Medicare is the federal health insurance program for people age 65 and older (and some younger adults with disabilities). It has four parts — A, B, C, and D — and you enroll during a 7-month window around your 65th birthday. In Florida, most beneficiaries pair Original Medicare (A+B) with either a Medigap supplement or a Medicare Advantage plan.
Medicare is the federal health insurance program for Americans 65 and older. It has four parts — A, B, C, and D — and for most Jacksonville residents, the real question isn't whether you qualify. It's which combination of those parts actually fits your health, your doctors, and your budget. This guide walks through all of it in plain language.
If you’re approaching 65 in Duval County, newly on Medicare and reconsidering your plan, or an adult child helping a parent in Northeast Florida navigate this for the first time — you’re in the right place. No sales pitch, no jargon, just the structure of Medicare and the decisions you need to make about it.
Costs, thresholds, and enrollment rules in this guide reflect official CMS figures as of April 23, 2026. Medicare premiums, deductibles, and income thresholds are updated annually — verify current amounts on medicare.gov or with a licensed broker before making enrollment decisions. See Sources at the end for CMS references.
What is Medicare, and who qualifies?
Medicare is the federal health insurance program run by the U.S. Centers for Medicare & Medicaid Services. It serves three main groups:
- Adults age 65 and older who are U.S. citizens or legal permanent residents of at least five years
- Adults under 65 who have received Social Security Disability Insurance (SSDI) for 24 months
- People of any age with End-Stage Renal Disease (ESRD) or ALS
The overwhelming majority of Medicare beneficiaries in Jacksonville qualify through age 65. If you’ve worked and paid Medicare taxes for at least 10 years (40 quarters), you earn premium-free Part A coverage at 65. Your spouse’s work history can also qualify you, even if you haven’t worked enough quarters yourself.
Medicare is not the same as Medicaid. Medicaid is a state-run program for people with limited income and assets; in Florida it’s administered by the Agency for Health Care Administration. Some people qualify for both — that’s called “dual eligibility” — but for most Jacksonville seniors turning 65, Medicare is the primary program we’re talking about.
What are the four parts of Medicare?
Medicare has four parts. Each covers a different category of care, and most people end up with a combination — not just one.
- Inpatient hospital stays
- Skilled nursing facility care
- Hospice care
- Some home health care
- Doctor visits and outpatient care
- Preventive services
- Durable medical equipment
- Some mental health services
- Private-insurer alternative to Original Medicare
- Bundles A, B, and usually D
- Often includes DVH + fitness extras
- Uses a network of providers
- Standalone prescription plan
- Works alongside Original Medicare
- Formulary tiers determine your cost
- Monthly premium varies by plan
The two paths most Jacksonville beneficiaries choose
Once you understand the parts, the practical choice narrows quickly:
Path 1 — Original Medicare + Medigap + Part D. You keep Parts A and B, add a Medigap supplement to cover deductibles and coinsurance, and buy a standalone Part D drug plan. Higher monthly cost, very predictable out-of-pocket expenses, nationwide provider access.
Path 2 — Medicare Advantage. You replace Original Medicare with a private Part C plan that usually bundles drug coverage (MAPD). Lower monthly cost, network-based, more variability in out-of-pocket costs capped by a plan maximum.
These are the two roads. We’ll come back to them in detail.
When should I enroll in Medicare?
Enrollment timing is the single most common place Medicare beneficiaries in Northeast Florida lose money unnecessarily. Miss your window and you can pay permanent late-enrollment penalties on top of your premiums — not for one year, but for life.
Your Initial Enrollment Period (IEP)
Your IEP is a 7-month window around your 65th birthday:
3 months before your 65th birthday month
Coverage can start the first day of your birthday month if you enroll now.
Your 65th birthday month
Coverage starts the first day of the following month.
3 months after your 65th birthday month
Coverage starts the first day of the month after you enroll — there can be a gap.
If you’re already receiving Social Security benefits when you turn 65, you’re automatically enrolled in Parts A and B. If you’re not receiving Social Security yet, you have to enroll yourself at ssa.gov/medicare, through your local Social Security office, or by calling SSA.
Special Enrollment Periods (SEPs)
If you’ve had employer health coverage past 65 — still working, or on a spouse’s plan — you get a Special Enrollment Period when that coverage ends. SEPs let you enroll without the late-enrollment penalty, but the timing is strict: typically 8 months from when the employer coverage ends for Part B, and 63 days for Part D.
The Annual Enrollment Period (AEP)
October 15 through December 7 every year. During AEP, existing Medicare beneficiaries can switch Medicare Advantage plans, switch Part D plans, or move between Original Medicare and Medicare Advantage. AEP changes take effect January 1 of the following year.
