Like millions of older Americans, if you recently turned 65 or you’re about to, you’re probably planning on enrolling in Medicare. This health insurance program, which is funded by the United States government covers the costs that are associated with a long list of healthcare services.

If you’re younger than 65 and you have been diagnosed with a certain disability or illness, you may qualify for Medicare, too.

Medicare doesn’t cover the cost of everything, however. Medicare Supplement Insurance (Medigap) can help to pay for some of the out-of-pocket expenses that Original Medicare doesn’t pay for.

Medigap has to be purchased through private insurance companies, and there are several options to choose from. In this guide, we cover the top Medicare Supplement Insurance providers.

How Does Medicare Supplement Insurance Work?

Medicare is comprised of four separate and distinct parts. Part A and Part B are known as Original Medicare. Part A covers the cost of medical care that you’ll receive while admitted to the hospital, as well as any related services. Part B pays for the cost of outpatient medical care, like doctor appointments, and durable medical equipment.

While Original Medicare can be a real lifesaver, it doesn’t cover the cost of all of your medical expenses; it only covers up to 80 percent. You’ll need to pay the remaining 20 percent – and products and services that Medicare doesn’t cover – out of your own pocket. These costs can really add up, but that’s where supplemental insurance can come in really handy.

Also known as Medigap, these policies cover some of the expenses that Medicare Part A and Part B won’t cover. In most states, there are 10 Medicare Supplement policies, which cover different Original Medicare expenses.

These plans are sold by private insurers, and each company can determine what policies they want to sell, how much they want to charge, as well as other things, like additional perks they provide for policyholders.
