We have all heard the old "double dipping" rule when it comes to using the HPI for the ROS. We attended a workshop yesterday where the presenter stated "you cannot use information for the HPI for the ROS". Our MAC (Novitas) has stated it is not double dipping and I have a copy of a letter (from 1998) from an official at CMS stating there is no need for the physician to repeat the same information in both the HPI and ROS. We are trying to find where the "double dipping rule" originated. Does anyone have any information on that? Thanks!
