I’m so glad you are addressing this, Zipporah, because I fear that many people have not added Supplemental coverage to their Medicare at all, let alone the best coverage. Supplemental Medicare coverage is a game changer when the costs start piling up. Doing my Dad’s taxes this year, his total out-of-pocket for prescriptions and extra medical expenses was only $2,600 due to the good D and Supplemental coverage he and my Mom started paying for 15 years ago, and have never lapse since. In his case, living in Michigan, there is only one game in town, UnitedHealth, as far as I am able to discern, so he is fortunate that the coverage is good. Before my Mom died, her treatment for frontal lobal dementia was getting very extensive, but due to their coverage, it did not derail their retirement savings. As to the best coverage, it is a state-specific issue so at least that narrows people’s search.
