I am a new coder and I recently had a case for a dog bite to the hand. The physician checked all organ systems on the ROS and the physical exam. I counted the GE, GU and PSYCH organ systems in my components for the ROS and physical exam, but I had an auditor tell me that these organ systems did not need to be counted because they did not pertain to the dog bite on the hand. Should I be counting any organ systems listed in my calculations for ROS and physicial exam, or only organ systems that pertain to each individual case? Any opinions would be appreciated. Thank you.
