Plastics Insurance experience?

Hello!  I am curious if anyone has any experience getting approved for body contouring through insurance. I paid cash for my surgery back in 2007 and the amount of excess skin I have is ridiculous and uncomfortable to say the least.  Granted..I do not have boils bursting out of every fold ..I do have issues that i am now realizing that maybe I should start documenting.  If anyone is willing to share can you tell me what your insurance providers requirements were, what type of insurance, your pre op BMI and anything else you think that might be helpful. My case is going to be weird because I paid cash originally in the first place. Any advice would be greatly appreciated. 

Thanks!
