Understanding Medicare Supplement
Learn how Medicare Supplement (Medigap) coverage works and what it covers
Medicare Supplement
Medicare Supplement (Medigap) plans
A Medicare Supplement plan, or Medigap policy, supplements your Original Medicare benefits.
These plans provide medical-only coverage, and benefits are guaranteed renewable as long as you pay your premium.
How it works
Medicare Supplement plans, also known as Medigap, are designed to “close the gaps” in Original Medicare and pay for costs Original Medicare doesn’t cover.
You’ll also have the freedom to travel or live anywhere in the United States and receive plan benefits from any provider that accepts Medicare assignment.
What it helps cover
Medigap plans help cover your Medicare copays, coinsurance and deductibles.
Each type of Medigap plan offers different benefits and premium costs. Some plans also offer optional coverage for an additional premium.
What you pay
Costs vary depending on the plan you choose, and you must continue to pay your Part B premium along with your monthly Medicare Supplement plan premium, deductibles, copays and coinsurance.
What you should know
Medicare Supplement eligibility
To enroll in a Medicare Supplement plan, you must be eligible for Medicare Part A and enrolled in Part B.
Prescription drug coverage
Medigap plans do not include prescription drug coverage, so you’ll need to sign up for a stand-alone Part D prescription drug plan to avoid a penalty.
Applying for a Medigap plan
You may be required to submit a health history with your application when applying for a Medigap plan.
Guaranteed issue rights
Guaranteed issue rights are protections that let you enroll in a Medigap plan in certain situations without health questions or coverage denials based on your health.
