92960

Cardioversion, elective, electrical conversion of arrhythmia; external (includes connection to monitor, recording of ECG, administration of sedative, cardioversion, and observation)

This procedure involves the elective, controlled delivery of an external electrical shock synchronized with the patient's R-wave to convert a symptomatic cardiac arrhythmia (e.g., atrial fibrillation, atrial flutter, or stable supraventricular tachycardia) back to a normal sinus rhythm. Unlike emergent defibrillation for pulseless rhythms (92950), this service is performed in a non-life-threatening situation to alleviate symptoms or prevent complications. The CPT code 92960 explicitly includes all components of the service: connection to a cardiac monitor, continuous recording of the electrocardiogram (ECG), the administration of sedative agents (when performed by the operating physician), the delivery of synchronized electrical shocks, and post-procedure observation.

Clinical Indications

  • Persistent or symptomatic paroxysmal atrial fibrillation refractory to medical management.
  • Persistent or symptomatic atrial flutter refractory to medical management.
  • Supraventricular tachycardia (SVT) unresponsive to vagal maneuvers or pharmacologic therapy, where the patient is hemodynamically stable.
  • Stable ventricular tachycardia (VT) with a pulse, refractory to antiarrhythmic medication, and where a planned, elective conversion is indicated.
  • Certain pre-excitation syndromes (e.g., Wolff-Parkinson-White syndrome) associated with hemodynamically significant tachyarrhythmias requiring rhythm control.

Procedure Steps

  1. Patient assessment, including medical history, physical examination, and consent for the procedure.
  2. Placement of cardiac monitoring electrodes and defibrillator pads on the patient's chest.
  3. Establishment of intravenous access and administration of conscious sedation (if performed by the operating physician, included in 92960).
  4. Synchronization of the defibrillator with the patient's R-wave to ensure electrical discharge occurs during ventricular depolarization, avoiding the vulnerable T-wave period.
  5. Delivery of one or more synchronized electrical shocks at escalating energy levels until normal sinus rhythm is restored or the procedure is deemed unsuccessful.
  6. Continuous post-procedure monitoring of cardiac rhythm, vital signs, and patient's recovery from sedation.
  7. Documentation of the procedure details, including arrhythmia type, energy levels used, number of shocks, medications administered, patient response, and final rhythm.

Coding Guidelines

  • Code 92960 encompasses the professional service for external electrical cardioversion. This includes the physician's work, necessary equipment, and, as per the CPT descriptor, the administration of sedative when performed by the operating physician.
  • If conscious sedation is provided by a separate, qualified healthcare professional (not the physician performing the cardioversion), it should be reported separately using the appropriate CPT codes (e.g., 99151-99157).
  • Do not report 92960 for unsynchronized defibrillation, which is typically performed in emergency cardiac arrest situations for pulseless ventricular fibrillation or tachycardia (reported with 92950, Cardiopulmonary resuscitation (CPR); by physician or other qualified health care professional).
  • This procedure has a 0-day global period. Services performed on the same day for unrelated reasons may be reported separately with appropriate modifiers.
  • Documentation must clearly state the indication for cardioversion, the specific arrhythmia being treated, the energy settings used, the number of shocks delivered, and the outcome of the procedure.
