Question:
A patient arrives for a redo PVI due to evidence of continuing atrial fibrillation. The EP study performed demonstrates continued PVI block. 3D mapping and programmed stimulation with Isuprel elucidates that the patient is having episodes of mitral annulus atrial flutter that is ablated. How should this situation be coded?
Answer:
Report code 93653 for ablation of mitral annulus atrial flutter along with code 93623 and for Ispurel study. 3D mapping is a component of 93653 and not reported separately. Although the intended procedure plan was to perform a redo pulmonary vein isolation, electrophysiology studied identified that the patient had complete PVI entry and exit block so no treatment of atrial fibrillation via pulmonary vein isolation was rendered in this situation.
