Medigap Plan G is the most comprehensive Medicare Supplement Insurance plan that all Medicare members can buy. It’s also the most popular of these plan types
Plan G covers nearly all of the out-of-pocket expenses associated with Medicare Part A and Part B, such as copays, coinsurance and deductibles. (Medigap plans sold to people who became eligible for Medicare after 2019 can’t cover the Medicare Part B deductible — $240 in 2024 — so Plan G doesn’t cover that cost
Since it can be difficult or impossible to change Medigap plans after the end of your Medigap open enrollment period, it’s a good idea to choose your Medigap Plan G company carefully.

Mutual of Omaha Corporate Communications. Email Confirmation. Accessed Feb 9, 2024.

Cheaper Medicare Select plans have network requirements.
Why we like it: Blue Cross Blue Shield licensees offer Medigap policies everywhere in the country. Broadly speaking, BCBS companies offer competitive prices and have roughly average complaint rates — but because different BCBS companies serve different locations, pricing, perks and member experience can vary. It’s worth looking at the Blue Cross Blue Shield options in your area to see how their Plan G offerings compare to other top companies.
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.
Here’s an overview of our top picks for Medigap Plan G:

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 13 Medicare Supplement Insurance companies based on highest enrollment and greatest online search volume. 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. NerdWallet conducts its data analysis and reaches conclusions independently and without the endorsement of the NAIC.
