Best Medicare Supplement plans

Medicare can be confusing with all the different letters thrown around. Still, it’s essential to understand what they mean. First, you must realize that Medicare Supplement insurance or Medigap has “Plan” letters, and Original Medicare has “Parts.” We’re discussing the top 5 Medicare Supplement plans and what they cover. There are 10 Medigap Plan options.

However, most Medicare beneficiaries enroll in one of the top three Medicare Supplement insurance plans. The top five Medicare Supplement plans are Plan C, D, F, G, and N.

Top 5 Medicare Supplement plan Chart

Medicare Supplement Plan G

Beneficiaries that started Medicare on or after January 1, 2020, flock to Plan G. Similar to Plan F, it covers all of your Medicare cost-sharing with only one exception. It doesn’t cover Medicare’s small calendar year Part B deductible.

Once that’s met, the coverage is identical to Plan F. The monthly premiums will usually be lower than Plan F even after you pay the Medicare Part B deductible. Plan G, like Plan F, has a high deductible plan called HDG. It works just like the HDF.

Medicare Supplement Plan N

Plan N is the plan that budget-conscious beneficiaries choose. This option has a similar coverage level to Plan G, with minor differences. When you see a healthcare provider, you’ll pay a small copay of up to $20 and a $50 copay for an emergency room visit.

Medicare Supplement Plan C

Medigap Plan C is a popular plan almost identical to Plan F. The only difference in coverage is that it doesn’t cover the Part B Excess Charges. Like Plan F, Plan C isn’t available to beneficiaries that are new to Medicare.

It doesn’t cover the Medicare Part B excess charges. The lower premiums of Plan N make this plan a desirable offer for savvy seniors.

Medicare Supplement Plan D

Medigap Plan D has a similar relationship with Plan G as Plan C does with Plan F. The coverage is the same as Plan G, except the Part B excess charges aren’t covered.

Medicare Supplement Plan F

When it comes to filling in the gaps in Original Medicare’s out-of-pocket costs from Medicare Part A and Medicare Part B, Plan F is the long-reigning champion. It covers all of your portion of the Medicare cost-sharing. Plan F has a high-deductible version called Plan HDF.

This is a good option for beneficiaries who don’t visit the doctor often but want a low maximum out-of-pocket. Unfortunately, enrollment in Plan F is only available to Medicare beneficiaries eligible before 2020.

What are the gaps in Medicare?

When you hear the term gaps regarding Medicare, it refers to costs for which the beneficiary is responsible. These costs are all related to the cost-sharing under Original Medicare. Medicare Part A and Part B have cost-sharing such as deductibles, copays, and coinsurances. These costs are what are referred to as gaps.

Picking your Medigap policy

When choosing the correct Medicare Supplement insurance, there are a few details to consider. Still, since Medigap plans are standardized, shopping around is more manageable.

Every carrier offers the same programs, so you compare the company’s price and quality once you select the plan letter for your situation.

The first thing to consider when you’re enrolling is your situation. You can choose any plan without needing medical underwriting if you’re in your Open Enrollment Period. If you’re in a Guaranteed Issue situation, you can enroll in specific plans without underwriting.

However, suppose you’re not in either of these periods. In that case, you’ll be required to undergo a health qualification process to be approved for coverage.

Once you have determined the enrollment situation, review your budget. Enrolling in a plan that’s more than you can afford doesn’t do any good. Medicare Supplement plan premiums will typically increase annually.

If you start at the maximum of your budget, you could quickly find yourself looking to change plans.

Then, take an honest look at your health and family health history of what runs in your genetics. If you’re healthy and don’t go to the doctor often, a Plan N is an excellent option with its lower price point.

If you aren’t as healthy or have a family history of health issues, perhaps a more comprehensive plan such as Plan G would be more valuable.

What impacts the Medicare Supplement prices?

Several factors can impact your monthly premiums as well as rate increases. The most significant impacts on your monthly premium are where you live, your age, and if you use tobacco. If you need to qualify medically, this could also affect your rates. Some insurance companies will rate you up if you have specific healthcare conditions.

For rate increase, the most significant factors have to do with the financial strength of the company and the claims for the plan you choose. Let’s take a deeper look at these two situations. AM Best is a company that rates the financial strength of insurance companies.

A higher rating indicates stronger financial backing. This is important because if they were to have a bad year, they have the financials to absorb it better and not have to raise rates significantly to offset it.

Claims history is a significant factor as well. Since Plan F and Plan G, depending on when you started, Medicare can be purchased in a Guarantee Issue situation, more sick people can enroll in those plans.

Since more sick people are filing claims, the rate increases more than plans you have to get in Open Enrollment or an underwritten situation.

Plan N is a good example. Plan N can only be issued without underwriting in Open Enrollment. Since some small out-of-pocket costs exist, sick people tend not to enroll in this plan. This lowers the claims and keeps the rates more stable.

This makes Plan N the most affordable of the top 5 Medicare Supplement plans for .
