Understanding Medigap: Medicare Supplement Insurance Explained

Medicare can be a lifesaver—but it doesn’t cover everything. That’s where Medigap, also known as Medicare Supplement Insurance, comes into play. If you’re navigating Medicare in Aiken, SC, understanding Medigap plans is essential to managing your healthcare expenses.

At Navigating My Medicare, we help you find the right plan to close those coverage gaps with expert guidance and personal support.

What is Medigap?

Medigap is private health insurance that helps pay for out-of-pocket costs not covered by Original Medicare. These may include:

• Copayments
• Coinsurance
• Deductibles
• Emergency foreign travel costs

Medigap policies are standardized and regulated by federal and state governments, ensuring consistent coverage across plans.

How Does Medigap Work with Medicare?

Medigap is designed to complement Original Medicare (Part A and Part B).

Here’s how it works:

Feature	Original Medicare	Medigap
Primary Coverage	Yes	Secondary (fills gaps)
Network Restrictions	No	No (works nationwide)
Referrals Required	No	No
Prescription Drugs	No	No (you’ll need Part D)

Medigap only works with Original Medicare—not with Medicare Advantage Plans.
