What Are Medicare Lifetime Reserve Days? 
Under Medicare part A you will have a deductible for the first 60 days , a copay for next 60 days . After that you enter your lifetime reserve during which your Medicare cover is extended to a maximum of an additional 60 days during your lifetime at an even higher daily copay . Most people never use their lifetime reserve days but it does happen . After your lifetime reserve days are used you are responsible for 100 % of the costs .
