Medicare in Jacksonville and Duval County, 2026: The Most Choice, the Widest Spread, and the Sorting Nobody Does For You

“What’s the most important question I should be asking about Medicare that I probably haven’t thought of yet?” That question was posted publicly on a consumer Medicare Q&A site, and in Jacksonville it has a specific answer. The question nobody asks is: how far apart are the plans I am choosing between? Not how many there are. How far apart.

Duval County has more Medicare plans on the shelf than anywhere else we work on the First Coast. That sounds like an advantage, and in some ways it is. It is also why two neighbours in Arlington can both enrol in a plan that costs nothing per month and end a bad year thousands of dollars apart. A big market is a wide market, and the market is not going to do the sorting for you.

What does the biggest Medicare market on the First Coast actually look like?

CMS publishes a landscape file every autumn with one row for every plan offering in every county. For contract year 2026, Duval County has 90 rows: 46 Medicare Advantage and MA-PD records plus 44 Special Needs Plan records. Those rows come from 12 parent organizations — CVS Health Corporation, Centene Corporation, Devoted Health, Elevance Health, Gold Kidney Health Plan, Guidewell Mutual Holding Corporation (Florida Blue), Health Care Service Corporation, Humana, Independent Living Systems, Longevity Health Founders, Mitchell Family Office and UnitedHealth Group.

Twelve companies is a crowd. Nassau County, forty minutes north, has six. St. Johns, forty minutes south, has seven. Clay has ten. Only Broward, at 16, fields more, and Broward has roughly twice Duval’s population.

Read the last two columns together. Duval has the deepest bench of carriers on the First Coast and the lowest mean star rating of the five counties in our data. Sixty-one of the 84 rated Duval records reach 4 stars or better — almost exactly Clay’s count on a smaller file. The average is pulled down not by a collapse at the top but by a longer tail at the bottom.

Why does more competition produce a lower average rating?

Because carriers do not enter a market by being good. They enter it by being able to. A metro of a million people with a large Medicare and Medicaid population supports plan designs that a county of 94,000 will not, so smaller regional and specialist organisations file plans in Jacksonville that never appear in Fernandina Beach. Some are excellent. Some are new, thin, or aimed at a population you are not in. All of them land in the same envelope on your kitchen table, and in a wide market the floor drops faster than the ceiling rises.

Star ratings are a contract-level measure of things like customer service, complaint rates, screening and medication management, published by CMS on the same basis for every plan in the country. That makes them the one quality figure you can compare across a whole county without an insider’s knowledge. A 4.19 average with 61 of 84 records at 4 stars or better says good plans are the majority here, and that the minority is large enough to matter if you pick without looking.

One thing the chart cannot show. A star rating describes the contract, not your experience of it. A 4.5-star plan whose network excludes your cardiologist is worse for you than a 3.5-star plan that includes him. Use the rating to set the order you look in, not to decide.

Nearly half the Duval file is Special Needs Plans, and that deserves a straight explanation

44 of Duval County’s 90 records for 2026 are Special Needs Plans, usually written as SNP and said out loud as “snip”. That is the highest SNP count of the four First Coast counties, and it is not an accident of the plan file. It reflects who lives here.

A Special Needs Plan is a type of Medicare Advantage plan that may only enrol people who meet a defined condition, with benefits and care management built around that condition. There are three kinds. A D-SNP is for people eligible for both Medicare and Medicaid, often called dual eligibles. A C-SNP is for people living with a specific severe or disabling chronic condition, such as diabetes, heart failure or end-stage renal disease. An I-SNP is for people who live in a nursing facility or who need that level of care at home.

The benefits on a SNP often look more generous than anything on the general shelf, because the plan is paid to manage a harder population. That is why the eligibility rule exists, and why you cannot choose one the way you choose a regular plan. If you do not meet the condition you cannot enrol, and a plan finder showing you one is showing what exists in the county rather than what you can buy. If you think you might qualify — particularly for a D-SNP, where the trigger is your Medicaid status rather than a diagnosis — ask your state Medicaid office, 1-800-MEDICARE, or Florida’s free counselling programme before you assume the answer is no.

