Medicare Supplement Plans – The Basics

Medicare Supplement plans are a type of health insurance. Thus, there are some terms that you may find confusing. In this section, you will understand what every plan and carrier offers.

Insurance is Private: Medicare is a federal program. However, Medicare Supplement plans are only sold by private companies and not by the government. But Medicare regulates all Supplement plans. Every insurance carrier can decide the list of plans it will offer.

Eligibility: Medicare Supplement plan is only accessible by seniors with Original Medicare. However, if you have Part C or Medicare Advantage plans, then you cannot purchase any of the Supplement plans because of overlapping issues.

Standard Plans: All Supplement plans are standardized. It means that they offer the same basic benefits no matter where you purchase them. However, some carriers can offer you extra benefits. The available Supplement plans are the following: A to D, F to G, K to N. If you are planning to purchase Plan A, for instance, this plan will have the same benefits as Plan A being offered by other carriers. However, if you live in Minnesota, Massachusetts or Wisconsin, the standard plans are different from other parts of the country.

Regarding plans C and F, though, they are only available to current subscribers. They are no longer open to new registrants since January 2020. If you have these plans already, you can still renew them.


Medigap: Medicare Supplement is also known as Medigap. Some insurance companies are using either of the terms. Other carriers are using MSI instead of Supplement or Medigap.


Plan Types: One plan is available in different variants, like select, high-deductible, and innovative. Medicare designed these plans but insurance companies managed to offer these variants.

  • High Deductible: It is a type of plan with a lower monthly premium and a higher out-of-pocket spending cap.
  • Select Plans: If you have a Medicare plan, you can visit any doctor without a referral. However, the physician should accept Medicare. On the other hand, if you have a Select type of plan, you can visit a smaller network of pre-approved doctors and facilities. The premiums on this type of plan are lower than the regular policy.
  • Innovative: An innovative plan of a certain Medicare Supplement has higher premiums than the standard plan. But it includes extra benefits like vision and dental coverage.


Prescription Medicines: Unfortunately, Medicare Supplement plans do not include prescription medication. If you want a plan with drug coverage, you should add Medicare Part D to your Supplement plan.


Pricing Structures: Medicare Supplement Plans have three pricing structures. These structures will impact your policy costs. The insurance company that provides your plan will determine the structure based on state laws. These pricing structures would include:

  • Community Rated: This pricing structure means that the monthly premiums are the same for all individuals who live in a certain area, no matter their age. But gender, tobacco use, and other factors can still affect the overall cost of your plan.
  • Attained Age: If the plan is using an attained age pricing, it means that the age when you first sign up for at 65 will determine your plan’s cost. However, as you get older, the premium increases. In that case, as you get older, your premium also becomes more expensive.
  • Issue Age: The age when you first buy the policy will determine your plan’s cost. However, it does not increase every year.

If you do, then you can proceed to other steps that will help you find the right carrier that offers the perfect plan.


Are you Eligible? 

medicare supplement insuranceNot all seniors can take advantage of this plan. One of the main requirements is that you need to have active Original Medicare, which consists of Part A and B. Now if you have a traditional Medicare but you own a Medicare Advantage or Part C plan, then you cannot purchase a Medicare Supplement Insurance. You must drop the Part C before you can obtain one of the Medigap plans. Seniors would purchase an Medicare Supplement plan if they want to add coverage to their health plans. With additional coverage, you can protect your finances from unexpected healthcare expenses. Indeed, you will have to pay for an additional monthly premium. Any Supplement plan will cover your copayments and deductibles.

It means lower out-of-pocket expenses should you need to undergo a medical service. Keep in mind that any medical expenses can easily strain your finances, especially if you did not plan for them. With a Supplement plan, you can have peace of mind knowing that most of your out-of-pocket expenses left by Original Medicare are covered.


Which Medigap Plan is Best for You?

