Paroxysmal supraventricular tachycardia

This code represents a type of supraventricular tachycardia characterized by sudden onset and termination, originating above the ventricles. It involves a rapid, regular heart rhythm, typically between 150-250 beats per minute, due to re-entrant pathways or abnormal automaticity within the atria or AV node. Patients often experience palpitations, dizziness, shortness of breath, or chest discomfort during episodes.

Use this code for documented episodes of paroxysmal supraventricular tachycardia (PSVT) where the specific mechanism (e.g., AVNRT, AVRT) is not further specified or is unknown. This code is appropriate when physician documentation clearly indicates a diagnosis of PSVT based on ECG findings or clinical presentation.

• Do not use this code if the specific type of supraventricular tachycardia, such as atrial fibrillation or atrial flutter, is documented.
• Ensure documentation specifies "paroxysmal" to differentiate from persistent or chronic forms of SVT.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting care.
