Medicare Advantage vs. Medicare Supplement Plans

If you’re approaching Medicare eligibility, you’ve probably discovered that your choices don’t stop at Original Medicare (Parts A & B). Most people realize they’ll need additional coverage, either through a Medicare Advantage (Part C) plan or a Medicare Supplement (Medigap) policy.

Both options are designed to help protect your health and your wallet—but they work very differently. Choosing between them is one of the most important Medicare decisions you’ll make, and it can affect everything from your monthly costs to which doctors you can see.

At Solutions to Medicare, we’ve been guiding seniors in Georgia and surrounding areas for over a decade, and here’s what you should know before deciding.

Medicare Advantage, also called Part C, is offered by private insurance companies approved by Medicare. Instead of using Original Medicare, you receive your benefits through the Advantage plan.

Key Features of Medicare Advantage Plans:

Includes all the coverage of Parts A & B (hospital and medical insurance)
Often includes prescription drug coverage (Part D)
May bundle in extra benefits like dental, vision, hearing aids, transportation, or fitness memberships
Usually requires using a network of doctors, hospitals, and pharmacies
Costs include monthly premiums, copays, and coinsurance

Many people choose Medicare Advantage because it feels familiar—it operates like the employer health plans they’ve had in the past, with a single card, one network, and all-in-one benefits.

Medicare Supplement Insurance (Medigap) works alongside Original Medicare. You keep Parts A & B, and your Medigap plan helps cover the “gaps” that Medicare leaves behind.

Key Features of Medigap Plans:

Helps pay deductibles, copayments, and coinsurance
Works with any doctor or hospital nationwide that accepts Medicare—no networks
Doesn’t typically include extras like dental or vision
Requires an additional monthly premium (on top of your Part B premium)
Gives you more predictable healthcare costs

People who want flexibility and travel often prefer Medigap, since it allows you to see specialists and providers across the country without referrals.
