Short Summary

  • Medicare Advantage plans are private, government-authorized alternatives to Original Medicare that provide additional coverage and perks.

  • It is important to compare costs and assess healthcare needs when selecting the best option for individual health needs.

Understanding Medicare Advantage Plans

Medicare Advantage plans, commonly referred to as ‘Part C’, are a substitute for typical Medicare (Parts A and B). These plans are offered by private companies that are authorized by Medicare.

They are like a one-stop-shop for all your health care needs, offering hospital insurance, outpatient coverage, and often including Part D prescription drug coverage. The benefits don’t stop there. Many Medicare Advantage plans provide additional perks not covered by Original Medicare, like hearing, dental, and vision care.

The private companies offering these plans contract with the federal government to provide you with these benefits. You must be eligible for Original Medicare in order to enroll in a Medicare Advantage plan. Eligibility for one automatically gets you eligibility for the other.

How Medicare Advantage Plans Work

Navigating the healthcare system can be a complex task, but understanding how Medicare Advantage plans work can simplify the process.

Once you’re enrolled in a Medicare Advantage plan, you’ll receive your coverage for hospital visits, outpatient care, and usually prescription drugs all under one plan.

Most Medicare Advantage plans function through a network of providers, meaning you’ll need to use doctors, hospitals, and other providers within the plan’s network.

In some plans, like Health Maintenance Organizations (HMOs), you might need a referral from your own primary care physician or doctor to see a specialist. These plans are designed to manage your care within a specific network of providers, which can help keep costs down.

Types of Medicare Advantage Plans

Not all Medicare Advantage plans are created equal. There are several types of plans, and the one you choose should depend on your individual health needs. Health Maintenance Organizations (HMOs) and Preferred Provider Organizations (PPOs) are two of the most common types of health insurance plans.

These two types offer varying levels of coverage for health care providers and costs. In an HMO, you’ll need to use healthcare providers in the plan’s network, and you’ll likely need a referral to see a specialist.

PPOs offer more flexibility, allowing you to use doctors outside of the plan’s network, but at a higher cost. Other types include Private Fee-for-Service (PFFS) plans and Special Needs Plans (SNPs), which cater to people with specific diseases or characteristics.

Each plan has its own set of rules and costs, so it’s important to understand these before making a decision.

Coverage and Benefits of Medicare Advantage Plans

One of the main reasons Medicare Advantage plans are popular is because of the extensive coverage they provide. In addition to covering hospital and outpatient services that Original Medicare covers, most Medicare Advantage plans also include:

  • Prescription drug coverage (Part D)

  • Dental care

  • Vision care

  • Hearing care

These additional benefits make Medicare Advantage plans a comprehensive option for healthcare coverage.

Some even cover wellness programs and health care services delivered to your home. While the exact benefits vary from plan to plan, the comprehensive coverage offered by these plans can provide peace of mind knowing that most of your healthcare needs will be covered.

Prescription Drug Coverage

Prescription medications can be a significant healthcare expense, especially for those with chronic conditions. That’s why most Medicare Advantage plans include prescription drug coverage, offering prescription drug benefits.

This means that the plan will help pay for your prescription drugs, often for a copayment or coinsurance amount.

The specifics of the coverage, including which drugs are covered and how much you’ll have to pay out-of-pocket, can vary by plan, so it’s essential to review these details when choosing a Medicare Advantage plan.

Additional Benefits

While prescription drug coverage is a significant benefit of many Medicare Advantage plans, they often offer even more benefits. Many plans include additional benefits, like coverage for dental, vision, and hearing care. These are services that Original Medicare doesn’t cover, but are crucial for maintaining overall health.

Some plans even offer coverage for wellness programs, fitness memberships, and other health-related services. It’s these extra benefits that can make Medicare Advantage plans an attractive alternative to Original Medicare.

Comparing Medicare Advantage to Other Medicare Options

Choosing a Medicare plan is a significant decision, and it’s essential to compare all of your options. While Medicare Advantage plans offer a wide range of benefits, they aren’t the only option. Other options include Original Medicare, Medicare Supplement Insurance, and Medicare Part D.

