Original Medicare covers a lot – but it leaves real gaps: deductibles, 20% coinsurance with no annual cap, and more. Medicare Supplement insurance, better known as Medigap, exists to fill those gaps.
How Medigap Works
Medigap policies are sold by private insurers and work alongside Original Medicare. Medicare pays first; your Medigap plan picks up some or all of the remainder, depending on the standardized plan letter you choose (Plan G and Plan N are today’s most popular).
What Medigap Gives You
Predictable costs, freedom to see any doctor in the country who accepts Medicare, no referrals, and nationwide coverage that travels with you. For many retirees, that certainty is worth the monthly premium.
When to Enroll
Your 6-month Medigap Open Enrollment Period starts when you are 65+ and enrolled in Part B. During this window, insurers cannot deny you or charge more due to health conditions. Miss it, and medical underwriting may apply.
Medigap or Medicare Advantage?
You cannot have both. Medigap pairs with Original Medicare for maximum flexibility; Medicare Advantage bundles coverage with extras at lower premiums. The right answer depends on your health, budget, travel habits, and provider preferences – exactly what a licensed agent can help you weigh.
Frequently Asked Questions
Does Medigap cover prescription drugs?
No. Modern Medigap plans do not include drug coverage – pair your plan with a standalone Part D plan.
Can I keep my Medigap plan if I move states?
Yes. Medigap coverage travels with you anywhere in the U.S. that accepts Medicare.
