Medigap Plan G vs. Medicare Advantage Plans in Florida

The Actual Tradeoff

Plan G is generally a fit for people who prioritize broad provider access and predictable Medicare cost-sharing and can afford the additional premium. Medicare Advantage can make more sense for people who prioritize lower monthly premiums and bundled benefits and are comfortable working within a plan's network and cost-sharing rules.

These are two fundamentally different ways of receiving Medicare benefits, not a better-versus-worse comparison.

Plan G works alongside Original Medicare with no provider network, in exchange for a higher premium. Medicare Advantage replaces Original Medicare with a private plan that usually has a lower premium, a provider network, and its own cost-sharing and approval rules.

Plan G: How It Works

Medigap Plan G supplements Original Medicare — it doesn't replace it. Medicare pays its share of your care first, and Plan G pays most of what's left, according to standardized benefits set by the federal government.

How Plan G Works

Plan G is one of several standardized Medicare Supplement (Medigap) plan letters. Private insurance companies sell it, but they can't change what it covers — that's set by CMS, so a Plan G policy from one company covers the same Medicare cost-sharing as a Plan G policy from any other company. You keep Medicare Part A and Part B exactly as they are — Plan G works alongside your Medicare, not in place of it.

Original Medicare pays its share of a Medicare-approved service first. Plan G then pays most of what Medicare doesn't — generally without you filing any paperwork, since the provider bills Medicare and Medicare forwards the claim to your Plan G insurer automatically. There's no separate approval step from the Medigap insurer before you receive care, and no referral needed to see a specialist. You can use any doctor, specialist, or hospital nationwide that accepts Medicare — Plan G doesn't use a provider network. This matters most for people who travel, split time between Florida and another state, or want the flexibility to see a specialist without a referral.

Coverage, Cost, and Prescription Drugs

After you've met the annual Part B deductible, Plan G covers the Part A hospital deductible, Part A and Part B coinsurance, skilled nursing facility coinsurance, and Part B excess charges — the extra amount some providers can charge above what Medicare approves. It also covers 80% of foreign travel emergency care up to plan limits, after a separate $250 deductible. Plan G does not cover the Part B deductible itself, prescription drugs, or routine dental, vision, or hearing care.

You pay the Plan G premium, your Medicare Part B premium, and the annual Part B deductible ($283 in 2026). After that, your Medicare-approved cost-sharing is minimal for the rest of the year. See our full Plan G in Florida guide for current sample rates.

Plan G doesn't include prescription drug coverage, so most people who choose it pair it with a standalone Part D plan, which adds its own monthly premium. Going without creditable drug coverage for too long can result in a late-enrollment penalty added to your Part D premium later.

Your Plan G premium can still rise due to companywide rate increases, medical cost inflation, or the insurer's claims experience. Florida's issue-age rating rule protects against one specific thing — your rate increasing simply because you had a birthday — not against all future increases.

Plan G: Get vs. Give Up

If Plan G's premium is the main obstacle, Plan N is a lower-premium Medigap option worth comparing before ruling out Medigap entirely.

Medicare Advantage: How It Works

Medicare Advantage is an alternative way of receiving your Part A and Part B benefits — through a Medicare-approved private plan, not a supplement to Original Medicare.

How Medicare Advantage Works

When you enroll in a Medicare Advantage plan, you're still in the Medicare program, but the private plan — not Original Medicare directly — administers your Part A and Part B benefits, and usually your Part D drug coverage too. See our full Medicare Advantage Plans guide for more on how these plans work generally.

You generally see providers within the plan's network, and the plan reviews and pays claims according to its own rules rather than Original Medicare's. Most Florida Medicare Advantage plans are HMOs or PPOs. HMO plans generally require you to choose a primary care provider and get a referral to see a specialist, and typically don't cover non-emergency care outside the network. PPO plans usually don't require referrals and may cover out-of-network care, but at higher cost-sharing than staying in-network.

Many plans also require prior authorization — the provider must get the plan's approval before certain services are covered. This is an extra step that doesn't exist under Original Medicare or Plan G, and it can occasionally lead to delays or denials that require an appeal.

Costs, Drugs, and Extra Benefits

Many plans have a low or $0 monthly premium, but you'll typically pay a copay or coinsurance for most visits and services. Your total out-of-pocket costs for the year are capped by the plan's annual out-of-pocket maximum, which is set within a CMS-mandated limit that changes each year.

Most Medicare Advantage plans in Florida bundle Part D drug coverage into the same plan (sometimes called MAPD). What you pay for a given medication depends on the plan's formulary and drug tier, which can change from year to year. Some plans also include benefits Original Medicare doesn't cover, such as dental, vision, hearing, or fitness programs — some Florida plans include a grocery allowance or transportation benefit. These vary significantly by plan and county — what's true of one Florida Medicare Advantage plan isn't necessarily true of another.

Plans, networks, formularies, and extra benefits can change from one plan year to the next. Review your plan's Annual Notice of Change every fall to see what's different for the coming year.

What Florida Beneficiaries Should Consider

Medicare Advantage Networks Can Change

Medicare Advantage networks, formularies, and plan availability in Florida have changed from year to year, which has real consequences for beneficiaries mid-treatment.

In our experience working with Florida clients, we've seen situations where a Medicare Advantage plan exited a county, a hospital system or physician group left a plan's network, or a formulary change affected a client's medication coverage — sometimes with limited notice. A few examples from recent years:

• Southwest Florida — Florida Blue and Lee Physician Group. A contract dispute between Florida Blue's Medicare Advantage plans and Lee Physician Group affected which patients could continue seeing their existing physicians in-network.
• Southwest Florida — UnitedHealthcare and Lee Health. A separate network dispute between UnitedHealthcare's Medicare Advantage plans and Lee Health affected in-network access to Lee Health's hospitals and providers for affected members.
• Northwest Florida — Wellcare and Baptist Health Care. A network dispute between Wellcare's Medicare Advantage plans and Baptist Health Care affected in-network access to Baptist's facilities and physicians for affected members.

These situations are disruptive because switching Medicare Advantage plans mid-year isn't always possible outside a Special Enrollment Period, and switching to a Medigap plan afterward may require medical underwriting.

To be clear, this isn't unique to Medicare Advantage — Plan G isn't immune to disruption either. A provider could stop accepting new Medicare patients, or a carrier's rate increases could make the premium unaffordable over time, forcing a difficult decision about whether to keep the plan.

If You Split Time Between Florida and Another State

Snowbirds face a different set of tradeoffs than full-time Florida residents, depending on which option they choose.

With Plan G and Original Medicare, you can see any provider nationwide who accepts Medicare — your coverage works the same whether you're in Florida or another state, with no separate network to check.

A Medicare Advantage HMO is generally tied to its Florida service area, so care received while you're away may not be covered except for genuine emergencies. A Medicare Advantage PPO may offer some out-of-network coverage outside Florida, but the cost-sharing and rules for using it vary by plan.

If you're splitting time between Florida and another state and considering Medicare Advantage, check whether your specific plan covers the providers you'd use in both locations — not just the network in Florida.

Your County Changes Your Medicare Advantage Options

Medicare Advantage plans are approved and priced by county, so the specific plans, premiums, and extra benefits available to you depend on where in Florida you live — a plan sold in one county may not be offered in a neighboring one. Plan G's premium also varies by ZIP code, but the coverage itself doesn't change based on where you live in Florida.

Cost Comparison

Comparing costs means comparing a predictable premium against a variable one — not simply which number is smaller.

Sample Florida Blue premiums obtained through Medicare.gov for a female, non-tobacco applicant. Not statewide averages — your actual rate depends on your age, ZIP code, sex, tobacco use, and insurance company.

A Real Florida Medicare Advantage Example

This is an example quote, not a representative statewide figure. Costs, copays, and the out-of-pocket maximum vary by plan and by county.

Even a $0-premium plan isn't free — the specialist, ER, and hospital copays above are real out-of-pocket costs that don't exist under Plan G once you've met the Part B deductible. The tradeoff is a $0 monthly premium against per-visit cost-sharing, capped by the annual out-of-pocket maximum.

Medicare Advantage premiums, copays, and out-of-pocket maximums vary significantly by plan and county — get a quote for a specific plan in your ZIP code rather than relying on this single example.

The honest comparison isn't "which premium is lower" — it's premium plus expected cost-sharing plus your tolerance for unpredictable bills, for both options, in your specific county.

Who Each Option May Fit

Plan G May Fit You If You:

• Travel frequently or split time between Florida and another state
• Want the fewest bills to manage and minimal cost-sharing after the deductible
• Can comfortably afford the higher combined Plan G + Part D premium
• Have providers who may not be in every Medicare Advantage network

If Plan G's premium is the main obstacle, Plan N and High Deductible Plan G are lower-premium Medigap options worth comparing before choosing Medicare Advantage on price alone.

Medicare Advantage May Fit You If You:

• Want to minimize your monthly premium
• Would benefit from bundled extras like dental, vision, or hearing coverage
• Are comfortable with your specific plan's network and prior authorization rules
• Want prescription drug coverage included in the same plan

An Agent's Perspective

Bottom Line

Neither option is universally best.

Plan G tends to suit people who want predictable bills, broad provider access, and can afford the higher combined premium. Medicare Advantage tends to suit people who prioritize a lower monthly cost and bundled extras, and who are comfortable working within a specific plan's network and approval rules.

Compare actual costs for your county — a real Plan G premium against a real Medicare Advantage plan's premium, copays, and network — rather than assuming one is broadly better than the other.
