Medicare Supplement Plans K, L and N
Help manage your expenses
Plans K, L and N offer the same basic benefits as other Medicare Supplement insurance plans, but provide you with a lower monthly premium. In exchange for a lower premium, these cost-sharing plans cover less of the coinsurance and copayments than other Medicare Supplement insurance plans. Plans K and L do offer an out-of-pocket maximum, which limits the amount you will have to pay each year.
In general, Plan K offers a lower monthly premium than Plan L, but offers higher coinsurance amounts and a higher annual out-of-pocket limit.
Medicare Supplement Plan K
With Medicare Supplement Plan K, the plan covers services similar to other Medicare Supplement insurance policies. However, instead of paying all your costs, the plan pays a percentage. If you have a serious illness or injury, you have the protection of an out-of-pocket annual limit. Once you reach this "cap" on your out-of-pocket costs, the plan pays 100 percent of Medicare-approved costs for the rest of the year. This plan is a good option if you prefer a lower premium but still want a fair amount of coverage for a wide variety of services.
Medicare Supplement Plan K coverage:
- 100% coverage for Part A hospitalization coinsurance plus coverage for 365 days after Medicare benefits end
- 100% Hospice coverage for Part A coinsurance
- 50% of Medicare-eligible expenses for the first three pints of blood
- 50% Part B coinsurance, except for preventive care services, which are covered 100%
In addition to the basic benefits, Plan K also provides coverage for:
- 50% coverage for Skilled Nursing Facility coinsurance
- 50% coverage for your Medicare Part A deductibles
- $4,620 out-of-pocket annual limit (The out-of-pocket annual limit will increase each year for inflation)
Medicare Supplement Plan L
Medicare Supplement Plan L is another option if you want a Medicare Supplement insurance policy with an affordable premium, but still want a reasonable amount of coverage for a wide variety of services. This plan is similar to Plan K, except it:
- covers a higher percentage of your costs
- offers a lower annual out-of-pocket amount and out-of-pocket limit
- has a slightly higher monthly premium
Medicare Supplement Plan L covers:
