Medicare Supplement Plans Explained: What They Cover & Why You Need One

If you’re enrolled in Original Medicare (Parts A and B), you may already know that it doesn’t cover all of your healthcare costs. That’s where Medicare Supplement Plans, also known as Medigap, come in. These plans help fill the "gaps" left by Medicare, covering out-of-pocket costs like copayments, coinsurance, and deductibles.
​
This guide will explain what Medicare Supplement Plans are, what they cover, and why having one could save you money—and stress—down the road.

What Are Medicare Supplement Plans?
Medicare Supplement Plans are insurance policies sold by private companies to help pay some of the healthcare costs not covered by Original Medicare. These costs include:

• Copayments
• Coinsurance
• Deductibles
• Emergency medical care during international travel

Important: Medigap plans are only available to people enrolled in Original Medicare (Part A and Part B). They do not work with Medicare Advantage (Part C) plans.


What Do Medicare Supplement Plans Cover?
There are several standardized Medigap plans available in most states, labeled Plan A through N. Each offers different levels of coverage. Here are some of the key benefits that most Medigap plans help cover:

1. Part A Coinsurance and Hospital Costs (up to 365 additional days after Medicare benefits are used)
2. Part B Coinsurance or Copayment
3. First 3 Pints of Blood
4. Part A Hospice Care Coinsurance or Copayment
5. Skilled Nursing Facility Coinsurance
6. Part A Deductible
7. Part B Deductible (only Plans C and F, available to those eligible before 2020)
8. Part B Excess Charges
9. Foreign Travel Emergency Coverage (up to plan limits)

Each plan varies, but Plans F, G, and N are among the most popular:

• Plan F (only for those eligible before 2020): Offers the most comprehensive coverage, including both Part A and Part B deductibles.
• Plan G: Similar to F, but doesn’t cover the Part B deductible.
• Plan N: Covers most gaps, but you may pay small copays for doctor visits and emergency room trips.

What Medicare Supplement Plans Don’t Cover
Even the most robust Medigap plans don’t cover everything. You’ll still need to consider other insurance or out-of-pocket costs for:

• Prescription drugs (you’ll need a separate Part D plan)
• Routine dental, vision, and hearing services
• Long-term care
• Private-duty nursing

 Why You Might Need a Medicare Supplement Plan
Here are key reasons to consider getting Medigap coverage:

1. Protect Against High Out-of-Pocket Costs
Medicare can leave you with significant coinsurance or deductible expenses. A Medigap plan can protect you from large and unexpected bills.

2. Predictable Monthly Costs
Medigap plans offer consistent premiums, making budgeting for healthcare easier.

3. Freedom to Choose Providers
With Original Medicare + Medigap, you can visit any doctor or hospital nationwide that accepts Medicare—no networks required.

4. Emergency Travel Coverage
Some Medigap plans offer limited coverage for medical emergencies while traveling abroad, which Original Medicare does not.

5. Guaranteed Renewable
Even if your health changes, as long as you pay your premiums, the plan cannot be canceled by the insurer.


When to Enroll in a Medicare Supplement Plan
The best time to enroll is during your Medigap Open Enrollment Period:

• Begins the first month you're 65 or older and enrolled in Medicare Part B
• Lasts six months
• During this period, you can buy any Medigap plan without medical underwriting

After this period, insurers may deny coverage or charge more based on your health history.


Final Thoughts
Medicare Supplement Plans offer peace of mind by reducing your share of medical costs and giving you freedom in healthcare choices. They’re especially beneficial for individuals with chronic conditions, frequent doctor visits, or those who want predictable healthcare costs in retirement.

Before choosing a plan, compare coverage, premiums, and provider ratings. And always work with a licensed insurance advisor to ensure the plan fits your needs and eligibility.
