Lanterman Medical Bill Relief

I am Keith Lanterman from Sacramento, CA. My mother Ruth Lanterman had Chronic Osteomyelitis on her left foot. It was recommended that her leg be amputated below the knee. On January 15, 2019 she underwent surgery and spent two days in the hospital. She has been home now for four months and everything is fine. We are looking for assistance with the 20% copay of the cost for durable medical equipment that Medicare and Kaiser will not cover. My mother's goal is to be as independent as possible.
