So as of right now I have no health insurance. I work part time at my job so I don't get benefits. However, I'm 22 so I can get added to my parents insurance which is Health Plus in Michigan. I weigh about 360 and am only 5' 2". I really want to get lap band surgery but does anyone know or had any experience with Health Plus? Do they cover the cost or part of it? Any help would be really appreciated.
