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 2020?

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. In 2017, 55 percent of all Medigap beneficiaries were 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 31 percent between 2016 to 2017.2

    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 2020 Part B deductible is $198 per year ($16.50 per month).

    This means that if you find a Medigap Plan G option that costs only $16.50 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).

That means the benefits of Ohio Medigap Plan A will be exactly the same as Texas Medigap Plan A.

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 $1,408 per benefit period in 2020).

    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 $352 per day through day 90.

    After your 90th day in the hospital, you must pay $704 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 $1,408 per benefit period in 2020.

    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 2020, the Part B deductible is $198 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 $176 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.

  • 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 Happens to Plan C and Plan F in 2020?

Medigap Plan F and Plan C will not be available to anyone who becomes eligible for Medicare on or after January 1, 2020.

Plan F and Plan C are not ending, however. If you already have Plan C or Plan F before 2020, you will be able to keep your plan.

If you become 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 $2,340 in 2020.

You must meet this $2,340 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

Plan K and Plan L each have an annual out-of-pocket spending limit.

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 $5,880 in 2020. The 2020 Plan L out-of-pocket spending limit is $2,940.
