Blue Cross Blue Shield Medicare Supplement Insurance plans
Blue Cross Blue Shield companies offer different selections of Medigap plan types depending on the state and company. There are as many as eight Medicare Supplement Insurance plan types available for purchase by any Medicare member:
Medigap Plan A — the basic benefits included in every Medigap plan without any extras.
Medigap Plan B — basic benefits plus coverage for the Medicare Part A deductible.
Medigap Plan D — a mid-cost option that covers most Medigap benefits.
Medigap Plan G — the highest-coverage option available to new Medicare members. Available as either a standard plan or a high-deductible option in some locations.
Medigap Plan K — the lowest-cost Medigap plan, with 50% coverage for most benefits.
Medigap Plan L — a low-cost option with 75% coverage for most benefits.
Medigap Plan M — coverage for most benefits, but only half of the Part A deductible.
Medigap Plan N — a plan with lower premiums but higher copays.
Blue Cross Blue Shield also offers Medigap Plan C, Medigap Plan F and the high-deductible version of Plan F in certain locations for qualifying beneficiaries who were eligible to enroll in Medicare prior to 2020. Newer Medicare members can’t buy these plans from any company.
BCBS plans in Massachusetts, Minnesota and Wisconsin fit each state’s respective standards. (These states use different Medigap plan systems than most of the country).
Blue Cross Blue Shield’s plan offerings vary by state. In some states, multiple BCBS companies can offer different selections of plans. Enter your ZIP code on Blue Cross Blue Shield’s website to check out the BCBS company and plan offerings available in your location.
More Nerdy Perspective
It depends. Taken all together, Blue Cross Blue Shield plans are pretty average. But BCBS is a collective of more than 30 companies, and their offerings and performance vary. You’ll need to look into your local BCBS licensee to check whether it’s a good fit. While you’re at it, it's a good idea to compare quotes from several other companies. Also consider working with a licensed insurance agent or broker to select the right Medigap company for you.
Medicare Select policies add network requirements
In some locations, Blue Cross Blue Shield companies offer Medicare Select versions of policies in addition to the standard version.
Medicare Select plans require you to get non-emergency inpatient care at in-network hospitals. In exchange, they might have lower premiums than the non-Select version.
Review the materials for a Medicare Select policy you’re considering to learn about the network limitations and in-network facility list for the policy.
Add-on coverage for dental and vision
Some plans allow you to purchase additional coverage with cost sharing for services not included in standard Medigap policies. For example, some Anthem Blue Cross Blue Shield plans offer Anthem Extras packages, which can cover some costs for dental cleanings, dental procedures and eye exams, plus an allowance for eyeglasses or contact lenses.
These add-ons require premiums in addition to the cost of the Medigap policy. For example, Anthem Extras packages with dental and vision coverage in Georgia cost between $19 and $48.40 per month depending on the coverage level.
How much does Blue Cross Blue Shield Medicare Supplement Insurance cost?
Blue Cross Blue Shield Medigap premiums vary depending on the BCBS licensee. In our analysis, BCBS tended to have more competitive premiums for Plan G than Plan N. Plan G premiums averaged about 25% higher than the least expensive alternative. For Plan N, BCBS premiums were about 58% higher.
- How we evaluate Medigap companies’ prices
We compare prices in three cities. Each city has different average Medigap premiums:
Los Angeles: Higher costs. Blue Shield of California is the BCBS licensee.
Atlanta: Average costs. Anthem Blue Cross Blue Shield is the BCBS licensee.
Dallas: Lower costs. BlueCross BlueShield of Texas is the BCBS licensee.
We use Plan G and Plan N for price comparisons. New Medicare members usually pick one of those plan types.
The sections below show price estimates filed with the Centers for Medicare & Medicaid Services. Prices are for a 65-year old female nonsmoker. (Note: Some Medigap prices may be higher for males.)
Our tables compare the company’s prices to the cheapest alternative. For example, Blue Cross Blue Shield's best price for Plan G in Los Angeles is next to the lowest price from any company on Medicare.gov for the same plan.
Plan G
BCBS price | Medicare.gov lowest price | |
|---|---|---|
Los Angeles | $176. | $162. |
Atlanta | $149. | $120. |
Dallas | $144. | $101. |
Plan N
BCBS price | Medicare.gov lowest price | |
|---|---|---|
Los Angeles | $166. | $124. |
Atlanta | $159. | $86. |
Dallas | $117. | $75. |
Blue Cross Blue Shield Medigap discounts
Average discounts
Discounts can help you save on your Medigap premiums. We often see “household” discounts offered to people living with at least one other adult.
Blue Cross Blue Shield household discounts vary by location and BCBS company. We saw discounts ranging from about 7% to 10%.
In two of the three locations we priced, BCBS offered “roommate” discounts that don’t require you to live specifically with a spouse. The third location had a spouse-specific household discount.
Available discounts may also vary according to factors such as your location, household status and how you apply for a policy.
Blue Cross Blue Shield member complaints
13% more complaints than average
Blue Cross Blue Shield companies have relatively average complaint rates. BCBS members file about 13% more complaints than the average for all Medigap companies. That’s according to 2022 to 2024 data from the National Association of Insurance Commissioners (NAIC).
NerdWallet conducts its data analysis and reaches conclusions independently and without the endorsement of the NAIC.
Blue Cross Blue Shield's spending on care
83.2% for member benefits
Blue Cross Blue Shield plans spent about 83.2% of premiums on member benefits, according to the most recent annual data. (The other 16.8% went to overhead expenses like administrative costs, marketing, salaries and commissions.) For comparison, the average for all companies is 83.9%.
Medicare Supplement Insurance companies must report data on the premiums they collect and how much they spend to provide benefits for members. The minimum required by law for individual Medigap policies is 60%.
Additional benefits
Medigap plans have standardized Medicare benefits, but insurance companies can offer additional perks. Here are examples of extras included with some Blue Cross Blue Shield Medicare Supplement Insurance policies:
Fitness: Some plans offer SilverSneakers or similar fitness programs that can include gym memberships, fitness classes, training sessions and tracking apps.
Discount programs: Some plans offer discounts on things like prescriptions or vision, hearing and/or health and wellness products and services.

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.
If you have additional questions about Medicare, visit Medicare.gov or call 800-MEDICARE (800-633-4227, TTY 877-486-2048).

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. NerdWallet conducts its data analysis and reaches conclusions independently and without the endorsement of the NAIC.
