What Are Medicare Supplement (Medigap) Plans?

Medigap plans help cover some of the gaps in Original Medicare. Each plan provides more financial coverage by paying various deductibles, coinsurance, and copayments. Plans do not provide additional benefits, like coverage for prescription drugs or the government Flex Card for Seniors. Those are covered under a separate Medicare Part D plan or with a Medicare Advantage Plan.

Types of Plans

In all but three states, there are 10 types of Medicare Supplement Plans available. Each standardized plan has a letter designation (A through N) and provides different levels of coverage for copays, coinsurance, and deductibles for Original Medicare Parts A and B. Massachusetts, Minnesota, and Wisconsin have their own plans that do not follow Medicare's standardized letter plans. Medigap plans are standardized by Medicare to include the same basic benefits regardless of where the policy is purchased. This makes comparison shopping easier. Choose the coverage you need and compare prices. Also See: 3 Most Popular Medicare Supplement Plans for 2023

What Are The Benefits?

Medigap plans cover costs that traditional Medicare doesn’t cover such as copayments and deductibles. They provide additional financial coverage, not extra healthcare benefits. The primary benefit of supplemental coverage is financial protection. Finding the best Medigap plan is all about balancing your healthcare needs with your finances. The Medigap plan that's best for you is a personal choice. All Medicare supplemental plans cover some of the following costs: Additional Information: What are the Disadvantages of a Medigap Plan?

Medicare Supplement Plans Comparison Chart

There are 10 standardized Medigap plans identified by the letters A through N. Plans with the same letter have the same basic benefits regardless of the carrier selling the plan. For instance, all Plan G policies provide the same benefits. However, monthly premiums will vary based on the way each carrier sets its rates (e.g., attained-age-rated, community-rated, or entry age-rated). The following comparison chart shows what each lettered plan covers: Medicare Supplement Plans Comparison Chart for 2024

How Much Do Medicare Supplements Cost?

Medigap plans are standardized, but policy prices are set by the individual insurance companies selling them. Companies set their monthly premium rates in one of three ways:
  1. Attained-age-rated: Monthly premiums are based on age at the time of purchase. Premiums increase as you age.
  2. Community-rated: Monthly premiums are the same for everyone in the policy, regardless of age.
  3. Issue or entry age-rated: Monthly premiums are lower if you purchase the policy at a younger age. Rates do not increase with age.
The attained-age rating method is the most common method used.

Medigap Plans F, G, and N: Which Plan Is Best?

Medicare Supplement Plans F, G, and N are the most popular Medigap plans sold, but are they the best? Not necessarily. When considering which Medicare Supplement Plan is best for you, it’s important to identify your current and future healthcare needs. This is the only way you can determine if a particular supplement is a better plan option for you.

Plan F

Medigap Plan F offers the most comprehensive coverage allowed by Medicare. It covers all deductibles, coinsurance, and copayments in Original Medicare. With this plan, you have first-dollar coverage. Unfortunately, this plan is only available to individuals who qualified for Medicare prior to January 1, 2020. Opting for the most comprehensive plan can provide assurance and peace of mind. However, this plan's cost is significantly more than basic plans. Select the plan that strikes the best balance between one’s specific healthcare needs and budget. Related: Medicare Plan F vs Plan G: Which is Better in 2023?

Plan G

If you want or need comprehensive coverage, but you don't qualify for Plan F, then Plan G is what you want. Plan G covers all Original Medicare costs except the Part B deductible ($240). And, in most cases, it's actually more affordable than Plan F when you factor in the deductible. Also See: 9 Medicare Plan G Pros and Cons You Can’t Ignore

Plan N

If you are a healthy individual, Plan N might offer the best balance of coverage vs. cost. It covers all of the big costs, just like F and G, but it leaves you with some minor Part B costs. The reason Plan N supplemental insurance plans work so well for healthy people is that they don't use a lot of medical services. As a result, the monthly premiums are 20% to 30% lower than Plan G. Even though this plan does not cover Part B excess charges, there's a small copay for doctor office visits and emergency room visits, healthy people save money. When comparing the benefits of this plan, remember that Medicare covers 100% of your annual wellness visits and preventive care costs, like vaccinations.