Set the 44 SNP records aside and Duval’s general-enrollment shelf is 46 records deep. Filter those for your own doctors and prescriptions and, in our experience, most people are down to three or four real candidates before premium is mentioned once. Ninety plans is a marketing number. Four is a decision.

What Medicare costs in 2026 before any plan is involved

Underneath every private plan sit federal numbers that are identical in Riverside, Mandarin, the Northside and everywhere else in the country. Your county only decides which private plans you may layer on top. For the 2026 plan year the standard Part B premium is $202.90 a month, usually deducted from a Social Security payment, and the annual Part B deductible is $283. The Part A hospital deductible is $1,736 per benefit period — not per calendar year, which means a later admission can start a second one.

Then comes the sentence that explains the existence of the entire private plan industry. Original Medicare leaves you paying 20% of most Part B services with no annual cap. No ceiling, no maximum, no point at which it stops. A Medicare Advantage plan answers that with an out-of-pocket maximum. A Medicare Supplement answers it by paying most of the 20% on your behalf. We go through the rest in our post on what Medicare does not cover in 2026.

Why does a $0 premium tell you so little in Duval County?

Because 28 of the county’s 35 MA-PD plans charge one for 2026 — 80%. When four plans in five carry the same price, the price has stopped carrying information. The mean MA-PD premium across Duval is $15.96 a month and the highest-priced plan in the file is $184, a rounding error against the $202.90 you already owe for Part B.

The number that actually varies is the in-network maximum out-of-pocket, shortened on paperwork to MOOP: the ceiling on what you can pay in copays and coinsurance for covered in-network care in a calendar year. In Duval for 2026 the median is $6,750, the mean is $6,010, and the range runs from $2,500 to $9,250. That is a $6,750 gap between the safest and the most exposed plan, inside one county, at the same premium.

Put it in a household’s terms. Two retired neighbours on the same street in San Marco each pay $0 a month. If one holds the $2,500 plan and the other holds the $9,250 plan, the year that tests both of them costs one of them $6,750 more, and nothing on either postcard would have predicted it. The premium column sorts nothing here. The MOOP column sorts everything. If you’d rather just talk it through, call 888-627-0085 and ask for a plain-language answer.

The same logic is why the hospital behind a plan’s network is worth checking by name rather than by logo — the CMS Care Compare ratings across this metro run from one end of the scale to the other, and we deal with that properly in our post on hospital star ratings in Northeast Florida.

Duval is not its neighbours, and the plan file knows it

The 2023 American Community Survey puts Duval County’s population at 1,007,189 with a median age of 36.7 — the youngest of the five counties we serve, and 9.6 years younger than Nassau at 46.3. Median household income is $68,447, per capita income $38,827, the poverty rate 14.6%, unemployment 4.5%, and the median home value $274,900.

Now put the county next door beside it. St. Johns County’s median household income is $106,169, 55% above Duval’s, with a poverty rate of 6.7% and a median home value of $457,600. The county line between them is a twenty-minute drive. Same state, same Medicare program, same landscape file, very different households reading it.

This is where the SNP count stops being a statistic and becomes a description. A county with this income profile, this poverty rate and this many uninsured residents has a large dual-eligible population, and carriers file D-SNPs where dual eligibles live. Duval’s 44 Special Needs Plan records are the plan market answering the county the Census describes. For readers under 65 inside that 112,908, Medicare is not the answer yet and the Marketplace is — our Jacksonville ACA guide for 2026 covers that side.

What the county health data says about the year you should plan for

The CDC’s PLACES program models health measures down to county level. For Duval’s adult population of 1,030,822 in the 2023 release, obesity is estimated at 34.3%, diagnosed diabetes at 11.8% to 12.8% depending on whether you read the crude or the age-adjusted estimate, high blood pressure at 33.7% to 35.4%, high cholesterol among adults ever screened at 30.9% to 34.1%, and current cigarette smoking at 13.9%. Arthritis runs 23.4% to 25.2%, COPD 6.5% to 7.0%, and coronary heart disease 5.7% to 6.3%.

