Medigap plans G and N are both supplemental insurance plans offered by private insurance companies to help cover Medicare’s out-of-pocket costs. Plan G is slightly more comprehensive than Plan N.
Medicare supplement plans, called Medigap plans, provide coverage for some of the out-of-pocket costs associated with Medicare. These costs may include:
- deductibles
- copays
- coinsurance
You can enroll in a Medigap plan if you have Original Medicare (Medicare parts A and B).
Though private insurance companies sell Medigap plans, the federal government standardizes the coverage you receive with them. That means that all Medigap Plan G plans offer the same coverage, regardless of the company selling it.
However, a few states — Massachusetts, Minnesota, and Wisconsin — standardize their plans differently, and not all plans are available in all locations.
Keep reading to learn the differences between Medicare supplement plans G and N, including coverage, costs, and more.
Medigap plans cover costs associated with Original Medicare that you would otherwise pay out of pocket. A Medicare supplement plan can help lower your healthcare costs and make them more predictable.
Medigap plans do not cover services not covered under Original Medicare, such as dental, hearing, and vision care, like prescription eyeglasses. However, some Medicare Advantage (Part C) plans offer coverage for these services.

Medigap Plan G provides comprehensive coverage compared to other supplement plan options.

- Part A coinsurance and deductible
- any hospital costs you incur up to an additional 365 days after using up your Medicare benefits
- Part A coinsurance or copayment for hospice care
- coinsurance for a skilled nursing care facility

- Medicare Part B excess charges, if you visit a health facility that charges more than the Medicare-approved amount for a particular service
- up to 80% of emergency medical care during travel outside the United States (based on plan limits)
While some plans have a yearly out-of-pocket limit after which the Medigap plan covers 100% of your costs, Plan G does not have an out-of-pocket limit.

It’s best to enroll in a Medicare supplement plan during your initial enrollment window, which typically begins when your Medicare Part B coverage starts and lasts 6 months.
If you enroll during this time, your application will not be subject to medical underwriting. This means that during the initial enrollment period, insurance companies cannot deny you Medigap coverage or raise your monthly prices based on any underlying medical conditions you may have.
This is not the case outside of your initial enrollment period.
You can enroll outside of your initial enrollment period or switch from one Medigap plan to another during open enrollment. However, you may have to pay a higher monthly premium for coverage.
Note that you cannot enroll in a Medicare supplement plan if you are enrolled in a Medicare Part C (Advantage) plan. These plans are only available to people enrolled in Original Medicare.
Medicare supplement plans G and N both help cover out-of-pocket costs associated with Original Medicare and can make your healthcare costs more predictable.
Plan G offers slightly more comprehensive coverage than Plan N, and you will likely pay a slightly higher premium. Plan G covers Medicare excess charges, which you may incur if a healthcare facility charges more than Medicare’s approved amount for a particular service. Plan N does not cover excess charges.
There are various Medicare supplement plans, all with different coverage. It’s best to shop around to find a plan that meets your needs and budget.
