Postural orthostatic tachycardia syndrome [POTS]

This code identifies Postural Orthostatic Tachycardia Syndrome (POTS), a chronic condition characterized by an abnormal increase in heart rate upon standing, leading to symptoms such as dizziness, lightheadedness, fatigue, and syncope. It is a form of dysautonomia, affecting the autonomic nervous system's ability to regulate blood pressure and heart rate.

Apply this code when documentation clearly indicates a diagnosis of POTS, often confirmed by a tilt-table test or sustained heart rate elevation upon standing. This diagnosis is typically made by a cardiologist, neurologist, or electrophysiologist following a comprehensive evaluation of symptoms and objective findings.

• Ensure documentation specifies "Postural Orthostatic Tachycardia Syndrome" or "POTS" as the primary diagnosis.
• Do not confuse with other forms of orthostatic hypotension or syncope without the characteristic sustained tachycardia.
• Consider sequencing this code as the primary diagnosis when POTS is the reason for the encounter, or as a secondary diagnosis when it contributes to the patient's overall clinical picture.
