I don't understand Bernie's Medicare for all

41. As I understand it, a Medi-Gap or supplemental policies sold after January 1, 2006, do not include

prescription drug coverage. If you want prescription drug coverage today, you need to sign up for Medicare Part D.

Unless there is something I am not aware of, if you are saying that your supplemental covers generics, and 50% non-generics, I suspect you have a supplemental that was obtained before 2006. It doesn't sound like you have an Advantage Plan, which could also cover drugs, and perhaps other services not covered by standard Medicare.

For those that need Part D, the premiums for Part D depend on one's AGI

Medicare Advantage Plans usually bundles things together and sometimes include things that Medicare does not cover, such as drugs, vision, and dental., but Medicare Advantage plans can limit where you can go, or what services are covered, and have more restrictions than standard Medicare Supplemental Plan such as A, B, C........F etc. The most comprehensive supplemental plan would be F.

The 107 dollars that you pay is for Part B as you said, but you also indicated you have a supplemental, which should have a premium cost you have to pay also. As I mentioned above, a supplemental can cost an additional 100 dollar premium, and above depending on what type of supplemental you have.

Everyone's situation is different.
