Embolism and thrombosis of other parts of aorta

This code signifies the presence of an embolism or thrombosis affecting any part of the aorta other than the abdominal aorta, thoracic aorta, or aortic bifurcation. This includes conditions like an aortic arch thrombus or a thrombus in a specific aortic segment not otherwise specified. It represents an acute or chronic occlusion of the aortic lumen due to a blood clot.

Use this code when documentation specifies an embolism or thrombosis within an unspecified or "other" part of the aorta. This is appropriate for conditions such as a mural thrombus in the ascending aorta or a saddle embolus not specifically at the bifurcation. Supporting documentation should clearly identify the aorta as the affected vessel and specify the nature of the occlusion (embolism or thrombosis).

• Ensure the documentation explicitly states "other parts of aorta" or a specific aortic segment not covered by more specific codes (I74.0-I74.11).
• Distinguish from codes for embolism/thrombosis of specific aortic segments (e.g., I74.0 for abdominal aorta, I74.10 for thoracic aorta, I74.11 for aortic bifurcation).
• Always sequence this code after any underlying cause, if applicable, such as atrial fibrillation (I48.-) or atherosclerosis (I70.-).
