Medicare Supplement Plan K

Medicare Supplement Plan K covers the basic set of benefits. These basic benefits include most Medicare Part A and Part B coinsurance amounts, blood, and additional hospital benefits not covered by Original Medicare. Plan K also covers 50% of the Part A Deductible and Skilled Nursing Facilities co-insurance at 50%. Medicare Supplement Plan K has an out-of-pocket annual limit of $6,220 in 2021.

Medicare Supplement Plan K, Plan L and Plan M combined, accounted for 1% of all Medigap plans sold in 2018. Plan K does not cover the Part B deductible and pays for half of the Part A deductible. Plan K is not offered by many insurance companies, and as a result, is one of the least popular Medigap plans. However, it is an affordable option for many people.
