Florida Medicare Advantage vs Medigap — Total Annual Cost Comparison 2026

By the Florida Plan Finder Team · Licensed Florida Health Insurance Producer · NPN #21249133 · Last Updated: May 2026

Key Takeaways

Medicare Advantage wins on premium — often $0/month — but your out-of-pocket risk can reach $3,350–$9,350 if you use heavy care.
Medigap Plan G has a higher monthly premium (~$130–$175 in FL) but caps your out-of-pocket at the $257 Part B deductible per year.
A single hospital admission typically makes Medigap Plan G the lower-cost option for that year compared to MA cost-sharing.
Medicare Advantage plans are network-restricted; Medigap is accepted by any Medicare provider nationwide — critical for Florida snowbirds and travelers.
Switching from MA back to Medigap in Florida requires health underwriting outside of guaranteed issue periods.
For low-income beneficiaries, Extra Help (LIS) and D-SNPs often make MA the clear financial winner.

The single most consequential Medicare decision most Florida retirees make is not which drug plan to choose or whether to use a particular hospital — it is the fundamental choice between Medicare Advantage and Medigap (Medicare Supplement). This is a structural decision that affects every aspect of your healthcare experience: how much you pay, which doctors you can see, how predictable your costs are, and how much flexibility you have when traveling or moving. No universal right answer exists, but the tradeoffs are clear enough to analyze systematically — and that is exactly what this guide does.

1. The Core Tradeoff

Medicare Advantage and Medigap represent two fundamentally different insurance philosophies. Medicare Advantage transfers financial risk to the beneficiary at the point of care — you pay low (or no) premiums, but every service involves a copay, coinsurance, or deductible, and costs can accumulate significantly if you have a bad health year. Medigap front-loads cost as a predictable monthly premium, then covers nearly all point-of-care cost-sharing — so your expenses are budgetable regardless of how sick you get.

Feature	Medicare Advantage (MA)	Medigap Plan G
Additional monthly premium (beyond Part B)	Often $0; some plans $20–$100+	$130–$175/month (FL, age 65)
Point-of-care costs	Copays, coinsurance, deductibles per service	$0 after $257 Part B deductible
Maximum annual out-of-pocket	$3,350–$9,350 (in-network)	$257 (Part B deductible only)
Provider network	HMO or PPO — restricted to network	Any provider accepting Medicare nationwide
Drug coverage	Usually included (MAPD)	Requires separate Part D plan (~$15–50/mo)
Referrals required	Yes (HMO); sometimes (PPO)	No — direct specialist access
Extra benefits (dental, vision, OTC)	Often included	None — Medicare only

2. Annual Total Cost Model — 3 Use Scenarios

The following models compare a typical 65-year-old Florida resident enrolled in a $0-premium MA plan vs. Medigap Plan G (assume $155/month premium) plus a $25/month Part D plan. Part B premium ($185/month) is the same in both scenarios.

Scenario A: Healthy Year (Primary Care + 2 Specialist Visits, No Hospital)

Cost Item	Medicare Advantage ($0 premium)	Medigap Plan G + Part D
Additional monthly premium × 12	$0	$2,160 ($155 + $25 × 12)
Part B deductible	Included in copays	$257
Primary care visits (3 × $10 copay)	$30	$0
Specialist visits (2 × $40 copay)	$80	$0
Lab work / imaging	~$50 coinsurance	$0
Estimated Annual Total	~$160	~$2,417

MA wins by roughly $2,250 in a healthy year.

Scenario B: Moderate Use (Surgery, 3-Night Hospital Stay, Follow-up Rehab)

Cost Item	Medicare Advantage	Medigap Plan G + Part D
Additional monthly premium × 12	$0	$2,160
Part B deductible	Included	$257
Hospital admission (3 nights × $350/night copay typical)	$1,050	$0 (Plan G covers Part A deductible)
Surgery facility copay	$250–500	$0
Multiple specialist visits + PT	$300	$0
Estimated Annual Total	~$1,650–$1,900	~$2,417

Roughly even — MA may still narrowly win, but the predictability advantage shifts to Medigap.

Scenario C: Heavy Use (Extended Hospital Stay, SNF, Oncology or Cardiac Care)

Cost Item	Medicare Advantage	Medigap Plan G + Part D
Additional monthly premium × 12	$0	$2,160
Part B deductible	Included	$257
Hospital + SNF + specialist cost-sharing	Up to MOOP: $3,350–$9,350	$0
Worst-case Annual Total	$3,350–$9,350	$2,417

Medigap wins decisively in any serious illness year. The MA MOOP can exceed Plan G's total annual cost by 4–5x.

3. MOOP and Worst-Case Risk Analysis

The Maximum Out-of-Pocket (MOOP) is the most important number to understand when evaluating Medicare Advantage. Once you hit the MOOP, MA pays 100% of covered in-network services for the rest of the year. But reaching the MOOP means you have already spent $3,350 to $9,350 out of pocket in a single year — in addition to your Part B premium.

The MOOP is not a ceiling on all costs. MA MOOPs apply only to in-network covered services. Out-of-network costs on a PPO plan have a separate (higher) limit. Prescription drugs have separate cost-sharing. Non-covered services have no MOOP protection.

For Florida's Medicare population, which has a high incidence of chronic conditions, cardiac disease, cancer, and diabetes, the realistic probability of a serious health event over a 5-year horizon is substantial. From a risk management perspective, Medigap Plan G functions as catastrophic cost protection with a known, fixed annual budget.

