Shortness of breath

This code represents the subjective sensation of difficult or labored breathing, often described by patients as "air hunger" or not being able to get enough air. It is a symptom, not a diagnosis, indicating an underlying physiological issue affecting the respiratory or cardiovascular system.

Assign this code when the patient's medical record explicitly documents shortness of breath as a presenting symptom or a current complaint, and a more specific definitive diagnosis for the underlying cause has not yet been established or is not being coded. Documentation should clearly state the patient's experience of dyspnea.

• Do not code this symptom if a definitive diagnosis explaining the shortness of breath (e.g., asthma, heart failure, pneumonia) is established and coded.
• Consider sequencing this code as a primary diagnosis if it is the reason for the encounter and the definitive cause is unknown or being investigated.
• Differentiate from other respiratory symptoms like cough (R05) or wheezing (R06.2) unless all are documented.
