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 X276 includes procedures performed to dilate lumens in the left subclavian vein. These ICD-10-PCS codes are used for inpatient documentation when a dilation of the left subclavian vein is performed using an intraluminal device via a percutaneous approach. Accurate coding within the ICD-10-PCS X276 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Left Subclavian Vein Dilation Procedure Overview

This procedure group includes dilation of the left subclavian vein using intraluminal devices and is coded in the New Technology section of the International Classification of Diseases, Tenth Revision, Procedure Coding System. These procedures target the cardiovascular system and involve expanding the lumen of the left subclavian vein to improve blood flow. Accurate coding is important for inpatient reimbursement because it documents the specific vascular intervention performed and supports appropriate case mix and payment.

Typical Clinical Scenarios

An elderly dialysis-dependent patient with a tunneled catheter develops progressive ipsilateral arm swelling and ultrasound-confirmed high-grade stenosis of the left subclavian vein causing inadequate dialysis flows; the patient is admitted from clinic for inpatient endovascular intervention to restore luminal patency and enable effective hemodialysis. A percutaneous dilation using a cell impermeable intraluminal device is performed to reestablish flow and preserve vascular access. Typical codes: X27635B
A middle-aged patient with a history of left-sided pacemaker lead placement presents with worsening venous congestion and arm pain; imaging shows symptomatic focal stenosis of the left subclavian vein refractory to conservative measures, so a scheduled inpatient percutaneous venoplasty with an intraluminal device is undertaken to relieve the obstruction and prevent lead-related complications. Typical codes: X27635B
A trauma patient in the inpatient setting develops thrombosis-related scarring and symptomatic narrowing of the left subclavian vein after central line placement, causing compromised venous return and limb ischemic symptoms; after anticoagulation and evaluation, the vascular surgery team performs percutaneous dilation with a cell impermeable intraluminal device to expand the lumen and address the sequelae of the injury. Typical codes: X27635B
