ICD-10 Code I74.09 – Other arterial embolism and thrombosis of abdominal aorta (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I74.09 – Other arterial embolism and thrombosis of abdominal aorta
What it is
I74.09 identifies an embolus or thrombus obstructing the abdominal aorta, outside the more specific aortic occlusion categories. Use it when documentation states an arterial blockage in the abdominal aorta.
Clinical signs
Findings may include sudden abdominal, back, or lower-extremity ischemic pain, diminished pulses, or signs of acute limb ischemia. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents embolism or thrombosis involving the abdominal aorta and does not specify a more exact aortic site or type. It may apply in acute or chronic settings if the record clearly identifies the abdominal aorta as the affected vessel. Check documentation for laterality or more specific vascular descriptors.
Do not use for
Do not use this code for embolism or thrombosis in peripheral arteries, iliac vessels, or thoracic aorta. If the record names a different arterial location, code that site instead.
Coding tip
Confirm the vessel is the abdominal aorta and not a nearby branch before assigning I74.09.
