How many systems must be reviewed in a Complete ROS?

A Complete Review of Systems (ROS) requires the assessment of a total of 10 or more systems. This assessment is essential for a comprehensive evaluation of the patient, allowing healthcare providers to gather extensive information regarding various systems of the body.

The ten systems typically included in a Complete ROS are:

1. Constitutional

2. Eyes

3. Ears, Nose, Mouth, Throat

4. Cardiovascular

5. Respiratory

6. Gastrointestinal

7. Genitourinary

8. Musculoskeletal

9. Integumentary (skin and breast)

10. Neurological

An extensive ROS helps in thoroughly documenting a patient's health status, which is particularly critical in surgery and cardiovascular assessments where multiple organ systems can be affected. The requirement for a minimum of 10 systems distinguishes a Complete ROS from a Problem-Focused or Expanded Problem-Focused ROS, which would involve fewer systems.

Understanding the requirements for a Complete ROS is vital for accurate coding and documentation within cardiovascular and thoracic surgery practices, ensuring that the services provided are appropriately billed and reflective of the care delivered.
