Medicare coverage while travelling

Contrary to an earlier post, our zero additional cost UHC Advantage Plan w/Part D is exactly that, zero additional cost over the standard Medicare premium we all pay. Yes, the Passport feature does have limitations, but we've found the rare times we've needed "outside" service that the out of plan co-pays still weren't as costly as the various Supplement annual premiums are. The majority of the time we've either been in or near enough to an included state/county, or in our "home" region, that our normal plan co-pays applied. Emergency and Urgent care are covered everywhere in the US with our plan.