These are model-based estimates with confidence intervals attached, so read them as the shape of a county rather than a headcount. Roughly one adult in three carries high blood pressure, roughly one in eight has diagnosed diabetes, and 75.5% to 76.4% had a routine checkup in the past year, which means close to a quarter did not. Those are the conditions that decide whether a plan’s drug tiers and specialist copays matter to you, and several are the conditions a C-SNP is built around.

Plan for the year you might have, not the year you are having. A healthy 66-year-old choosing on premium is choosing for today; the MOOP column exists for the year the PLACES table says is statistically ordinary here.

The drug plan is a separate decision, and Florida’s shelf is short

If you choose Original Medicare, with or without a supplement, your drug coverage has to come from a stand-alone Part D plan, and Florida’s 2026 shelf is nothing like the Medicare Advantage shelf. There are ten plans statewide from five parent organizations, sold across the whole state rather than county by county, with monthly premiums from $0.00 to $217.00. Seven of the ten charge the full $615 maximum deductible, and none earned a Part D summary star rating of 4 or better for 2026.

The federal floor is the same whichever you pick: every 2026 Part D plan carries a $2,100 annual out-of-pocket cap on covered drugs, after which covered drugs cost you nothing for the rest of the year. What differs is everything before the cap — the deductible, the tier your drugs land on, which pharmacies count as preferred. We went through all ten in our review of Florida’s 2026 stand-alone Part D plans. Your drug list picks the plan; the premium does not.

The Florida rule that makes this decision hard to undo

Most people in Jacksonville pick Medicare Advantage. For someone with local doctors, a modest drug list and a plan chosen on its MOOP, it is a reasonable choice we recommend without embarrassment. What we always say out loud is what it costs in flexibility later, because that part is one-directional in this state.

Federal law gives you one 6-month Medigap open enrollment window, beginning the first day of the month in which you are both 65 or older and enrolled in Part B. Inside it a carrier must sell you a supplement regardless of your health. Outside it, Medicare.gov states plainly that there is no federal guarantee an insurance company will sell you a Medigap policy, and that if one does, past or present health problems can make it cost more.

We read the Florida Office of Insurance Regulation’s 2026 Medigap FAQ end to end and found no birthday-based right to switch carriers without underwriting. What Florida law does give you: every Medicare Supplement policy sold here is guaranteed renewable, a 30-day free look lets you return one for a full refund, and if you joined a Medicare Advantage plan when first eligible at 65 and leave within a year, the federal trial right lets you buy any Medigap policy on a guaranteed-issue basis. The full comparison sits in our Medicare Advantage versus supplement guide.

How to sort 90 plan records in one evening

You can do the core of this yourself in about ninety minutes the first year and thirty each autumn afterwards. Do the steps in order. Each one shortens the list for the next, which is the only way a 90-row file becomes a decision.

1. Write down every prescription with the exact doseGeneric name, strength, how often. Include the seasonal ones and the ones a specialist started. This list moves more money than every premium comparison combined.
2. List the doctors and hospital systems you refuse to losePrimary care, each specialist, the imaging centre, and the hospital system you would want a serious problem handled by. Mark which are genuinely negotiable.
3. Pull your Medicare number and your Part A and Part B start datesThey are printed on your red, white and blue card. The Part B date governs your one-time 6-month Medigap window, which in Florida decides whether you can change direction later.
4. Work out whether any Special Needs Plan applies to youIf you have both Medicare and Medicaid, a qualifying chronic condition, or you need nursing-facility-level care, a D-SNP, C-SNP or I-SNP may be open to you. If none applies, filter all 44 SNP records out and stop reading their benefit summaries.
5. Run your lists through the Plan Finder at Medicare.govEnter your ZIP code, your drugs and your pharmacy, and let the official tool estimate total annual cost rather than monthly premium. A Jacksonville ZIP returns what is actually sold at your address.
6. Write the in-network out-of-pocket maximum next to every finalistFor 2026 the Duval range is $2,500 to $9,250 against a $6,750 median. This column is your worst case, and it varies more than anything else on the page.
7. Call each finalist and confirm the network in writingName your doctor, the practice and the hospital system, and ask whether each is contracted for the coming plan year rather than the current one. Ask by email. Printed directories go stale within weeks.
8. Say early if you spend part of the year somewhere elseA local-network plan behaves very differently in another state. Raise it at the start, because it can rule out whole categories before the details matter.
9. Get a second opinion from someone with nothing to sellCall 1-800-MEDICARE, or Florida’s free counselling programme SHINE on 1-800-963-5337, run by the Florida Department of Elder Affairs. Both are free and neither is paid by a carrier.

