@mayo2go, Hi, Ken, I hear you saying that the claim should be handled by the transplant team, and that you have no contact information for the transplant team. Since you were tested at Mayo Clinic Kidney Transplant Department, in Arizona, I want to share the contact information with you. You can call or email.