The Medigap Open Enrollment Period
Separate from AEP and absolutely critical: your Medigap Open Enrollment is a one-time 6-month window that starts the month you are 65 or older and enrolled in Part B (whichever happens later). During this window, Medigap insurers cannot refuse you or raise your rate based on pre-existing conditions. After that window closes, Medigap policies become medically underwritten in most cases — meaning a health condition can make a policy expensive or unavailable. Important for anyone delaying Part B past 65 because of employer coverage: your OEP doesn’t start until the month you finally enroll in Part B — not at 65. This is the single most important enrollment window most Jacksonville seniors don’t know about until it’s too late.
Medicare Advantage vs. Medigap: the biggest choice you’ll make
For most people turning 65 in Jacksonville, this is the decision that defines their Medicare experience: add a Medigap supplement to Original Medicare, or replace it with Medicare Advantage.
| Feature | Original Medicare + Medigap | Medicare Advantage |
|---|---|---|
| Monthly premium | Part B ($202.90) + Medigap ($100–$300) + Part D ($0–$70) | Part B ($202.90) + MA plan (often $0) |
| Provider network | Any provider that accepts Medicare — nationwide | Network only (HMO/PPO) — varies by plan |
| Referrals for specialists | Not required | Often required (HMO plans) |
| Out-of-pocket predictability | Very high — Medigap covers almost everything | Lower monthly but more variable; capped by annual max |
| Prescription drugs | Separate Part D plan required | Usually included (MAPD) |
| Dental, vision, hearing | Not covered — buy standalone DVH or pay out of pocket | Often included (varies by plan) |
| Travel outside Florida | Seamless — any Medicare provider nationwide | Limited — in-network usually only in-area |
Neither option is better or worse universally. The right answer depends on your doctors, your budget, your health status, and how much you travel.
Medigap is often the better fit if you:
Medicare Advantage is often the better fit if you:
Jacksonville has a strong Medicare Advantage market because major health systems — Baptist Health, UF Health Jacksonville, Mayo Clinic Jacksonville, Ascension St. Vincent's — are all contracted with multiple MA carriers. That makes network-based plans practical here in a way they aren't in more rural Florida counties.
What does Medicare actually cost in Florida?
There’s no single Medicare bill — you’re paying for multiple coverages, and the total depends on the combination you choose. Here’s a realistic 2026 breakdown for a Jacksonville beneficiary.
| Coverage component | Typical 2026 monthly cost | Notes |
|---|---|---|
| Part A premium | $0 for most | If you didn't earn 40 quarters, you can buy in — $311 or $565/month depending on quarters |
| Part B premium | $202.90 standard | Higher for incomes above the IRMAA threshold |
| Medigap Plan G (typical in FL) | $120–$250 | Varies by age, tobacco use, and carrier |
| Part D (standalone) | $0–$70 | More if you take name-brand specialty drugs |
| Medicare Advantage (MAPD) | $0–$60 | $0-premium plans are common in Duval County |
| Dental / Vision / Hearing standalone | $20–$60 | Paired with Medigap; often bundled into MA plans |
IRMAA — Income-Related Monthly Adjustment Amount — is the income surcharge that bumps Part B (and Part D) premiums for higher-income beneficiaries. In 2026, it kicks in at an individual modified adjusted gross income above $109,000 (single) or $218,000 (married filing jointly). The exact thresholds are updated annually by the Social Security Administration.
The two realistic monthly totals for a typical Jacksonville Medicare beneficiary in 2026:
- Path 1 (Original + Medigap + D): roughly $325–$525/month total, with very low additional costs at the point of service
- Path 2 (Medicare Advantage): roughly $205–$265/month total, with copays and coinsurance on top when you use care
Neither is “cheaper” in absolute terms. Path 1 front-loads predictable costs; Path 2 spreads them across use of care.
How do I pick the right Medicare plan?
List your doctors and the drugs you take
Every good Medicare decision starts here. Write down every provider you want to keep and every prescription you fill regularly. These two lists drive every other decision.
Check networks against those doctors
If you're considering Medicare Advantage, verify every doctor on your list is in-network for each plan you're evaluating. Network membership changes annually — don't rely on last year's status.
Check formularies against those drugs
Every Part D and MAPD plan has a formulary — the list of drugs it covers, tiered by cost. A $0-premium plan that doesn't cover your maintenance drug on a preferred tier is more expensive than a $25-premium plan that does.
