CPT 37255: Angioplasty of Additional Iliac Vessel

Medicare pays $528 on average nationally for this procedure.

CPT code 37255 describes angioplasty (balloon dilation) of a straightforward stenotic lesion in an additional iliac artery (common, internal, or external) performed at the same session as an initial iliac revascularization; the service includes all access, catheterization, lesion crossing, and imaging guidance needed to complete the procedure and may be performed via open or percutaneous approach, categorized as an adjunct endovascular/vascular intervention typically provided in an operating room, vascular suite, or interventional radiology suite during the same hospitalization or same-day surgical encounter.

Clinical & Coding Specifications

Clinical Context

A 68-year-old male with progressive right lower-extremity claudication and an ankle-brachial index of 0.6 is diagnosed with symptomatic peripheral arterial disease involving the iliac segment. Pre-procedure CTA shows a primary lesion in the right common iliac artery successfully treated with an initial iliac revascularization (stent or angioplasty). During the same endovascular session the interventionalist identifies a separate, straightforward focal stenosis in the ipsilateral external iliac artery and performs balloon angioplasty of that additional vessel.

The clinical workflow includes: pre-procedure evaluation (history, vascular exam, noninvasive arterial testing, imaging review), informed consent, percutaneous arterial access (commonly common femoral), diagnostic angiography, treatment of the index iliac lesion (angioplasty ± stent), identification of the second straightforward lesion within the same iliac vascular territory, performance of balloon angioplasty of that additional lesion (including catheterization, lesion crossing, inflation/deflation with appropriate balloon sizing), intraprocedural imaging guidance (fluoroscopy/angiography), hemostasis and access site management, and post-procedure monitoring with discharge planning and antiplatelet therapy as indicated.
