Tens of millions of people are covered by Original Medicare (Part A and Part B). Almost one quarter of those people choose a medigap plan for additional coverage. In 2023, three of the top Medigap plans are: Medicare Plan F, Medicare Plan G and Medicare Plan N. If you are like a lot of people, you may be unsure which of these plans offers the best coverage for you.
An average couple in their mid sixties spends more than half of their Social Security benefits on things related to their healthcare. If you are worried about the out-of-pocket costs associated with healthcare, choosing a Medigap plan may work for you.
Which Medigap Plan is Best?
When choosing between Medigap Plans, Plan F is the best Medigap plan if you are looking for the most comprehensive coverage. It covers everything that Medicare doesn’t. The main difference between Plan F and Plan G is that Plan G does not cover the Part B deductible. The next popular plan is Plan N. Plan N is just like plan G, but in addition to not covering the Plan B deductible, it also does not cover your excess charges, and has a small $20 copay for doctors.
How Does Medigap Work?
Federal and state laws govern how Medigap plans work. Each of the 10 Medigap plans are standardized. This means that a plan has the same coverage no matter which state you live in or what company you purchase your plan through. The benefits and coverage of the plans never changes, although the premiums may vary.
Federal and state laws govern how Medigap plans work, but the plans are administered by private insurance companies. Each company that offers Medigap insurance does not have to offer all 10 of the plans. In order to be allowed to offer Medigap coverage, an insurance company must offer Plan A. If a company chooses to offer more than Plan A, they must offer either Plan C or Plan F as well as any other plans they want to offer.
Plan F is by far and away the most popular plan. However, Plan N and Plan G are both quickly gaining a lot of popularity. Here is how you can make the best choice between all of the plans and find the one that will work best for you.

Plan F: A Closer Look

- It pays your excess charges.
Cons:
- This plan is only available if you were eligible for Medicare before 2020.
- If you want lower premiums when choosing between Medigap plans, you can choose to enroll into a high deductible Plan F to pay a deductible which is $2,370 in 2021, before your benefits kick in and in exchange, you pay lower premiums ($30-40 a month).
What Plan F Covers:
- Deductibles for Part A & Part B

Pros:
- Extensive coverage for health crises
- This plan is available to everyone who is eligible for Medicare.
Cons:
- Plan B deductible is not covered by Plan N.

Plan N covers everything that Plan F covers, EXCEPT for the Plan B deductible, your excess charges, a $20 copay for doctors visits, and a $50 copay for emergency room.
Can I Change My Medigap Plan?
Yes, you will be able to change your Medigap plan. However it is very important to understand that once your open enrollment period ends, you will have to apply for any new coverage. This means to get a new plan, you will have to answer medical questions and be subject to underwriting. Further, your acceptance is no longer guaranteed. After your open enrollment period ends, if you apply for different coverage you can be denied. There are a few guaranteed acceptance periods available but they may vary by state and circumstances.
