Medicare Advantage known as Medicare Part C — is offered by private insurance companies that have been approved by the federal government to deliver your Medicare benefits. According to Medicare.gov, every Medicare Advantage plan must cover everything Original Medicare covers, and most include additional benefits that Original Medicare does not — dental, vision, hearing, and prescription drug coverage being the most common.
When you enroll in a Medicare Advantage plan, you do not leave Medicare. You still have Medicare. You are choosing to receive your Medicare benefits through a private company instead of directly through the federal government. The federal government pays that company a fixed monthly amount to cover your care, which is why most plans can afford to offer $0 or very low monthly premiums.
According to KFF.org, more than half of all Medicare beneficiaries in the United States are enrolled in a Medicare Advantage plan in 2026. HMOs account for 61% of enrollees and PPOs account for 38%. The growth has been steady every year since 2010, driven largely by the combination of $0 premiums and extra benefits that Original Medicare does not offer.
The most important thing to understand before you compare any plans is this: the $0 premium is real, but it is only one part of your total cost. The other parts — copays, coinsurance, prior authorization requirements, and your maximum out-of-pocket — are where the real differences between plans appear.
When You Can Enroll
Your Initial Enrollment Period is a seven-month window surrounding your 65th birthday — three months before, your birthday month, and three months after. If you miss that window without qualifying employer coverage, you could face permanent penalties on your Part B premium. You can also join or switch plans every year during the Annual Enrollment Period from October 15 through December 7, with changes taking effect January 1. A separate Open Enrollment Period runs January 1 through March 31, during which anyone already enrolled in Medicare Advantage can switch plans or return to Original Medicare.

The 2026 Numbers: What’s Actually Available in St. Lucie County
According to Medicare.org, St. Lucie County has 44 Medicare Advantage plans in 2026. Of those, 39 carry a $0 monthly premium. Approximately 38,149 beneficiaries in St. Lucie County are currently enrolled in Medicare Advantage, and 70% of available plans hold a 4-star rating or higher from CMS.
According to MedicareAdvantage.com, the average monthly premium across all plans in the county is $26.29, with an average CMS star rating of 3.63 out of 5. Plans rated below 3 stars have consistently performed poorly on quality metrics — member satisfaction, access to care, and management of chronic conditions. Star ratings matter and should be part of every plan comparison.
The carriers most active in Port St. Lucie and St. Lucie County in 2026 include Humana, Aetna, United Healthcare, Devoted Health, and Florida Blue Medicare. Each offers multiple plan designs at different premium and cost-sharing levels, and each maintains its own provider network. The same doctor can be in-network with one carrier and completely out-of-network with another offering a plan at the same premium in the same county.
The only accurate way to see what is available to you is to enter your specific zip code at the Medicare Plan Finder at Medicare.gov. Plan availability, benefits, and networks change every year — always verify current information rather than relying on what applied in a previous plan year.
HMO vs PPO: The Choice That Matters Most
Before you look at premiums or star ratings, you need to understand the structural difference between HMO and PPO plans. This single choice determines whether your current doctors are covered, how much freedom you have to seek care, and what happens if you need treatment outside your local area.
HMO Plans — Health Maintenance Organization
According to Medicare.gov, HMO plans require you to choose a primary care physician who coordinates your care and provides referrals to specialists. You must use doctors and hospitals within the plan’s network — with the exception of genuine emergencies. If you see a provider outside the network without prior authorization, you will generally pay the full cost yourself.
HMO plans typically offer the lowest premiums in the Port St. Lucie market. According to KFF.org, HMO plans nationally average $12 per month in supplemental premiums in 2026 and carry an average in-network out-of-pocket maximum of $4,636. The trade-off is tight network restrictions. For Port St. Lucie residents who travel frequently, spend time in another state, or have established relationships with specialists they are not willing to leave, HMO plans carry real limitations that a $0 premium does not offset.
PPO Plans — Preferred Provider Organization
According to Medicare.gov, PPO plans allow you to see any doctor who accepts Medicare — you pay less when you stay within the plan’s preferred network, and more when you go outside it. PPOs do not require referrals to see specialists, which simplifies care significantly for anyone managing multiple health conditions or seeing multiple doctors regularly.
According to KFF.org, the average out-of-pocket maximum for PPO plans is $6,592 in 2026 — higher than HMOs, but with significantly more provider flexibility. For people who see specialists regularly, travel between states, or want more flexibility outside a narrow network, PPOs often represent better long-term value.
The Network Verification Step Most People Skip
Before selecting any Medicare Advantage plan — HMO or PPO — call your most important doctors directly and ask whether they are currently accepting patients under that specific plan. Do not rely on the carrier’s online directory. Provider directories are updated infrequently and are often inaccurate. A five-minute phone call to your doctor’s billing office before you enroll can save months of problems after.
You can compare all Medicare Advantage plan types — HMO, PPO, PFFS, and SNP — side by side at Medicare.gov.
What Medicare Advantage Actually Covers in 2026
Every Medicare Advantage plan must cover everything Original Medicare covers — all Part A hospital services and all Part B medical services. According to Medicare.gov, this baseline includes inpatient hospital care, outpatient visits, preventive services, durable medical equipment, and emergency care anywhere in the United States regardless of network.
