What Is Medicare Advantage? How It Works and What to Consider in 2026

If you have Medicare — or you are about to get it — you have probably heard the term Medicare Advantage more than once. Maybe a friend switched to one. Maybe you have seen commercials for them. Or maybe someone mentioned it and you are not entirely sure what it means.

That is completely normal. Medicare Advantage is one of the most important options in Medicare, and it is worth understanding clearly — especially as the Medicare Annual Enrollment Period (AEP) opens on October 15.

This article explains what Medicare Advantage is, how it works, and what to think about when deciding if it might be right for you.

Medicare Advantage in Plain English

Medicare Advantage — also called Medicare Part C — is an alternative way to receive your Medicare coverage. Instead of getting your benefits directly from the federal government through Original Medicare (Parts A and B), you receive your Medicare benefits through a private insurance company that has been approved by Medicare.

Think of it this way: Original Medicare is the government's standard coverage. Medicare Advantage is a private plan that takes the place of that standard coverage. You are still in Medicare — you are just getting your benefits through a plan rather than directly through the government.

Medicare Advantage plans are required by law to cover at least everything that Original Medicare Parts A and B cover, which includes hospital stays, doctor visits, lab work, preventive care, and many other services.

What Does Medicare Advantage Typically Include?

Most Medicare Advantage plans go beyond the basics of Original Medicare. Many offer additional benefits that are not available through Original Medicare alone, such as:

• Prescription drug coverage — Many Medicare Advantage plans include Part D drug coverage, so you do not need a separate drug plan.
• Routine dental care — Cleanings, X-rays, and sometimes more comprehensive dental services.
• Vision coverage — Routine eye exams and help with the cost of glasses or contacts.
• Hearing benefits — Hearing exams and sometimes help with hearing aids.
• Fitness programs — Some plans include gym memberships or fitness benefits.
• Telehealth services — Virtual visits with healthcare providers.

In 2026, nearly all Medicare Advantage plans — 98% or more — offer some vision, dental, and hearing benefits, though the scope of those benefits varies from plan to plan.

These extra benefits are one of the main reasons Medicare Advantage is appealing to many people. Original Medicare generally does not cover routine dental, vision, or hearing care on its own.

How Does Medicare Advantage Work Differently from Original Medicare?

There are two key differences most people notice right away: provider networks and how you access care.

Provider Networks

Most Medicare Advantage plans require you to use a network of doctors, hospitals, and other providers. Whether you can see providers outside that network — and what it costs if you do — depends on the type of plan.

The two most common plan types are:

• HMO (Health Maintenance Organization) — You generally must see providers who are in the plan's network. You may need a referral from your primary care doctor to see a specialist. HMO plans often have lower out-of-pocket costs for in-network care. In 2026, more than 6 in 10 Medicare Advantage enrollees are in HMO plans.
• PPO (Preferred Provider Organization) — You have more flexibility to see providers outside the network, though you usually pay more for out-of-network care. PPOs tend to offer more freedom of choice but may have higher premiums or cost-sharing.

Because networks vary by location, the plans available to you — and the providers included — depend entirely on where you live.

Prior Authorization

Medicare Advantage plans sometimes require prior authorization — meaning the plan must approve certain services before they are covered. This is one of the trade-offs that can come with Medicare Advantage plans. It is worth asking about prior authorization requirements when reviewing any plan.

What Does Medicare Advantage Cost in 2026?

This is where Medicare Advantage often surprises people — sometimes in a good way.

You Still Pay the Part B Premium

Even if you enroll in a Medicare Advantage plan, you must continue to pay your Medicare Part B premium. In 2026, the standard Part B premium is $202.90 per month. This is in addition to any premium charged by your Medicare Advantage plan.

The Plan Premium Can Be Low — or Even $0

On top of the Part B premium, some Medicare Advantage plans charge an additional monthly premium for the plan itself. In 2026, the average monthly Medicare Advantage plan premium across all enrollees is $14.00 — and many plans have no additional premium at all.

In fact, about 75% of Medicare Advantage enrollees pay no additional plan premium beyond their standard Part B premium. The plan's cost to you depends on the specific plan and where you live.

