Plans offering more coverage can sometimes be more expensive than plans with more basic coverage. 

Who are the Carriers for Medigap?

Medicare Supplement Insurance is sold by private insurance companies that set their own plan prices. In the same way that the same pair of shoes can cost much different in one store compared to another, the same Medigap plan can cost a different amount between two insurance companies. 

Location

The cost of living can be significantly different in one market compared to another. It’s not uncommon for a product to cost more in a large city than it does in a more rural setting, and the same can be said for Medicare Supplement Insurance plans.

You may also find that areas with more plan options may have lower costs because of the increased competition. 

Enrollment Time

If you apply for a Medicare Supplement Insurance plan during your Medigap Open Enrollment Period, you will have guaranteed issue rights. That means an insurance company is not allowed to use medical underwriting to charge you a higher rate for your coverage.

However, if you enroll outside of this period or during any other time during which you don't have a guaranteed issue right, you are no longer protected and carriers may charge you a higher rate because of your health.

Other reasons you might be eligible for guaranteed issue rights include if you move to an area that isn't served by your previous plan, if your insurance company stops offering your plan or if you otherwise lose coverage through no fault of your own.

What is the Pricing Structure for Medigap?

Medicare Supplement Insurance companies typically price their plans in one of three ways according to age.

  • They might charge everyone the same rate regardless of age. This is called a community rated plan.

  • They might base your rate on the age at which you joined the plan. This is called an issue-age rated plan.

  • Some plans might increase your rate for every year that you age while enrolled in the plan. This is called an attained-age rated plan.

Are There Discounts for Medicare Supplement Plans?

It’s not uncommon for insurance companies to offer discounts on Medicare Supplement Insurance plans. Discounts are often available for non-smokers, married couples and other criteria. Be sure to ask your insurance agent or insurance carrier about any potential discounts that may be available.

Gender

Because women have a longer life expectancy, they are sometimes granted lower premiums for Medicare Supplement Insurance plans.  

Additional Costs for Supplemental Insurance

There are some additional things to know about the costs associated with a Medicare Supplement Insurance plan. 

  • Two plans, Plan F and Plan G, have a high-deductible option available in some areas. The high-deductible version of these plans has a lower monthly premium than the standard version in exchange for a deductible. The plan’s coverage does not begin until the deductible has been satisfied. The deductible for these plans in 2024 is $2,800 for the year.

  • Two plans, Plan K and Plan L, feature an annual out-of-pocket limit. Once the beneficiary has reached the out-of-pocket limit for covered services, the plan pays 100% of the cost of covered care for the remainder of the year. The 2024 out-of-pocket limits are $7,060 for Plan K and $3,530 for Plan L. 

  • While Plan N covers 100% of the cost of the Medicare Part B coinsurance, the plan requires a copayment of up to $20 for certain office visits and up to $50 for emergency room visits that do not result in an inpatient admission.
