What is Medicare Advantage? Your Complete Guide

Navigating Medicare as you approach 65 or reassessing your coverage options during open enrollment, can bring up plenty of questions. As you consider your plan options one of the choices you'll encounter is Medicare Advantage, a popular alternative to Original Medicare. But what exactly is Medicare Advantage, and how do you know if it's right for you?

Medicare Advantage (also called Medicare Part C or MA) is a comprehensive healthcare plan offered by private insurance companies approved by Medicare. Instead of having separate coverage for hospital care (Part A) and medical services (Part B), Medicare Advantage bundles these benefits into one plan. Most MA plans also include prescription drug coverage (Part D) and often provide extra benefits that Original Medicare doesn't cover.

Think of Medicare Advantage as a managed care approach to Medicare. Rather than the government directly paying your healthcare providers, you receive your Medicare benefits through a private insurance company that contracts with Medicare. These companies receive a set amount from Medicare to cover your healthcare costs and must provide at least the same benefits as Original Medicare.

This guide will walk you through everything you need to know about Medicare Advantage, from eligibility requirements to choosing the right plan for your needs. Our goal is to provide you with clear, unbiased information so you can make confident decisions about your healthcare coverage.

Who Can Enroll in Medicare Advantage and When?

To enroll in a Medicare Advantage plan, you must first be eligible for Medicare. This means you're either 65 or older, have a qualifying disability, or have End-Stage Renal Disease or ALS. You must also be enrolled in both Medicare Part A and Part B, and you cannot have a Medicare Supplement (Medigap) policy at the same time as a Medicare Advantage plan.


Key Enrollment Periods

Initial Enrollment Period (IEP): When you first become eligible for Medicare, you have a seven-month window to choose your coverage. This period begins three months before you turn 65, includes your birthday month, and continues for three months after.

Annual Open Enrollment Period: From October 15 to December 7 each year, you can switch from Original Medicare to Medicare Advantage, change from one MA plan to another, or return to Original Medicare. Changes take effect January 1.


Medicare Advantage Open Enrollment Period
: If you're already in a Medicare Advantage plan, you have an additional opportunity from January 1 to March 31 to switch to a different MA plan or return to Original Medicare with or without a Part D plan.


Special Enrollment Periods
: Certain life changes, such as moving to a new area, losing other health coverage, or qualifying for financial assistance, may give you a Special Enrollment Period to make changes outside the standard enrollment windows.

What Does Medicare Advantage Cover?

Medicare Advantage plans must cover everything that Original Medicare covers, but they often provide much more. Understanding what's included can help you see the value these plans offer.

Standard Medicare Benefits

All MA plans include hospital insurance (Part A) and medical insurance (Part B). This covers hospital stays, doctor visits, outpatient services, preventive care, and medically necessary equipment and supplies.

Prescription Drug Coverage

Most Medicare Advantage plans include Part D prescription drug coverage built right into the plan. This eliminates the need to purchase a separate Part D plan and often provides better coordination between your medical and prescription benefits.

Extra Benefits Beyond Original Medicare

This is where Medicare Advantage plans really shine. Many plans offer additional benefits that can significantly enhance your healthcare experience:

Vision Care: Routine eye exams, glasses, and contact lenses that Original Medicare doesn't cover.

Dental Care: Preventive dental services, cleanings, fillings, and sometimes major dental work.

Hearing Services: Hearing aids, exams, and fittings that can save you thousands of dollars.

Wellness Programs: Gym memberships, fitness classes, nutrition counseling, and health coaching to help you stay healthy.

Transportation Services: Rides to medical appointments, which can be especially valuable if you no longer drive.

Over-the-Counter Allowances: Monthly credits to purchase health-related items like vitamins, first aid supplies, and personal care products.

Understanding Medicare Advantage Costs

One of the most appealing aspects of Medicare Advantage is the potential for cost savings, but it's important to understand how these plans structure their costs.

Monthly Premiums

Many Medicare Advantage plans have $0 monthly premiums beyond what you already pay for Medicare Part B. However, you'll still pay your Part B premium (which will be $206.50 for most people in 2026). Some MA plans do charge additional monthly premiums, especially those with extensive extra benefits.

Out-of-Pocket Costs

While premiums might be low, you'll typically pay copays or coinsurance when you use services. For example, you might pay $20 for a primary care visit or $40 for a specialist visit. The good news is that Medicare Advantage plans have annual out-of-pocket maximums that limit your total costs each year.

