Atrial premature depolarization

This code represents an early electrical impulse originating in the atria, occurring before the next anticipated normal heartbeat. It is a common type of supraventricular arrhythmia characterized by an abnormal P wave on an electrocardiogram (ECG) and a premature QRS complex. While often benign, frequent occurrences can sometimes indicate underlying cardiac issues.

Use this code when documentation clearly indicates the presence of premature atrial contractions (PACs) or atrial premature beats identified on an ECG or Holter monitor. This diagnosis is typically made based on electrophysiological findings rather than symptoms alone. It is appropriate for both symptomatic and asymptomatic presentations of this specific arrhythmia.

• Differentiate from other supraventricular arrhythmias like atrial fibrillation or flutter; this code is specific to premature atrial depolarizations.
• Do not use this code if the premature beats are ventricular in origin; those would be coded separately.
• Always review the ECG interpretation or cardiologist's report for definitive diagnosis of atrial premature depolarizations.
