Copay for Prosthetic Leg

Flint lost his leg due to infection and because he is 6'7" tall he has had extreme difficulty in getting a prosthetic that fits correctly and doesn't cause him back and hip pain. Right now Flint is developing what is called a rhino horn on his stump which is due to a bad fit. A true fitted leg is ready and available to him but his insurance covers all but about 20% of the cost leaving him with about 3800.00 in out of pocket expenses.