Most plans in Port St. Lucie in 2026 also include:
Prescription Drug Coverage (Part D): Most plans bundle drug coverage. According to Medicare.gov, no Part D deductible may exceed $615 in 2026. If your plan includes drug coverage you do not need a separate Part D plan. If you qualify for help paying for drug costs, read our guide on Extra Help with Medicare Part D — millions of Port St. Lucie residents qualify and never apply.
Dental: Many plans include routine cleanings, x-rays, and sometimes basic restorative work. Coverage varies significantly — some plans cap annual dental benefits at $500 while others offer $2,000 or more.
Vision: Most plans include an annual eye exam and an allowance for glasses or contacts, typically ranging from $100 to $300 per year.
Hearing: Many plans include an annual hearing exam and a hearing aid benefit — one of the most valuable extras given that Original Medicare covers virtually no hearing-related costs.
Fitness: Most major carriers in St. Lucie County include SilverSneakers or a comparable fitness benefit.
Transportation and OTC: Some plans include rides to medical appointments and a quarterly allowance for over-the-counter items.
Pro Tip: Do not let extra benefits drive your decision. A plan that includes $500 in dental benefits but charges $50 per specialist visit could cost you far more than the dental benefit is worth if you see specialists regularly. Always calculate your estimated total annual cost — premium plus expected copays based on your actual usage.
The Real Cost Behind the $0 Premium
The $0 premium is accurate for 39 of the 44 plans in St. Lucie County in 2026. But your Part B premium of $202.90 per month — confirmed by CMS.gov — continues regardless of which plan you choose. That premium does not disappear with Medicare Advantage.
Beyond the Part B premium, you will pay copays and coinsurance as you use healthcare throughout the year. Typical cost-sharing in the Port St. Lucie market for 2026:
- Primary care visits: $0 to $20 per visit
- Specialist visits: $20 to $50 per visit
- Inpatient hospital stays: $250 to $350 per day for the first several days
- Emergency room visits: $65 to $120 per visit (waived if admitted)
- Urgent care visits: $40 to $65 per visit
The Annual Out-of-Pocket Maximum
Once you hit your plan’s annual maximum, the plan pays 100% of covered in-network services for the rest of the calendar year. According to KFF.org, the average in-network out-of-pocket maximum in St. Lucie County is $5,922, with a federal cap of $9,250. Original Medicare has no out-of-pocket maximum — a serious hospitalization without a supplement could result in unlimited personal costs.

The Part B Give Back
Some Medicare Advantage plans offer a Part B Premium Reduction benefit that returns a portion of your $202.90 monthly Part B premium. Not all plans offer this and the amount varies. Check the specific plan’s Summary of Benefits for the exact reduction amount before enrolling.
Medicare Advantage vs Original Medicare: An Honest Comparison
The choice between Medicare Advantage and Original Medicare is one of the most consequential decisions you will make at 65. There is no universally correct answer — it depends entirely on your health, your doctors, your budget, and how you prefer to receive care.
Original Medicare lets you see any doctor or hospital in the country that accepts Medicare — no referrals, no network restrictions. According to Medicare.gov, approximately 93% of physicians in the United States accept Medicare. The limitation is cost: without a supplement, your out-of-pocket exposure has no ceiling.
Medicare Advantage caps your annual out-of-pocket costs and adds extra benefits Original Medicare cannot match. The limitations are network restrictions, prior authorization requirements, and the reality that networks change at the start of each plan year.
Medicare Advantage tends to work best for people who are generally healthy, have all their preferred doctors confirmed in the plan’s network, want dental and vision bundled in, and live and receive care primarily in one geographic area.
It tends to work less well for people with complex or chronic conditions requiring frequent specialist visits or hospitalizations, people with strong attachments to specific physicians who may not be in-network, and people who travel frequently or spend significant time in another state.
If you are considering returning to Original Medicare after a period on Medicare Advantage in Florida, be aware that Florida allows medical underwriting for Medigap plans outside of your initial enrollment period. According to Medicare.gov, your ability to get a Medigap plan — and at what price — may depend on your current health history at the time you apply.
What Prior Authorization Really Means for Port St. Lucie Residents
Prior authorization means the insurance company must approve certain medical services before you receive them. According to KFF.org, prior authorization is standard across most Medicare Advantage plans in 2026 and applies to a wide range of services — including specialist referrals, certain imaging studies, inpatient admissions, outpatient procedures, and durable medical equipment.
Original Medicare does not require prior authorization for covered services. For a generally healthy person with routine healthcare needs, prior authorization rarely causes a problem. For someone managing a serious or complex health condition, it is a meaningful operational difference. Always check the specific plan’s prior authorization requirements in its Evidence of Coverage document before you enroll.
The Annual Enrollment Period: Your Window to Make Changes
The Annual Enrollment Period runs from October 15 through December 7 every year. During this window, any Medicare beneficiary can switch Medicare Advantage plans, drop Medicare Advantage and return to Original Medicare, switch Part D drug plans, or enroll in a plan for the first time. Changes take effect January 1.
Plans change their networks, copays, drug formularies, and extra benefits every single year. Reviewing your plan during every Annual Enrollment Period — not just the year you first enroll — is one of the most valuable habits you can build as a Medicare beneficiary.
There is also a Medicare Advantage Open Enrollment Period from January 1 through March 31. During this window, anyone already enrolled in Medicare Advantage can switch to a different plan or return to Original Medicare.
