ICD-10-PCS Code For Brachial Artery, Left: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0378 includes procedures performed to dilate vascular structures in the left brachial artery. These ICD-10-PCS codes are used for inpatient documentation when a clinician performs lumen-expanding interventions on the left brachial artery to improve or restore arterial blood flow. Accurate coding within the ICD-10-PCS 0378 group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and supports clinical documentation accuracy.

Brachial Artery, Left Dilation Procedure Overview

This procedure group covers dilation of the left brachial artery within the upper arterial system. Procedures involve expanding the lumen of the left brachial artery using mechanical or catheter-based techniques to restore or improve blood flow. Accurate ICD-10-PCS coding of these procedures ensures correct inpatient documentation and supports appropriate reimbursement.

Typical Clinical Scenarios

An older patient with known peripheral arterial disease presents to the hospital with progressively worsening claudication and an angiogram showing a focal high-grade stenosis of the left brachial artery limiting distal perfusion. After diagnostic imaging, the vascular team performs a planned percutaneous transluminal dilation of the lesion with placement of a single drug-eluting stent to reduce restenosis risk. The procedure is performed percutaneously to restore arterial lumen and improve upper extremity blood flow. Typical codes: 037834Z
A middle-aged patient arrives to the emergency department with acute onset left hand pallor, pain, and diminished pulses after thrombosis of a previously stenotic segment in the left brachial artery following trauma. In the inpatient setting an urgent percutaneous endovascular dilation is performed using a drug-coated balloon to rapidly re-establish flow while minimizing vessel injury and reducing the risk of recurrent narrowing. The intervention targets the left brachial artery lumen to restore perfusion to the distal extremity. Typical codes: 03783Z1
A patient with prior left brachial artery stenting develops recurrent symptomatic restenosis months after the index procedure, with recurrent ischemic symptoms and angiographic evidence of in-stent narrowing. During the inpatient admission the surgeon performs an open approach dilation with placement of two intraluminal devices to scaffold the vessel and address the recurrent lumen loss. The operation focuses on dilating the left brachial artery and placing multiple intraluminal devices to treat the recurrence. Typical codes: 037805Z
