What Is Medigap Insurance?
Medicare Supplement plans (commonly referred to as Medigap) are insurance plans that work alongside your Medicare Part A and Part B benefits and help cover some of your Medicare deductibles, coinsurance, copays and other costs.
Here are some key facts about Medicare Supplement Insurance:
- Medigap insurance doesn't typically offer any additional benefits. Instead, it picks up the out-of-pocket costs associated with Medicare.
- Medigap insurance is accepted by any doctor, hospital or health care provider who accepts Medicare.
- If your health care service or medical device is covered by Medicare, your Medigap plan would cover any additional out of pocket costs so that you don't pay anything for your services (depending on your Medigap plan coverage and whether or not you've reached certain Medicare deductibles).
What Are the Costs for Medicare Supplement Plans?
Medicare Supplement Insurance plan premiums are sold by private insurance companies. This means that plan availability and plan premiums may vary.
The average premium cost for a Medicare Supplement Insurance plan in 2018 was $152 per month.1
The average cost of each type of Medigap plan can vary quite a bit from one plan type to another. Each type of Medigap plan offers a different combination of standardized benefits, which means that plans with fewer benefits may offer lower premiums.
Your age, gender, smoking status, health and the location where you live can all also affect the average cost of Medigap plans near you.
What Is the Best Medicare Supplement Insurance Plan in 2021?
There isn't one “best” Medigap plan. A specific Medigap plan might work for you if it offers coverage that works for your needs and comes with premiums that fit your budget.
Medigap Plan F is the most popular Medicare Supplement Insurance plan. 53 percent of all Medigap beneficiaries are enrolled in Plan F.2
Plan F covers more standardized out-of-pocket Medicare costs than any other Medigap plan. In fact, Plan F covers all 9 of the standardized Medigap benefits a plan may offer.
The average Plan F premium in 2018 was $169.14 per month.1
Medigap Plan G is the second most popular Medigap plan, and it is quickly growing in popularity. Plan G enrollment spiked 39 percent in recent years.2
Medigap Plan G covers all of the same out-of-pocket Medicare costs than Plan F covers, except for the Medicare Part B deductible. The 2021 Part B deductible is $203 per year ($16.92 per month).
This means that if you find a Medigap Plan G option that costs only $16.92 more per month (or less) than Plan F, it might be a better value over the course of the year than Plan F if you meet the Part B deductible.
The average Medigap Plan G premium in 2018 was $122.78 per month.1
Your unique health coverage needs and budget are important factors to consider as you shop for Medicare Supplement Insurance plans.
The potential cost predictability a Medigap plan can bring may be able to help you better predict your monthly health care spending.
You can combine a Medigap plan with a Medicare Part D prescription drug plan, which can help cover your costs for retail prescription drugs.

Do All Medicare Supplement Insurance Plans Pay the Same?
The cost of a Medicare Supplement Insurance plan can vary from one carrier or location to the next.
However, the standardized benefits that each type of Medigap plan covers stays the same, no matter where you live or who your plan carrier may be (except for in Massachusetts, Minnesota and Wisconsin, where Medigap plans have different standards).
The 9 standardized benefits that may be offered by a Medicare Supplement Insurance plan include the following:
Medicare Part A coinsurance and hospital costs
Medicare Part A helps cover your hospital costs if you are admitted to a hospital for inpatient treatment (after you reach your Medicare Part A deductible, which is $1,484 per benefit period in 2021).
For the first 60 days of your hospital stay, you aren't required to pay any Part A coinsurance.
But beginning on day 61 of your stay, you're required to pay Medicare Part A coinsurance, which is $371 per day through day 90.
After your 90th day in the hospital, you must pay $742 per day for up to 60 more days. Beyond that, you are responsible for all hospital costs.
Medicare Part A deductible
Before your Part A coverage kicks in, you are required to pay the Part A deductible of $1,484 per benefit period in 2021.
The Medicare Part A deductible isn't an annual deductible. This means that you could potentially have to meet the Part A deductible more than once in a given year.
Medicare Part B deductible
Before Medicare Part B covers any of your costs for things like doctor's appointments or medical devices, you must meet your Part B deductible.
In 2021, the Part B deductible is $203 per year.
Medicare Part B coinsurance or copayment
After you meet your Part B deductible, you are typically required to pay a coinsurance or copay of 20 percent of the Medicare-approved amount for your covered services.
There is no limit to how much you may be required to pay for this 20 percent copayment or coinsurance in a given year, if you do not have a Medigap plan that provides coverage for this cost.
Medicare Part A hospice care coinsurance or copayments
If you receive hospice care that is covered by Medicare, you are required to pay a Part A copayment for prescription drugs you use during hospice. You may also be charged 5 percent coinsurance for inpatient respite care costs.
Coinsurance for skilled nursing facility
There is no coinsurance requirement for the first 20 days of inpatient skilled nursing facility care.
However, a $185.50 per day coinsurance requirement begins on day 21 of your stay, and you are then responsible for all costs after day 101 of inpatient skilled nursing facility care (in 2021).
Medicare Part B excess charges
Excess charges can be accrued when you receive Medicare-covered services or items from a provider who does not accept Medicare assignment. This means that they don't accept Medicare reimbursement as payment in full for their services.
In such a case, the provider reserves the right to charge you up to 15 percent more than the Medicare-approved amount.
First three pints of blood
Original Medicare does not provide coverage for the first three pints of blood that are used in a blood transfusion.
Foreign travel emergency care
Medicare does not typically provide coverage for emergency care received outside of the U.S. or U.S. territories.
What Happened to Plan C and Plan F in 2020?
Medigap Plan F and Plan C are not available to anyone who became eligible for Medicare on or after January 1, 2020.
If you already had Plan C or Plan F before 2020, you will be able to keep your plan.
If you became eligible for Medicare before 2020, you may still be able to buy either Plan C or Plan F after January 1, 2020, if either is available where you live.
What Are High Deductible Plans F and G?
Plan F and Plan G both offer high deductible options, which carry a deductible of $2,370 in 2021.
You must meet this $2,370 plan deductible before your plan coverage kicks in for the rest of the plan year. One tradeoff for the high deductible is a lower monthly premium.
The average premium for a standard Plan F in 2018 was $169.14 per month, while the average premium for high-deductible Plan F was just $57.16 per month.1
Medigap Plan K and Plan L Have Annual Out-of-Pocket Spending Limits
Once you reach this limit within a calendar year, the plan will pay 100 percent of the costs for your covered Medicare services for the remainder of the year.
The Plan K out-of-pocket maximum is $6,220 in 2021. The 2021 Plan L out-of-pocket spending limit is $3,110.
