If you are 65 or older and enrolled in Medicare in Florida, you have almost certainly been asked to choose between traditional Medicare and Medicare Advantage. For retirees in Sun City Center, Lakewood Ranch, Bradenton, and communities throughout District 16, this is one of the most consequential healthcare decisions you will make. And it is a decision that Congress is actively debating in ways that could affect your coverage, your costs, and your access to the doctors you trust.
This guide explains the real differences between Medicare Advantage and traditional Medicare, what Congress is currently debating, and what John Peters will fight for to protect Florida seniors.
What Is Medicare Advantage?
Medicare Advantage — officially called Medicare Part C — is an alternative way to receive your Medicare benefits. Instead of the federal government paying your medical bills directly (as in traditional Medicare), the government pays a private insurance company a set amount each month to cover your care. That private insurer then manages your benefits, builds a provider network, and handles your claims.
Medicare Advantage plans typically bundle together hospital coverage (Part A), medical coverage (Part B), and prescription drug coverage (Part D) into a single plan. Many plans also include extra benefits that traditional Medicare does not cover — such as dental, vision, hearing, and fitness memberships — which is a major reason they have become so popular, particularly in Florida.
As of 2025, more than half of all Medicare beneficiaries nationwide are enrolled in Medicare Advantage plans. In Florida, the enrollment rate is even higher. That popularity makes any congressional action on Medicare Advantage funding a direct concern for millions of Florida seniors.
Medicare Advantage vs. Traditional Medicare: Side-by-Side Comparison
The choice between Medicare Advantage and traditional Medicare involves real trade-offs. Neither option is universally better — the right choice depends on your health needs, your doctors, your budget, and how much you travel. Here is how they compare on the factors that matter most:
| Feature | Traditional Medicare | Medicare Advantage |
|---|---|---|
| Provider network | Any doctor or hospital that accepts Medicare nationwide | Must use plan’s network (HMO/PPO); out-of-network care may cost more or not be covered |
| Monthly premium | Part B premium (~$185/mo in 2025) + optional Medigap supplement | Often $0 extra premium beyond Part B, but varies by plan and area |
| Out-of-pocket maximum | No cap — unlimited exposure without Medigap supplement | Capped by law ($8,850 in-network max in 2025) |
| Drug coverage | Requires separate Part D plan | Usually included in the plan |
| Dental, vision, hearing | Not covered (except limited situations) | Often included as extra benefits |
| Prior authorization | Generally not required | Often required for specialist visits, procedures, and hospital stays |
| Travel coverage | Accepted anywhere in the U.S. by any Medicare provider | Emergency care covered nationwide; routine care often limited to plan area |
| Plan changes | Benefits stable year to year | Plans can change networks, premiums, and benefits annually |
| Referrals needed | No referrals required | HMO plans usually require referrals; PPO plans typically do not |
The bottom line: traditional Medicare offers maximum flexibility and nationwide access, but without a Medigap supplement, your out-of-pocket exposure is unlimited. Medicare Advantage typically costs less upfront and includes extra benefits, but restricts you to a network and introduces prior authorization requirements that can delay or complicate care.
How Does Medicare Advantage Work in Florida?
Florida has one of the highest Medicare Advantage enrollment rates in the nation. More than 55% of Florida’s Medicare beneficiaries are enrolled in Advantage plans — well above the national average. That high enrollment rate reflects Florida’s demographics: the state has a large, concentrated retiree population, and insurers have competed aggressively for that market with generous benefits packages.
Major Medicare Advantage plans operating in Florida include UnitedHealthcare, Humana, Aetna, Devoted Health, and Florida Blue. In Manatee and Hillsborough counties, most zip codes have multiple competing plans available during open enrollment, giving Florida seniors more choices than residents of many other states.
Florida Medicare open enrollment runs October 15 through December 7 each year, with coverage beginning January 1. Outside of open enrollment, you can only switch plans under specific circumstances (moving, losing coverage, etc.). If you are approaching 65, your initial enrollment window begins three months before your birthday month and ends three months after.
One Florida-specific consideration: many retirees who split time between Florida and a northern state find that Medicare Advantage’s network restrictions create problems when they travel. Traditional Medicare with a Medigap supplement provides seamless coverage in both states; Medicare Advantage HMO plans typically do not.
What Is Medicare Prior Authorization and Why Does It Matter?
Prior authorization is a requirement by Medicare Advantage plans that your doctor obtain the insurer’s approval before providing certain services — specialist visits, diagnostic imaging, surgeries, hospital admissions, and some medications. In theory, prior authorization is a cost-control tool. In practice, it has become one of the most significant complaints about Medicare Advantage plans.
A 2022 report by the Department of Health and Human Services Office of Inspector General found that Medicare Advantage plans denied 13% of prior authorization requests for services that would have been covered under traditional Medicare. Many of those denials were later overturned on appeal — but the appeals process takes time, and for a patient waiting for a surgery or cancer treatment, that delay has real consequences.
