Going on 3rd year of Medicare with a Plan G supplement. Its around $100 a month and after an annual deductible of $149 it covers everything (that medicare covers). I never pay a cent over the initial deductible. EnvisionRX is my Part D - its around $15 a month. I think all Part D's are pretty much the same. If you know you are going to have a lot of medical you need either F or G, F covers everything but premium difference is much more than the $149 deductible with G. Of course premiums vary based on gender and the state you live in. Good luck.
