Ask Dr. Z

We coded the case that follows with codes 93656, 93613, 93662, 93623, and 93657 x 3 (or should it be x 4??). Is this correct? Are the posterior wall, left atiral septum, linear line connection the LIPV to mitral annulus and the right atrial isthumus each a separate ablation that can be billed with code 93657?

Patient with atrial fibrillation was brought in for ablation. ICE and 3-D mapping are documented. Physician documents wide area circumferential lesions set were created around the four pulmonary veins to isolate the ostium of the veins from the left atrium. Isolation was confirmed. Patient then had ablation of the CFAE sies on the posterior wall and left atrial septum. Linear line was created connection the LIPV to the mitral annulus. Atrial flutter was then induced, and ablation of the right atrial isthmus was done. Isuprel was administered, and atrial flutter could not be induced. Procedure ended.
