Michael Murphy provides good advice. I encourage you to follow it. Additionally, work with your transplant social worker and/or insurance counselor to consider other possible resources. Your transplant center isn't going to permit a kidney to essentially go to waste due to funding issues post-transplant. The American Kidney Fund (
http://www.kidneyfund.org/financial-assistance/) might provide funding and may also have suggestions too.
Seek out advocates and work with them. Good luck.
