CPT® Code 33256

The CPT® Code 33256 refers to an extensive operative procedure known as tissue ablation and reconstruction of the atria, specifically performed in a maze procedure with the use of cardiopulmonary bypass. This procedure is primarily indicated for the treatment of chronic atrial fibrillation, a condition characterized by rapid and uncoordinated contractions of the heart's upper chambers, leading to an irregular and often rapid heartbeat. The maze procedure aims to create new electrical pathways within the heart, allowing for the proper conduction of electrical impulses. This is achieved through a series of precise incisions made in the atrial tissue, which effectively interrupts the abnormal electrical signals that contribute to atrial fibrillation. By establishing these new pathways, the procedure helps restore normal heart rhythm and size of the atria, thereby improving the heart's ability to pump blood efficiently. The use of cardiopulmonary bypass during this procedure allows for better access to the heart and facilitates the surgical interventions required to achieve the desired outcomes.
