Hello everyone,Im trying to find a medicare supplement to pay 20% for my wls.I just got approve for social security,and the lady said I will have to get a supplement to pay 20% ,cause medicare pays for 80 %.I called a couple of places for quotes but these quotes are out rages.Some is 269 to 289 on up just for a supplement.I wanted to know if anyone had to do the same thing,find a supplement and do yall know who will pay for the wls 20%?

Hi,Do u have  medicaid? If you have medicaid  along with  your  medicare than  the docter will take your  medicare and use your medicaid as a supplement.
