ICD-10-PCS Code For Subclavian Artery, Right: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 03H3 includes procedures performed to insert nonbiological appliances that monitor, assist, perform, or prevent a physiological function in the right subclavian artery. These ICD-10-PCS codes are used for inpatient documentation when a device is placed into the right subclavian artery to provide monitoring, circulatory support, or physiologic intervention. Accurate coding within the ICD-10-PCS 03H3 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Typical Clinical Scenarios

An elderly patient is admitted with unstable hemodynamics following major vascular surgery and requires continuous arterial pressure monitoring and potential intra-arterial infusion of vasoactive agents. A device is placed into the right subclavian artery to provide reliable invasive arterial access for monitoring and administration of medications; the procedure is performed percutaneously at the bedside due to urgent need. The insertion targets the right subclavian artery lumen to establish the monitoring/infusion conduit. Typical codes: 03H333Z, 03H33DZ
A patient scheduled for complex cardiothoracic surgery requires planned invasive arterial access for intraoperative hemodynamic monitoring and possible delivery of intra-arterial therapies. During the preoperative period in the operating room, an infusion catheter is inserted into the right subclavian artery under sterile conditions using an open surgical exposure to ensure secure placement for the anticipated procedure. The device provides continuous arterial monitoring and potential infusion capability throughout the operation. Typical codes: 03H303Z
A patient with a prior right subclavian arterial catheter develops catheter malfunction with lumen occlusion and recurrent ischemic symptoms distal to the access site; surgical exploration is undertaken to remove the dysfunctional intraluminal device and place a replacement appliance. The operating team performs an open insertion into the right subclavian artery to remove the failed device and establish a new functioning intraluminal appliance to restore monitoring and perfusion support. Typical codes: 03H30DZ