Other Medigap Plans

When budget is as much a consideration as coverage, look at Plan K and High Deductible Plan G. Both of these Medicare plans have low premiums, starting around $40 to $50 per month, but they work very differently. Plan K is one of two plans with an annual out-of-pocket limit. When you reach the annual limit, the policy begins paying all covered costs. The 2024 Plan K limit is $7,060. Until you reach the out-of-pocket limit, Plan K pays 50% of your costs. However, it does not cover the Part B deductible or excess charges. And, it does not include coverage for foreign travel emergencies. Plan K can save you money if you are in reasonably good health. Even though it does not cover 100% of the big costs right away, it's there if you have an extended hospital stay. For More Information: How Does the Plan K Medicare Supplement Work? Like Plan K, High Deductible Plan G (HDG) has an annual out-of-pocket limit, of sorts. It's the annual deductible ($2,800 in 2024). However, unlike Plan K, HDG doesn't pay anything until your out-of-pocket expenses reach the full deductible. Then it pays all costs until the end of the year. Also See: 9 Facts About High Deductible Plan G and How it Works

What Healthcare Providers Are Covered?

Generally, Medicare Supplement Plans cover all providers that accept Medicare, so long as the provider is accepting new patients. However, some plans offer plans with more limited coverage and may require you to obtain healthcare services from a specific network of providers affiliated with their plan. These are called Medicare SELECT plans. For some individuals, having a Medicare SELECT plan with a designated provider network makes sense as these plans cost less. Having a more restrictive plan can also provide cost savings for certain services due to potential discounts associated with the network.

Who Is Eligible for Supplemental Medicare Insurance?

Eligibility for a Medicare Supplement Plan is determined by several factors. While all plans are available to those who qualify for Medicare Part A and Medicare Part B at age 65, eligibility after your initial enrollment period may be limited based on existing health conditions or by the state of residence. Also See: Why Can You be Denied a Medicare Supplement Plan? If you have a Medicare Advantage plan, you are not eligible for a Medicare Supplement without first switching back to Original Medicare. And, if you are under age 65 and have Medicare due to a disability, be aware that Medicare does not guarantee coverage, but a few states do. Keep in mind that availability, cost, and protections differ from state to state. Consult with a licensed insurance agent about your state's regulations prior to making any decisions. For More Information: Medicare Supplement (Medigap) Plans: Coverage, Costs, and Eligibility

Your Medigap Protections

By federal law, everyone is entitled to get Medicate Supplement Plan coverage at age 65 during their Medigap open enrollment period. Your open enrollment period starts the first month you sign up for Medicare Part B at age 65 or older and ends six months later. This includes individuals who delayed Medicare enrollment because they had creditable coverage through their employer. During your Medigap open enrollment period, your choice of Medicare supplemental insurance is wide open. There is no medical underwriting process to go through. You can choose any plan you want from any insurance company you choose in your area. Your policy cannot be canceled by the insurance company even if your health status changes. So long as you pay your premiums, your policy will continue to renew. If you’re already enrolled in a Medigap plan, you may apply to switch plans. However, once your open enrollment period is over, you no longer have guaranteed issue rights and your application can be turned down Companies may also delay coverage for up to six months for a pre-existing condition if you didn’t have creditable coverage before signing up for Medicare.

How To Enroll In A Medicare Supplement Plan

Enrolling in a Medigap plan is easy. Medicare Supplements may be purchased through an insurance agent, an agency, or directly through the insurance carrier. And, because there’s no annual open enrollment period, you can enroll at any time. The best time to get a Medigap policy is during your Medigap Open Enrollment period. During this 6-month period, you can buy any Medigap plan sold in your state, even if you have pre-existing health conditions. Follow these four steps:
  1. Enroll in Medicare Part A and Part B. You cannot begin applying for Medigap until you have completed this step. If you’re enrolled in a Medicare Advantage plan, you will need to drop your plan before buying a Medigap plan.
  2. Find which insurance companies in your state sell Medigap plans by using our finder tool or Medicare.gov.
  3. Compare costs between companies. Costs will vary depending on the company, state, age, gender, and use of tobacco.
  4. Select the plan that works best for you and purchase your policy.

What Are The Alternatives?

