I have no clue how any of it works through medicare. I went with SilverScript for my medicines-there is little to no monthly premium. My co-pay is under $11 on 3 prescriptions. But with Part D they were going to cost me some wheres between $95 and $150. These amounts depended on either who I talked to or the day of the week I called. Neither of which I can afford. Also keep an eye on your 80/20 A friend of mine is being billed over $3250. on a $3700. hospital bill. Apparently there's a newer new math the gov. did not tell us about.
