Choose the Coverage You Need First, not the Insurance Company.

There are dozens of companies that sell Medicare Supplement insurance, so how do you know which company to choose? Rest assured MedicareWire has been reviewing plans and carriers since 2012. Here's what you need to know.

Key Takeaways

  1. Medicare Supplements (aka, Medigap plans) are standardized. That means a Medicare Supplement Plan F from Aetna has the same coverage as a Plan F policy from AARP (UnitedHealthcare).
  2. The best time to buy a Medigap policy is when you first qualify for Medicare benefits. For most people, this is on their 65th birthday. This is when beneficiaries have a guaranteed-issue right.
  3. Supplemental Medicare insurance benefits people with chronic health conditions the most. The top 3 plans (F, G, and N) cover the major gaps in Original Medicare.
  4. People with a Medigap plan pay the majority of their healthcare costs in advance, but the overall cost is generally less than Original Medicare alone or a Medicare Advantage plan.

Choose the Plan Before the Insurance Company

One of the most challenging aspects of Medicare insurance is separating the mass media marketing from what is best for you, the Medicare Beneficiary. So, before we ever talk about our plan picks, we feel that it is important to reiterate one of the top benefits of Medicare Supplements.

Medigap plans are standardized.

The following Medicare Supplement comparison chart shows what each standardized Medigap plan covers. Down the left-hand column, you have all of the shared costs (i.e., coverage gaps) in Original Medicare. Across the top, you have each lettered plan (A, B, C, D, etc.).

2023 Medicare Supplement Plans Comparison Chart

NOTE: It's easy to confuse Medicare Parts A, B, C, and D with Medigap Plans A, B, C, and D. Medicare organizes its coverage in "Parts". Private insurance offers "Plans".

Which Medicare Supplement is the Best?

One of the most common questions people ask us about Medigap insurance is, “Which Medicare Supplement is the best?”

It’s a great question, but the answer is different for everyone. The reason this is true is that there are so many different factors, including:

  1. Where you live
  2. Your age
  3. Your health
  4. Your finances and financial goals
  5. Your use of tobacco

Let’s talk about some plans and the reasons you might choose one over another.

When “Best” = “Most Coverage”

For some, the question of best means getting the most coverage. Medigap Plan F offers the most coverage possible. It covers ALL the cost gaps in Original Medicare (Part A and Part B).

Unfortunately, Plan F is no longer available (Congress put the kibosh on Part B deductible coverage) for new seniors. As a result, Medigap Plan G is the next best (most coverage) available.

The good news is that the overall cost of a Plan G policy + the annual Part B deductible generally makes Plan G a better deal anyway. You can refer back to the chart above for a visual way to compare what each lettered plan covers.

When “Best” = “Good Coverage with Some Out-of-Pocket Costs”

As retirees (or approaching retirement), many of us find ourselves on a fixed budget. At the same time, we may be super healthy or have a chronic condition that’s easily managed through medications and does not require a specialist.

If this is your situation, a Plan F or G policy might be too expensive or simply wasteful. In this case, a Medigap Plan N policy could be an excellent option to consider. Here’s why.

In most areas, a Plan N policy can run 20-30% less than a Plan G. Even more when compared to a Plan F. If you are a healthy senior, the monthly premium difference really adds up.

Plan N is so much lower than Plan F and G because you take on some of the costs. For example, with a Plan N policy, you pay up to $20 when you see your doctor and up to $50 to use the emergency room.

But… because you’re healthy, these are rare occurrences. And, your annual wellness exam is excluded. This doctor visit is covered 100% by Medicare.

If you have a chronic condition that you and your primary care physician are managing through medication, without involving a specialist, Plan N could be a cost-saving option for you, as well. It all depends on how frequently you need to see your doctor and whether you pay Excess Charges to see your doctor(s).

Part B Excess Charges are additional fees (up to 15%) that doctors may charge if they do not accept Medicare-assignment (Medicare’s standard rates). Medigap Plan N does not cover Excess Charges, whereas Plan G does. If you are not in this situation with your doctor, that’s another plus in the Plan N column.