While a Medicare Supplement Plan can be beneficial, there are alternatives that may be more affordable, including:

Medicare Advantage Plans

Those looking for more healthcare benefits with an annual limit on out-of-pocket costs should compare Medicare Advantage Plans in their area. Many Medicare Advantage Plans cover prescriptions, routine dental care, vision, hearing aids, and transportation services, just to name a few. For More Information: Top Medicare Supplement vs Medicare Advantage Pros and Cons When looking at Medigap vs. Medicare Advantage Plans, take into account HMO and PPO provider restrictions. If you use certain providers regularly, you will want to make sure they are in the network for the plan you choose and verify whether their services are covered under the plan’s terms and conditions. Pay close attention to deductibles, copayments, and coinsurance associated with the healthcare service you use most. These costs are often higher in Medicare Advantage Plans than in Original Medicare. Make sure to consider travel, as well. Medigap policies cover you throughout the United States, whereas Medicare Advantage plans do not (except in emergencies). And, many Medigap plans cover foreign travel emergencies, whereas Medicare Advantage Plans don't.

Medicare Savings Accounts

Another alternative is a high-deductible health plan (HDHP) with a Medicare Savings Account (MSA) plan. With an MSA, any money saved from the high deductible can be used in the case of medical emergencies or catastrophic events. Though this type of plan requires more out-of-pocket spending than a Medigap plan, it is typically less expensive. Each year the beneficiary receives an initial lump sum payment. Deductibles and out-of-pocket maximums should be heavily considered before making a decision to go with an MSA.

Medicare Special Needs Plans

Special Needs Plans, or SNPs, are Medicare Advantage Plans specially tailored for three different needs:
  1. Dual-eligible (Medicare and Medicaid) individuals
  2. People with certain chronic illnesses
  3. Institutionalized and home-bound individuals
We organize these plans in their own directory. You can compare Special Needs Plans in your area with our SNP finder tool.

Medicaid and Medicare Savings Programs

Those who qualify for both Medicare and Medicaid may not require or be eligible for supplemental coverage. Dually eligible individuals generally have limited out-of-pocket expenses. This includes prescription medication costs, which are largely covered by the Extra Help program. Dual-eligible individuals may also want to consider a dual-eligible Special Needs Plan (D-SNP). These are Medicare Advantage Plans designed specifically for people with both Medicare and Medicaid benefits. D-SNP plans are available in most locations.

Veteran Healthcare

If you are a veteran (thank you!) and have VA health benefits, you may be able to use the VA to help cover costs not covered by Medicare. As a veteran with both VA and Medicare healthcare benefits, Medicare is the primary payer and the VA is secondary. If you use a VA hospital or get pre-approval for VA Community Care, Medicare pays its share and the VA pays the remainder. Depending on your VA status, you may or may not be required to pay a copayment. It is important to note that no Medicare plan options cover long-term care, in-home assistance, or adult daycare. Depending on the person’s needs, long-term care insurance can provide all or part of the cost of these types of care.

What To Consider Before Choosing a Plan

When choosing a Medicare Supplement, it is important to consider the following factors:
  1. Cost – Consider the monthly cost of a Medigap plan in comparison to how much coverage you’ll receive for your money. Don’t forget to factor in additional coverage such as prescription drugs and vision or dental care.
  2. Coverage – Your plan should provide the coverage that best meets your needs. Look closely at the costs covered and excluded by various plans.
  3. Nation-wide acceptance – Verify that the plan you are selecting is accepted by doctors and hospitals nationwide, not just within your hometown.
  4. Quality of customer service – Investigate the reputation of any company you are considering for their customer service ratings and reviews from other customers.
  5. Cost sharing – Most Medicare Supplement Plans require some sort of cost sharing for services received. Be sure you know what your financial obligations will be when accessing healthcare services.
  6. Financial strength and experience – A Medigap policy is a financial instrument. Getting a policy from the lowest-cost insurer may work out initially, but what if they go out of business?
  7. Rate increase history – Depending on the insurer, Medigap policies tend to increase between 4% and 9% per year. It's important to get the Medigap rate increase history on the carriers you're considering.
Be aware that some Medicare Supplement Plans, called Medicare SELECT Plans, also have provider restrictions. These plans generally require their beneficiaries to use a local hospital for most of their healthcare services.

However, the one cost that Plan G does not cover, the Part B deductible, is often less than the annualized premium difference between the two plans.
