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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 05L6 includes procedures performed to occlude vessels in the left subclavian vein. These ICD-10-PCS codes are used for inpatient documentation when a procedure completely closes the lumen of the left subclavian vein to stop blood flow. Accurate coding within the ICD-10-PCS 05L6 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Typical Clinical Scenarios

An unstable adult trauma patient presents with penetrating chest injury and ongoing hemorrhage suspected to involve the left subclavian vein; after imaging and failed conservative measures, the surgical team performs an open repair that includes deliberately occluding the left subclavian vein to control bleeding and prevent exsanguination. Typical codes: 05L60ZZ, 05L60DZ
An oncology patient with a symptomatic arteriovenous fistula and recurrent high-output cardiac failure from a chronic left subclavian vein–chest wall communication electively undergoes a percutaneous endovascular procedure to completely close the left subclavian vein lumen using an intraluminal occlusion device to reduce shunting and relieve symptoms. Typical codes: 05L64DZ, 05L63DZ
A patient with a malfunctioning tunneled left subclavian dialysis catheter develops severe infection and thrombosis despite antibiotics; during a subsequent percutaneous thrombectomy and debridement the vein is permanently occluded with an extraluminal device to prevent recurrent catheter-related sepsis and persistent thrombus propagation. Typical codes: 05L63CZ, 05L64CZ
