Lenny get a new liver

Hello, my name is Hunter and I am trying to raise money for my friend who desperately needs a new liver. Medicare is only covering 80% of the 500k surgery and he needs the other 20% to be able to make it. He was told he would possibly be able to get enough funds by march 1 but he was also told he won’t make it that long..he has had medical issues his whole life but a new liver will help more than anything.
