Which Medigap Plans Are Most Popular?

Christian Worstell by Christian Worstell    |    Published Oct 03, 2019    |    Reviewed by John Krahnert

The most popular Medicare Supplement Insurance plan is Medigap Plan F, according to 2019 statistics from America’s Health Insurance Plans (AHIP).1

Plan F accounted for 55% of all Medigap policies in 2017.

Medigap Plan F vs. Plan G vs. Plan N vs. Plan C

While Plan F is the most popular plan, Medigap Plan C, Plan G and Plan N are the next most popular Medicare Supplement Insurance plans.

In 2017:

  • 13% of Medigap beneficiaries were enrolled in Plan G
  • 10% of Medigap beneficiaries were enrolled in Plan N
  • 6% of Medigap beneficiaries were enrolled in Plan C

The table below ranks the 2017 popularity of the 10 Medigap plan options currently available for purchase in most states.

These plans are standardized everywhere except Minnesota, Massachusetts, and Wisconsin, which have different options.

Popularity Ranking* Plan Name Total Enrollment in 2017 Share of Total**
1 F 7,062,798 55%
2 G 1,660,548 13%
3 N 1,280,507 10%
4 C 781,070 6%
5 B 251,163 2%
6 D 160,726 1%
7 A 145,124 1%
8 K 82,066 1%
9 L 49,295 0.5%
10 M 4,785 0.5%
*Information is based on AHIP statistics. **The percentages in this column do not add up to 100% because discontinued plans (Plans E, H, I, and J) and waiver states (Massachusetts, Minnesota and Wisconsin) are not included.

The least popular Medigap plans are cost-sharing plans, such as Plan K and Plan L, and newer plans, such as Plan M.

Is Medigap Plan F the Best?

There are several reasons why consumers choose certain Medigap plan options over others.

Plan F is the most popular Medicare Supplement insurance plan, and Plan C is also very popular. These are both the most benefits-rich plans in the Medicare Supplement insurance market.

Plans F and C are often called “first-dollar coverage” Medigap plans because each covers all of the Medicare deductibles and co-insurance.

Plan F and Plan C Are Disappearing for New Medicare Beneficiaries in 2020

Beneficiaries who become eligible for Medicare after January 1, 2020, won’t be able to purchase Medigap Plan F or Plan C.

If you become eligible for Medicare before Jan. 1, 2020, you may still be able to enroll in Plan F or Plan C if they are offered where you live.

If you already have Plan F or Plan C, you will be able to keep it after 2020.

What Do the Most Medicare Supplement Plans Cost?

Although first-dollar coverage Medigap plans are the most popular, some beneficiaries may choose other plans based on their premiums and costs that they cover.

The chart below shows the average cost of each Medicare Supplement Insurance plan premium per month in 2018.2

The chart below illustrates the average cost of each type of Medicare Supplement plan in 2019.

Plan Monthly Premium Annual Premium
A $192.33 $2,308
B $141.24 $1,695
C $189.88 $2,279
D $157.33 $1,888
F $169.14 $2,030
High deductible F $57.16 $686
G $122.78 $1,473
J $160.07 $1,921
K N/A N/A
L N/A N/A
M $218.75 $2,625
N $111.28 $1,335

* Medigap Plan J was discontinued for new enrollees in 2010. Only beneficiaries who enrolled in the plan prior to that time may be currently enrolled in Plan J.

How Do Medicare Supplement Companies Determine Plan Costs?

Medicare Supplement Insurance companies can charge different premiums for policies depending on a number of factors, including age and location. 

Monthly premiums can change over time, especially if you purchase a plan that factors your age into its pricing strategy. Ask a licensed insurance agent about how the company determines its rates before you purchase a plan. Medigap policies can be priced in one of three ways:

  • Community-rated
    Also called no-age-rated, these policies cost the same amount for everybody on that particular type of Medigap plan, regardless of how old you were when you bought it. Older people are not charged more per month with these plans.

  • Issue-age-rated
    Premiums are lower for younger buyers of these types of Medicare Supplement Insurance plans, as they are priced according to when you purchase the policy (or when the policy was issued to you). Your monthly premium is determined at the start of your policy and does not continue to go up over time due to age.

  • Attained-age-rated
    With these plans, premiums always correspond to your current age (or the age you have “attained”). Premiums increase over time to reflect the increased risk to the insurer as you get older. These may start out relatively inexpensive, but they often become the most expensive Medigap plans over time.

Note: Premiums can always go up over time due to inflation or other factors, regardless of the company’s pricing structure.

Why Should I Compare Medicare Supplement Plans?

Comparison shopping is important because two different insurance companies could charge you a different price for a plan with the same benefits. For example, every Plan C policy provides the same benefits, but two insurers may charge you very different prices for a Plan C policy.

Comparing plan prices from multiple insurance carriers helps ensure that you get a competitive rate for the plan you want.

Changes in Medicare Supplement Insurance Plan Popularity

Medigap plans fluctuate in popularity from year to year. The AHIP report tracked enrollment changes from 2014 to 2017.

The table below details AHIP statistics regarding the enrollment figures and percent changes during that time period.

Plan Name Total Enrollment – 2014 Total Enrollment – 2017
A 165,483 145,124
B 346,086 251,163
C 1,064,386 781,070
D 213,572 160,726
F 6,008,216 7,062,798
G 697,682 1,660,548
K 58,166 82,066
L 45,571 49,295
M 995 4,785
N 761,495 1,280,507

Medicare beneficiaries can enroll in any available Medigap plan, regardless of its popularity. Despite this, is it helpful to review the options and reasons why hundreds of thousands or even millions of people choose one plan over another.

Enrolling in a Medigap Plan

If you enroll in Medigap during your Medigap open enrollment period (the six months after you are at least age 65 and enrolled in Medicare Part B), insurance companies cannot refuse to sell you a Medigap policy or charge you more for a plan based on your health history.

Some people who are under 65 are also eligible for Medicare and Medigap, such as people with End-Stage Renal Disease or other qualifying disabilities. However, you don’t have the same blanket guaranteed-issue rights that pertain to people over 65.

The easiest way to compare Medigap plans and rates in your area is with the help of a licensed insurance agent. Agents can answer questions and help you find the right plan for your needs.
