CPT® Code 0167T

Deleted

The procedure described by CPT® Code 0167T refers to the transmyocardial transcatheter closure of a ventricular septal defect (VSD) using an implant, specifically performed with the assistance of cardiopulmonary bypass. A ventricular septal defect is a congenital heart defect characterized by an abnormal opening in the ventricular septum, the wall dividing the left and right ventricles of the heart. This defect can lead to significant hemodynamic changes, including shunting of blood between the ventricles, which may result in heart failure or other complications if left untreated. The transcatheter approach allows for a minimally invasive repair of the VSD, utilizing devices such as the Amplatzer septal occluder, which is designed to effectively close the defect. The procedure involves navigating through the vascular system to reach the heart, where the occluder is deployed to seal the defect, thereby preventing the abnormal flow of blood and reducing the risk of further complications. The use of cardiopulmonary bypass during this procedure indicates that the patient's circulation is temporarily managed by a heart-lung machine, allowing for a controlled environment to perform the closure safely and effectively.
