Other arterial embolism and thrombosis of abdominal aorta

This code signifies the presence of a blood clot (embolism or thrombosis) within the abdominal aorta, excluding cases specifically involving the aortic bifurcation. This condition obstructs blood flow to organs and tissues supplied by the abdominal aorta and its branches, potentially leading to ischemia and organ damage.

Use this code for documented cases of arterial embolism or thrombosis located anywhere along the abdominal aorta, except for the specific involvement of the aortic bifurcation. Documentation should clearly state the presence of an embolism or thrombosis in the abdominal aorta and specify that it is not at the bifurcation.

• Distinguish carefully between embolism/thrombosis of the abdominal aorta and the aortic bifurcation (I74.01).
• Ensure documentation specifies the location within the abdominal aorta if known, to rule out bifurcation involvement.
• Code any associated complications, such as organ infarction or ischemia, as secondary diagnoses.
