In simple words: This procedure fixes a torn blood vessel in the chest using a heart-lung machine. The surgeon opens the chest, connects the patient to the heart-lung machine, and then fixes the tear in the blood vessel.The surgeon then closes the chest and disconnects the patient from the heart-lung machine.

Repair of a ruptured blood vessel within the chest, using cardiopulmonary bypass. This involves making an incision in the chest, exposing the ruptured vessel, and initiating cardiopulmonary bypass. The vessel is then repaired, either by tying off the open ends, or by suturing the edges of the rupture together. Blood flow through the repaired vessel is checked, the incision is closed, and the patient is taken off bypass.

Example 1: A patient presents with a ruptured thoracic aorta following blunt trauma. The patient is taken to the operating room where code 35211 is performed., A patient with a history of Marfan syndrome presents with a ruptured aortic aneurysm in the chest. The patient undergoes surgical repair using cardiopulmonary bypass (35211)., A patient undergoes a coronary artery bypass graft surgery. During the procedure, the surgeon accidentally tears the innominate vein. This requires an intrathoracic repair of the ruptured vessel using cardiopulmonary bypass, which is coded as 35211.

Operative report detailing the procedure, including the location and size of the ruptured vessel, the type of repair performed, and any complications encountered. Documentation of the use of cardiopulmonary bypass, including the type of cannulation used and the duration of bypass. Preoperative and postoperative imaging studies, such as CT scans or chest x-rays.
