Typical Clinical Scenarios

A critically ill intensive care patient with continuous arterial pressure monitoring needs invasive access after peripheral radial sites are unavailable due to trauma or surgery; the left ulnar artery is chosen for placement of an arterial catheter at bedside using a percutaneous technique to monitor hemodynamics and obtain blood gases. Typical codes: 03HA3DZ, 03HA33Z
An elective vascular access procedure on a hospitalized patient requiring long-term intra-arterial infusion therapy for chemotherapy or regional vasopressor delivery; the left ulnar artery is surgically accessed in the operating room and a conduit/infusion device is inserted via an open approach to provide controlled arterial infusion. Typical codes: 03HA03Z, 03HA0DZ
A patient with a previously placed percutaneous arterial monitoring line develops malfunction and thrombotic occlusion necessitating inpatient revision; the team removes the failed device and places a new intraluminal monitoring device into the left ulnar artery using a percutaneous endoscopic or percutaneous approach to restore monitoring. Typical codes: 03HA4DZ, 03HA3DZ
