Documentation Required
- Patient age documented (must be >= 18 years for coverage under this policy).
- Clinical documentation of the specific arrhythmia diagnosis (e.g., AVRT, preexcited AF, CTI-dependent atrial flutter, non-CTI atrial flutter, AVNRT, focal AT, junctional tachycardia, PVCs, ventricular tachycardia/fibrillation).
- Electrocardiographic evidence and/or EP study documentation confirming arrhythmia mechanism and localization (EP study reports, intracardiac recordings, inducibility, mapping data).
- For accessory pathway ablation: documentation of EP study findings including any 'high-risk' characteristics identified on EP testing (when applicable).
Key Coverage Criteria
- Transcatheter ablation of supraventricular tachycardia (CPT 93653) is medically necessary in adults (>= 18 years) for: accessory pathway ablation in individuals with atrioventricular reentrant tachycardia (AVRT), preexcited atrial fibrillation (AF), or high-risk findings on an electrophysiological (EP) study.
- Transcatheter ablation of supraventricular tachycardia (CPT 93653) is medically necessary in adults (>= 18 years) for: cavotricuspid isthmus (CTI)-dependent atrial flutter.
- Transcatheter ablation of supraventricular tachycardia (CPT 93653) is medically necessary in adults (>= 18 years) for: CTI-dependent atrial flutter induced at the time of AF ablation.
- Transcatheter ablation of supraventricular tachycardia (CPT 93653) is medically necessary in adults (>= 18 years) for: recurrent symptomatic non-CTI-dependent atrial flutter.
- Transcatheter ablation of supraventricular tachycardia (CPT 93653) is medically necessary in adults (>= 18 years) for: symptomatic atrioventricular nodal reentrant tachycardia (AVNRT).
- Transcatheter ablation of supraventricular tachycardia (CPT 93653) is medically necessary in adults (>= 18 years) for: symptomatic focal atrial tachycardia (AT) as an alternative to pharmacological therapy.
