ICD-10 Code I47.2 – Ventricular tachycardia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I47.2 – Ventricular tachycardia
What it is
Ventricular tachycardia is a fast heart rhythm that starts in the ventricles. Use this code when documentation identifies VT or sustained ventricular tachycardia as the diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Common findings include a wide-complex tachycardia on ECG, palpitations, dizziness, syncope, or hemodynamic instability.
When to use this code
Assign I47.2 when the provider documents ventricular tachycardia as the active condition being evaluated or treated. It also applies when VT is confirmed on ECG or telemetry and is the reason for admission, consultation, or monitoring.
Use the code for sustained or nonsustained VT only when the record supports the diagnosis. Check documentation if the rhythm is described only as “wide-complex tachycardia” without a confirmed ventricular source.
Do not use for
Do not use this code for supraventricular tachycardia, atrial fibrillation, or sinus tachycardia. If the rhythm is unspecified or not confirmed as ventricular, check documentation.
Coding tip
Code VT only when the provider documents it clearly; if the tracing is ambiguous, query for the final rhythm interpretation.
