Coding

Procedure codes referencedCPT

93653	Comprehensive electrophysiologic evaluation with insertion and repositioning of multiple electrode catheters, induction or attempted induction of an arrhythmia with right atrial pacing and recording and catheter ablation of arrhythmogenic focus, including intracardiac electrophysiologic 3- dimensional mapping, right ventricular pacing and recording, left atrial pacing and recording from coronary sinus or left atrium, and His bundle recording, when performed; with treatment of supraventricular tachycardia by ablation of fast or slow atrioventricular pathway, accessory atrioventricular connection, cavo-tricuspid isthmus or other single atrial focus or source of atrial re- entry.
93655	Intracardiac catheter ablation of a discrete mechanism of arrhythmia which is distinct from the primary ablated mechanism, including repeat diagnostic maneuvers, to treat a spontaneous or induced arrhythmia (List separately in addition to code for primary procedure).
93656	Comprehensive electrophysiologic evaluation including transseptal catheterizations, insertion and repositioning of multiple electrode catheters with intracardiac catheter ablation of atrial fibrillation by pulmonary vein isolation, including intracardiac electrophysiologic 3-dimensional mapping, intracardiac echocardiography including imaging supervision and interpretation, induction or attempted induction of an arrhythmia including left or right atrial pacing/recording, right ventricular pacing/recording, and His bundle recording, when performed.
93657	Additional linear or focal intracardiac catheter ablation of the left or right atrium for treatment of atrial fibrillation remaining after completion of pulmonary vein isolation (List separately in addition to code for primary procedure).

Provider Actions & Documentation Requirements

Documentation Required

Document medical necessity using InterQual criteria

Providers must document in the medical record that the member meets the InterQual CP: Procedures, Electrophysiology (EP) Testing +/Radiofrequency Ablation (RFA) or Cryothermal Ablation, Cardiac criteria to support coverage.

Use InterQual CP: Procedures, Electrophysiology (EP) Testing +/Radiofrequency Ablation (RFA) or Cryothermal Ablation, Cardiac

Documentation Required

Medical records may be requested

Medical records documentation may be required to assess whether the member meets the clinical criteria for coverage; medical records may be requested and documentation does not guarantee coverage of the service requested.

Background & Evidence

This policy applies to UnitedHealthcare Commercial and Individual Exchange benefit plans and uses the InterQual clinical criteria to define clinical coverage for catheter ablation of atrial fibrillation. The policy notes that the U.S. Food and Drug Administration classifies ablation catheters for atrial fibrillation as Class III devices for which premarket approval (PMA) is required.
