I got my letter yesterday. I use MEDCO for my part D. I notice they calculate how much is spent on medications by using the entire amount of money spent--by them and me. They aren't just counting the $4 or so it costs me to get the generic form of lipitor. They add in the amount they "saved" me. Yesterday I paid $197 out of my pocket for a three month's supply of NovaLog Mix 70/30.
