Summary & Overview
CPT 73225: Magnetic Resonance Angiography of Upper Extremity
CPT code 73225 denotes magnetic resonance angiography (MRA) of the upper extremity, a diagnostic imaging procedure used to detect vascular abnormalities such as stenosis and aneurysm. This code is nationally relevant because MRA provides noninvasive visualization of arterial and venous structures and can influence management decisions for vascular disease, trauma, or preoperative planning. The procedure may be performed with contrast to improve vessel delineation.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical use of upper-extremity MRA, typical sites of service, and the payer landscape that affects coverage and billing practices. The publication summarizes benchmark utilization patterns and common billing considerations, highlights policy factors that can affect reimbursement decisions, and provides clinical context for when MRA of the upper extremity is indicated. Data not available in the input for specific ICD-10 pairings, associated taxonomies, and related codes are noted as unavailable in their respective sections. This summary serves as a concise reference for coders, billing managers, and policy analysts seeking a national-level understanding of CPT code 73225 and its role in vascular diagnostic imaging.
Billing Code Overview
CPT code 73225 describes a magnetic resonance angiography (MRA) of the upper extremity performed to evaluate the blood vessels for stenosis or aneurysm. The procedure is a diagnostic vascular imaging study that may include the administration of intravenous contrast to enhance vessel visualization.
Service Type: Diagnostic vascular imaging (MRA of upper extremity)
Typical Site of Service: Outpatient imaging center or hospital radiology department
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a history of peripheral vascular disease and progressive left upper extremity claudication is referred for diagnostic vascular imaging after abnormal duplex ultrasound and persistent ischemic symptoms. The referring vascular surgeon requests evaluation for suspected arterial stenosis or aneurysm of the subclavian and axillary arterial segments. The patient arrives at an outpatient imaging center and undergoes screening for MRI safety and renal function if contrast-enhanced imaging is planned. The MRI technologist reviews the clinical indication, positions the patient supine with the affected arm secured, and performs a contrast-enhanced magnetic resonance angiography of the upper extremity vasculature. The interpreting radiologist documents vessel anatomy, location and degree of stenosis, any aneurysmal dilation, and contrast-related observations. Imaging results are communicated to the referring provider, who uses the report to plan medical management, endovascular intervention, or surgical referral.
