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

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.

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)

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

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

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)

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.

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.

5. Florida Geographic Considerations

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

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
