ICD-10 Code I47.20 – Ventricular tachycardia, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I47.20 – Ventricular tachycardia, unspecified
What it is
I47.20 identifies ventricular tachycardia when the record does not specify the type or cause. It is a rapid rhythm that starts in the ventricles and may be sustained or nonsustained.
Clinical signs
Common findings include a wide-complex tachycardia on ECG and symptoms such as palpitations, dizziness, syncope, or hemodynamic instability. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents ventricular tachycardia but does not name a more specific form, such as monomorphic or polymorphic VT. It also fits when the chart confirms VT without an underlying etiology. If the note gives a more specific diagnosis, code that instead.
Do not use for
Do not use this code for supraventricular tachycardia, atrial fibrillation, or ventricular fibrillation. If documentation identifies a different arrhythmia or a more specific VT type, choose the documented code.
Coding tip
Query the provider when the rhythm strip or note says “wide-complex tachycardia” but VT is not explicitly documented.
