Choosing the right Medicare coverage can be confusing, especially when you’re faced with multiple plan options. While Original Medicare helps cover many healthcare expenses, it doesn’t pay for everything. That’s where Medicare Supplement plans—also known as Medigap—come in.
In this complete guide, we’ll break down a Medicare Supplement plan comparison, explain how each plan works, and help you choose the best option for your needs in 2026.
🏥 What Is Medicare Supplement Insurance?
Medicare Supplement Insurance (Medigap) is a private insurance policy that helps cover costs not paid by Original Medicare, such as:
- Copayments
- Coinsurance
- Deductibles
These plans are standardized and regulated, making it easier to compare options.
🧾 Why Do You Need a Medigap Plan?
Original Medicare (Part A & Part B) doesn’t cover all medical expenses.
Coverage Gaps Include:
- Hospital deductibles
- Skilled nursing coinsurance
- Foreign travel emergencies
Medigap helps fill these gaps, reducing out-of-pocket costs.
📊 How Medicare Supplement Plans Work
- You must have Original Medicare
- You pay a monthly premium
- Medigap pays its share after Medicare
👉 You can visit any doctor who accepts Medicare.
