Medicare Supplement (Medigap) Plans: A Complete Guide

Medicare Supplement insurance, also called Medigap, helps fill the "gaps" in Original Medicare coverage. Understanding how Medigap works can help you decide if it's the right choice for your healthcare needs.

What Does Medigap Cover?

Medigap policies help pay for costs that Original Medicare doesn't cover, including:

• Part A and Part B coinsurance and copayments
• Part A and Part B deductibles
• First 3 pints of blood
• Skilled nursing facility coinsurance
• Part B excess charges
• Foreign travel emergency care (up to plan limits)

Standardized Plan Letters

Medigap plans are standardized and named by letters. Each letter offers the same benefits no matter which insurance company sells it. The most common plans are:

Plan G

The most comprehensive plan available to new enrollees. Covers everything except the Part B deductible ($240 in 2024). This is often the most popular choice.

Plan N

Similar to Plan G but with small copays for office visits ($20) and ER visits ($50). Often has lower premiums than Plan G.

High-Deductible Plan G

Same coverage as Plan G, but you pay a high deductible first ($2,800 in 2024). Lower monthly premiums.

When to Enroll in Medigap

Your Medigap Open Enrollment Period is critical:

• Starts when you're 65+ AND enrolled in Part B
• Lasts 6 months
• During this period, you have guaranteed issue rights—companies can't deny you coverage or charge more due to health conditions

Important: After your Open Enrollment Period, companies can use medical underwriting and may deny you coverage based on health conditions.

Medigap vs. Medicare Advantage

You cannot have both Medigap and Medicare Advantage at the same time. Here's how they compare:

• Medigap: Works with Original Medicare, more flexibility, higher premiums, predictable costs
• Medicare Advantage: Replaces Original Medicare, network restrictions, often lower premiums, extra benefits

What Medigap Doesn't Cover

• Prescription drugs (need separate Part D plan)
• Long-term care
• Vision, dental, or hearing
• Private-duty nursing

How to Choose a Medigap Plan

Consider these factors:

• How much are you willing to pay in premiums vs. out-of-pocket costs?
• How often do you see doctors or use medical services?
• Do you travel frequently or live part-time in another state?
• What's your budget for healthcare?
