Summary & Overview
CPT 37253: Intravascular Ultrasound for Additional Noncoronary Vessel
CPT code 37253 is an add-on code for intravascular ultrasound (IVUS) performed in each additional noncoronary vessel during diagnostic or interventional vascular procedures. IVUS provides high-resolution, intraluminal imaging via a catheter-mounted ultrasound transducer to assess vessel morphology, guide stent placement, and confirm treatment success. As an add-on code, 37253 is reported in conjunction with the primary procedure for the first vessel and captures additional vessel imaging when clinically indicated. Nationally, IVUS supports precision in endovascular care and can affect procedure planning, device selection, and documentation requirements.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find the clinical context for when intravascular ultrasound is used in noncoronary vessels, how 37253 functions as an add-on reporting mechanism, and what operational areas typically apply (hospital catheterization labs, endovascular suites, and interventional radiology). The publication summarizes benchmark considerations, payer coverage themes, and relevant documentation elements needed to support reporting of add-on noncoronary IVUS. Data not available in the input are noted where applicable.
Billing Code Overview
CPT code 37253 describes an add-on intravascular ultrasound (IVUS) procedure for each additional noncoronary vessel evaluated during a diagnostic or interventional therapeutic vascular procedure. The procedure uses a catheter with an ultrasound transducer that is inserted into the vessel (intravascular) to image the vessel interior and guide or assess interventions such as stent placement for obstructions or blockages.
-
Service type: Intravascular ultrasound imaging as an add-on service during diagnostic or interventional vascular procedures (noncoronary)
-

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with peripheral arterial disease presents with progressive claudication and an angiographically significant stenosis of the superficial femoral artery during a planned endovascular intervention. The interventionalist performs diagnostic angiography followed by lesion crossing and balloon angioplasty with possible stent placement. During this noncoronary endovascular procedure the provider inserts an intravascular ultrasound catheter to visualize vessel lumen size, plaque morphology, and stent apposition to guide appropriate device sizing and optimal treatment. The procedure typically occurs in an inpatient or outpatient hospital-based cardiac catheterization lab or vascular interventional suite; radiology supervision and interpretation are performed by the attending interventionalist or vascular specialist. Clinical workflow: pre-procedure consent and evaluation, vascular access (commonly femoral), baseline angiography, intravascular ultrasound (IVUS) catheter insertion and imaging of the target vessel(s), therapeutic intervention (angioplasty/stent) as indicated, repeat IVUS to confirm results, hemostasis, and post-procedure monitoring and documentation including radiological interpretation.
