ICD-10-PCS Code For Upper Extremity Arteries Right: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group B33H includes procedures performed to image arterial structures in the right upper extremity using magnetic resonance imaging. These ICD-10-PCS codes are used for inpatient documentation when magnetic resonance imaging of the right upper extremity arteries is performed for diagnostic evaluation or treatment planning. Accurate coding within the ICD-10-PCS B33H group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Upper Extremity Arteries Magnetic Resonance Imaging Procedure Overview

This code group covers magnetic resonance imaging of the right upper extremity arterial system, a diagnostic imaging procedure that captures multiplanar images of arterial structures using magnetic resonance technology. Procedures in this group target the upper arteries of the right arm and adjacent vascular segments to evaluate patency, stenosis, thrombosis, or vascular malformations. Accurate coding ensures inpatient records reflect the specific imaging performed and supports correct case mix assignment and reimbursement.

When to Use

Use a code from this group when an inpatient undergoes magnetic resonance imaging specifically targeting the right upper extremity arteries for evaluation of vascular pathology. Typical clinical indications include suspected arterial stenosis, thrombosis, embolic disease, or preprocedural vascular mapping.

Typical Clinical Scenarios

A 68-year-old patient is admitted from the emergency department with acute right arm ischemia characterized by sudden onset pain, pallor, and diminished distal pulses after atrial fibrillation onset. Inpatient magnetic resonance imaging of the right upper extremity arterial system is performed to evaluate for arterial occlusion or embolus and to delineate the location and extent of arterial compromise prior to urgent vascular intervention. The study is obtained with and without contrast as clinically indicated to maximize detection of intraluminal thrombus and flow abnormalities. Typical codes: B33HY0Z
A 55-year-old patient with known peripheral arterial disease and chronic right forearm claudication is admitted for preprocedural vascular mapping before planned endovascular revascularization. Inpatient magnetic resonance imaging of the right upper extremity arteries is ordered to provide high-resolution multiplanar images of the brachial, radial, and ulnar arteries to plan the approach and device selection. The exam may be performed with contrast to better define vessel lumen and stenotic segments. Typical codes: B33HY0Z, B33HZZZ
A 72-year-old patient presents with swelling and prolonged pain of the right upper extremity after recent catheter-based vascular procedure, raising concern for postprocedural arterial dissection or thrombotic complication. Inpatient magnetic resonance imaging of the right upper extremity arterial system is obtained to assess vessel integrity, detect dissection flaps, and evaluate for thrombus without exposing the patient to additional ionizing radiation. The exam may be performed without contrast if renal function is impaired, or with contrast if needed to clarify uncertain findings. Typical codes: B33HYZZ, B33HZZZ
