Im writing on behalf of my father who is currently a patient at Mayo clinic Arizona. He is dealing with Liver failure and has since become Diabetic. His medications are extremely expensive and insurance isnt covering much. He is on disability. Are there any programs or anything I can do to lesson his cost of medications? What options are available to him? The insulin is a real killer in cost.He is almost to the point where he will have to not take certain prescriptions do to the cost.
