Medicare Advantage

vs Medigap

What's the Difference?

Medicare Advantage vs. Medigap…What’s the Difference?

Have you ever found yourself scratching your head over Medicare options, wondering, “Do I choose Medicare Advantage vs Medigap? What’s really the difference?”


If so, you’re not alone. Many people including those turning 65 find Medicare confusing, especially when it comes to deciding how to cover costs beyond Original Medicare. Let’s break it down in a simple, friendly way so you can make an informed choice.

Original Medicare

Before diving into Medicare Advantage and Medigap, it helps to understand Original Medicare. Medicare Part A covers hospital care, while Part B covers doctor visits and outpatient services. But here’s the catch: Original Medicare doesn’t cover everything. You’ll still have deductibles, copays, and coinsurance, which is where Medigap and Medicare Advantage come in.

Medicare Advantage: An "All-in-One" Plan

Medicare Advantage, sometimes called Part C, is offered by private insurance companies approved by Medicare. Think of it as a bundle: it combines Part A and Part B coverage, and most plans include extra benefits like prescription drug coverage, dental, vision, and sometimes even gym memberships.


The biggest appeal? Predictable monthly costs. You usually pay your Part B premium plus a single plan premium. Many people like the convenience of having most of their coverage through one plan.


However, there are some trade-offs. Medicare Advantage plans often have network restrictions, meaning you may need to see doctors within the plan’s network. Also, you might face higher costs if you require care outside the network. And while many Advantage plans offer low or even $0 monthly premiums, they can have higher out-of-pocket limits when you need more care._

Medigap: Supplemental Coverage for Original Medicare_

Medigap, also called Medicare Supplement insurance, works differently. It doesn’t replace Original Medicare; it “fills the gaps.” That means it helps cover deductibles, coinsurance, and copayments that Original Medicare doesn’t fully pay.


One of the biggest advantages of Medigap is flexibility. You can see any doctor who accepts Medicare, anywhere in the U.S. This makes it ideal for people who travel frequently or prefer a wider choice of providers.


Medigap plans usually come with higher monthly premiums compared to some Medicare Advantage plans. But the trade-off is predictable out-of-pocket costs. If you value stability and fewer surprises in medical expenses, Medigap is often a solid choice.

Which One is Right for You?

If you want an all-in-one plan with extra perks and are comfortable with network restrictions, Medicare Advantage might fit your lifestyle. If you prefer predictable costs, broader choice of doctors, and travel flexibility, Medigap could be the better option.


As an insurance agent, I always encourage clients to consider their health needs, budget, and lifestyle when making this choice. There’s no one-size-fits-all answer, but understanding the differences helps you make a decision with confidence.
