What Is Medicare Supplement Insurance?

Medicare Supplement Insurance is a type of plan that is used in conjunction with Original Medicare (Medicare Part A and Part B). Medigap plans provide coverage for Original Medicare’s deductibles, copayments, coinsurance and other out-of-pocket requirements. 

There are 10 different standardized Medigap plans in most states, and each one is identified by a letter, including Plans A, B, C, D, F, G, K, L, M and N.

1. Plans C and F are not available to new beneficiaries who became eligible for Medicare on or after January 1, 2020.
2. Plans F and G also offer a high deductible plan which has an annual deductible of $2,370 in 2021. Once the annual deductible is met, the plan pays 100% of covered services for the rest of the year. The high deductible Plan F is not available to new beneficiaries who became eligible for Medicare on or after January 1, 2020.
3. Plan K has an out-of-pocket yearly limit of $6,220 in 2021. Plan L has an out-of-pocket yearly limit of $3,110 in 2021.
4. Plan N pays 100% of the Part B coinsurance, except for a copayment of up to $20 for some office visits and up to $50 for emergency room visits that don’t result in an inpatient admission.

Each plan’s benefits are standardized by the federal government, which means that every Medicare Supplement Plan A will include the same benefits, no matter where the plan is sold or by which insurance company provides the plan.  

With the right Medicare Supplement plan, you can nearly eliminate your out-of-pocket spending for Medicare-covered services.

What Is the Most Popular Medicare Supplement Plan? 

The most popular Medicare Supplement plan in terms of enrollment is Plan F. Plan F provides the most comprehensive coverage and leaves beneficiaries with little to no out-of-pocket Medicare expenses for covered care. 

However, Plan F won’t be the most popular plan for long. Some recent legislation barred Medigap plans from covering the Medicare Part B annual deductible, which applies only to Plan F and Plan C. Anyone who first became eligible for Medicare prior to Jan. 1, 2020 has been grandfathered in and may still enroll in Plan F or Plan C. But anyone who became eligible for Medicare after that date is prohibited from enrolling in either plan. 

If you had Plan F or Plan C before 2020, you can still keep your plan. If you were first eligible for Medicare before 2020, you can still apply for either plan if they’re available where you live.

This change leaves Plan G as the Medicare Supplement plan that offers the most benefits for new Medicare enrollees. Plan G is poised to take over the largest share of Medigap enrollment in the coming years, quickly becoming the most popular Medigap plan.

How Is Medicare Supplement Insurance Priced?

There are a few variables that can affect the cost of a Medigap plan. 

Coverage

Plan F typically costs more than Plan A. That’s partly because Plan F is the most comprehensive plan offering the greatest amount of coverage, while Plan A is the most basic plan offering the least amount of coverage.

As with some other types of health insurance, the more benefits that are offered by the plan, the more you may expect to pay for it. 

Location

While the benefits of each type of plan are standardized, plan premiums are not standardized. Medigap Plan F in Oklahoma will most likely cost less than Plan F in New York. In the same way that a gallon of milk can cost more in one city than another, so too can the cost of the same type of Medigap plan. 

Insurance Company

Medicare Supplement Insurance is sold by private insurance companies and there may be several different companies all selling the same plan in the same city. Each carrier will set its own price with its competitors in mind. 

Discounts

It’s common for insurance companies to offer discounts for Medigap plans. Women and non-smokers are often charged less because of their longer life expectancy. Potential discounts may also be extended to married couples who each purchase a plan or to those who use a direct withdrawal to pay their premiums and other things. 

When You Enroll

If you apply for a plan during your Medigap Open Enrollment Period, you will have guaranteed issue rights. That means an insurance company may not use medical underwriting to determine your quotes, and you will be offered the same rate as all other new enrollees, regardless of your health.

Your Medigap Open Enrollment Period lasts for only six months and starts as soon as you are at least 65 years old and enrolled in Medicare Part B.

If you wait to apply for a plan after this period has ended (or if you decide to change plans), companies are allowed to use medical underwriting to base your plan premium on your health status. If your health is too poor, you may be denied coverage entirely.

You may also have guaranteed issue rights at other times, such as if you move to an area that isn’t serviced by your previous plan or if you lose coverage through no fault of your own.

Pricing Structure

There are three ways Medicare Supplement plans can be priced, or rated:

  • An insurance company might offer all new enrollees the same rate regardless of age and then increase the cost every year. This is called attained-age pricing.

  • The insurance company might instead base your premium on your age at the time of enrollment in the plan. This is called issue-age pricing.

  • Another way an insurance company might price a plan may even offer the same rate to everyone, regardless of age. This is called community-rated pricing.

All of these various pricing structures can factor into your quote. 

What Other Medigap Costs Should I Consider?

The monthly premium is an important thing to consider when comparing Medicare Supplement Insurance quotes. But the premium alone doesn’t tell the full picture of a plan’s cost. Be sure to consider the following factors when crunching your budget numbers. 

Deductibles

Two Medigap plans, Plan F and Plan G, offer a high-deductible version in addition to the standard version of the plan. The high-deductible option comes with a lower monthly premium but requires you to meet an annual deductible before the plan’s coverage will take effect.

Out-Of-Pocket Limit

Plan K and Plan L feature an out-of-pocket limit, which is the total amount of money you will have to pay out of pocket on covered care before the plan pays 100% of all covered care for the remainder of the year.  

Plan Use 

It’s important to consider your health insurance habits when comparing quotes.

For instance, certain plans provide coverage for emergency care received in foreign countries. If you plan on traveling outside the country a lot during retirement, these plans may carry more value than plans that do not offer such coverage. And some plans provide coverage when seeing doctors that do not accept Medicare assignment, which can be more valuable to beneficiaries who do not always visit the same health care providers.
