Original Medicare vs. Medicare Advantage: How to Choose
Learning goal: Compare Original Medicare and Medicare Advantage on doctor choice, costs, extra benefits and travel, and know what to check before choosing.
Short answer
Original Medicare lets you see any doctor or hospital that takes Medicare, but has no yearly out-of-pocket limit unless you add Medigap; you add Part D for drugs. Medicare Advantage is a private plan bundling A, B and usually D, often with a network, prior authorization, a yearly out-of-pocket limit and extras like dental.

The Fuller Picture
The trade-off is choice and predictability versus cost and extras. Original Medicare plus Medigap gives broad choice and predictable costs, at higher premiums. Medicare Advantage plans often have low premiums and extra benefits, but you may need to use the plan's network and get approval for some care. Original Medicare generally doesn't cover care outside the U.S.

Frank and June
Frank travels between Florida and Ohio and wants any doctor, so he picks Original Medicare with a Medigap plan and a Part D plan.
