Where New Mexico sits among the states
49.7% of everyone with Medicare in New Mexico is in a Medicare Advantage or other health plan rather than Original Medicare. That puts New Mexico 29th of 51, between Idaho above it and Washington 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.
