Managing Editor Medigap Plan L is a Medicare Supplement Insurance plan that helps pay for certain out-of-pocket expenses associated with Medicare Part A and Part B coverage. Plan L may offer lower premiums because unlike other plans, it pays for 75% rather than 100% of most benefits.
How it works
After Medicare pays for its portion of covered services, Medigap plans help pay for the out-of-pocket costs that are left over. Medigap plans only work for beneficiaries with Original Medicare — Medicare Advantage members can’t buy a Medigap plan.
There are 10 standardized Medigap plans available in most states (except Massachusetts, Minnesota and Wisconsin, which use different standards). The plans differ in terms of coverage for services, out-of-pocket limits and premium costs.
Medigap Plan L pays for 75% of most of its covered services. (It’s similar to Plan K, which pays 50%.) So if you were billed for a $100 Part B coinsurance, Plan L would cover $75, and you’d owe the other $25 out of pocket.
Medigap Plan L also has an out-of-pocket limit — another feature it shares only with Plan K. When you reach Plan L’s limit of $4,000 in 2026, the plan pays for 100% of its covered services until the end of the calendar year.

What Medigap Plan L doesn’t cover
Here are the benefits Medigap Plan L doesn’t cover that are included in some other plans:
- Medicare Part B excess charges (if a provider is permitted to charge more than Medicare’s approved amount and does so).
- Emergency care during travel outside the U.S.
Additionally, all Medigap plans — including Plan L — sold to new Medicare members don’t cover the following:
- Part B deductible (since 2020, new Medicare members can’t buy any plan that covers the Part B deductible, although existing members may own older plans that do).
- Prescription drugs (that's Medicare Part D).
- Long-term care (like non-skilled care you get in a nursing home).
- Private-duty nursing.

How much does Medigap Plan L cost?
Plan L has lower premiums than most other Medigap options as a result of its reduced coverage. While the plan is regulated by the government, the private companies that sell policies set the prices. Premiums vary according to factors including age, location and tobacco use.
In Atlanta, a metro area with average costs for Medicare Supplement Insurance, Medigap Plan L premiums for a 65-year-old female nonsmoker start at $139 per month, before any discounts.
🤓 Nerdy Tip
The cheapest Medigap Plan L policy has the same standardized Medicare coverage as one that costs much more. Companies may add on extra perks like discounted gym memberships, but the core Medicare benefits are the same, so go ahead and compare based on price. You can get the best price and have the easiest time enrolling in a Medigap plan during your Medigap open enrollment period.
This period happens only once. It starts once you’re 65 and enrolled in Medicare Part B, and lasts for six months. (If you're still working after 65 and covered by a group employer plan that is deemed creditable coverage, your six-month period starts after you’ve ended active employment or no longer have that insurance.)
Medigap policies are cheapest and easiest to get during this open enrollment period because insurance companies aren’t allowed to factor your health or medical history into your price. After the period ends, the prices may go up or you may be denied coverage due to your health status or medical history.
In some states, insurance companies sell Medigap plans to those under 65 who are living with a disability and are eligible for Medicare. You can find more information through your State Health Insurance Assistance Program, or SHIP.
