Questions, possibly stupid: I am researching part D, having decided to apply for Parts A and B, and a state retiree supplement. (Supplement from another state than current residence, and supplement does not cover "over Medicare payment charges." Those are illegal in this state, so I think I am good there.) It does not include prescriptions, so I need part D. Currently taking two drugs, a tier 2 and 3. Not so worried about them, but some of the part D plans say chemo is not covered. Yet that seems to be part of the 6 protected classes of drugs. I don't need it now, but having had many cancers due to a genetic mutation, cannot assume I have seen the end of that. So what is true--can they or not, exclude chemo drugs? I was already perplexed enough with trying to figure out where I hid my crystal ball to let me know that drugs I will need in the future, but this is worse! Thanks.
