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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 05L4 includes procedures performed to occlude venous lumens in the left innominate vein. These ICD-10-PCS codes are used for inpatient documentation when complete closure of the left innominate vein lumen is performed for therapeutic, hemostatic, or other clinical indications. Accurate coding within the ICD-10-PCS 05L4 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Innominate Vein, Left Occlusion Procedure Overview

Procedures in this group involve completely closing the lumen of the left innominate vein within the upper venous system. These occlusion procedures target the left innominate vein to stop blood flow through the vessel for therapeutic or hemostatic purposes. Accurate ICD-10-PCS coding of these procedures ensures inpatient records reflect the specific body part and operation performed and supports correct case mix classification and payment.

Typical Clinical Scenarios

An elderly patient on anticoagulation presents to the emergency department with sudden, large-volume venous hemorrhage from a traumatic injury to the left lower neck/chest region with uncontrolled bleeding from the left innominate vein. After resuscitation, the vascular surgery team performs an open exposure and places an extraluminal vascular clamp and prosthetic patch to completely occlude the injured left innominate vein to control hemorrhage. The acute life-saving intervention requires complete closure of the venous lumen by open approach. Typical codes: 05L40CZ
A middle-aged patient with chronic central venous stenosis and symptomatic venous hypertension of the left upper extremity undergoes a planned percutaneous endovascular procedure to intentionally occlude flow in the left innominate vein prior to creation of a left-sided dialysis access. An intraluminal vascular occlusion device is deployed percutaneously under fluoroscopic guidance to permanently close the lumen and redirect venous return. Typical codes: 05L43DZ
A patient with a history of multiple prior central line infections and a failed percutaneous coil attempt returns with persistent fistula and recurrent sepsis originating from the left innominate vein. During a subsequent percutaneous endoscopic procedure, no device is available that can be safely left in place, so the team performs complete occlusion of the left innominate vein lumen using direct percutaneous endoscopic techniques without placement of a separate device to definitively exclude the infected segment. Typical codes: 05L44ZZ
