Where Ohio sits among the states
56.7% of everyone with Medicare in Ohio is in a Medicare Advantage or other health plan rather than Original Medicare. That puts Ohio 9th of 51, between North Carolina above it and Florida 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.
