If "All other systems negative except as marked" is included, how many elements are needed for ROS?

To determine the number of elements needed for the Review of Systems (ROS) when "All other systems negative except as marked" is included, it is essential to understand the context of a comprehensive ROS. This phrase indicates that other systems have been reviewed but do not need to be elaborated upon because they are negative.

In this context, only the systems that are marked as having issues need to be counted. Therefore, if only one or two systems are identified as positive or needing further detail, you only need to elaborate on those. Thus, in situations where the ROS is succinct and positive findings are limited, just two elements are necessary to fulfill the criteria for documentation.

This contrasts with requiring a more extensive number of elements if multiple systems are altered or if the documentation policy specifies a minimum total number of systems that must be reviewed. In the case we are considering, since the phrase implies most systems are negative, the requirement is effectively reduced. Hence, acknowledging two elements typically suffices when the focus is on the exceptions.
