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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group X27C includes procedures performed to dilate intraluminal structures in the left basilic vein. These ICD-10-PCS codes are used for inpatient documentation when dilation of the left basilic vein is performed using an intraluminal device via a percutaneous approach under the New Technology section. Accurate coding within the ICD-10-PCS X27C group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and determines appropriate case mix and payment.

Left Basilic Vein Dilation Procedure Overview

Procedures in this group involve dilation of the left basilic vein using intraluminal devices and are coded in the New Technology section of the International Classification of Diseases, 10th Revision, Procedure Coding System. These procedures target the cardiovascular system and expand the lumen of the basilic vein to improve blood flow or allow device placement. Accurate coding ensures inpatient records reflect the specific dilation procedure performed and supports appropriate case mix and payment determination.

When to Use

Use a code from this group when a percutaneous dilation of the left basilic vein is performed with a cell impermeable intraluminal device during an inpatient encounter. These codes apply when the primary operative action is dilation of the left basilic vein rather than other vascular interventions.

Typical Clinical Scenarios

An adult patient admitted from the emergency department with acute symptomatic upper extremity swelling and pain after recently placed dialysis catheter attempts failed on the right side. Duplex ultrasound demonstrates a high-grade stenosis of the left basilic vein compromising venous outflow and access maturation. Percutaneous dilation of the left basilic vein with a cell-impermeable intraluminal device is performed during the same admission to restore lumen patency and facilitate subsequent vascular access or relieve symptoms. Typical codes: X27C35B
A patient with end-stage renal disease is admitted electively for creation of an upper arm arteriovenous fistula; preoperative imaging shows focal stenosis of the left basilic vein that would impede fistula maturation. During the planned inpatient procedure, the left basilic vein is dilated percutaneously using a cell-impermeable intraluminal device to optimize vessel caliber before or in conjunction with fistula creation. Typical codes: X27C35B
A patient presents inpatient for revision of a previously failed left upper-arm vascular access with recurrent venous stenosis identified on venography. To salvage the access and avoid more extensive surgery, clinicians perform percutaneous dilation of the left basilic vein with a cell-impermeable intraluminal device to re-establish adequate lumen diameter and improve flow through the access circuit. Typical codes: X27C35B
