Supplemental Plan L
If you’re enrolled in Original Medicare, Part A and Part B, you probably know it comes with out-of-pocket costs, like deductibles and copayments. Medicare Supplement (Medigap) plans, available from private insurance companies, are designed to cover some of these expenses. Different Medigap plans cover different portions of your Medicare costs.
Medigap plans are standardized in most states; there are 10 of them, named with letter designations such as Medigap Plan L. (Massachusetts, Wisconsin, and Minnesota have their own standardized plans.)
Medigap Plan L includes somewhat less coverage of Original Medicare costs than most Medigap plans, but it does have a cap on your out-of-pocket spending, which most Medigap policies don’t have.
Because of the higher degree of cost-sharing, these Medigap Plan L policies sometimes have lower premiums than more comprehensive Medicare Supplement plans, such as Medigap Plan F. Medigap Plan L covers the basic benefits that all Medicare Supplement plans are required to offer, but covers some costs partially instead of fully.
