Medigap Policy?

I was wondering if anyone knows anything about Medigap policys? I believe I am elgilable right now for them since my medicare coverage just started in March. I think I have 6 months to sign up. Anyway- I am wondering if maybe I should do this, Im thinking that maybe they will pick up the other 20% of the surgery? Anyone know?

I would suggest calling Medicare and asking them, I know it's a hassle to get through to someone and I usually end up screaming "AGENT!!" at that stupid voice prompt like 5 times by the time I've got a human on the phone to speak with but if your lucky you might find someone who isn't an idiot over there to explain what a Medigap policy will pay for and if it would help. Good Luck, Lia