After determining if you need an Medigap plan, the next step you must take is to evaluate your medical needs. In that way, you can find the right to cover those needs. You should also evaluate your financial situation before you decide on the kind of plan to sign up for. If you are in good health, you don’t need extensive coverage. In that case, plans A, K or L might be the most suitable option. These plans offer basic coverage and the monthly premiums are the lowest compared to Plans C, G, and F.  You may visit Medicare’s official website to help you better understand what each Medicare supplement plan in 2021 covers. If you wish to obtain lower monthly premiums, you may consider Select versions. They are Supplement plans that let you choose providers from a pre-approved list.


What other Services are Available in 2021?

Additional services may not affect your decisions. However, they are worth considering. For instance, if you are taking a lot of prescription medicines, then having a Part D plan can be useful as it can take care of your medications. Furthermore, you may consider purchasing a Medigap plan from an insurance provider that offers hearing, dental and vision insurance options. In that way, there is no need for you to go to another carrier just to purchase such coverage. Some insurance providers may provide member benefits. These benefits will depend on the company that offers them. For example, an insurance carrier offers wellness products and gym memberships when you sign up for one of its MSI plans. Other insurance carriers include wellness coaching and telehealth that lets you talk to a nurse for medical advice.

These member benefits are not essentials. However, they make your plan more valuable.


Compare Medicare Supplement Rates

After knowing what your coverage needs are, you can now start comparing one company to another. To do that, you need to obtain quotes. We recommend requesting quotes from three different providers before you make a final decision. You can request quotes online.

However, if you want to verify some things, you need to consider calling the provider’s agents. Calling their customer support team will also help you assess whether or not it is responsive. How the team answers your inquiries can also help you resolve whether you want to work with those people.

As you compare quotes, you may also look for discounts. Keep in mind that some providers don’t promote their discounts. The reason for this is that they only give discounts to those eligible people. For instance, you may be qualified to get a discount from your plan if another person in your household is getting coverage through the same company.

You may also get discounts if you don’t smoke or choose to have automatic payments. And if you choose to pay your premiums for the entire year, then discounts may also be given. You should also assess the services of the company. For instance, does it have local agents to process your requests or does the company have an online portal where you can view your policy information or make payments?

It is also ideal that you evaluate the company’s website and assess whether it is comfortable to use it. Keep in mind that if you choose such a company, you will be using its website more often when tracking your claims or paying your premiums.

Don’t Miss Open Enrollment

Once you have chosen the plan that can give you adequate coverage, you should only sign up for it during your open ennoblement period. This period starts three months before your 65th birthday. If you missed it, you will have another three months after the said birthday. You must sign up during open enrollment to get a low cost on the plan. Furthermore, no insurance provider can deny you coverage because of your pre-existing medical condition.


Understanding Medicare Supplement Plans in 2021

Medicare Supplement plans are regulated. It means that the carriers offering them must follow the federal and state laws. The laws are provided to protect consumers. And one way to do that is to offer each plan the same basic benefits no matter where you purchase the plan. Although each plan will have the same coverage, carriers can provide additional perks. They allow you to pick a plan that meets your individual coverage needs.

Insurance carriers can decide what Supplement plans to offer. However, the carriers must follow the state laws, which will affect the list of plans being offered in your area. Indeed, insurance providers are not mandated to offer all 10 Supplement plans. However, they are required to offer Plan A.

No insurance providers can deny you coverage for your pre-existing condition. They also can’t charge you more because of your medical disease.


That’s why you must take advantage of this period to get lower monthly premiums and guaranteed approval. If you purchase a Medicare supplement plan after this period, you will face higher monthly premiums and your coverage might be denied.

It varies depending on your location. But the overall cost will also depend on the coverage level, age, gender and whether or not you use tobacco. Of course, if you are a smoker, your monthly premium will be higher than the premiums of individuals who don’t smoke.

That’s why many seniors, even though they are healthy, are getting more coverage.
