Typical Clinical Scenarios

An elderly patient with a history of peripheral arterial disease and a previously placed intraluminal drug-eluting stent in a femoral artery presents acutely with limb ischemia and imaging shows stent fracture and loss of patency; the patient is admitted for inpatient revision to restore arterial flow and correct the malfunctioning intraluminal device. Typical codes: 04WY0DZ, 04WY3DZ
A middle-aged patient with chronic venous insufficiency had an extraluminal arterial monitoring catheter placed during a prior hospitalization and now has persistent pain and suspected catheter migration causing arterial wall irritation; a planned inpatient procedure is performed to reposition or revise the extraluminal device in the lower arterial system to resolve symptoms and prevent further injury. Typical codes: 04WY0CZ, 04WY3CZ
A younger trauma patient with an implanted arterial infusion pump in a lower artery develops device infection and partial device failure requiring open surgical revision to remove infected components and revise the infusion system to the extent possible before reimplantation or alternative management. Typical codes: 04WY03Z, 04WY0JZ