Calculate your realistic total annual cost
Premium × 12 + deductible + expected copays + prescription costs at your usage level. The cheapest-premium plan rarely wins this calculation — the math does.
Compare across multiple carriers
Florida's Medicare market has more than a dozen carriers. Seeing one plan isn't comparing — it's pitching. This is where an independent broker saves the most time.
You are not charged for working with an independent broker. Brokers are paid a commission by the insurance carrier when you enroll. The commission is the same across carriers, so there's no financial incentive for a broker to push you toward one plan over another.
The most expensive Medicare mistakes (and how to avoid them)
Late enrollment in Part B adds a 10% penalty for every 12 months you were eligible and didn't enroll — for life. Someone who delays Part B by 3 years pays ~30% more every month forever. Part D has a separate permanent penalty: roughly 1% of the national base beneficiary premium ($38.99 in 2026) for every month you went without creditable drug coverage, added to your Part D premium for the rest of your life.
Your one-time 6-month guaranteed-issue window starts when you enroll in Part B. Wait past it, and Medigap carriers can deny you or price you higher based on pre-existing conditions.
A $0-premium drug plan that doesn't cover your medications well can cost you thousands more per year than a $40-premium plan with a favorable formulary.
Every year, plans change — networks shrink, formularies drop drugs, copays increase. The plan that was right for you last year may be significantly worse this year. October 15 – December 7 is your window to check.
An agent who represents one carrier cannot recommend another carrier's plan, even when it's objectively better for you. Ask upfront: "Do you represent one insurance company, or are you an independent broker?"
How Duncan Market Insurance fits in
I’m Carolyn Duncan. I’ve been an independent insurance broker in Jacksonville for over 20 years, and Medicare is my core focus. Being independent means I’m not employed by any insurance carrier — I compare across all the major Medicare carriers serving Duval, St. Johns, Clay, Nassau, and Flagler counties and show you honest side-by-side comparisons based on the doctors and drugs you actually use.
You don’t pay anything for this. Not for the initial consultation, not for annual plan reviews, not for help during AEP. Insurance carriers pay brokers a commission when you enroll, and the commission is standardized — so there’s no financial reason for me to steer you toward one plan over another. My only incentive is keeping you as a client for life, which only happens if I help you get this right.
That’s what this guide is meant to do — give you the structure to ask the right questions. When you’re ready to map your specific doctors, drugs, and situation onto the actual plans available in Jacksonville, that’s what a consultation is for.
Ready to get Medicare right in Jacksonville?
Medicare doesn’t get simpler the longer you put it off — it gets more expensive. Whether you’re turning 65 in the next 6 months, on Medicare today and unsure if your plan still fits, or an adult child trying to help a parent navigate this, a 30-minute conversation will clarify more than hours of reading.
You’ll leave the consultation knowing: which of the two paths (Medigap or Advantage) fits your situation, which plans in Jacksonville match your doctors and prescriptions, and what your realistic monthly cost will be. No pressure, no pitch for a specific carrier, no charge.

Frequently asked questions
When should I enroll in Medicare if I'm turning 65 in Jacksonville?
Enroll during your Initial Enrollment Period — the 7-month window that starts 3 months before the month you turn 65, includes your birthday month, and ends 3 months after. Missing this window can mean permanent late-enrollment penalties on Part B and Part D, so start at least 3 months before your 65th birthday.
Do I need both Medicare Part A and Part B?
Most people need both. Part A (hospital) is premium-free if you or your spouse paid Medicare taxes for at least 10 years. Part B (medical) has a monthly premium but covers doctor visits, outpatient care, and preventive services. Skipping Part B while eligible usually triggers a lifelong late-enrollment penalty.
What's the difference between Medicare Advantage and Medigap in Florida?
Medicare Advantage (Part C) bundles A, B, and usually D into one plan from a private insurer — often with a $0 premium but a network and copays. Medigap supplements Original Medicare by covering deductibles, coinsurance, and gaps — with a higher monthly premium but very low out-of-pocket costs and nationwide provider access.
Does Medicare cover dental, vision, or hearing in Florida?
Original Medicare does not cover routine dental, vision, or hearing care. Many Medicare Advantage plans include limited DVH benefits. For broader coverage, you can buy a standalone dental/vision/hearing plan — a common pairing for Medigap enrollees who keep Original Medicare.
How much does Medicare cost in 2026?
Part A is premium-free for most people. The Part B standard premium is $202.90 per month in 2026, higher for incomes above the IRMAA threshold. Medigap premiums range roughly $100–$300/month depending on plan letter and age. Medicare Advantage premiums in Florida are often $0, with out-of-pocket costs capped by law.
