The subcomponents of the E/M history section include which of the following?

The Review of Systems (ROS) is a crucial component of the Evaluation and Management (E/M) history section. It involves a systematic approach where the physician or healthcare provider gathers information related to various bodily systems from the patient. This helps in identifying any additional issues that may not be immediately apparent or mentioned in the patient's main complaint. The ROS is essential in forming a comprehensive picture of the patient's health, guiding diagnosis and treatment planning.

The other options—Social Security number, insurance policy details, and current medications—while relevant to patient management and office procedures, do not specifically make up the E/M history component. The Social Security number is primarily used for identification and insurance purposes, insurance policy details pertain to billing and coverage, and current medications may be noted in the medication history but are not classified as part of the E/M history section specifically. Therefore, the ROS stands out as the correct choice in relation to the components that make up the E/M history section.
