ICD-10 Code I47.19 – Other supraventricular tachycardia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I47.19 – Other supraventricular tachycardia
What it is
I47.19 identifies a supraventricular tachycardia that starts above the ventricles but does not fit a more specific ICD-10 category. Use it when the record documents an atrial or junctional tachycardia pattern and no narrower code is supported.
Clinical signs
Typical findings include a rapid, regular narrow-complex rhythm, palpitations, dizziness, or shortness of breath. Clinical features vary; refer to documentation, especially when the rhythm source is described as atrial or junctional.
When to use this code
Use this code when the provider documents other supraventricular tachycardia and the episode is not better described by a more specific arrhythmia code. It also fits when the note confirms SVT above the ventricles but does not name a subtype. Check documentation if the rhythm is postoperative, drug-induced, or part of a broader cardiac condition.
Do not use for
Do not use it for ventricular tachycardia or for a clearly named supraventricular subtype with its own code. Do not assign it when the record only says “tachycardia” without confirming a supraventricular origin.
Coding tip
Code I47.19 only after you confirm the rhythm is supraventricular and no more specific diagnosis is documented.
