About 33259: Extensive atrial ablation with bypass
Reports extensive surgical ablation for atrial fibrillation performed with cardiopulmonary bypass during another cardiac operation, as an add-on to that procedure.
This add-on covers an extensive surgical lesion set in the atria to treat atrial fibrillation while the patient is undergoing another cardiac operation with cardiopulmonary bypass. A cardiac surgeon typically performs it in the operating room during open-heart surgery, such as mitral valve surgery or coronary artery bypass grafting. The ablation is performed alongside the primary operation rather than as a standalone service.
Report 33259 only with the primary cardiac procedure when the operative record supports extensive atrial ablation and cardiopulmonary bypass. Documentation should identify the atrial ablation performed, its extent, use of bypass, and the primary operation. Distinguish it from limited ablation and extensive ablation without bypass when selecting among related codes. CMS treats this as an add-on: it is billed with a primary procedure and paid within that procedure's global period.

33259 billing questions
Can 33259 be billed by itself?
No. It is an add-on for extensive atrial ablation performed with cardiopulmonary bypass during another cardiac procedure, and must be reported with the primary procedure.
How does 33259 differ from 33258?
Both represent extensive atrial ablation as an add-on during another cardiac procedure. 33259 is the choice when cardiopulmonary bypass is used; 33258 is for the corresponding service without bypass.
When is 33257 a better choice?
Use 33257 for limited atrial ablation with cardiopulmonary bypass during another cardiac procedure. 33259 describes an extensive ablation with bypass.
Does cardiopulmonary bypass alone support 33259?
No. The record must support the extensive atrial ablation as well as use of bypass during the primary cardiac operation.
What should the operative report document?
Document the atrial ablation and its extent, whether cardiopulmonary bypass was used, and the concurrent primary cardiac procedure.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