Out-of-Pocket Maximums

One feature that often stands out about Medicare Advantage is the out-of-pocket maximum — a cap on how much you will spend on covered services in a year. Original Medicare has no out-of-pocket maximum, which means costs could pile up without limit if you have a serious illness or injury.

Medicare Advantage plans are required to cap your costs. In 2026, the federal maximum out-of-pocket limit for in-network services is $9,250. Many plans set their limits lower than this maximum. Once you reach your plan's limit, the plan covers 100% of covered in-network services for the rest of the year.

For people who want more predictable protection against high medical costs, the out-of-pocket maximum is a meaningful distinction.

Who Is Eligible for Medicare Advantage?

To join a Medicare Advantage plan, you must:

• Be enrolled in both Medicare Part A and Part B
• Live in the service area of the plan you want to join
• Be a U.S. citizen or lawfully present in the United States
• Not have End-Stage Renal Disease (ESRD) in most cases (though rules have changed and some plans now accept people with ESRD)

When Can You Enroll in a Medicare Advantage Plan?

There are specific periods when you can join, switch, or drop a Medicare Advantage plan:

Annual Enrollment Period (AEP)

The Annual Enrollment Period runs October 15 through December 7 each year. During AEP, anyone with Medicare can:

• Switch from Original Medicare to a Medicare Advantage plan
• Switch from one Medicare Advantage plan to another
• Switch from Medicare Advantage back to Original Medicare
• Join, switch, or drop a Part D prescription drug plan

Changes made during AEP take effect January 1 of the following year.

Medicare Advantage Open Enrollment Period (OEP)

If you are already in a Medicare Advantage plan, you have another opportunity to make changes during the Medicare Advantage Open Enrollment Period, which runs January 1 through March 31 each year. During this period, you can switch to a different Medicare Advantage plan or return to Original Medicare.

Initial Coverage Election Period

When you first become eligible for Medicare — typically around age 65 — you have a window to enroll in a Medicare Advantage plan during your Initial Enrollment Period.

What to Think About Before Choosing a Medicare Advantage Plan

Medicare Advantage is not the right fit for everyone, and no single plan is right for every person. Here are some of the most important things to consider:

• Your doctors and specialists — Are your current providers in the plan's network? This is often the most critical question.
• Your prescription medications — Does the plan cover your drugs? At what cost? Check the plan's formulary (drug list) carefully.
• Your hospitals — Are the hospitals you would use in-network?
• The plan's total costs — Look beyond the monthly premium. Review deductibles, copays, coinsurance, and the out-of-pocket maximum.
• Supplemental benefits — Are the extra benefits (dental, vision, hearing) meaningful to you, and what do they actually cover?
• Prior authorization requirements — How does the plan handle approvals for specialist visits or procedures?
• Star ratings — Medicare rates plans on a 1 to 5 star scale based on quality and performance. Higher-rated plans generally indicate better service and outcomes.

Medicare Advantage and Special Needs Plans

For certain individuals, a Special Needs Plan (SNP) may be worth exploring. SNPs are a type of Medicare Advantage plan designed for people with specific circumstances:

• Dual Special Needs Plans (D-SNPs) — For people who qualify for both Medicare and Medicaid
• Chronic Condition SNPs (C-SNPs) — For people with certain serious or chronic health conditions
• Institutional SNPs (I-SNPs) — For people who live in a nursing facility or require a similar level of care

SNPs are designed to coordinate care and benefits specifically around the needs of these groups. If you think you may qualify for a Special Needs Plan, it is worth asking about.

Medicare Advantage Is Not the Only Option

It is important to understand that Medicare Advantage is one path — not the only path. Some people find that Original Medicare combined with a Medicare Supplement (Medigap) plan and a standalone Part D drug plan better fits their needs, particularly if they want maximum flexibility in choosing providers without network restrictions.

Neither approach is universally better. The right choice depends on your health, your medications, your doctors, your budget, and how you prefer to access care.

The Bottom Line

Medicare Advantage can be an excellent option for many people — offering extra benefits, predictable out-of-pocket limits, and in many cases, low or no additional premiums. But it works differently from Original Medicare, and the details matter: the network, the drug coverage, the prior authorization policies, and the total costs all play a role.

The Medicare Annual Enrollment Period begins October 15 and runs through December 7. That means now is a great time to learn about your options, review your current coverage, and make sure your plan still fits your needs going into the new year.
