Quick answer

Medigap pairs with Original Medicare for nationwide provider access, no networks, and predictable costs, but charges a monthly premium. Medicare Advantage often has $0 premiums and bundles extras like dental, but uses networks, referrals, and prior authorization. You can't have both at once, per Medicare.gov.

Medigap and Medicare Advantage are two very different ways to receive your Medicare benefits. Here's how to choose between them.

What's the core difference?

Medigap works with Original Medicare: the government pays your claims, and your Medigap policy covers the leftover costs. You can see any provider nationwide that accepts Medicare, with no networks or referrals, and you add a standalone Part D plan for drugs. Medicare Advantage replaces Original Medicare with a private plan that bundles your coverage, often including drugs and extras like dental and vision, but restricts you to a network and may require prior authorization. The trade-off is freedom and predictability (Medigap) versus low upfront premiums and bundled extras (Advantage). Our agents explain both sides honestly, call 1-800-MEDIGAP (1-800-633-4427).

How do the costs compare?

Medigap charges a monthly premium (often $90 to $300+ for Plan G) on top of your Part B premium, but then leaves you with minimal out-of-pocket costs when you receive care. Medicare Advantage often advertises $0 premiums, but you pay copays and coinsurance as you use services, up to an annual out-of-pocket maximum that can reach several thousand dollars. So Medigap front-loads cost into a predictable premium, while Advantage shifts cost to when you're sick. Which is cheaper overall depends on how much care you use. Call 1-800-MEDIGAP to model both scenarios for your situation.

Which should you choose?

Choose Medigap if you value seeing any doctor nationwide, travel often, have chronic conditions, or want predictable budgeting without prior-authorization hurdles. Choose Medicare Advantage if you want the lowest possible premium, like bundled extras such as dental and vision, and are comfortable using a network. Importantly, switching from Advantage to Medigap later may require medical underwriting, so your initial choice matters. A licensed agent at 1-800-MEDIGAP can weigh your doctors, medications, travel habits, and budget to recommend the right path, at no cost.

Frequently asked questions

Can I have both Medigap and Medicare Advantage?+

No. You cannot use a Medigap policy with a Medicare Advantage plan, and it's illegal for anyone to sell you a Medigap policy if they know you have Advantage. You must choose one path. Medigap works only with Original Medicare.

Is Medigap or Medicare Advantage cheaper?+

Medicare Advantage usually has lower or $0 monthly premiums, while Medigap has higher premiums but lower costs when you need care. Which is cheaper overall depends on how much healthcare you use. Heavy healthcare users often spend less with Medigap. Call 1-800-MEDIGAP to compare.

Can I switch from Medicare Advantage to Medigap?+

Yes, but outside guaranteed-issue situations you may face medical underwriting and could be charged more or denied for health reasons. The best time to choose Medigap is during your initial open enrollment. Call 1-800-MEDIGAP to review your switching options and timing.

Does Medigap or Medicare Advantage cover dental and vision?+

Medicare Advantage often bundles dental, vision, and hearing extras; Medigap does not. Medigap focuses on covering Original Medicare's gaps. If you want those extras with Medigap, you'd add a separate dental or vision plan. Our agents can arrange that, call 1-800-MEDIGAP.

Which plan lets me keep my doctor?+

Medigap lets you see any doctor or hospital nationwide that accepts Original Medicare, with no networks. Medicare Advantage restricts you to its network and may not include your current providers. If keeping your doctors matters most, Medigap is usually the safer choice.
