Medicare Supplement Insurance (Medigap) Costs

Key Takeaways:

  • When Original Medicare (Parts A and B) doesn’t cover all healthcare costs, Medicare Supplement Insurance (Medigap) plans are available to help cover cost gaps in coverage.

  • Offered by private health insurance companies, approved by Medicare.

  • Medicare supplement costs have different rate structures called “ratings.”

    What is Medicare Supplement Insurance (Medigap)?

    Original Medicare (Parts A and B) covers the majority of your healthcare needs, but it’s not intended to cover everything. If you rely on Original Medicare alone, you risk “gaps,” which may lead to significant expenses from medical treatments and extended hospital stays.

    Supplement Insurance (Medigap) is health insurance sold by private companies to cover costs in these gaps.

    Also known as letter plans, Medigap policies range from essential coverage, Plan A, and increases alphabetically to the most comprehensive Plan J (although this plan is no longer available to new beneficiaries). Plans K and L also cover a portion of the Part A and B deductibles . In contrast, Plan N focuses on Plan A deductibles. For more information on each plan, check out our Medigap coverage guide.

    It’s important to know that all Medigap policies are standardized  by the federal government, which means each plan must be the same in each state. For example, a Plan “A” policy sold by “Company 1” must provide the same coverage as the Plan “A” policy sold by “Company 2.”

    Aside from which plans are available in your state, one of the things you’ll want to figure out before buying Medigap is how the insurance company calculates its rates. We put together a breakdown to help answer, “How much does Medicare supplemental insurance cost?”


How Much Does Medigap Cost?

To be eligible for a Medigap plan, first, you must be enrolled in Original Medicare (Parts A and B). When you combine Medicare Part A and Medicare Part B with a Medigap plan, you pay a monthly premium for Medigap, as well as any Original Medicare premiums.


How is the cost of a Medicare supplement policy determined?

Insurance companies use one of three formulas, or rating systems, to determine the supplemental insurance cost.



What is Medicare SELECT?

Some states offer a low-cost version of their Medigap plans, which is called Medicare SELECT. The low cost comes from the limited network of healthcare providers and hospitals that are covered. If you must receive care that’s out-of-network , you’ll be responsible for all the costs not included in your coverage.


Are There Any Hidden Costs?

Insurance companies and providers must give a clear description of Medigap costs, including coverage limitations . Your Medigap costs will be higher if you put off enrolling when you’re first eligible.

Your open enrollment period includes guaranteed issue rights, which means you cannot be denied coverage because of your medical history.

If you wait to sign up for Medigap after your OEP, you may not have the same rates or coverage levels.

How Do I Buy Medigap?
