Jun 20, 2026
Summary
This policy establishes coverage criteria for catheter ablation procedures (radiofrequency, cryoablation, and pulsed field ablation) to treat atrial fibrillation. Coverage is considered medically necessary for symptomatic paroxysmal or persistent AF that has failed antiarrhythmic medications, as an alternative to AV nodal ablation in heart failure patients, or as initial treatment for recurrent symptomatic paroxysmal AF when rhythm control is desired.
Action Required
Immediately: Review current catheter ablation claims for atrial fibrillation to ensure documentation supports the medical necessity criteria outlined in this policy. Billing team should verify that claims include evidence of failed antiarrhythmic medication trials for symptomatic AF or documentation supporting alternative indications. Update prior authorization processes to align with the specific coverage criteria for paroxysmal and persistent AF cases.
