Medicare Supplement Plan K covers the basic set of benefits. These basic benefits include most Medicare Part A and B coinsurance amounts, blood, and additional hospital benefits not covered by Original Medicare. Plan K also covers the Part A Deductible(50%) and Skilled Nursing Facilities(50%). Medicare Supplement Plan K has an out-of-pocket annual limit of $5,880 in 2020.
Medicare Supplement Plans K, L and 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.
