How Medigap works
Medicare Supplement insurance works with Original Medicare.
A Medigap policy does not replace Medicare. Original Medicare pays first, then the policy helps with certain deductibles, coinsurance, and copayments according to its standardized plan letter.

What stays consistent
The letter defines benefits. The carrier defines the price and service.
- AStandardized benefits
A Plan G from one insurer has the same standardized medical benefits as Plan G from another insurer.
- BDifferent premiums
Premiums, discounts, rate history, and household eligibility can differ by company.
- CBroad provider access
You generally can see providers nationwide who accept Medicare; there is no private plan medical network.
- DSeparate drug coverage
Medigap policies sold after 2005 do not include prescription drug coverage.
Popular plan letters
Compare how Plan G, Plan N, and High-Deductible G share costs.
This focused chart compares three commonly reviewed options. It is not a complete list of every Medigap plan, and availability and premiums vary by insurer and location.
Plan N at a glance
Lower premiums with some cost sharing
Plan N leaves the annual Part B deductible to you and can include office and emergency-room copays. It does not cover Part B excess charges.
High-Deductible G at a glance
Lower premium approach with a larger deductible
You pay Medicare-covered costs until the $2,950 2026 plan deductible is met. After that, Plan G benefits apply, including Part B excess charges.

Enrollment timing matters
Your first Medigap window is usually the most flexible.
Your one-time federal Medigap Open Enrollment Period lasts six months, beginning the first month you are 65 or older and enrolled in Part B. During this window, an insurer cannot use medical underwriting to deny a policy it sells in your state.

FAQ
Frequently asked Medicare questions
Browse all Medicare FAQsIs a Medicare Supplement the same as Medicare Advantage?
No. A Supplement works with Original Medicare. Medicare Advantage is a private plan that provides your Medicare benefits through that plan.
Can I apply later?
You may be able to apply later, but medical underwriting can apply outside certain protected enrollment windows.
Do Supplements include drug coverage?
Generally no. Most people who choose a Supplement also review a standalone Part D plan.
What is California's Medigap birthday rule?
Current California Medigap policyholders generally have a 60-day period beginning on their birthday to move to a policy with equal or fewer benefits without medical screening or a new waiting period.
