Where Michigan sits among the states
62.8% of everyone with Medicare in Michigan is in a Medicare Advantage or other health plan rather than Original Medicare. No state has a larger share: Michigan is where Medicare Advantage has taken the most ground, with Alabama next. Across the country the same figure runs from 62.8% in Michigan down to 3.0% in Alaska, so what counts as the ordinary choice depends on where a person lives, and this is what it is where they do.
