Medigap Insurance: Understanding the Basics of Medicare Supplement Plans

Why Medigap Insurance Matters for Your Retirement

Medicare coverage is essential for staying healthy and financially independent during retirement, but Medicare alone doesn’t cover every healthcare expense you’ll face. Understanding how Medigap insurance works can help Fort Myers and Southwest Florida retirees fill those gaps before unexpected costs arise.

Medigap insurance, also known as Medicare Supplement insurance, is available for purchase by individuals age 65 and older to supplement Original Medicare.

What Does Medigap Insurance Cover?

A Medigap policy is designed to help cover the costs Original Medicare leaves behind, including:

• Copayments
• Coinsurance
• Deductibles

It’s important to understand one key detail about how Medigap insurance works: coinsurance is typically only covered after you’ve paid your deductible, unless you select a Medigap policy that also covers the deductible itself.

Understanding Medigap Plan A Through N

Medigap is private health insurance, but it’s regulated by federal and state laws designed to protect consumers. In most states, Medigap policies are only sold as standardized packages, each identified by a letter from A through N.

Here’s what that standardization means for you:

• Every insurance company offering a specific lettered plan (for example, Plan G) must include the same basic benefits
• Cost is usually the only difference between two companies’ versions of the same lettered plan
• All insurance companies are required to offer Plan A
• Each Medigap plan option (A through N) differs in the benefits it offers and the percentage of coverage provided for Medicare’s gaps

When to Buy Medigap: Why Timing Matters

You must already have Medicare Part A and Part B to purchase a Medigap policy. Timing your purchase correctly is one of the most important decisions you’ll make.

The Medigap Open Enrollment Window

The best time to buy Medigap insurance is during your Medigap open enrollment period—the six-month window that begins once you’re both 65 or older and enrolled in Medicare Part B.

Buying during this window means:

• You generally will not need to undergo medical underwriting
• If you have existing health conditions, you can still buy a policy at the same price offered to people in good health

Missing this window can make it more difficult—or in some cases impossible—to qualify for coverage later, particularly if health issues develop after your initial eligibility period.

One Policy Per Spouse

Medigap eligibility and coverage apply on an individual basis. If you’re married, each spouse must purchase a separate Medigap policy—there’s no joint or family Medigap plan.
