Understanding Medicare Part C can be confusing for many adults turning 65 or becoming newly eligible for Medicare. In fact, studies show that 65% of seniors on Medicare are unfamiliar with Medicare Advantage plans, also known as Medicare Part C [Medicare Advantage awareness study].

Early misunderstandings about Medicare Part C can impact your coverage choices, costs, and provider access for years to come in Tampa and beyond.

Quick Answer: Medicare Part C, or Medicare Advantage, is a private insurance alternative to Original Medicare that includes hospital (Part A) and medical (Part B) coverage, and often Part D prescription drug benefits. Coverage details and provider networks vary by plan and location.

What Is Medicare Part C? The Basics Explained

Medicare Part C is more commonly known as Medicare Advantage. These plans are offered by private insurance companies approved by Medicare to provide coverage that combines hospital, medical, and often prescription drug benefits into a single plan.

Unlike Original Medicare, which is government-run, Medicare Part C plans provide a bundled approach to healthcare coverage.

Medicare Part C plans come in various types including Health Maintenance Organization (HMO), Preferred Provider Organization (PPO), and others, each with different rules about how you access care. Importantly, Medicare Advantage plans must cover everything that Original Medicare covers with hospital (Part A) and medical (Part B) services, but many also offer additional benefits.

In Tampa, major healthcare providers and hospital systems such as Tampa General Hospital, BayCare Health System, AdventHealth Tampa, and HCA Florida South Tampa Hospital are commonly included in local Medicare Advantage plan networks.

Local clinics like Tampa Family Health Centers and USF Health are also frequently partnered with Medicare Advantage plans, giving Tampa residents a wide range of in-network options.

Additionally, Florida-specific Medicare entities such as the Florida Department of Elder Affairs, SHINE (Serving Health Insurance Needs of Elders), Florida Blue (Blue Cross and Blue Shield of Florida), and the Florida Office of Insurance Regulation play key roles in the administration and regulation of Medicare Advantage plans throughout the state.

• Medicare Part C = Medicare Advantage, offered by private insurers
• Combines hospital, medical, and often prescription drug coverage
• May include extra benefits like dental, vision, and wellness
• Provider networks and coverage options vary by plan and location
• Florida entities like SHINE and Florida Blue provide local support and plan options

How Medicare Part C Differs From Original Medicare

• Network Restrictions: Many Medicare Part C plans require you to use a network of providers, which may limit where you can get care compared to Original Medicare’s nationwide acceptance. In Tampa, check if your preferred providers, such as Moffitt Cancer Center or St. Joseph’s Hospital, are included in your plan’s network.
• Additional Benefits: Medicare Advantage plans often include extras like dental, vision, hearing, and wellness programs that Original Medicare does not provide.
• Cost Structure: These plans may have different copays, coinsurance, and out-of-pocket maximums, offering some financial protection that Original Medicare lacks.

• Part C plans may limit provider choice but offer extra benefits
• Out-of-pocket maximums protect against high costs
• Prescription drug coverage often included in Part C
• Florida residents can access plans regulated by the Florida Office of Insurance Regulation

Medicare Part C vs. Parts A, B, and D: Coverage Comparison

Medicare coverage is divided into several parts, each covering different aspects of healthcare. Understanding how Medicare Part C compares to Original Medicare Parts A, B, and D can clarify your coverage choices.

Part C includes all benefits covered by Part A (hospital care) and Part B (medical services), often with enhancements such as lower copays and out-of-pocket limits. Most Medicare Advantage plans also include Part D prescription drug coverage, which must be purchased separately under Original Medicare.

Choosing Part C means you are typically selecting a managed care plan with network restrictions, contrasting with the broader provider access of Original Medicare. However, Part C plans may offer additional benefits beyond what Parts A, B, and D cover individually.

In Florida, entities such as the Florida Office of Insurance Regulation and Florida Blue help ensure plan quality and consumer protection.

• Part C bundles hospital, medical, and often drug coverage
• Usually includes extras like dental or vision
• Has an annual out-of-pocket maximum, unlike Original Medicare

Medicare Part C Costs and Financial Considerations

The cost of Medicare Part C plans can vary widely in Tampa, with monthly premiums ranging from $0 to over $200 in 2026. While some plans charge no additional premium beyond the mandatory Medicare Part B premium, others may have higher fees depending on coverage and benefits.

One of the advantages of Medicare Advantage plans is the annual out-of-pocket maximum, which limits your total spending for covered services. Copays and coinsurance amounts vary by plan and service type, so it’s important to review plan details carefully.

Remember, you must continue paying your Medicare Part B premium even if you enroll in a Medicare Part C plan. Prescription drug costs are usually included within the plan’s structure if Part D coverage is offered.

Florida has a robust Medicare Advantage market, with more than 60 plans available in many counties, including Hillsborough County (Tampa) as of 2026.

Types of Medicare Part C Plans Available

Medicare Part C plans come in different types to suit various healthcare needs. The most common are Health Maintenance Organization (HMO) plans, which require you to select a primary care physician and get referrals for specialists.

Preferred Provider Organization (PPO) plans offer more flexibility, allowing you to see providers both in and out of network, though costs are lower when staying in-network. Special Needs Plans (SNPs) are designed for people with specific health conditions or circumstances, such as chronic diseases.

Regional PPO plans cover larger geographic areas, sometimes spanning multiple states, providing broader access than local plans.

In Tampa, leading Medicare Advantage providers include Humana, UnitedHealthcare, Aetna, Florida Blue (Blue Cross and Blue Shield of Florida), and Cigna. Many of these insurers have partnerships with major Tampa healthcare systems, such as BayCare and AdventHealth, ensuring access to local hospitals and specialists.

Frequently Asked Questions About Medicare Part C

Can I switch from Medicare Part C back to Original Medicare?

Yes. You can switch during the Annual Open Enrollment (October 15 – December 7) or the Medicare Advantage Open Enrollment Period (January 1 – March 31). If you switch back, you may need to enroll separately in a Part D prescription drug plan, and enrolling in Medigap (Medicare Supplement) coverage could be limited depending on your timing. [Source: Medicare.gov]

Does Medicare Part C cover prescription drugs?

Most Medicare Advantage plans include prescription drug coverage (Part D). However, some plans require separate Part D enrollment. Coverage and formularies vary by plan, so it is important to verify which medications are covered under each plan.

Can I see any doctor with Medicare Part C?

Typically, you must use the plan’s provider network. PPO plans generally offer more flexibility to see out-of-network providers at a higher cost, while HMO plans restrict you to network providers and often require referrals for specialists. In Tampa, check if your preferred specialists at facilities like Moffitt Cancer Center or USF Health are included in your plan’s network.

What happens to my Medicare Part C if I move?

If you move outside your plan’s service area, you must choose a new Medicare Advantage plan available in your new location. This change qualifies you for a Special Enrollment Period. It’s important to research plan options in your new area before moving. [Source: Medicare.gov]
