0.000What This Code Means
A dangerous rapid heartbeat originating in the lower chambers of the heart that is caused by a circular electrical pattern within the ventricles.
Coding Tips
- •Re-entry arrhythmias involve a circular pathway of electrical conduction
- •This is a serious arrhythmia that may require emergency intervention
Clinical Significance
Re-entry ventricular arrhythmia is a dangerous cardiac rhythm disturbance where electrical impulses circulate in a loop within the ventricles, causing rapid, potentially unstable heart rates. This can degenerate into ventricular fibrillation and cardiac arrest. It often requires antiarrhythmic therapy, catheter ablation, or implantable cardioverter defibrillator placement.
Documentation Requirements
- ✓Provider diagnosis of re-entry ventricular arrhythmia
- ✓Electrocardiogram or electrophysiology study findings
- ✓Documentation of the re-entry mechanism
- ✓Associated symptoms (palpitations, syncope, hemodynamic instability)
- ✓Treatment plan (antiarrhythmics, ablation, implantable cardioverter defibrillator)
