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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group X278 includes procedures performed to dilate lumens or orifices in the cardiovascular system in the left axillary vein. These ICD-10-PCS codes are used for inpatient documentation when dilation of the left axillary vein is performed percutaneously, often with placement of an intraluminal device to restore venous patency. Accurate coding within the ICD-10-PCS X278 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Left Axillary Vein Dilation Procedure Overview

This procedure group covers dilation of the left axillary vein and targets the cardiovascular system. These percutaneous procedures involve widening the lumen of the left axillary vein, often using intraluminal devices to restore or improve venous flow. Accurate coding of these procedures is important for inpatient reimbursement because it documents the specific vascular intervention performed and supports appropriate case mix assignment.

When to Use

Use a code from this group when a percutaneous dilation of the left axillary vein is performed during an inpatient encounter. This applies when the clinical intent is to widen the vein lumen, for example to relieve stenosis or reestablish patency, using appropriate devices.

Typical Clinical Scenarios

A hemodialysis patient with a tunneled left upper-extremity arteriovenous fistula presents with acute onset of arm swelling and diminished dialysis flow; venography identifies a critical stenosis of the left axillary vein causing outflow obstruction, and inpatient percutaneous balloon dilation with placement of a cell-impermeable intraluminal device is performed to restore patency and allow effective dialysis access. Typical codes: X27835B
An elderly hospitalized patient with progressive left arm venous claudication and recurrent cellulitis after prior catheter-related thrombosis undergoes an elective percutaneous left axillary vein dilation with placement of a cell-impermeable intraluminal device to relieve chronic stenosis and improve venous drainage; the procedure is done during the inpatient stay for medical optimization and monitoring. Typical codes: X27835B
A patient develops symptomatic restenosis at a previously treated left axillary vein site with recurrent edema and impaired venous return shortly after initial intervention; during the same admission a percutaneous revisional dilation using a cell-impermeable intraluminal device (new technology device) is performed to re-expand the lumen and address the complication. Typical codes: X27835B
