CPT® Code 35903

The procedure described by CPT® Code 35903 involves the excision of an infected vascular graft located in an extremity. A vascular graft is a medical device used to replace or repair damaged blood vessels, and when such a graft becomes infected, it poses significant risks to the patient's health. The excision of the infected graft is a critical surgical intervention aimed at removing the source of infection to prevent further complications. Prior to the excision, a re-vascularization procedure is typically performed, which involves the placement of a new graft. This step is essential to ensure that the affected limb or organ continues to receive adequate blood flow during and after the removal of the infected graft. The surgical process includes careful exposure and dissection of the infected graft from surrounding tissues, clamping of the inflow and outflow arteries to control blood flow, and meticulous debridement of the arterial walls at the anastomosis sites to remove any inflamed tissue. The procedure concludes with the repair of the arterial defect using sutures, ensuring the integrity of the blood vessels is restored. This code is specifically designated for extremity grafts, distinguishing it from similar procedures performed on grafts located in other anatomical regions, such as the neck, thorax, or abdomen.
