The Biggest Decision in Medicare

After enrolling in Original Medicare (Parts A & B), you face the most important decision in your Medicare journey: How do you want to fill the gaps?

You have two paths — and they work very differently:

Medicare Advantage (Part C) — replaces Original Medicare with a private plan that bundles everything
Medigap (Medicare Supplement) — keeps Original Medicare and adds a separate policy to cover what Medicare doesn’t

Neither option is universally “better.” The right choice depends on your health, your budget, and how you use healthcare.

Side-by-Side Comparison

Feature	Medicare Advantage	Medigap
How it works	Replaces Original Medicare	Supplements Original Medicare
Monthly premium	Often $0 (in addition to Part B)	$50–$300+ depending on plan & age
Doctor choice	Network required (HMO/PPO)	Any Medicare-accepting provider
Out-of-pocket maximum	Yes — $3,000–$8,000/year typical	Plan G: only $240 deductible/year
Drug coverage	Usually included	Requires separate Part D plan
Dental/Vision/Hearing	Often included	Not included — need separate plans
Prior authorization	Often required	Never required
Travel coverage	Limited (usually no out-of-area coverage)	Nationwide coverage
Best for	Healthy, budget-conscious, like extra benefits	Frequent healthcare users, travelers, want predictability

When Medicare Advantage Makes Sense

✅ You want low or $0 monthly premiums
✅ You value extra benefits (dental, vision, hearing, gym, OTC allowance)
✅ Your doctors are in the plan’s network
✅ You’re relatively healthy and don’t see specialists frequently
✅ You don’t travel extensively or need nationwide coverage
✅ You prefer one card, one plan simplicity

When Medigap Makes Sense

✅ You want predictable, low out-of-pocket costs
✅ You see multiple specialists or have chronic conditions
✅ You travel frequently or split time between states
✅ You want to see any doctor who accepts Medicare, anywhere
✅ You don’t need prior authorization for referrals or procedures
✅ You’re willing to pay a higher monthly premium for greater certainty

💡 The key insight: Medicare Advantage shifts risk to you (low premiums but potentially high costs if you get sick). Medigap shifts risk to the insurer (higher premiums but your costs are predictable no matter what happens).

The Medigap Enrollment Warning

Here’s something many people don’t realize until it’s too late:

You get one guaranteed-issue window for Medigap — the 6 months starting when you turn 65 and are enrolled in Part B. During this window, insurers must accept you at standard rates regardless of health.

After this window closes, insurers in most states (including North Carolina) can:

❌ Deny your application based on health conditions
❌ Charge higher premiums based on medical history
❌ Exclude coverage for pre-existing conditions

This means if you choose Medicare Advantage now and want to switch to Medigap later, you may not be able to get it — or it may cost significantly more.
