Respiratory arrest

This code signifies the cessation of breathing, a life-threatening event where the lungs stop functioning. It indicates a complete absence of respiratory effort, leading to an inability to exchange oxygen and carbon dioxide.

Apply this code when documentation explicitly states "respiratory arrest" as a diagnosis. This is typically used in acute care settings, such as emergency departments or intensive care units, following an event where a patient's breathing has stopped.

• Always sequence this code as a principal diagnosis when it is the reason for admission.
• Do not confuse with respiratory failure (e.g., 518.81, 518.83), which implies inadequate breathing rather than complete cessation.
• Look for underlying causes of the respiratory arrest, which should be coded additionally.
