A Medigap policy, also known as a Medicare supplement, is designed to supplement the medical coverage provided through the Medicare program. Because Medigap policies vary in cost and coverage, it’s important to find a policy that matches your needs.
Do I Need a Medigap Policy? The first thing to consider is whether you need coverage to fill gaps left by Medicare Part A and Part B. Medigap can help cover coinsurance, copayments, deductibles, and some services Original Medicare doesn’t pay for.
For more on how Medigap works and how claims are handled, see Understanding Medigap Policies and Insurance Claims.
What Are the Medigap Options? Medigap plans are standardized and labeled A through N. Each plan letter offers a specific set of benefits, so match a plan’s features to your current and anticipated needs.
Plans A through G generally provide more extensive coverage than K and L but typically cost more. Newly sold Medigap policies cannot include prescription drug coverage, so most people who need drug coverage enroll in a separate Medicare Part D plan.

Medigap Pricing Factors
- Some carriers offer discounts for non-smokers or for certain group memberships.
- Medigap policies sold as Medicare SELECT may require use of specific hospitals or providers for full benefits, which can affect price.
- Some standardized plans, like Plan F, offer a high-deductible option that lowers premiums in exchange for a higher out-of-pocket deductible.
- Carriers may use attained-age, issue-age, or community rating to set premiums, which affects how rates change over time.
- Underwriting can affect price unless you apply during your Medigap open enrollment period or under guaranteed-issue rights set by law.
The best way to find the right Medigap policy at a good price is to comparison shop and make sure you compare the same plan letter across carriers. Your state insurance department or a local resource can help you identify what carriers offer in your area; see Medicare Supplement and Disability/Individual Health Insurance for more carrier information.
