ICD-10-PCS Code For Innominate Artery: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0372 includes procedures performed to dilate the lumen of the innominate artery in the upper arteries. These ICD-10-PCS codes are used for inpatient documentation when a clinician performs dilation to relieve stenosis or obstruction of the innominate artery to improve arterial blood flow. Accurate coding within the ICD-10-PCS 0372 group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and supports clinical documentation accuracy.

Innominate Artery Dilation Procedure Overview

Procedures in this group involve dilation of the innominate artery within the upper arterial circulation to expand the lumen and restore or improve blood flow. These interventions target the upper arteries and may be performed endovascularly or via open access depending on clinical indications. Accurate coding to the correct International Classification of Diseases, Tenth Revision, Procedure Coding System code is important for inpatient documentation and reimbursement because it ensures the procedure performed is precisely captured and supports appropriate case mix assignment.

When to Use

Use a code from this group when an inpatient receives a documented dilation procedure of the innominate artery to address narrowing or blockage. Codes in this group apply when the operative report or catheterization documentation specifies dilation of the innominate artery as the primary procedure.

Typical Clinical Scenarios

An elderly patient presents to the emergency department with acute right arm weakness and dizziness; imaging reveals high-grade stenosis of the innominate artery causing cerebral hypoperfusion and embolic risk. Because the lesion is focal and urgent restoration of arterial lumen is required, an endovascular percutaneous dilation with placement of a single drug-eluting stent is performed during the same inpatient admission to re-establish flow and reduce restenosis risk. Typical codes: 037234Z
A middle-aged patient with progressive exertional right arm claudication and vertebrobasilar insufficiency on outpatient workup is admitted electively for planned revascularization of a tight innominate artery stenosis. The vascular team performs a percutaneous endovascular dilation using a drug-coated balloon without placement of an intraluminal device to minimize long-term antiplatelet needs while achieving lumen expansion. Typical codes: 03723Z1
A patient who previously underwent innominate artery stenting presents with recurrent symptoms and imaging demonstrates in-stent restenosis of a previously placed metal stent. During the inpatient procedure, the team performs percutaneous endovascular dilation and deploys two intraluminal devices to scaffold the lesion and address recurrent narrowing. Typical codes: 037235Z
