ICD-10 Code I74.0 – Embolism and thrombosis of abdominal aorta (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I74.0 – Embolism and thrombosis of abdominal aorta
What it is
I74.0 identifies a blockage of the abdominal aorta caused by a clot or embolus. Use it when documentation states embolism or thrombosis in the abdominal segment of the aorta.
Clinical signs
Clinical features vary; refer to documentation. Patients may present with acute limb ischemia, abdominal pain, or diminished lower-extremity pulses when the aorta is obstructed.
When to use this code
Use this code when the provider documents embolism or thrombosis affecting the abdominal aorta, including imaging-confirmed occlusion. It also fits cases described as aortic thrombus or embolus in the abdominal aorta. If the record only says “aortic clot” without location, check documentation.
Do not use for
Do not use I74.0 for thoracic aortic disease, peripheral arterial embolism, or nonspecific vascular occlusion. If the site is elsewhere or the diagnosis is uncertain, verify the chart.
Coding tip
Code the abdominal aorta only when the anatomic site is clearly documented; otherwise, query for specificity.
