What Both Plans Are Trying to Do

Original Medicare (Parts A and B) covers a lot — but not everything. There are deductibles, copays, and no cap on your out-of-pocket costs. Both Medicare Advantage and Medigap exist to fill those gaps. They just do it in very different ways.

Medicare Advantage (Part C): The All-in-One Approach

Medicare Advantage plans are offered by private insurance companies approved by Medicare. Instead of getting your benefits directly from the government, you get them through the plan — which typically bundles Part A, Part B, and usually Part D drug coverage together.

Most Advantage plans have a $0 or very low monthly premium. Many include extras like dental, vision, hearing, and fitness benefits. That sounds great — and for the right person, it is.

Here’s the trade-off: Advantage plans use networks. HMO plans require you to see in-network providers and get referrals for specialists. PPO plans give you more flexibility but still have in-network and out-of-network cost tiers. If your doctors aren’t in the network, you may have to switch or pay significantly more.

Advantage plans also have copays for services — $10 here, $45 there, $350 for a hospital stay. Most plans have an annual out-of-pocket maximum (in 2026, the cap is $9,350 for in-network costs), which provides a ceiling but can still be significant if you’re a heavy user of healthcare.

Who Medicare Advantage tends to work best for:

•      People who are relatively healthy and don’t use the healthcare system heavily

•      People on a tight budget who need a low or $0 premium

•      People whose doctors are already in-network

•      People who want extras like dental and vision bundled in

Medigap (Medicare Supplement): The Freedom Approach

Medigap plans work alongside Original Medicare rather than replacing it. You keep Medicare as your primary insurance, and Medigap pays some or all of the gaps — deductibles, copays, coinsurance — depending on which plan letter you choose.

The most popular plans in Florida are Plan G and Plan N.

Plan G covers nearly everything Original Medicare doesn’t, except the Part B deductible ($240 in 2026). After that deductible, most of your costs are $0 for the rest of the year.

Plan N is similar but has small copays ($20 for office visits, $50 for ER visits that don’t result in admission) and doesn’t cover Part B excess charges.

The big difference with Medigap: you can see any doctor in the country who accepts Medicare. No networks, no referrals, no prior authorizations. If a doctor takes Medicare, your Medigap plan works there.

The trade-off is cost. Medigap premiums in Florida for a 65-year-old typically run $120–$200/month depending on the plan and carrier. You’ll also need a separate Part D plan for drug coverage ($0–$60/month). So your total monthly investment is higher — but your out-of-pocket costs when you actually use care are much lower and far more predictable.

Who Medigap tends to work best for:

•      People who use the healthcare system regularly

•      People with ongoing health conditions or specialists they see frequently

•      People who travel frequently and want nationwide coverage

•      People who value predictability and don’t want surprise bills

•      People who want to avoid networks and referral requirements

The Florida-Specific Angle

In the Tampa Bay area, network quality matters. Pinellas and Hillsborough counties have excellent hospital systems — BayCare, AdventHealth, HCA Florida — and most are well-represented in major Advantage plan networks. That’s a point in favor of Advantage for local residents.

However, if you spend significant time traveling, have a specialist you love who’s out of network, or split time between Florida and another state, Medigap’s nationwide portability becomes a serious advantage.

The 3 Questions to Ask Yourself

•      How often do I use the healthcare system? If you’re healthy and rarely see doctors, Advantage’s lower premium may make more financial sense. If you have ongoing conditions, Medigap’s predictability protects you.

•      Do my current doctors accept Medicare? If yes, and they’re in your desired Advantage plan’s network, you’re likely fine either way. If your doctors are out-of-network, Medigap gives you freedom to keep them.

•      What’s more important to me — a lower monthly premium or lower costs when I use care? This is ultimately a budgeting question. Advantage front-loads the savings. Medigap back-loads them.

One More Thing: Switching Later Is Harder Than You Think

During your first 6 months on Medicare Part B, you have a Medigap Open Enrollment Window — meaning insurance companies must sell you any Medigap plan at standard rates, no health questions asked. After that window closes, switching to Medigap typically requires medical underwriting. This is exactly why the initial decision matters so much — and why it’s worth talking to an independent broker before you enroll.

The Bottom Line

Neither plan is universally better. The key is figuring out which one fits your situation. That’s what I do every day for people across Pinellas, Hillsborough, and Pasco counties — compare both options side by side, explain the real trade-offs, and help you make the decision that fits your health, your budget, and your life.
