Quick Answer: Medicare Advantage (Part C) replaces Original Medicare with a private plan that often has a $0 premium and bundles in drug coverage, but requires you to use a network. Medicare Supplement (Medigap) pairs with Original Medicare, lets you see any provider nationwide who accepts Medicare, and covers most out-of-pocket costs, but costs a separate monthly premium and doesn’t include drug coverage. The right choice depends on your budget, health, travel habits, and how much cost predictability you want.
| Medicare Advantage | Medicare Supplement | |
| Monthly premium | Often $0, plus Part B ($202.90/mo in 2026) | Separate premium (Plan G averages ~$180/mo), plus Part B |
| Provider network | HMO or PPO network | Any provider nationwide who accepts Medicare |
| Drug coverage | Usually included (MAPD) | Not included — needs separate Part D plan |
| Extra benefits (dental/vision/hearing) | Often included | Not included |
| Cost predictability | Copays/coinsurance up to an annual out-of-pocket max | Covers most gaps — very predictable month to month |
| Best for | Budget-conscious, generally healthy, OK with a network | Frequent travelers, want predictable costs, don't mind a higher premium |
Medicare Advantage (Part C) plans are sold by private insurers approved by Medicare. When you enroll, the private plan takes over delivering your Part A and Part B benefits, and most plans bundle in Part D drug coverage and extras like dental, vision, and hearing. In exchange, you typically use a network of doctors and hospitals (HMO or PPO), and some services may require referrals or prior authorization. Every Medicare Advantage plan caps your annual out-of-pocket spending, which Original Medicare alone does not do.
Medicare Supplement plans don’t replace Original Medicare — they work alongside it. You keep Original Medicare (Parts A and B) and add a Medigap policy that pays some or all of the deductibles, copays, and coinsurance Original Medicare leaves you owing. Because you’re still on Original Medicare, you can see any provider in the country who accepts Medicare, with no network and no referrals. Medigap plans don’t include drug coverage, so most people pair one with a standalone Part D plan.
The two paths trade off in opposite directions. Medicare Advantage usually costs less month to month and bundles in extra benefits, but ties you to a network and means your costs can vary depending on how much care you use. Medicare Supplement costs more up front but makes your healthcare costs far more predictable and gives you the freedom to see any Medicare provider nationwide, which matters most if you travel, split time between states, or have specialists you don’t want to lose access to.
It depends on how much care you use in a given year. Medicare Advantage often wins on premium alone, especially with $0-premium plans. But if you have a high-cost health event, your total out-of-pocket costs on a Medicare Advantage plan can climb close to (or hit) the annual maximum, whereas a Medigap plan holds your costs steady no matter how much care you need. For light users of the healthcare system, Medicare Advantage is usually cheaper overall. For people who expect frequent specialist visits, procedures, or hospital stays, Medigap’s predictability often wins out even with the higher premium.
Because we’re not tied to one insurance company, we can walk you through Medicare Advantage and Medicare Supplement options side by side for your specific ZIP code, check your doctors and medications against plan networks and formularies, and help you weigh the trade-offs based on your actual health needs and budget — not just plan marketing.
No. You choose one path: either Original Medicare plus an optional Medigap policy, or a Medicare Advantage plan that replaces Original Medicare. You cannot be enrolled in both a Medicare Advantage plan and a Medigap policy at the same time.
Medicare Advantage usually has a lower (often $0) monthly premium, while Medigap has a higher premium but covers more of your out-of-pocket costs. Whether one is ‘cheaper’ overall depends on how much healthcare you use in a given year.
Yes, but outside your initial enrollment window, Medigap insurers in most states can use medical underwriting, meaning your health history could affect your eligibility or premium. Some situations, like moving or losing coverage, may qualify you for guaranteed-issue rights.
No. Medigap plans do not include drug coverage. Most people who choose Medigap also enroll in a standalone Medicare Part D prescription drug plan.
Most Medicare Advantage plans cover emergency and urgent care nationwide, but routine care outside your plan’s network usually isn’t covered. If you travel often or spend part of the year outside Southwest Florida, that’s worth weighing against Medigap’s nationwide provider access.
