Medicare Supplement Insurance Plans K and L

Plans K and L provide less coverage than other Medicare Supplement insurance plans but offer lower premiums and a maximum out-of-pocket limit. Depending on the state where you live, you could get 6% off your monthly premium if you enroll online. (Discount not available in CA, CT, OH and PA.)

What do Medicare Supplement Insurance Plans K and L cover?

Medicare Supplement Plan K

Plan K covers services similar to other Medicare Supplement insurance plans, but instead of paying all of your costs, it only pays a percentage. Another feature that makes Plan K different is the added protection of an out-of-pocket annual limit. Once you reach the limit, the plan pays 100% of Medicare-approved costs for the rest of the year.

In general, Plan K offers a lower monthly premium than Plan L, but higher coinsurance and a higher annual out-of-pocket limit.

Medicare Supplement Plan L

Plan L is similar to Plan K but covers a higher percentage of your costs and offers a lower annual out-of-pocket limit. This does, however, result in a higher monthly premium.
