A patient with mitral regurgitation was placed on cardiopulmonary bypass and underwent minimally invasive mitral valve repair via a small thoracotomy using a heart port device. What is the correct ICD-9-CM procedure code for repair of mitral valve using a heart port access device?
Assign code 35.12, Open heart valvuloplasty of mitral valve without replacement, for mitral valve repair, and code 39.61, Extracorporeal circulation auxiliary to open heart surgery, for cardiopulmonary bypass. The port access is the surgical approach and inherent to the total procedure.
Port access valve surgery allows surgeons to operate via small incisions (ports) underneath the breast instead of cutting through the sternum. This technique can lessen operating time and aortic cross-clamping. Another innovative minimally invasive technique for valvular surgery is the endoscopic video-assisted approach. This technique involves visualization via endoscope through the right chest, peripheral cannulation for extracorporeal circulation and endo-aortic balloon clamping.
