According to the guidelines, how many types of ROS are defined?

The correct response is based on the structure of the Review of Systems (ROS) component within the Evaluation and Management (E/M) documentation guidelines. The guidelines delineate three distinct types of ROS:

1. Problem-focused ROS - This involves asking questions related only to the system pertinent to the presenting problem or concern.

2. Expanded problem-focused ROS - This entails obtaining a review of systems related to the problem at hand plus a limited review of other systems, typically asking about a few systems that are not directly related to the primary issue.

3. Complete ROS - This type requires an exhaustive review of all body systems, where the provider must obtain information on at least ten different systems or a combination of systems.

Understanding these three types of ROS is crucial for accurate coding and ensuring compliance with E/M documentation requirements. Each type has its own set of expectations regarding the depth and breadth of questions asked, which significantly influences the complexity of the visit and eventual coding. This classification further informs the level of medical decision-making and the overall service provided during patient encounters, impacting healthcare billing accurately.
