Question: For an evaluation and management (E/M) visit, if the physician states ROS as noted in the patient’s HPI, can you count the diagnoses in the HPI toward the ROS? Virginia Subscriber Answer: Simply put, the answer is no. The review of systems (ROS) is a documented account of the patient’s responses to an inventory review of various body systems. The provider should not take notes documented as a part of the patient’s history of present illness (HPI) and incorporate them into the ROS portion of the E/M visit.
