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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0377 includes procedures performed to dilate vessels in the brachial artery, right. These ICD-10-PCS codes are used for inpatient documentation when a clinician performs a lumen-expanding intervention on the right brachial artery to restore or improve blood flow. Accurate coding within the ICD-10-PCS 0377 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Brachial Artery, Right Dilation Procedure Overview

This procedure group includes dilation of the right brachial artery, a branch of the upper arterial system supplying the arm. These procedures expand the lumen of the brachial artery to improve blood flow or relieve stenosis. Accurate ICD-10-PCS coding captures the specific arterial site and operation, which affects inpatient reimbursement and clinical case mix assignment.

Typical Clinical Scenarios

A patient presents to the emergency department with acute limb ischemia of the right forearm after sudden thrombosis of a previously patent radial-brachial arterial segment; signs include severe pain, pallor, and diminished pulses. Urgent inpatient endovascular intervention is performed to rapidly restore lumen patency and reperfusion of the arm through dilation of the right brachial artery via a percutaneous approach. Typical codes: 03773ZZ, 037734Z
An older patient with chronic right arm claudication from symptomatic atherosclerotic stenosis of the right brachial artery is admitted electively for planned revascularization when conservative therapy fails; the goal is durable lumen expansion often with stent placement. A percutaneous endoscopic or percutaneous dilation with placement of an intraluminal device is performed to relieve the stenosis and improve functional blood flow. Typical codes: 03774DZ, 03773Z1
A patient returns to the hospital with recurrent right brachial artery restenosis months after prior angioplasty; the inpatient procedure addresses symptomatic recurrent narrowing and may use drug-eluting intraluminal devices or drug-coated balloon technology to reduce re-restenosis risk. The intervention is focused on re-dilation of the right brachial artery and may involve placement of one or more drug-eluting devices or use of a drug-coated balloon via a percutaneous approach. Typical codes: 037735Z, 03773D1
