A Mother's Wish: Fund Her Son's Prosthetic

My name is Dolores, and I am trying to collect money for my son's prosthetic leg. Just a background history Louis was a diabetic for 30 years went into renal failure at age 38 and in 2020 got 2 kidneys and a pancreas. This bacterial infection was the aftermath of the effects of the diabetes. I'm not sure how much the insurance will cover, if it covers it at all, so I would like to start now so he doesn't have to worry about that. Thank you all.
