Where Wisconsin sits among the states
57.7% of everyone with Medicare in Wisconsin is in a Medicare Advantage or other health plan rather than Original Medicare. That puts Wisconsin 6th of 51, between Maine above it and Connecticut below. 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.
