ICD-10 Code I47.0 – Re-entry ventricular arrhythmia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I47.0 – Re-entry ventricular arrhythmia
What it is
I47.0 identifies a ventricular tachyarrhythmia caused by a re-entry circuit within the ventricles. Use it for documentation that specifically states re-entry ventricular arrhythmia rather than a more general rhythm disturbance.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records describe a ventricular-origin arrhythmia on ECG or telemetry, with rapid wide-complex rhythm and possible palpitations, dizziness, syncope, or hemodynamic instability.
When to use this code
Use this code when the provider documents re-entry ventricular arrhythmia, ventricular re-entry tachycardia, or an equivalent diagnosis. It is also appropriate when the note clearly ties the arrhythmia to a re-entry mechanism in the ventricles. If the mechanism is not stated, check documentation before assigning I47.0.
Do not use for
Do not use I47.0 for atrial arrhythmias, nonspecific tachycardia, or ventricular fibrillation. If the record only says “arrhythmia” or “SVT,” you need clearer documentation.
Coding tip
Look for the exact phrase “re-entry” in the provider’s diagnosis or interpretation before coding I47.0.
