Medicare Advantage vs. Medicare Supplement: How to Compare
Both start with Original Medicare. From there, they work very differently — here's a side-by-side look.

The fundamentals
How each is built
Medicare Advantage bundles Part A and Part B through a private insurance carrier, usually with a provider network, often with extra benefits and Part D prescription coverage built in. You stay enrolled in Medicare; the plan becomes how your coverage is delivered.
A Medicare Supplement, also called Medigap, works alongside Original Medicare instead. Original Medicare pays first, and the supplement helps pay the costs Medicare leaves behind. If you want drug coverage with a supplement, you add a separate stand-alone Part D plan.
Side by side
Where they actually differ
On paper both start with Original Medicare, but the day-to-day experience of using each is different. These are the six differences that matter most in practice.
Extra benefits
Many Medicare Advantage plans bundle dental, vision, or hearing benefits; Medigap plans do not include these, though they can be added separately.
Monthly cost pattern
Medicare Advantage often has a lower or no additional monthly premium beyond Part B, with variable copays and coinsurance up to an annual out-of-pocket maximum. Medigap carries its own monthly premium, generally with more predictable costs when you use care.
Referrals and prior authorization
Some Medicare Advantage plans, particularly HMOs, require referrals or prior authorization for specialist care; Medigap does not.
Switching later
Medicare Advantage plans can generally be changed each year during the Annual Enrollment Period; applying for a Medigap plan outside your one-time Medigap Open Enrollment Period may involve medical underwriting.
Coverage while traveling
Medicare Advantage plans are typically limited to their network or service area except for emergencies; Medigap goes anywhere in the U.S. that accepts Medicare.
Making the call
Questions worth asking yourself
Do you travel often or split time between two places? If so, a plan built around a local network may frustrate you, while coverage that follows Original Medicare travels anywhere Medicare is accepted.
Do you have specialists or a hospital system you don't want to risk losing access to? Networks change year to year, so it is worth confirming the providers you rely on participate in any plan you consider — and deciding how much that certainty is worth to you.
Would you rather pay more predictably each month, or less monthly with more variable costs depending on the year? Neither pattern is wrong; they simply suit different budgets and temperaments.
There's no universally right answer — it depends on your own health, budget, and habits, which is exactly what a coverage review works through with you, at no cost and with no obligation.
