Maybe a picture of a Dr. in his lab coat for Part B?
I have seen one where it lists A, B, C and D on the left but leaves C blank and then on the right lists A, B, C and D and explains what Part C is and leaves A, B and D blank. That way they basically know there are 2 distinct ways to get their coverage. And beside Part B it listed $104.90 so they are aware of this premium in addition to whatever plan they choose.