Congress has debated prior authorization reform for several years. The Improving Seniors’ Timely Access to Care Act — which would have required Medicare Advantage plans to respond to prior authorization requests within specific timeframes and to make the process more transparent — passed the House with strong bipartisan support but stalled in the Senate. John Peters supports this reform and will push for its passage.
What Medicare Changes Mean for Sun City Center and District 16 Retirees
Sun City Center — located in southern Hillsborough County within Florida’s 16th Congressional District — is one of the largest retirement communities in the United States, with over 30,000 residents. Combined with the substantial retiree populations in Lakewood Ranch, Bradenton’s waterfront communities, and the active adult developments throughout northern Manatee County, District 16 has one of the highest concentrations of Medicare beneficiaries of any congressional district in Florida.
That means federal Medicare policy is not an abstract Washington debate for this district — it is a direct financial and healthcare reality for a substantial portion of FL-16’s population.
Congress is currently debating significant changes to how the federal government pays Medicare Advantage plans — the rates insurers receive for each enrollee. Some proposals in the federal budget reconciliation process would reduce these payments. The consequence, as insurers themselves have warned, would be plan exits from certain markets, benefit reductions, and premium increases for existing enrollees.
For Sun City Center and Lakewood Ranch retirees enrolled in Medicare Advantage, the practical risk is real: your plan could reduce its dental and vision benefits, narrow its provider network, or — in the worst case — exit the Florida market entirely, forcing you to find new coverage mid- retirement. For retirees on fixed incomes, those disruptions are not minor inconveniences. They are serious financial and health risks.
John Peters’ Commitment to Protecting Medicare for Florida Seniors
John Peters will not support funding cuts that cause Medicare Advantage plans to reduce benefits, raise premiums, or exit Florida markets. The federal government made a commitment to Florida’s seniors through Medicare, and that commitment must be honored — not eroded through budget maneuvers that treat retirees’ healthcare as a line item to be optimized.
Specifically, Peters will fight for:
- No cuts to Medicare Advantage payment rates that would trigger benefit reductions or plan exits in Florida markets.
- Prior authorization reform. The Improving Seniors’ Timely Access to Care Act must pass. Medicare Advantage plans should not be able to deny or delay care that traditional Medicare would cover without meaningful accountability and appeal rights.
- Transparency in plan changes. Seniors deserve adequate notice and clear information when Medicare Advantage plans change their networks, benefits, or premiums — so they can make informed decisions during open enrollment.
- Protecting traditional Medicare. For those who choose traditional Medicare, Peters opposes any structural changes that would convert it to a premium-support or voucher model. Original Medicare must remain a guaranteed benefit, not a voucher.
Healthcare for seniors is not a line item. It is a promise that must be kept. See John Peters’ full platform for District 16 →
Frequently Asked Questions
What is the difference between Medicare Advantage and traditional Medicare?
Traditional Medicare (Parts A and B) is administered directly by the federal government and lets you see any doctor nationwide who accepts Medicare. Medicare Advantage (Part C) delivers the same benefits through a private insurer that uses a provider network and may require prior authorization. Advantage plans often include extra benefits like dental and vision that traditional Medicare doesn’t cover, but restrict you to their network and can change their benefits annually.
Why are some Medicare Advantage plans considered bad?
The most common complaints about Medicare Advantage plans involve prior authorization denials that delay or block needed care, narrow provider networks that limit access to specialists, and plan changes during annual enrollment that reduce benefits without adequate notice. A 2022 HHS Inspector General report found that MA plans denied 13% of prior authorization requests for services traditional Medicare would have covered — with many denials later overturned on appeal.
Does Medicare Advantage cover dental and vision?
Most Medicare Advantage plans include some dental, vision, and hearing benefits — which traditional Medicare does not cover. However, the scope of these benefits varies significantly by plan. Some plans offer comprehensive dental coverage; others provide only basic preventive care. Always review the specific benefits summary of any plan before enrolling during open enrollment (October 15 – December 7).
How does Medicare Advantage work in Florida?
More than 55% of Florida’s Medicare beneficiaries are enrolled in Medicare Advantage plans — one of the highest rates in the nation. Major plans in Manatee and Hillsborough counties include UnitedHealthcare, Humana, Aetna, Devoted Health, and Florida Blue. Florida’s open enrollment runs October 15 – December 7. Floridians who split time between Florida and another state should pay particular attention to network restrictions, which can affect coverage when traveling.
What is prior authorization in Medicare Advantage?
Prior authorization requires your doctor to get approval from your Medicare Advantage insurer before providing certain services — specialist referrals, surgeries, imaging, hospital admissions, and some medications. While intended as a cost-control measure, prior authorization can delay or deny needed care. Congress has been debating the Improving Seniors’ Timely Access to Care Act to reform prior authorization practices and require faster, more transparent decisions from Medicare Advantage plans.
Florida’s seniors deserve a representative who will protect their Medicare — not use it as a budget bargaining chip. Join John Peters’ campaign and help send a fighter to Congress for District 16.
