These types of policies can cover all types of odd stuff. They can substitute for a workers comp policy if you’re in a profession or non-profession that doesn’t have Workmen’s Comp. Except it also covers you for accidents that happen when you’re not at work. Pays your wages if you miss time for work. Is also a long term disability policy if you encounter a disabling condition. Also can have some life insurance policy type benefits. (I am not an actuary but I am guessing that it is the long term disability that gets very expensive for them)
