Ask Dr. Z

Our provider performed a balloon angioplasty on the superior mesenteric artery. CTA demonstrated a high-grade stenosis on a previously stent in the same SM artery. Our system is telling us that it requires a laterality modifier (which we have used in the past for upper extremity interventions). Being that in this case we have the balloon intervention in the superior mesenteric artery, we are seeking information on if possibly another CPT code is required or if a laterality modifier will be required.
