Dissection of iliac artery

This code signifies an arterial dissection affecting the iliac artery, which is a tear in the inner lining of the artery, allowing blood to flow between the layers of the vessel wall. This can lead to a false lumen, potentially causing obstruction, aneurysm formation, or rupture.

Use this code when documentation explicitly states a dissection of the iliac artery. This includes spontaneous dissections, traumatic dissections, or iatrogenic dissections identified during diagnostic imaging (e.g., CT angiography, MRI, ultrasound) or surgical exploration.

• Ensure the documentation specifies "dissection" of the iliac artery, not just an aneurysm or stenosis.
• Do not confuse with other iliac artery conditions like atherosclerosis or thrombosis unless dissection is also present.
• Consider sequencing with codes for any associated complications, such as hemorrhage or ischemia, if documented.
