What are Medicare Supplement plans?

Medicare supplement plans, also known as Medigap plans, are insurance policies that cover out-of-pocket medical expenses that Original Medicare does not cover. The table below explains what different Medigap plans cover.

Medigap plansCoverage
Basic coverage (plans A - N)Plan A covers basic benefits, Plans B and M offer the basic benefits and some extra benefits, Plans D and G have the highest benefit coverage and plan N covers lower premiums and higher copayment.
Broad coverage (plans F,C)Are only available for old Medicare members and not new members. It also has broad coverage. Both plans cover 80% of the emergency care during the first two months of each trip outside the US, after a $250 deductible, for a lifetime maximum of $50,000. Plan F covers part B excess charge. A percentage of the charge is covered either 80% or 100%.
Lower premiums (plans K,L)Has the lowest premium coverage. Both plans cover the basic benefits, but only cover 50% (K) or 75% (L). They also cover the part B coinsurance, hospice cost share and the first 3 pints of blood for each year. Plan K covers $6940, and plan L covers $3470 out-of-pocket limit. It covers most that the other plans cover but not in it entirety.

What are the best supplemental plans for seniors?

We cannot choose the best supplemental plan for seniors for sure, this is because individual needs and preferences differ. However, there are common Medigap plans that are usually recommended for seniors due to their broad and comprehensive coverage. You should however note that the plan availability and benefits may vary depending on your location.

One supplemental plan that is often recommended to seniors is the Medigap Plan G. It is recognized as a top-rated plan for seniors because it fills the most gaps in the Original Medicare, including Part A and Part B deductibles, copayments, and coinsurances. The only out-of-pocket cost you will be paying when you apply for Medicare supplement Plan G is the Plan B deductible annual fee. With Plan G, your Medicare-approved expenses are covered.

Another supplement plan seniors should consider is Plan N. This plan covers the same benefits as Plan G, although you will be required to pay some copayments and coinsurances for doctor and emergency room visits. It also offers a lower premium than Plan G offers and can help save on monthly costs. The best supplemental plan for seniors depends on the senior’s needs, budget, and preferences.

How much do Medicare supplement plans cost?

The cost of Medicare supplemental plans is not definite and depends on certain factors such as age, gender, health status, state, and specific plans. An average Medicare supplement plan however costs $50 - $400. The best way to be sure of the cost of a Medigap plan that suits you is to talk to the insurance carrier you want to purchase the policy from.

The plan type of your Medigap determines the benefits you will be offered and the type of plan can cause the cost of Medigap plans to vary. Also, the age at which you enroll for the plan can affect the cost of the plan. Normally the cost of the plan increases as your age increases, but some carriers allow you to lock the cost of your plan when you enroll at a certain age.

Some states also allow insurance companies to use underwritings to determine the cost of your Medigap plan; your health status can sometimes play a role in the amount you pay for your premium. Although your health status will not be taken into consideration if you enrolled during the enrollment period, the enrollment period is during your 65th birthday and the six months that follow. Some carriers also offer discounts such as household or non-smoker discounts - this may impact the amount your Medigap plan costs.

Lastly, your gender may affect the cost of your plan and also the ratings of your plan may determine the cost of your plan. Some Medigap plans are community-rated while some are issue-age-rated. Community-rated means everyone pays the same amount while issue-age-rated plan cost is determined by the age you enrolled for the plan.

How to pick Medicare insurance suitable for you?

Choosing a Medicare insurance plan that best suits will involve several steps that will ensure that you are getting coverage at a price you can afford. Below are some steps that will be helpful.

  • Evaluate your needs. You need to know what your needs are; what will you like the plan to cover. Answering this will help you select the right Medigap plan for you.
  • Research the Medicare supplemental plans options you have. Each of the Plans covers different benefits and it is important that you choose the one that best suits your needs.
  • Compare the coverage options of each of these plans. coverage for services such as coinsurance, copayments, deductibles, and foreign travel emergencies should be compared before making a final decision.
  • Factor in the cost of the premium. You should try to balance coverage with the cost of the premium. A plan with broad coverage may have a high premium rate, you should compare the cost of the plan you have chosen from other insurance carriers.
  • Do a thorough search on the reputation of the carrier. the financial stability of the carrier is key and its ability to honor financial obligation.
  • Know the enrollment period. The typical period for enrollment is usually when you clock 65 and when you are enrolled in Medicare Plan B. You can not get rejected during this period.
  • Research your state regulations and seek advice when necessary. Most carriers have customer care representatives who can help you whenever the need arises.

Medicare Supplement vs. Medicare Advantage

Medicare Supplement also known as Medigap is different from Medicare Advantage also known as Part C - both are two different types of insurance options that work alongside Original Medicare(Part A and B). Medigap plans help to cover the gaps in the original Medicare by covering out-of-the-pocket costs like deductibles, coinsurance, and copayments, while Medicare Advantage also includes the Original Medicare, which covers Part D, eye, dental, and ear care but not all plans do.

Medigap plans allow you to see any doctor or use any hospital of your choice who accepts Medicare while Medicare Advantage has carrier networks. You may have to pay a higher cost if you go out of the network.

Medigap has standard plans that are labeled with letters, every plan with the same letter offers the same coverage regardless of which carrier you bought it from, while Medicare Advantage plans have lower premium rates than Medigap. Although you may pay more in the form of copayments and coinsurance.
