Medicare Advantage vs. Medicare Supplement: What’s the Difference?

If you’re approaching 65 or already enrolled in Medicare, you’ve probably heard the terms Medicare Advantage and Medicare Supplement. While both can help cover healthcare costs, they work very differently.

Understanding the difference can make choosing coverage much less confusing.

First: What Is Original Medicare?

Original Medicare includes:

• Part A: Hospital insurance

• Part B: Medical insurance

Original Medicare helps pay for many healthcare services, but it doesn’t pay for everything. You may still have deductibles, coinsurance, and other out-of-pocket expenses.

That’s where Medicare Advantage and Medicare Supplement plans come in.

What Is Medicare Advantage?

Medicare Advantage, also called Medicare Part C, is an alternative way to receive your Medicare benefits.

These plans are offered by private insurance companies approved by Medicare. They typically combine Medicare Part A and Part B coverage into one plan and often include prescription drug coverage.

Many Medicare Advantage plans may also offer additional benefits, depending on the plan, such as:

• Dental coverage

• Vision coverage

• Hearing benefits

• Fitness benefits

• Over-the-counter allowances

One important consideration is the provider network. Depending on the plan, you may need to use certain doctors, hospitals, or pharmacies to receive the lowest costs.

What Is Medicare Supplement?

A Medicare Supplement, also called Medigap, works alongside Original Medicare.

Instead of replacing Original Medicare, a Medigap policy helps pay certain Medicare-covered costs that Original Medicare doesn't fully pay, such as certain deductibles, copayments, and coinsurance, depending on the plan you choose.

You generally can see any doctor or healthcare provider who accepts Medicare patients, which can be an important consideration for people who travel or want broader provider flexibility.

Medigap policies generally do not include prescription drug coverage, so you may need a separate Medicare Part D prescription drug plan.

Medicare Advantage vs. Medicare Supplement

Feature	Medicare Advantage	Medicare Supplement
Works with Original Medicare	No — it replaces how you receive Medicare benefits	Yes
Private insurance company	Yes	Yes
Prescription coverage	Often included	Usually separate Part D plan
Provider networks	Usually yes	Generally no network if provider accepts Medicare
Additional benefits	Often available	Generally focused on Medicare cost-sharing
Monthly premium	Varies by plan; some plans have $0 premiums	Usually an additional monthly premium
Out-of-pocket costs	Generally includes copays/coinsurance and an annual maximum	Helps cover certain Medicare cost-sharing

Plan availability, benefits, premiums, and costs vary by plan and location.

Which One Is Better?

There isn't one answer that is right for everyone.

A Medicare Advantage plan may appeal to someone who wants additional benefits and potentially lower monthly premiums, and who is comfortable using a plan's network and paying copays or coinsurance when receiving care.

A Medicare Supplement plan may appeal to someone who wants greater provider flexibility and more predictable Medicare cost-sharing, and who is comfortable paying an additional monthly premium.

Your doctors, medications, healthcare needs, budget, travel habits, and preferred hospitals can all affect which option makes sense for you.

5 Questions to Ask Before Choosing a Plan

Before enrolling, consider:

1. Are my doctors and hospitals in the plan's network?

2. Are my prescriptions covered and affordable?

3. What will I pay each month?

4. What could I pay out of pocket if I need significant medical care?

5. Does the plan fit the way I expect to use healthcare?

Don't choose a plan based solely on the monthly premium. Looking at the total cost and coverage can give you a much better picture.
