Medicare Advantage vs. Medicare Supplement in Fort Myers: A 2027 Local Cost Comparison

Medicare Advantage (Part C) replaces Original Medicare with a private plan that often has a $0 premium and bundles in drug coverage, but uses a network and can leave you with thousands in out-of-pocket costs in a hard year. Medicare Supplement (Medigap) pairs with Original Medicare, lets you see any provider nationwide who accepts Medicare, and covers most out-of-pocket costs for a monthly premium. Below are the 2027 numbers for Lee, Collier and Charlotte counties, so you can compare with real local figures.

How Medicare Advantage Works

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 yearly in-network out-of-pocket spending; for 2027 the federal ceiling is $9,850.

How Medicare Supplement (Medigap) Works

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 stand-alone Part D plan.

2027 Medicare Advantage in Southwest Florida, by the Numbers

Medicare Advantage is a crowded market here. These are the plans listed in CMS’s 2027 plan data for our three counties:

Two things stand out. First, a $0 premium is the norm, not a special deal: most plans for people without Medicaid charge nothing beyond your Part B premium, and some include a “Part B giveback” that lowers your Part B premium (up to $200 a month on one Lee County plan). Second, the out-of-pocket ceilings are high. Half of the plans open to everyone in Lee County let your in-network costs reach $6,725 or more in a bad year.

What a Year Could Cost: Plan G vs. a Typical Local Advantage Plan

Here’s a simplified comparison for a 65-year-old non-tobacco woman in Fort Myers. Both paths also pay the Part B premium ($202.90 a month in 2026; the 2027 amount hasn’t been announced yet), so it’s left out of both columns.

Medical costs for the yearMedigap Plan G$0-premium Advantage plan with the median limit
PremiumAbout $2,916 (median $243/mo; $201 to $344/mo on file)$0
A healthy year: checkups and a few visitsPremium plus the $283 Part B deductible (2026)Copays for visits, often modest
A hard year: hospital stay, surgery or cancer careStill the premium plus $283: about $3,199 totalUp to $6,725 in network; out of network costs more or isn’t covered on an HMO
Prescription drugsSeparate Part D plan; out-of-pocket capped at $2,400 in 2027Usually included; out-of-pocket capped at $2,400 in 2027

Plan G figures are the median and range of sample rates on file with the Florida Office of Insurance Regulation for Lee County ZIP codes, effective November 1, 2026. Advantage figures are the median in-network maximum for Lee County plans open to everyone. Your actual costs depend on your plan, age, ZIP code and the care you use. Not a quote.

The pattern is simple. In a healthy year, the Advantage plan usually costs less. In a year with serious care, Plan G usually costs less, often by thousands of dollars, and you know the worst case on day one. Nobody knows in advance which kind of year they’ll have, which is why this choice is really about how much risk you’re comfortable carrying.

What the Numbers Don’t Show

  • Networks and approvals. With Advantage, you use the plan’s network, and many services need prior authorization. Before choosing a plan, check that your doctors and the hospitals you’d use, whether Lee Health, NCH or another system, are in that plan’s network for 2027, since networks can change year to year.
  • Time away from Florida. If you spend summers up north, an HMO generally covers only emergency and urgent care outside its service area. Medigap works the same everywhere in the U.S.
  • Extras. Advantage plans often include dental, vision, hearing aids, fitness programs or a Part B giveback. Medigap doesn’t, though you can buy stand-alone dental and vision coverage.
  • Getting back to Medigap later. If you choose Advantage and later want a Medigap plan, Florida companies can generally ask health questions and turn you down. The main exception is the federal “trial right”: if you join Advantage for the first time, you have 12 months to change your mind and get Medigap without health questions in certain situations.

Common Mistakes People Make

  • Choosing on premium alone without looking at the out-of-pocket maximum.
  • Assuming you can have both; you choose one path or the other.
  • Not checking that current doctors and prescriptions are covered by an Advantage plan’s network and formulary.
  • Letting the six-month Medigap enrollment window pass without deciding, then finding Medigap is harder to get later.
  • Comparing only Advantage plans during the October 15 to December 7 enrollment period without also pricing Medigap.

Common questions

CMS 2027 plan data lists 67 Medicare Advantage plans in Lee County, 59 in Collier and 62 in Charlotte. About half of them are Special Needs Plans that only people with Medicaid, certain chronic conditions or a nursing-home stay can join. Use Medicare.gov to see exactly which plans are offered in your ZIP code.

No premium is charged beyond your Part B premium, but you pay copays and coinsurance as you use care, up to the plan’s yearly out-of-pocket maximum. For 2027 Lee County plans open to everyone, that maximum ranges from $2,750 to $9,850 in network, with a median of $6,725.

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.
