Can you insure a parent under a company medical insurance policy?

Perhaps, if the parent is a bona fide dependent of yours. Do you claim the parent as such on your taxes? Best to check with the insurance carrier and your particular plan's exclusions, etc. No, Only the following family sizes are allowed. (A) One adult (B) One adult and any children (C) Two adults,and (D) Two adults and any children I am not aware of any states that allow parents, even disabled ones, on an employees certificate of coverage.
