In a few months I will transition to Medicare from private group insurance. Is there a place to get straight info that's not an insurance advertisement about what options I should or can choose? I've seen part D and other letters mentioned but it seems like a lot of double talk. Also is supplemental insurance something needed in addition to the options I may or may not choose? I know some is peoples experience/opinions and that's fine. I'm just trying to determine my best options before the big day arrives.
