Available 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 plans 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.

In addition, Blue Cross Blue Shield offers plans in Massachusetts, Minnesota and Wisconsin according to each state's Medigap plan standards, which differ from the standardization system used in the majority 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.

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. A Medicare Select policy covers the same benefits as the standard type, but it requires beneficiaries to get nonemergency services from in-network providers.

In exchange for the network restrictions, Medicare Select plans offer lower premiums than their non-Select counterparts.

If you have a Medicare Select policy and get services from an out-of-network provider, you’re not fully covered. You become responsible for some of the costs that the plan would cover if you had stayed in network. 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 glasses frames 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 Atlanta cost between $18 and $46 per month depending on the coverage level.

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).
