Embolism and thrombosis of thoracic aorta

AIClinical Context

Clinical Description

This code signifies the presence of a blood clot (embolus or thrombus) within the thoracic segment of the aorta. This condition can obstruct blood flow to vital organs supplied by the thoracic aorta, leading to ischemia or infarction.

When to Use

Assign this code when documentation explicitly states embolism or thrombosis affecting the thoracic aorta. This includes conditions like acute aortic occlusion due to a clot, or a thrombus identified within the thoracic aorta during imaging studies or surgical exploration.

Coding Tips

Differentiate from aortic dissection (I71.0x) or aneurysm with thrombosis (I71.x).
Specify laterality if applicable, though the thoracic aorta is a midline structure.
Look for documentation of the cause of the embolism/thrombosis, as additional codes may be warranted.
