Seeing the "Gray" in E/M Coding, Part 2 - Review of Systems and Past Family Social History

In a previous blog I wrote, "Seeing the “Gray” in Evaluation and Management Coding – Chief Complaint and History of Present Illness," I had started a dialogue related to Chief Complaint (CC) and History of Present Illness (HPI) gray areas. In this edition I hope to continue the conversation as it relates to review of systems (ROS) and past family social history (PFSH).
