. I'm glad now that he did because I lost a little more after surgery and now came back to where I should be. Good luck, and keep plugging away and insurance!
