Where's the Beef?

Ron received word a few days ago that he now quailies for Medicare . No, he is not 65. He is receiving it because he has been disabled for over two years. What we need to do is read through the literature, visit the website and figure it all out. Does he need supplemental insurance? Where would he get that from? If I can drop him from my insurance, that could save us a substantial amount of money each month.
