Where Indiana sits among the states
50.3% of everyone with Medicare in Indiana is in a Medicare Advantage or other health plan rather than Original Medicare. That puts Indiana 27th of 51, between Arizona above it and Idaho 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.
