Medigaps are health insurance policies that offer standardized benefits to work with Original Medicare. They don’t work with Medicare Advantage Plans. Medigaps are sold by private insurance companies. If you have a Medigap, it pays part or all of the costs after Original Medicare pays first. Medigaps may also cover health care costs that Medicare does not cover at all—for example, care when traveling abroad.

 

Choosing a Medigap

Insurance companies may offer up to 10 different Medigap policies to choose from: A, B, C, D, F, G, K, L, M, and N. Each lettered policy is standardized. This means that all policies labeled with the same letter have the same benefits. Companies may sell the same Medigap for different prices, even though they have the same coverage. Note: Massachusetts, Minnesota, and Wisconsin have different Medigap plans.

 

Listed below are things you should consider when choosing a Medigap plan. Make sure to review the Medigap chart on the next page for more information.

• Plan A offers the most basic coverage. It’s often the least expensive.
• Plans F, C, and G are the most comprehensive Medigaps. They generally cost the most.
• Plans F and C are only available if you were eligible for Medicare before January 1, 2020.
• Medigap plans are guaranteed renewable. That means that as long as you pay the premium, you can keep your plan. However, premiums may change yearly.
• Shop around. Different insurance companies charge different premiums for the exact same policy.