And that’s it. If paying a small copay to see your doctor and not having coverage for Excess Charges works for you, add Plan N to your shortlist.

When “Best” = “Lowest Monthly Cost + Risk Protection”

One aspect of Medigap coverage that I like to point out is how it compares to Medicare Advantage. Many people ask me why they should consider a Medigap plan when some Medicare Advantage plans have a zero-dollar monthly premium.

To truly understand this question, you need to look at total cost vs. risk. With a Medigap policy, you pay most costs in advance via monthly premiums. With a Medicare Advantage plan, you pay most costs at the point of service via copays.

This fundamental difference lulls some people into a false sense of lower cost with a Medicare Advantage plan. The reality is that the only people who experience lower costs in a Medicare Advantage plan vs. a Medigap plan are healthy people who rarely need healthcare services.

However, there is one aspect of Medicare Advantage that is very beneficial. It’s called MOOP (Maximum Out-of-Pocket), and it applies to Medicare Advantage copays and coinsurance costs. With these plans, you are protected by an annual MOOP, which is currently no more than $6,700 per year, in-network, or $10,000 if you use out-of-network providers.

Those are scary numbers, but you need to consider that with Original Medicare, there are no limits or out-of-pocket protections. None. Nada. Zip!

So, that brings us to Medigap Plan K.

Like Plan N, with Medicare Supplement Plan K you share some of the costs (see the chart above). But, unlike Plan N, there’s an annual limit on your out-of-pocket costs with Plan K (currently $5,880). When you hit the MOOP with Plan K, all Medicare Part A and B charges are paid for you at 100% for the remainder of the year.

This is a plan option for people who need to manage their budget and can take a little risk because they have good health, or their health condition(s) do not necessitate frequent health services.

Here are some recent examples:

  1. 65 year-old woman, Naples, FL:
    • Plan G: $169.23/mo
    • Plan K: $60.65/mo
  2. 65 year-old man, Phoenix, AZ:
    • Plan G: $113.50/mo
    • Plan K: $41.15/mo

Your rates will be based on your location, age, gender, etc. These are two examples for comparison purposes.

Look to the Future First when Choosing a Medigap Plan

One of the most difficult lessons anyone can learn when it comes to their health insurance is that when you need it the most, it's too late to buy more coverage. 

One of the services we offer here at MedicareWire.com is a free analysis of Medigap insurance rates in your area. If you'd like one simply fill out this form (no spam, no sales calls, no mailing lists, no kidding!).

On a daily basis, we get requests for our free Medigap quote service from folks who check the "Best Plan for Chronic Conditions" box. It's heartbreaking when we see that the person is already over age 65 because they no longer have their guaranteed issue right. As a result, when they apply for Medicare Supplement insurance they are frequently turned down. If they are accepted, it's generally in a plan with a lot less coverage than they want or need.

Here's some sage advice. Plan for the future. The old adage, "Hope for the best, but plan for the worst" applies perfectly to Medicare Supplement insurance.  Here's why.

  1. As we age our health tends to decline, but our retirement income does not. Budgeting early for the most insurance you can afford means that you won't struggle to pay your bills when your health declines.
  2. If you already have chronic health conditions when you first get your Medicare benefits, you may only have one opportunity to get the coverage you need for affordable health care. Most chronic health conditions, even when well-managed with prescription medications, do not pass medical underwriting with Medicare Supplement insurance companies. 

Medigap Plan F—Long Live the King

If you're familiar with Medigap plans, you might know that Medicare Supplement Plan F covers the most gaps. In fact, Plan F covers all of the gaps in Original Medicare (Parts A and B). That being the case, it's reasonable that Plan F would be at the top of our list for best Medicare Supplement plans, but it's not.

One of the benefits of our free Medicare Supplement quotes service is that we see rates from coast to coast. And, with the most coverage available, you'd expect Plan F to be the most expensive, but as of early 2020, the rates are all out of whack. Here's why.

A while back Congress voted to no longer allow insurance carriers to cover the Medicare Part B deductible. This is the deductible that Medicare beneficiaries pay when they see their doctor, get lab tests, need medical supplies, etc.  Two plans cover the Part B deductible, Plans F and C. As a result, these plans are no longer available if you qualify for Medicare benefits on or after January 1, 2020.

