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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0373 includes procedures performed to dilate vascular structures in the right subclavian artery. These ICD-10-PCS codes are used for inpatient documentation when an interventional procedure is performed to widen the lumen of the right subclavian artery to improve blood flow or relieve stenosis. Accurate coding within the ICD-10-PCS 0373 group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and determines appropriate case mix and payment.

Subclavian Artery Dilation Procedure Overview

This procedure group includes dilation of the right subclavian artery and targets the upper arteries within the cardiovascular system. Procedures in this group involve widening the lumen of the right subclavian artery to restore or improve blood flow. Accurate ICD-10-PCS coding is important for inpatient reimbursement because it documents the specific arterial intervention performed and supports appropriate case mix and payment.

Typical Clinical Scenarios

An elderly patient with symptomatic right arm ischemia presents urgently with acute worsening of exertional arm pain and coolness of the right upper extremity. Imaging shows severe focal atherosclerotic stenosis of the right subclavian artery proximal to the vertebral takeoff, and endovascular dilation with stent placement is planned during the inpatient admission to restore flow. A percutaneous approach with one drug-eluting intraluminal device is commonly used to achieve durable vessel patency in this setting. Typical codes: 037334Z
A middle-aged patient with chronic right subclavian artery stenosis causing exertional arm fatigue and vertebrobasilar insufficiency undergoes a scheduled inpatient interventional procedure after noninvasive workup. The procedure is elective and performed percutaneously to dilate the lesion using a drug-coated balloon without implanting an intraluminal device to reduce restenosis risk. This planned approach targets symptom relief and improvement in cerebral and upper extremity perfusion. Typical codes: 03733D1
A patient previously treated with percutaneous angioplasty of the right subclavian artery returns with recurrent restenosis and recurrent arm claudication. During the inpatient admission the surgeon performs repeat dilation and deploys two intraluminal devices to scaffold the vessel and address recurrent narrowing. A percutaneous approach with two intraluminal devices is appropriate for this revision of prior endovascular therapy. Typical codes: 037335Z, 03733EZ
