How we choose the best Medicare Supplement plans
To rate the best Medicare Supplement plans, NerdWallet's editorial team evaluates Medicare Supplement Insurance companies on factors including:
Prices for Medigap Plan G and Plan N in multiple metro areas.
Consumer complaint rates.
Availability and size of premium discounts.
Online price quote availability.
Range of Medigap plan types offered.
Medical loss ratio (the percentage of premiums spent for member benefits).
Breadth and type of extra non-Medicare perks included with plans.
We continually reevaluate and update our methodology to reflect evolving industry standards and consumer needs.
What’s the best Medigap plan for most people?
In most states, there are 10 standardized Medigap plan types. But the three most popular plan types cover about 88% of enrollees.
Here are the top three Medicare Supplement plans and what might make them a good fit.
Best for maximum coverage: Medigap Plan F
Medigap Plan F covers more than any other plan type.
Coverage for the Part B deductible sets Plan F apart from most other plan types. But People who turned 65 in 2020 or later can't buy Plan F or any other plan that covers the Part B deductible. (Plan G is a great alternative.)
What Plan F covers
Part A
Part A deductible.
Part A coinsurance for hospital, skilled nursing and/or hospice care.
Part B
Part B deductible.
Part B coinsurance.
Part B excess charges.
Other
Blood (first 3 pints).
Foreign travel emergency care.
Consider Plan F if you want the maximum possible Medicare Supplement coverage, and you became eligible for Medicare in 2019 or earlier.
Pros
- More benefits than any other plan type.
- Offered by most companies.
- Covers most out-of-pocket costs for Part A and Part B.
Cons
- Pricey premiums.
- Not an option for new Medicare members.
- Plan G or Plan N might be a better value.
Best coverage for new Medicare members: Medigap Plan G
Medigap Plan G is nearly identical to Plan F, except it doesn't cover the Medicare Part B deductible.
What Plan G covers
Part A
Part A deductible.
Part A coinsurance for hospital, skilled nursing and/or hospice care.
Part B
Part B coinsurance.
Part B excess charges.
Other
Blood (first 3 pints).
Foreign travel emergency care.
Consider Plan G if you want the most coverage available to new Medicare members. Or if you’re eligible for Plan F, check if Plan G might end up a better deal due to lower premiums.
Pros
- Very high coverage.
- Sold by nearly every company.
- Available to any Medicare member.
Cons
- Higher premiums.
- Plan N might be a better value.
- Coverage for Part B excess charges might not be relevant.

Best for cost-effective coverage: Medigap Plan N
Medigap Plan N has coverage similar to Plan G with two notable differences:
Plan N doesn’t cover Medicare Part B excess charges (if a provider is permitted to charge more than Medicare’s approved amount and does so). These are rare, but could be pricey.
You’ll owe copays of up to $20 for medical office visits and up to $50 for emergency visits that don’t result in admission to inpatient care.
What Plan N covers
Part A
Part A deductible.
Part A coinsurance for hospital, skilled nursing and/or hospice care.
Part B
Part B coinsurance.
Other
Blood (first 3 pints).
Foreign travel emergency care.
Consider Plan N if you want plenty of coverage with lower premiums than Plan G or Plan F. It’s an especially good fit if you don’t expect many doctor’s office and/or emergency visits.
Pros
- Plenty of coverage.
- Lower premiums than Plan G or Plan F.
- Available from most companies.
Cons
- Copays for office and emergency visits.
- Part B excess charges could be costly if you run into them.

Find the right Medicare Supplement Insurance plan
Because Medigap plans are standardized, you can get precisely the same Medicare benefits from any company offering the plan. So when you shop, keep these considerations in mind to find the best policy to fit your needs:
Is your preferred plan available? Health insurance companies don’t always sell every plan, so check who sells the plan you want to buy in your area.
What are the premiums? Prices for the same plan can vary between companies, so check to find the most competitive rates.
Will your premiums change over time? Most policies cost more as you age, but some companies offer policies that let you lock in a price when you sign up.
Are there extras? Medigap plans’ core benefits are standardized, but in certain cases, some companies include such perks as discount programs or gym memberships.
You may be eligible for Medicare plans during a special enrollment period if you are turning 65, new to Medicare plans, moving or losing coverage.

Medicare Supplement Insurance ratings methodology
NerdWallet’s Medicare Supplement Insurance (Medigap) ratings are based on pricing, discounts, plan types offered, complaint data from the National Association of Insurance Commissioners, consumer experience, additional perks and benefits, and more. To calculate each health insurance company's rating, we adjusted the scores to a curved 5-point scale, rounded to the nearest half star.
NerdWallet reviewed 15 Medicare Supplement Insurance companies based on highest enrollment and greatest online search volume. At the national level, our scored reviews include companies covering about two-thirds of all Medigap beneficiaries. At the state level, our research includes at least one of the two largest Medigap insurance companies in 48 of the 50 states, plus Washington, D.C.
These ratings are a guide, but we encourage you to shop around and compare several insurance quotes to find the best coverage and rate for you. NerdWallet does not receive compensation for any reviews. Read our editorial guidelines and full ratings methodology for Medicare Supplement Insurance.
Insurer complaints methodology
We examined complaints received by state insurance regulators and reported to the National Association of Insurance Commissioners. To assess how insurers compare to one another, the NAIC calculates a complaint index each year for each subsidiary, measuring its share of total complaints relative to its size, or share of total premiums in the industry. To evaluate a company’s complaint history, we calculated a similar index for each insurance company, weighted by market shares of each subsidiary. We score companies based on this index of how many complaints the company receives relative to its market share.
