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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0314 includes procedures performed to bypass obstructed segments of the subclavian artery in the upper arteries. These ICD-10-PCS codes are used for inpatient documentation when a surgeon creates an alternate conduit to restore blood flow past a diseased portion of the left subclavian artery. Accurate coding within the ICD-10-PCS 0314 group is essential for proper inpatient reimbursement, as it captures the bypass procedure performed and determines appropriate case mix and payment.

Subclavian Artery, Left Bypass Procedure Overview

Procedures in this group involve creating an alternate route for blood flow by bypassing an occluded or narrowed segment of the left subclavian artery in the upper arterial system. These operations are classified under the Medical and Surgical section and use bypass techniques to restore perfusion to distal upper extremity tissues. Accurate ICD-10-PCS coding ensures inpatient procedures are captured correctly and supports appropriate case mix and reimbursement.

Typical Clinical Scenarios

A 68-year-old man presents emergently with acute left upper extremity ischemia after sudden onset of severe pain, pallor, and diminished pulses. Imaging reveals an occlusive thrombus at the proximal left subclavian artery proximal to the vertebral takeoff, and the vascular surgeon performs an open bypass from the left subclavian artery to the left lower arm artery using a synthetic graft to rapidly restore distal perfusion. This open bypass is chosen due to the arterial location and need for durable flow restoration. Typical codes: 03140J4
A 74-year-old woman with progressive claudication and nonhealing digital ulcers of the left hand secondary to chronic high-grade stenosis of the left subclavian artery is scheduled electively for revascularization. The surgeon performs an open bypass from the left subclavian artery to the left upper arm artery using autologous venous conduit harvested from the patient to provide long-term patency. The procedure is planned to relieve ischemic symptoms and promote wound healing. Typical codes: 0314091
A 62-year-old patient with prior subclavian-to-brachial bypass using a synthetic graft presents with graft infection and failing distal perfusion despite antibiotics. The operative plan is removal of the infected prosthetic material and creation of a new open bypass from the left subclavian artery to the left lower arm artery using autologous arterial tissue to reduce reinfection risk and reestablish blood flow. The case represents a revision for graft-related complication. Typical codes: 03140AB
