Medicare Advantage vs. Medicare Supplement — Which Is Right for You in Florida?
This is the most important Medicare decision you'll make. Both options have real advantages depending on your health, your doctors, and your budget. Here's a straight-talk comparison from a licensed Florida advisor.
The short answer: Medicare Advantage offers lower premiums (often $0) with network restrictions. Medicare Supplement (Medigap) offers higher premiums with no network restrictions and more predictable costs. The right choice depends on your health, your doctors, and how you use healthcare.
Side-by-Side Comparison
| Feature | Medicare Advantage | Medicare Supplement |
|---|---|---|
| Monthly premium | Often $0 | $90–$180/mo (est.) |
| Network | In-network required | Any Medicare provider |
| Referrals | Required (HMO) | Not required |
| Drug coverage | Usually included | Separate Part D needed |
| Dental/Vision/Hearing | Usually included | Not included |
| Out-of-pocket maximum | Yes ($9,350 in 2026) | Varies by plan |
| Prior authorizations | Required for some services | Not required |
| Works nationwide | Emergency only | Yes — all 50 states |
| Changes annually | Yes — benefits, network, formulary | Premium increases with age |
| Best for | Healthy, budget-conscious, local care | Frequent care, travel, predictability |
When Medicare Advantage Makes More Sense
Medicare Advantage tends to be the better choice when:
- Your doctors and specialists are in the plan's network
- You want to minimize monthly premiums
- You want dental, vision, and hearing built in
- You are in relatively good health
- You primarily receive care in one geographic area
- You want drug coverage bundled in one plan
The risk: If you develop a serious condition and need frequent specialist visits, out-of-pocket costs can add up — up to the $9,350 out-of-pocket maximum.
When Medicare Supplement Makes More Sense
Medicare Supplement tends to be the better choice when:
- You want to see any doctor who accepts Medicare — no network
- You have ongoing health conditions requiring frequent care
- You travel frequently or spend time in multiple states
- You want predictable, fixed out-of-pocket costs
- You have specific specialists you don't want to change
- You want to avoid prior authorization delays
The trade-off:Higher monthly premium. No dental, vision, or hearing — you'll need standalone supplemental coverage for those.
The Cost Comparison — Running the Real Numbers
Most people focus on the monthly premium. The right comparison includes total annual costs.
Example (hypothetical Florida resident, age 68):
Medicare Advantage Plan
- Monthly premium:$0
- Annual deductible:$200
- Primary care copay:$5 × 12 visits = $60
- Specialist copay:$45 × 6 visits = $270
Medicare Supplement Plan G
- Monthly premium:$155 × 12 = $1,860
- Part B deductible:$257 (once per year)
- All other covered costs:$0
- Part D plan:$45 × 12 = $540
In this scenario, Medicare Advantage costs less.
Now the same person with a health event (hip replacement):
Medicare Advantage
- Surgery: $1,500 copay
- Rehab: $300 copay
- Follow-up specialist visits: $180
Additional cost: $1,980
Medicare Supplement Plan G
- All covered at $0 after Part B deductible
Additional cost: $0
With a health event, Supplement often wins. The right answer depends on your individual health situation — which is exactly what we help you figure out.
Can You Switch Between Them?
Yes — but the timing matters.
Switching from Supplement to Advantage:
Generally possible during AEP (Oct 15 – Dec 7) or OEP (Jan 1 – Mar 31).
Switching from Advantage to Supplement:
You may be subject to medical underwriting outside of guaranteed issue situations. If you're denied coverage or charged more due to health conditions, your options may be limited.
This is why the initial decision — made when you first turn 65 — is so important. Your Medigap Open Enrollment Period gives you guaranteed access to any Supplement plan. That window closes and does not reopen.
