Ventricular arrhythmia refers to irregular heartbeats originating in the ventricles. In the International Classification of Diseases, Tenth Revision (ICD-10), these conditions are classified under specific codes. The precise code depends on the type of arrhythmia, such as ventricular tachycardia or fibrillation. Consulting the official ICD-10 manual or a medical coding expert is essential for accurate diagnosis and billing purposes. Correctly identifying and coding these arrhythmias is crucial for appropriate patient care and data analysis.
