What Are Medicare Advantage Plans (Part C)?

Medicare Advantage Plans, often referred to as Part C, are an alternative way to receive your Medicare benefits. These plans are offered by private companies approved by Medicare. If you enroll in a Medicare Advantage Plan, you still have Medicare, but your plan provides all of your Part A (Hospital Insurance) and Part B (Medical Insurance) benefits.

Unlike Original Medicare, most Medicare Advantage Plans offer additional benefits such as vision, hearing, dental, and wellness programs. Many plans also include Medicare Part D (prescription drug coverage).

Original Medicare vs. Medicare Advantage: Key Differences

Understanding the fundamental differences between Original Medicare and Medicare Advantage is crucial when making your healthcare coverage decision.

How Original Medicare Works

Original Medicare includes Part A (hospital insurance) and Part B (medical insurance). It is managed by the federal government. Generally, you can see any doctor, hospital, or provider nationwide that accepts Medicare. Original Medicare does not cover prescription drugs (unless you enroll in a separate Part D plan) and has no annual limit on out-of-pocket costs.

How Medicare Advantage Plans Work

Medicare Advantage Plans are managed by private insurance companies. When you join a Medicare Advantage Plan, you usually get all your Medicare Part A and Part B services through the plan. Most plans require you to use doctors and hospitals within their network, except in emergencies. These plans must cover all medically necessary services that Original Medicare covers, but they can do so with different rules, restrictions, and costs.

Common Types of Medicare Advantage Plans

Medicare Advantage Plans come in several structures, each with its own rules for how you receive care.

Health Maintenance Organizations (HMOs)

HMO plans typically require you to choose a primary care physician (PCP) within the plan's network. Your PCP coordinates your care and usually needs to provide a referral for you to see specialists. Except for emergencies, you generally must use doctors and hospitals in the plan's network.

Preferred Provider Organizations (PPOs)

PPO plans offer more flexibility than HMOs. You typically don't need a referral to see a specialist, and you can see out-of-network doctors, hospitals, and providers. However, using out-of-network providers usually means paying a higher cost.

Private Fee-for-Service (PFFS) Plans

PFFS plans allow you to see any Medicare-approved doctor or hospital that accepts the plan's terms and conditions. The plan determines how much it will pay for services and how much you must pay for each service.

Special Needs Plans (SNPs)

SNPs are tailored for individuals with specific diseases or characteristics. These plans restrict enrollment to people in certain groups, such as those with chronic health conditions (e.g., diabetes or heart failure), those who live in an institution (like a nursing home), or those eligible for both Medicare and Medicaid.

Benefits and Considerations of Medicare Advantage

Choosing Medicare Advantage involves weighing its potential benefits against important considerations.

Potential Advantages

• Many plans offer extra benefits not covered by Original Medicare, such as routine dental, vision, hearing, and fitness programs.


• Most plans include prescription drug coverage (Part D), simplifying your coverage.


• Medicare Advantage Plans have an annual out-of-pocket maximum, limiting how much you pay for covered Part A and Part B services in a year.

Important Considerations

• You may have to choose doctors and hospitals within the plan's network, which can limit your provider choices.


• Referrals may be required for specialists in some plan types (e.g., HMOs).


• Plans can change their benefits, networks, and costs each year.

Understanding Costs in Medicare Advantage

Costs for Medicare Advantage Plans can vary significantly between plans and providers.

Monthly Premiums

Many Medicare Advantage Plans have a $0 monthly premium beyond your Part B premium. However, some plans do charge an additional premium.

Deductibles, Copayments, and Coinsurance

Like other health insurance, Medicare Advantage Plans often have deductibles (what you pay before the plan starts paying), copayments (a fixed amount you pay for a service), and coinsurance (a percentage of the cost you pay for a service).

Out-of-Pocket Maximum

All Medicare Advantage Plans include an annual limit on your out-of-pocket costs for medical services. Once you reach this limit, the plan pays 100% of your covered Part A and Part B services for the remainder of the year.

Enrolling in a Medicare Advantage Plan

There are specific times when you can enroll in or make changes to your Medicare Advantage Plan.

Initial Enrollment Period (IEP)

This is your first chance to sign up for Medicare. It begins three months before you turn 65, includes the month you turn 65, and ends three months after you turn 65. You can join a Medicare Advantage Plan during this time.

Annual Enrollment Period (AEP)

From October 15 to December 7 each year, you can join, switch, or drop a Medicare Advantage Plan. Your new coverage will begin on January 1 of the following year.

Special Enrollment Periods (SEPs)

In certain situations, like moving to a new area or losing other coverage, you may qualify for a Special Enrollment Period to join, switch, or drop a Medicare Advantage Plan.

Choosing the Right Medicare Advantage Plan

Selecting the best Medicare Advantage Plan involves carefully evaluating your healthcare needs, preferences, and budget. Consider your current doctors, preferred hospitals, prescription medications, health conditions, and how much you are willing to pay in premiums versus out-of-pocket costs. Comparing plans available in your area and understanding their specific benefits and limitations is key to making an informed decision.
