Medicare Advantage plans are local. Each one is approved for a service area of specific counties, and its network is built around the doctors and hospitals there. That works well until you visit grandchildren in another state, spend winters in Arizona or Florida, or take a long road trip.
This guide explains what every Medicare Advantage plan must cover away from home, where the plan types differ, and the residency rule that catches snowbirds. It also uses our count of CMS’s 2027 plan files to show how many plans give you some out-of-network coverage, and which companies sell PPOs in the most states.
