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

If you’re turning 65 or helping a loved one with Medicare decisions, you’ve probably already run into two confusing terms: Medicare Advantage and Medicare Supplement (also called Medigap). While they sound similar, these two types of plans work very differently—and choosing the right one can make a big difference in your healthcare and your wallet.

At Richie Insurance Solutions here in Kokomo, Indiana, we help people every day who feel overwhelmed by these options. So let’s break it down in simple terms.

Original Medicare: The Starting Point

Before we talk about Advantage vs. Supplement, it’s helpful to understand Original Medicare, which includes:

• Part A – Hospital insurance

• Part B – Medical insurance

Original Medicare helps cover hospital and doctor visits, but it doesn’t pay for everything. You’re responsible for deductibles, coinsurance, and other out-of-pocket costs. That’s where Advantage and Supplement plans come in—to help cover the gaps.

What Is Medicare Advantage (Part C)?

Medicare Advantage plans are offered by private insurance companies that are approved by Medicare. When you join a Medicare Advantage plan, it becomes your primary insurance instead of Original Medicare.

Here’s how it works:

• You still have Medicare, but your benefits are now administered by a private plan, not the government.

• These plans often bundle Part A, Part B, and sometimes Part D (prescription drugs).

• Many include extra benefits like dental, vision, hearing, and gym memberships.

• Most Medicare Advantage plans require you to use a network of doctors and may need referrals for specialists.

Think of it like an all-in-one package—it might cost less monthly, but you’ll have copays and need to follow plan rules.

What Is a Medicare Supplement (Medigap) Plan?

Medicare Supplement plans work alongside Original Medicare. Instead of replacing it, they help cover the “gaps”—like deductibles, coinsurance, and copays.

Here’s what to know:

• You can see any doctor or hospital in the U.S. that accepts Medicare—no networks.

• You’ll typically have higher monthly premiums, but lower out-of-pocket costs when you receive care.

• Prescription drug coverage is not included, so you’ll need a separate Part D plan.

• Plans are standardized (Plan G, Plan N, etc.), which makes comparing them easier.

Think of it as peace of mind and flexibility—especially if you travel or want fewer billing surprises.

Key Differences at a Glance

Feature	Medicare Advantage	Medicare Supplement
Doctor Choice	Network-based (HMO/PPO)	Any provider that accepts Medicare
Referrals Needed	Often yes	No
Prescription Drugs	Often included	Not included
Monthly Premiums	Usually lower	Usually higher
Out-of-Pocket Costs	Copays, coinsurance	Minimal after premiums
Extra Benefits	Often included	Rarely included

Which One Is Right for You?

The answer depends on your budget, lifestyle, health needs, and doctor preferences. For example:

If you travel often or want to see any doctor who accepts Medicare, a Supplement plan might be best.

If you want lower monthly premiums and are okay with staying in-network, a Medicare Advantage plan may be a good fit.

That’s why working with a local Medicare advisor in Kokomo—someone who understands both the plans and the local providers—can make this choice much easier.