Each of these options has its own set of benefits and trade-offs, and the right choice will depend on your individual health needs and circumstances.

Differences from Original Medicare

While both Medicare Advantage plans and Original Medicare provide coverage for a wide range of healthcare services, there are some key differences.

Unlike Original Medicare, which allows you to use any healthcare provider that accepts Medicare, Medicare Advantage plans typically have a network of providers you must use to get your care.

Additionally, while Original Medicare doesn’t cover most prescription drugs, most Medicare Advantage plans do. Many Medicare Advantage plans provide benefits that are not the same benefits offered by Original Medicare, for example dental, vision, and hearing care. These additional benefits can be an appealing incentive for some.

Differences from Medicare Supplement Insurance

Coverage Aspect Medicare Advantage Medicare Supplement Insurance
Basic Benefits (Part A & B) Covers all Medicare Part A and B benefits Covers some or all out-of-pocket costs associated with Part A and B, depending on the plan
Prescription Drugs (Part D) Most plans offer prescription drug coverage Does not include prescription drug coverage, you would need to buy a separate Part D plan
Additional Services May offer additional benefits not covered by Original Medicare, such as dental, vision, hearing, wellness programs, and even gym memberships Does not offer additional benefits; only helps with costs Original Medicare doesn’t cover
Out-of-Pocket Maximum Has an out-of-pocket maximum, which limits the amount you have to spend on health care in a given year Varies between plans, could be as low as the Part B deductible or up to $4000.00 with a high deductible plan
Cost Monthly premiums can be lower, but you may pay more out of pocket for services you use Usually has a higher monthly premium, but may result in lower out-of-pocket costs overall
Provider Choice Usually requires you to use doctors in the plan’s network (unless it’s an emergency or urgent care situation) You can go to any doctor or hospital that accepts Medicare, anywhere in the U.S.
Travel Coverage is typically limited to your plan’s service area, except for emergencies Coverage is nationwide and some plans offer limited international coverage for emergencies

Medicare Supplement Insurance, also known as Medigap, is another option to consider alongside medical insurance and medical savings accounts.

Unlike Medicare Advantage plans, which replace Original Medicare, Medigap policies supplement your Original Medicare benefits. They help pay for out-of-pocket costs that Original Medicare doesn’t cover, like copayments, coinsurance, and deductibles.

However, they don’t usually offer extra benefits like dental, vision, and hearing care, which many Medicare Advantage plans do.

Differences from Medicare Part D

Medicare Part D is a standalone prescription drug plan that adds drug coverage to Original Medicare. Unlike Medicare Advantage plans, which often include prescription drug coverage, Medicare Part D is separate and only covers drugs.

So if you choose Original Medicare and want drug coverage, you’ll need to add a Part D plan.

On the other hand, if you choose a Medicare Advantage plan, you’ll likely get prescription drug coverage included in your plan.

Choosing the Right Medicare Advantage Plan

Once you understand what Medicare Advantage plans are and how they compare to other options, the next step is to compare Medicare Advantage plans and choose the right one for you. But with so many plans out there, how do you choose?

The key is to consider your individual healthcare needs, check the provider networks, and compare the costs.

Assessing Your Healthcare Needs

Your healthcare needs are a crucial factor in choosing a Medicare Advantage plan. Consider the types of services you need and how often you need them. Do you need prescription drugs? Do you need regular check-ups or specialty care?

Also, consider any health conditions you have. Some plans, like Special Needs Plans, cater to people with specific diseases or characteristics. By understanding your healthcare needs, you can choose a plan that provides the right coverage for you.

Checking Provider Networks

Another important factor to consider is the provider network. Medicare Advantage plans often have a network of doctors, hospitals, and other healthcare providers that you must use to get your care.

So, it’s crucial to check if your preferred doctors and hospitals are in the plan’s network. If they aren’t, you might have to choose new medical providers or pay more to see your preferred ones.

It’s important to research the provider network before signing up for a plan. Make sure your family is safe.