Even if these plans were available, they don't equal the benefits and value of our top pick. The reason this is true is because of the monthly premiums. In nearly all cases, the annualized cost of a Plan F premium exceeds the Medicare Part B deductible by a large margin. 

#1 Plan Choice: Medigap Plan G—Good as You Can Get

What makes Medicare Supplement Plan G our #1 choice is that it covers all gaps in Original Medicare except the Part B deductible. But the annualized cost of a Plan G policy, plus the annual Part B deductible, is almost always less than a Plan F policy. Although you don't get first-dollar coverage with a Plan G policy, as you do with Plan F, the overall cost savings makes it worth it.

What exactly makes a Medigap Plan G so great? Here's the shortlist:

People with a Plan G policy are covered for all of their major medical expenses. And, once the policy is issued, it cannot be canceled for any reason, so long as you continue to pay your monthly premiums.

#2 Plan Choice: Medigap Plan N—The Newest Plan Saves Healthy Seniors Money

Medicare Supplement Plan N is the newest of the 10 supplemental policies available today. It's our solid #2 choice because it offers excellent coverage while saving its enrollees a serious amount of money. How much money? Our studies show that, in most areas, a Plan N policy will save about $264 per year compared to a Plan G, and more than $624 per year compared to a Plan F.

Where a Plan N policy differs from a Plan G is in its Part B coverage. A Medicare Supplement Plan N does not cover the Part B Excess Charges and it does not pay the full coinsurance when you see your doctor or use the emergency room. For these services, a Plan N policyholder pays up to $20 and $50, respectively.

The lack of coverage for Part B Excess Charges and the small copays are what make Plan N such a great deal for healthy seniors. Think about it, if you rarely see your doctor for anything other than your annual checkup, which Medicare covers 100%, you are unlikely to incur excess charges or pay the copays.

In other words, for healthy seniors who maintain their good health, a Plan G policy is a waste of money.  Here's an idea to think about, healthy seniors. Get a Plan N policy and put the money you save vs. a Plan G in a savings account to use when and if you ever need it.

#3 Plan Choice: Medigap Plan K or L—Share Costs and Save Even More

If you are on the fence about Medigap vs. Medicare Advantage, it pays to have a look at Medicare Supplement Plan K and L. These are cost-sharing plans that offer a maximum out-of-pocket limit (MOOP), just like Medicare Advantage plans.

Why get one of these plans instead of a Medicare Advantage plan? The reasons are many, but here are our top reasons:

  1. No provider networks. Choose any doctor or specialist that accepts Medicare.
  2. Inpatient hospitalization costs will be lower.
  3. Coverage travels with you anywhere you go in the USA (no foreign travel coverage).
  4. Doctor visits and other Medicare Part B costs are on par with the best Medicare Advantage plans.

A couple of years ago the Kaiser Family Foundation did a study and found that most people with a Medicare Advantage plan will pay more for a five or more day stay in the hospital than people with Original Medicare alone. What does that mean?

If you have a chronic health condition that requires occasional hospital stays, a Plan K or Plan L policy will cost you less out-of-pocket than a Medicare Advantage plan. The same may be true when it comes to your copays, depending on how often you see your doctor, specialist, and your need for tests and medical supplies.  Currently, Plan K's MOOP is $5,880 per year, and Plan L is at $3,110 per year (2021 rates). Compare this to the majority of Medicare Advantage plans, which range from $4,800 to $7,550 per year.

Can you afford to pull up to $7,550 out of your pocket for your inpatient and outpatient care? What about the hassle of using provider networks and getting referrals?

Although most Medicare Advantage plans offer additional benefits, the cost of the additional benefits, including their copays, does not factor into the annual MOOP. The maximum out-of-pocket limit is only your copays and coinsurance when you use healthcare services.

Anyone considering a Medicare Advantage plan because they believe it will save them money would be well-advised to look at Plans K and L. And be sure to read our analysis on the 7 reasons Medicare Advantage plans are bad.
