I reside in PA and have what most would consider great healthcare provided by my parent's work. My benefits will run out in a few years, when I graduate college. I have large breasts, (34-d) and am planning to at some point in my life get a breast reduction because they are uncomfortable, especially with my small body/stature. Will my Blue Cross/Blue Shield PPO plan cover the cost of the breast reduction surgery?

Insurance will only pay for plastic surgery if your breasts are causing you health problems. If you can convice a doctor of that, he will be better able to convince an insurance company that it was deemed medically necessary.

get a free consultation with a Plastic Surgeon
the Md's biller will know or be able to find out for you after the diagnosis/ exam

Maybe, maybe not. Definitely not before you turn 18, and then only if it is deemed medically necessary.

i'm not really sure about this but i watch those plastic surgery shows alot and most insurence companies do AND my aunt had this done about 3 years ago (we live in Pittsburgh).. it would be a whole other story if you wanted to make your boobs bigger though because thats a cosmetic surgery. just tell them that your breasts are the source of your back pain or whatever is bothering you and that instead of years of going to a chiropracter, getting them reduced would instantly fix the problem. most likely it'll be covered because its not just cosmetic its for you health also
