Typical Clinical Scenarios

A critically ill adult in the intensive care unit with septic shock requires reliable central venous access for vasopressor administration and central venous pressure monitoring; the team elects a left subclavian approach when internal jugular access is contraindicated or anatomy prevents safe placement, and a nonbiological infusion device is inserted percutaneously for short- to intermediate-term use. Typical codes: 05H633Z, 05H63DZ
An oncology patient admitted electively for planned long-term chemotherapy port placement via the left subclavian vein because peripheral access is poor; the procedure is performed in the inpatient setting using an open or percutaneous technique to place a tunneled infusion device for repeated infusions and blood draws. Typical codes: 05H603Z, 05H633Z
A hospitalized patient with a malfunctioning left subclavian tunneled catheter (thrombosis or catheter fracture) requires removal and immediate replacement of the device during the same admission to restore central venous access; the procedure may involve insertion of a new intraluminal or infusion device via a percutaneous or open approach depending on clinical findings. Typical codes: 05H63DZ, 05H60DZ