Bring your current plan and your prescription list; we’ll do the comparison with you. Anyone who arrives with those two lists finished has already done the part that takes the longest.

Before and after: one Jacksonville household, on paper

Meet Ray and Denise, both 67, in Arlington. They are invented, and the table below applies published 2026 Duval County figures to their invented situation. No carrier is named and no premium is quoted, so read it as arithmetic rather than an offer.

In the before column they did what the mail suggested: took the first $0-premium plan a caller offered, never looked at the out-of-pocket maximum, and spent two weeks reading the benefit summary of a Special Needs Plan they were never eligible to join. In the after column they worked the nine steps, ruled the SNP records out in five minutes, and chose from the low end of the county MOOP range with both doctors confirmed in writing.

Notice what the after column did not require. Not more premium, and not any knowledge an ordinary person cannot look up. It required sorting on different columns and eliminating early. That is the entire method.

When are you actually allowed to change any of this?

If you are new to Medicare, your Initial Enrollment Period runs seven months, starting three months before the month you turn 65 and ending three months after it. If you are already enrolled, the Annual Enrollment Period runs 15 October to 7 December each year, with the new plan starting 1 January and the request due by 7 December. And if you are already in a Medicare Advantage plan, a second window from 1 January to 31 March lets you switch once or drop back to Original Medicare.

Those are real regulatory deadlines, not urgency invented by a caller — a distinction that matters in a market this size, where something is said to expire almost every week between Labor Day and Christmas. Our guide to the 2026 enrollment periods maps every window. If you are comparing counties because you are moving or splitting your time, the same 2026 files sit behind our Clay County, St. Johns County and Nassau County reviews.

Where to get help that has nothing to sell you

Keep an unbiased source in your pocket, particularly in a county where twelve companies compete for your attention. Medicare.gov is the official government site, and its Plan Finder runs on the same landscape data every agent uses. 1-800-MEDICARE is staffed around the clock. Florida’s State Health Insurance Assistance Program is SHINE, on 1-800-963-5337, run by the Florida Department of Elder Affairs through local Area Agencies on Aging; its counsellors are trained volunteers and no carrier pays them.

McDowell Business Resources is an independent agency, not an insurance carrier, and we are not affiliated with or endorsed by the U.S. government, the federal Medicare program or CMS. We do not offer every plan available in your area, and what we can tell you is limited to the plans we do offer. The numbers above plus the Plan Finder will get you most of the way there without us in the room.

How we help in Duval County

What we add is the labour and the second pair of eyes. We run your exact doctors, your exact drug list and your preferred hospital system against every plan we represent at your address, and we show you the total expected cost in a healthy year and in a heavy-care year rather than the monthly premium. Where a Special Needs Plan might genuinely apply we say so and tell you what to check and with whom; where it plainly does not, we take those 44 records off your table.

Then we do it again every autumn, because networks and formularies reset on 1 January whether or not anybody warns you. The county detail lives on our Duval County page, the service outline on our Medicare page, and the statewide picture in our Florida Medicare guide for 2026. There’s no cost and no pressure — book a free consultation and we’ll walk through it together.

What you get out of doing this properly

You stop comparing plans on the number 80% of them share and start comparing on the numbers that differ by thousands. You know your worst case before the year that produces it, and you know which of the ninety records were never available to you and which four were. In the county with the most choice and the widest spread on the First Coast, volume stops being a problem and becomes what it is: a longer list to filter, with better odds at the end of it than a six-carrier county can offer.

The review takes one evening a year. Whatever you decide, decide it on the numbers. If you want help getting to them, we’re here.
