My dad has diabetes and had his pinky toe amputated

The hospital and his primary care physician wont take him in to stitch his open wound due to his insurance. Northside hospital is where he was at during the time when he had his toe amputated. The insurance we have is humana and just recently there is a law that makes it where people cant be discriminated by the kund of insurance. Now my dad is at home with an open wound, a split in the middle where his pinky toe used to be, and its just wrapped up in bandages. Blood drips from his sock everyday because of this situation. Something is definitely wrong in this picture and i have a hint that its either discrimination or negligence. Of course i am here to ask a professional because this is pretty serious
