How do Medicare Advantage Plans Work?

Navigating the complex landscape of Medicare can be daunting, especially with the various options available to beneficiaries.

One popular alternative to Original Medicare is Medicare Advantage (MA) plans. Understanding how Medicare Advantage plans work is important for individuals seeking comprehensive healthcare coverage tailored to their unique needs.

In this comprehensive guide, we will delve into the intricacies of Medicare Advantage plans, providing valuable insights to help you make informed decisions about your healthcare coverage.

What Are Medicare Advantage Plans?


Medicare Advantage plans, or Medicare Part C, are private health insurance plans approved by Medicare. These plans combine the benefits of Original Medicare (Part A and Part B) and often include additional coverage, such as vision, dental, and prescription drug benefits.

Unlike Original Medicare, which the federal government administers, Medicare Advantage plans are offered by private insurance companies approved by Medicare. If you sign up for an Advantage plan, that plan is responsible for managing your care, not Original Medicare.

Advantage plans are also not to be confused with Medigap plans. Many people wonder “Is Plan G a Medicare Advantage plan?” but they are two separate types of plans.

Key Features of Medicare Advantage Plans

All-in-One Coverage

One of the primary advantages of Medicare Advantage plans is that they provide what you can consider all-in-one coverage. This means beneficiaries receive inpatient (Part A) and outpatient (Part B) coverage, and often prescription drug (Part D) coverage, through a single plan.

Some plans even offer additional benefits like vision, dental, and wellness programs, providing comprehensive healthcare solutions. However, it’s good to keep in mind that Advantage plans can change their benefits each year. Because of this, it’s best not to base your plan decision on additional benefits.

Network-Based Care

Medicare Advantage plans typically operate within provider networks. Beneficiaries may need to choose healthcare providers, doctors, and hospitals within the plan’s network to receive full coverage.

While emergency and urgently needed care are exceptions and can be accessed outside the network in most plans, staying within the network often results in lower out-of-pocket costs.

Cost-Effective Options

Medicare Advantage plans often come with cost-saving features, such as annual out-of-pocket maximums. Once you reach this limit, the plan covers all approved medical costs for the remainder of the year, offering financial protection and peace of mind.

Some Advantage plans may even have a $0 monthly premium in exchange for a higher out-of-pocket maximum.

The Kinds of Medicare Advantage Plans


There are several kinds of Medicare Advantage plans, each designed to meet different healthcare needs.

Health Maintenance Organization (HMO) Plans

With HMO plans, beneficiaries typically need to select a primary care physician (PCP) and receive referrals from their PCP to see specialists. These plans often have lower monthly premiums but have a more restricted network.

Preferred Provider Organization (PPO) Plans

PPO plans typically offer more flexibility in choosing healthcare providers as they don’t require you to choose a PCP. Beneficiaries can see specialists without referrals, both in-network and out-of-network. However, if you go out-of-network, your costs may be higher.

So, while premiums and out-of-pocket costs might be higher, beneficiaries have greater freedom in selecting healthcare providers.

Private Fee-for-Service (PFFS) Plans

Like PPO plans, PFFS plans do not require you to choose a PCP. PFFS plans determine how much they will pay healthcare providers and how much beneficiaries are responsible for. Some PFFS plans have networks, while others allow beneficiaries to see any Medicare-approved provider who accepts the plan’s terms.

Special Needs Plans (SNPs)

SNPs are tailored for individuals with specific health conditions or circumstances, such as chronic illnesses or Medicaid benefits. These plans offer specialized, coordinated care to meet the unique needs of the beneficiaries they serve.

Enrollment and Eligibility

To enroll in a Medicare Advantage plan, individuals need Medicare Part A and Part B and typically need to live within the plan’s service area. You must also be a U.S. citizen or have a lawful presence in the U.S.

Choosing the Right Medicare Advantage Plan


Selecting the right Medicare Advantage plan involves careful consideration of individual healthcare needs and preferences. Here are some factors to consider when choosing a plan.


Evaluate the plan’s coverage, including medical services, prescription drugs, and additional benefits. Ensure the plan covers essential services and medications you may need.


Consider the plan’s provider network. If you have preferred doctors or specialists, ensure they are within the plan’s network to avoid additional costs. If you prefer to have more freedom with your providers, Original Medicare and a Medigap plan may be a better fit for you.


Compare premiums, deductibles, copayments, and out-of-pocket maximums. Calculate potential costs based on your expected healthcare usage to determine the plan’s affordability.

Additional Benefits

Some Medicare Advantage plans offer extra benefits like dental, vision, hearing, and wellness programs. Assess these benefits to determine their value to your overall healthcare needs. However, remember to keep in mind that these benefits can change from year to year.

Star-Ratings and Reviews

Medicare provides star ratings for Medicare Advantage plans based on factors like customer satisfaction and quality of care. Researching these ratings can provide insights into the plan’s performance and customer satisfaction.
