Typical Clinical Scenarios

An elderly patient with sudden ischemic rest pain and cool, pale fingers after an acute thrombotic occlusion of the right ulnar artery admitted from the emergency department for limb-threatening distal ischemia. After initial anticoagulation and imaging confirm a focal high-grade stenosis amenable to endovascular therapy, inpatient percutaneous dilation is performed to restore flow and perfusion to the hand. Typical codes: 03793ZZ, 037934Z
A middle-aged patient with progressive claudication of the right hand and documented chronic right ulnar artery stenosis seen on outpatient vascular testing who is admitted electively for definitive revascularization after failed conservative care. A planned percutaneous endovascular procedure using a drug-coated balloon is performed to enlarge the arterial lumen and reduce restenosis risk. Typical codes: 03793Z1, 03793D1
A patient with prior right ulnar artery stent placement who develops recurrent symptomatic restenosis and requires inpatient repeat intervention; imaging shows in-stent restenosis requiring dilation and possible placement of an additional intraluminal device. The procedure is performed percutaneously to re-dilate the artery and deploy one or more drug-eluting intraluminal devices as needed. Typical codes: 037935Z, 03793EZ
