How many systems are recognized for purposes of Review of Systems (ROS)?

The correct count of recognized systems for the purpose of the Review of Systems (ROS) is 14. In a medical audit context, the Review of Systems is a systematic approach that helps healthcare providers gather comprehensive information about the patient’s health status across multiple organ systems.

The 14 systems typically addressed include:

1. Constitutional symptoms (weight loss, fever, etc.)
2. Eyes
3. Ears, Nose, Mouth, and Throat (ENT)
4. Cardiovascular
5. Respiratory
6. Gastrointestinal
7. Genitourinary
8. Musculoskeletal
9. Integumentary (skin and/or breast)
10. Neurological
11. Psychiatric
12. Endocrine
13. Hematologic/Lymphatic
14. Allergic/Immunologic

Each of these systems addresses different health issues and provides a structured way for clinicians to document patient reports, which is crucial for diagnosis and treatment planning. The 14 systems ensure that a thorough review covers significant aspects of the patient’s health, which ultimately supports high-quality care and appropriate coding practices.