Comparing Costs

Costs are another significant consideration when choosing a Medicare Advantage plan. These can include:

  • Premiums

  • Deductibles

  • Copayments

  • Coinsurance

Consider how much you can afford to pay out-of-pocket and compare the costs of different plans.

Keep in mind that a plan with a low premium may have higher out-of-pocket costs when you need care. So, it’s important to consider all costs, not just the monthly premium alone.

Enrollment and Switching Medicare Advantage Plans

After you’ve chosen a Medicare Advantage plan, the next step is to enroll. But when can you enroll, and what if you want to switch plans later?

In this section, we’ll answer these questions and provide information on the enrollment process.

How to Enroll

Enrolling in a Medicare Advantage plan is easier than you might think. You can enroll in the following ways:

  • Online: Go to the plan’s website and follow the instructions.

  • By phone: Call the plan’s enrollment hotline and provide the necessary information.

  • By filling out an enrollment form: Obtain an enrollment form from the plan or request one to be mailed to you.

To enroll by phone, you can call the plan directly, or you can call Medicare at 1-800-MEDICARE. If you prefer to fill out a form, you can contact the plan and ask for an enrollment form.

When to Enroll

There are specific times when you can enroll in a Medicare Advantage plan. When you first become eligible for Medicare, you can enroll during your Initial Enrollment Period, which starts three months before you turn 65 and ends three months after you turn 65.

After that, you can enroll or switch plans during the Annual Enrollment Period, which runs from October 15 to December 7 each year. There’s also an Open Enrollment Period from January 1 to March 31 each year when you can switch plans or return to Original Medicare.

Switching Plans

Life changes, and so do your healthcare needs. That’s why it’s good to know that you can switch Medicare Advantage plans if needed. You can switch plans during the Annual Enrollment Period or the Open Enrollment Period.

If you move out of your plan’s service area, or if you qualify for a Special Enrollment Period, you can also switch plans. To switch plans, you can use the same methods as when you first enrolled—online, by phone, or by filling out a form.

Medicare Advantage Plan Disadvantages and Considerations

While Medicare Advantage plans offer many benefits, they’re not for everyone. Like any health insurance plan, they have disadvantages and limitations that you should be aware of. Understanding these can help you make an informed decision when choosing a plan.

It’s important to consider the cost of the plan and the other health coverage it provides.

Potential Limitations

One potential limitation of Medicare Advantage plans is their restricted provider networks. Unlike Original Medicare, which allows you to see any doctor who accepts Medicare, Medicare Advantage plans often require you to use providers in their network. This can limit your choice of doctors and hospitals.

Additionally, some plans may have yearly caps on out-of-pocket expenses, which can limit your financial protection if you need a lot of care. Finally, the benefits of a plan can change from year to year, which could affect your coverage and costs.

Preexisting Conditions

If you have a preexisting condition, you may have additional considerations when choosing a Medicare Advantage plan. It’s important to make sure the plan covers the services and medications you need for your condition.

Additionally, while Medicare Advantage plans can’t deny you coverage based on your health, if you want to switch back to Original Medicare and buy a Medigap policy, the insurer can use medical underwriting. This could result in higher premiums or a denial of coverage based on your health.


Choosing a Medicare Advantage plan is a significant decision that can impact your health and finances. While these plans offer many benefits, including comprehensive coverage, additional benefits, and often lower costs, they also have potential disadvantages and limitations.

Understanding these factors can help you make an informed decision and choose a plan that best meets your needs. So take your time, do your research, and make a choice that will ensure your health is well taken care of.

Medicare Advantage is a type of health plan offered by private companies that contract with Medicare to provide you with all your Part A and Part B benefits. It offers an alternative to Original Medicare for health and drug coverage, combining Part A and Part B into one plan along with prescription drugs in some cases.

Generally, you can only use doctors who are in the plan’s network.

Do you still pay Medicare premiums with an Advantage plan?

Yes, you still have to pay the Medicare Part B premium in addition to a possible Medicare Advantage plan premium, which can range from $0 to over $100 a month.
