by Medicare doesn’t cover everything — and for retirees living on fixed incomes, that gap can be costly. While Medicare takes care of a large portion of hospital and medical expenses, it only covers about 80% of approved costs. The remaining 20%—plus services like dental, vision, and hearing—often leave seniors surprised by out-of-pocket bills.
Let’s break down what Medicare really covers, when Medigap might be worth it, and when you might not need the extra cost.
What Original Medicare Actually Covers
Original Medicare includes Part A (hospital care) and Part B (doctor visits and outpatient services). It’s a strong foundation, but far from comprehensive.
Here’s what it does not cover:
- Dental care (routine cleanings, fillings, dentures)
- Vision exams or glasses
- Hearing aids
- Long-term care
- Prescription drugs (you need a separate Part D plan for that)
On top of that, retirees must pay deductibles, copayments, and coinsurance for many services. A hospital stay, for example, can easily add up to thousands of dollars in uncovered costs.
And because health needs tend to increase with age, these small gaps can quickly become financial burdens.
Where Supplemental (Medigap) Insurance Fits In
That’s where Medigap—private insurance that supplements Medicare—comes in. These policies are designed to fill the financial “gaps” left by Original Medicare, covering copays, deductibles, and coinsurance.
For retirees with chronic conditions or ongoing treatments, Medigap can provide peace of mind. Knowing that you won’t be hit with unexpected hospital bills can be worth the cost of a monthly premium, which typically starts around $150–$200 depending on the plan and state.
But Medigap isn’t for everyone—and that’s where confusion begins.
Insurers and the Fear Factor
For many older adults, the U.S. health insurance system feels like a maze of forms, jargon, and fine print. Companies know this—and often use fear-based marketing to push retirees into buying plans they may not actually need.
Commercials and mailers warn about “financial ruin” from hospital bills or emergencies. What they don’t mention is that some people do perfectly fine with just Original Medicare, especially if they’re generally healthy and have some savings to cover occasional copays.
That fear can lead to over-insurance, where seniors pay hundreds more each month “just in case,” without ever using the benefits they’re buying.
When Medigap Makes Sense — and When It Doesn’t
Consider Medigap if:
- You have chronic illnesses or need frequent medical care.
- You don’t have other insurance (like from a former employer or spouse).
- You prefer freedom to see any doctor who accepts Medicare nationwide.
- You want predictable healthcare costs with fewer surprises.
You may not need Medigap if:
- You’re in good health and only see a doctor occasionally.
- You have enough savings to handle deductibles or copays.
- You already have coverage through Medicare Advantage (Part C) or another plan.
Some retirees even set up a small medical emergency fund instead of paying monthly premiums for years. For them, the math simply works out better.

Medigap vs. Medicare Advantage: Know the Difference
Medigap and Medicare Advantage (Part C) are often confused, but they work very differently.
- Medigap supplements Original Medicare and lets you see any provider who accepts Medicare anywhere in the U.S.
- Medicare Advantage, on the other hand, replaces Original Medicare entirely and usually limits you to specific provider networks. It’s often cheaper up front but can come with more restrictions.
Neither option is automatically “better.” The right choice depends entirely on your health needs, finances, and comfort level with risk.
The Bottom Line: It’s a Personal Decision
Medigap isn’t good or bad—it’s about what’s right for you.
If you value extra security and can afford it, go for it. If you’re healthy, financially prepared, and comfortable managing occasional medical bills, Original Medicare alone might be enough.
The real issue is clarity. Retirees shouldn’t need to become insurance experts just to avoid being overcharged or underinsured. Until the system becomes simpler and more transparent, older Americans will remain caught between the fear of being unprotected and the frustration of paying too much.
