Medicare Below are some commonly asked questions relating to Medicare. If you would like my help with a Medicare issue, please contact my constituent service office in Kalamazoo (269-385-0039) or St. Joseph/Benton Harbor (269-982-1986). How do I apply for Medicare? I lost my Medicare card. How do I get a new one? I recently moved to another state. How do I update my address with Medicare? Although I am able to walk, I have a difficult time walking long distances. Would Medicare allow payment for a wheelchair or Power Operated Vehicle (POV)?
