The average premium a Medicare Supplement Insurance (Medigap) plan beneficiary paid in 2018 was $125.93.1 But the average cost of each type of Medigap plan can vary quite a bit from one plan type to another.
It’s important to note that each type of Medigap plan offers a different combination of standardized benefits. Plans with fewer benefits may offer lower premiums.
Other factors such as age, gender, smoking status, health and where you live can also affect Medigap plan rates.
The chart below shows the average monthly premium for each type of Medicare Supplement Insurance plan sold nationwide in 2018.1
The average Medigap premium cost across all plans in 2018 was $152 per month, but some types of Medigap plans have far fewer enrollees than other types of plans. This difference in enrollment affects the average monthly premium that is actually paid by Medigap beneficiaries.
That's why the weighted average Medigap plan premium paid by a beneficiary in 2018 was $125.93 per month.
(Data excludes Plan K and Plan L, which have a combined enrollment of fewer than 1.5% of all Medigap beneficiaries as of 2016).2
|Medicare Supplement Insurance Plan||Average monthly premium|
|High deductible F||$57.16|
* Medigap Plan J was discontinued for new enrollees in 2010. Only beneficiaries who enrolled in the plan prior to that time may be currently enrolled in Plan J.
There are several factors that affect the price of a Medigap plan, such as the plan benefits, the Medicare Supplement Insurance company selling the plan, the company’s age-related pricing system and when you buy your Medigap plan.
While there are certainly exceptions to the rule, Medigap plans with more benefits will typically cost more than plans offering fewer benefits.
There are nine potential benefits that can be covered by the 10 standardized Medicare Supplement Insurance plans sold in most states (Massachusetts, Minnesota, and Wisconsin have different standards). Each type of plan offers partial or full coverage for a different combination of these benefits.
You can use the chart below to compare the benefits offered by each type of standardized Medigap plan.

Medicare Supplement Insurance plans are sold by private insurance companies who are free to set their own prices.
Medigap Plan C sold by one carrier might cost slightly more or less than Plan C sold by another carrier, though the two plans offer the same benefits.
Where you live plays a part in determining the price of Medicare Supplement Insurance plans available to you. In the same way that a gallon of milk might cost more in one city than another, so too can a Medigap plan.
In fact, the average cost of Medigap Plan F in New York was $334.92 per month in 2018. The average cost for Medigap Plan F in Iowa was $141.04 per month in 2018.1
There are three different age-related pricing models that Medicare Supplement Insurance companies use to determine their Medigap plan rates. Each type of cost model can affect the average price of a given plan.
Medigap premiums can increase over time due to inflation and other factors, regardless of the pricing model your insurance company uses.
Depending on when you sign up for a Medicare Supplement Insurance plan, you may be subject to medical underwriting.
Underwriting is the process by which an insurance company assesses your current health and your health history to determine your Medigap plan costs. If you are in poor health, the insurance company may deem you to be a higher risk, and they may charge you more for your Medigap plan. If your health history is too high risk for the insurance company, they may choose to deny you coverage.
If you enroll during your Medigap Open Enrollment Period (OEP), Medicare Supplement Insurance companies cannot use medical underwriting to determine your plan costs.
Your Medigap Open Enrollment Period is a six-month period that begins when you are at least 65 and enrolled in Medicare Part B. If you enroll in a Medigap plan after your Medigap Open Enrollment Period, insurance companies reserve the right to utilize medical underwriting to determine your plan premium or if they will offer you coverage at all.
The ability to enroll in a Medigap plan without medical underwriting is called a Medigap guaranteed issue right. In addition to your Medigap OEP, there are several Medigap guaranteed issue rights that allow you to sign up for a Medigap plan without medical underwriting.
Some Medigap insurance companies may offer discounts to women, non-smokers, married couples and for other reasons.
Be sure to ask a licensed insurance agent about any possible discounts that may be available for Medigap plans available near you.

Depending on the average cost of Medicare Supplement Insurance plans in your area, you may wonder if the benefits are worth the premium costs.
When deciding whether or not to enroll in a Medigap plan, consider some of the potential costs that you may face without the protection of a Medigap plan.
Health care costs can be unpredictable and unexpected. Having a Medicare Supplement Insurance plan can make your health care spending more predictable, which can help you better budget for your care.
You can enroll in a Medigap plan or change Medigap plans at any time of the year. However, you may be subject to medical underwriting as part of the application process.
The best time to buy a Medigap plan, however, is during your Medigap Open Enrollment period or during another time when you have a Medigap guaranteed issue right. This can help protect you from potentially paying higher Medicare Supplement Insurance costs due to your health.
A licensed insurance agent can help you compare the average cost of Medicare Supplement Insurance plans in your area and find a plan that works for you.