4. Provider Access and Network Restrictions

Medicare Advantage plans contract with specific providers. HMO plans require you to use network providers for all non-emergency care. PPO plans allow out-of-network use but at higher cost-sharing. If your preferred physicians, hospital, or specialists are not in the MA plan's network, you either switch providers or pay out-of-network rates — or leave the plan during the next enrollment window.

Medigap works everywhere Medicare does. Any provider who accepts Medicare — from Jacksonville to Mayo Clinic in Rochester to MD Anderson in Houston — must accept your Medigap Plan G. You never need a referral and there is no network to navigate. For Floridians with complex conditions who want access to leading academic medical centers, this is a decisive advantage.

5. Florida Geographic Considerations

Florida's geography creates meaningful differences in how each plan type performs:

Florida Area	MA Network Quality	Implication
Miami-Dade, Broward, Palm Beach	Excellent — many competing plans, large networks	MA is a viable choice; strong competition keeps quality up
Tampa Bay, Orlando	Good — multiple plans, broad networks	Both MA and Medigap work well; cost comparison drives decision
Jacksonville, Gainesville	Good in metro areas	MA reasonable in city; Medigap better if you use UF Health / Mayo
Rural North/Central FL, Panhandle	Limited — fewer plans, thinner networks	Medigap often better fit; fewer MA options, provider gaps
Snowbirds (part-year FL residents)	Poor — out-of-state HMO coverage limited to emergencies	Medigap clearly preferred; national coverage essential

6. Income Effects: Extra Help, LIS, and IRMAA

Extra Help / Low Income Subsidy (LIS): For Medicare beneficiaries with income below roughly 150% of the federal poverty level, the Extra Help program subsidizes Part D drug costs and often eliminates plan premiums entirely. A dual-eligible beneficiary on a D-SNP with LIS typically pays $0 for the Medicare Advantage plan, $0 or near-zero for drugs, and may have Medicaid pay the Part B premium. For this population, MA with Extra Help almost always outperforms Medigap financially.

IRMAA: High earners pay IRMAA surcharges on Part B and Part D regardless of whether they choose MA or Medigap. IRMAA is assessed on Part B, not on the supplemental plan itself. A beneficiary paying $480.90/month for Part B under IRMAA will owe that same amount whether on MA or Medigap. The choice between MA and Medigap does not change IRMAA liability.

7. When Medicare Advantage Makes the Most Sense

You are in good health and expect low utilization year-over-year
You live in an urban Florida county with robust MA networks (Miami, Tampa, Orlando)
Your preferred physicians and hospital are in the plan's network
You qualify for Extra Help / LIS and a $0-premium MAPD covers your drugs well
You want extra benefits — dental, vision, OTC allowance — that Medigap does not offer
You are budget-constrained and cannot afford Medigap premiums plus a Part D plan
You stay in Florida year-round and do not travel extensively to other states

8. When Medigap Plan G Makes the Most Sense

You have one or more chronic conditions that generate regular specialist visits, procedures, or hospitalizations
You split time between Florida and another state (snowbird) — Medigap covers you nationwide
You want direct specialist access without referrals and no network restrictions
You are planning major elective surgery and want to choose your surgeon without network constraints
You have high income (can budget predictable premiums) and want financial certainty
You live in rural Florida where MA networks are thin or plan options are limited
You want to use academic medical centers or specialty hospitals outside of Florida

The switching trap: Many people choose MA for the low premium at 65 when healthy, then want to switch to Medigap when health declines. In Florida, this switch requires medical underwriting — and insurers can charge significantly higher premiums or decline coverage based on pre-existing conditions. If Medigap is the long-term plan, enroll during the guaranteed issue window at 65.

Frequently Asked Questions

What is the maximum out-of-pocket limit for Medicare Advantage plans in Florida?

For 2026, CMS set the MA MOOP cap at $9,350 for in-network services and $14,000 for combined in-network and out-of-network. Individual plans may set lower MOOPs — many Florida plans offer $3,350–$5,000 in-network MOOPs — but the federal ceiling is $9,350 in-network. With Medigap Plan G, your out-of-pocket is capped at the $257 Part B deductible per year.

Can I switch from Medicare Advantage back to Medigap in Florida?

Yes, but it requires medical underwriting outside of guaranteed issue periods. In Florida, Medigap insurers can review your health history and may charge higher premiums or deny coverage if you have pre-existing conditions. The exception is your initial enrollment at 65 (6-month open enrollment) or a qualifying Special Enrollment Period when you lose involuntary coverage.

Does Medicare Advantage include Part D drug coverage?

Most Medicare Advantage plans in Florida include integrated Part D drug coverage (called MAPD plans). With Medigap, you must purchase a separate standalone Part D plan, adding approximately $15–50/month depending on the plan and your medications.

Is Medicare Advantage or Medigap better for Florida snowbirds?

Medigap is almost always the better choice for snowbirds who split time between Florida and another state. Medigap Plan G is accepted by any provider nationwide that accepts Medicare. Medicare Advantage plans are network-based — HMO plans rarely cover out-of-area services except for emergencies, and PPO plans have higher cost-sharing out of network.

How does Extra Help (LIS) affect the Medicare Advantage vs Medigap decision?

Extra Help (Low Income Subsidy) dramatically reduces Part D drug costs and often eliminates premiums entirely for qualifying Medicare Advantage plans. For beneficiaries with Extra Help, a $0-premium MA plan with drug coverage often represents significantly better value than a Medigap plan with a separate Part D premium. Extra Help is worth applying for if your income is below roughly 150% of the federal poverty level.