Annual Out-of-Pocket Maximums

Unlike Original Medicare, which has no limit on your out-of-pocket costs, Medicare Advantage plans cap your annual expenses. For 2026, this limit cannot exceed $9,250 for in-network services. Once you reach this limit, the plan pays 100% of covered services for the rest of the year.

Cost Variations

Your actual costs will depend on factors like your plan's provider network, your health needs, and whether you stay within the plan's network of doctors and hospitals.

Types of Medicare Advantage Plans

Medicare Advantage plans come in different structures, each with its own approach to managing your care and costs.

Health Maintenance Organization (HMO) Plans

HMO plans typically offer the lowest costs but require you to stay within a specific network of providers. You'll usually need to choose a primary care physician who coordinates your care and provides referrals to specialists. If you go outside the network without prior approval, you'll likely pay the full cost.

Preferred Provider Organization (PPO) Plans

PPO plans offer more flexibility by allowing you to see any Medicare-approved provider, though you'll pay less if you stay within the plan's preferred network. You typically don't need referrals to see specialists, giving you more control over your healthcare decisions.

Private Fee-for-Service (PFFS) Plans

These plans determine how much they'll pay providers and how much you'll pay for services. You can see any provider that accepts the plan's terms, but both you and your provider must agree to the plan's payment structure.

Special Needs Plans (SNPs)

SNPs are designed for people with specific chronic conditions, those who qualify for both Medicare and Medicaid, or individuals living in institutions. These plans tailor their benefits, provider networks, and drug formularies to meet the unique needs of their members.

Weighing the Advantages and Disadvantages of a Medicare Advantage Plan

Like any healthcare option, Medicare Advantage has both benefits and potential drawbacks to consider.

Advantages

Comprehensive Coverage: Having medical, hospital, and often prescription drug coverage in one plan simplifies your healthcare management.

Extra Benefits: Services like dental, vision, and wellness programs can provide significant value and improve your overall health.

Cost Predictability: Out-of-pocket maximums give you financial protection and help you budget for healthcare costs.

Care Coordination: Many plans focus on coordinating your care to improve outcomes and prevent gaps in treatment.

Disadvantages

Network Restrictions: You may be limited to specific doctors and hospitals, and going outside the network can be expensive.

Prior Authorization Requirements: Some services may require approval from the plan before you can receive them.

Plan Changes: Insurance companies can change benefits, costs, and provider networks each year.

Geographic Limitations: If you travel frequently or spend part of the year in different states, network limitations could affect your access to care.

How to Decide on a Medicare Advantage Plan

Selecting a Medicare Advantage plan requires careful consideration of your healthcare needs, budget, and preferences.

Assess Your Healthcare Needs

Start by evaluating your current health status and medical needs. Do you take regular medications? Do you have ongoing relationships with specific doctors? Are there services you wish you had better coverage for, like dental or vision care?

Check Provider Networks

Make sure your preferred doctors and hospitals are in the plan's network. If maintaining relationships with current providers is important to you, this should be a top priority in your decision-making.

Review Plan Benefits and Costs

Look beyond the monthly premium to understand the total cost of care. Consider copays, coinsurance, deductibles, and the out-of-pocket maximum. Factor in any extra benefits that could provide value for your situation.

Examine Prescription Drug Coverage

If you take medications, check that they're covered by the plan's formulary and understand what you'll pay for them. The lowest-premium plan isn't always the best choice if your drugs are expensive under that plan.

Consider Your Budget

Think about both your monthly budget for premiums and your ability to handle unexpected medical expenses up to the plan's out-of-pocket maximum.

Making Changes to Your Medicare Advantage Plan

Your healthcare needs and circumstances can change, and Medicare provides opportunities to adjust your coverage accordingly.

Annual Review Process

Each fall, review your current plan's materials for the upcoming year. Plans can change their benefits, costs, and provider networks, so what worked well this year might not be the best choice for next year.

Switching Plans

During the Annual Open Enrollment Period (October 15 to December 7), you can switch to a different Medicare Advantage plan or return to Original Medicare. If you're already in a Medicare Advantage plan, you have an additional opportunity during the Medicare Advantage Open Enrollment Period (January 1 to March 31).

Returning to Original Medicare

If you decide Medicare Advantage isn't right for you, you can switch back to Original Medicare. However, if you want to add a Medigap policy, you may have to answer health questions or face higher premiums unless you qualify for guaranteed issue rights.
