Typical Clinical Scenarios

An elderly patient with progressive ischemia of the chest wall and compromised blood flow to a prior mastectomy flap presents electively for surgical reconstruction; imaging shows the right internal mammary artery is diseased and unsuitable for local repair, so the surgeon plans to replace the artery using autologous tissue graft during a scheduled inpatient procedure to restore perfusion to the flap. Typical codes: 03R007Z
A middle-aged patient arrives urgently after a right-sided thoracic trauma with laceration of the right internal mammary artery causing ongoing hemorrhage and ischemia to adjacent tissues; because the native vessel is irreparably damaged, the team performs an open replacement of the artery with a synthetic graft during the inpatient operative repair to control bleeding and reestablish arterial continuity. Typical codes: 03R00JZ
A patient with prior endovascular interventions on the right internal mammary artery develops graft failure and symptomatic restenosis, requiring a minimally invasive replacement of the artery via a percutaneous endoscopic approach using nonautologous tissue substitute to restore arterial flow; this inpatient procedure addresses the complication of prior graft loss and recurrent ischemic symptoms. Typical codes: 03R04KZ
