(1987) With the exception of what might be considered to be purely defensive pleading such as a setoff or recoupment, a counterclaim which seeks affirmative relief by asserting a new cause of action like a medical malpractice, although arising out of the same occurrence and although not barred at the commencement of the plaintiff's action, is barred if the counterclaim is filed at a time when it would have been barred as an original action.
