ICD-10 Code I74.01 – Saddle embolus of abdominal aorta (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I74.01 – Saddle embolus of abdominal aorta
What it is
I74.01 identifies an embolus that lodges at the aortic bifurcation and blocks blood flow into the lower body. It is used when the embolus is specifically described as a saddle embolus of the abdominal aorta.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include sudden lower-extremity ischemia, pain, pallor, coolness, pulselessness, or neurologic changes from reduced perfusion.
When to use this code
Use this code when the provider documents a saddle embolus in the abdominal aorta, including imaging or operative findings that localize the embolus to the aortic bifurcation. You should also use it when the note clearly distinguishes embolic occlusion from thrombosis or aneurysm. Check documentation if the site or mechanism is unclear.
Do not use for
Do not use I74.01 for aortic thrombosis, aneurysm with mural thrombus, or emboli in other arterial sites. If the record only says “aortic occlusion” without saddle embolus, check documentation.
Coding tip
Code the documented embolus location precisely; “saddle” and “abdominal aorta” must be supported in the chart.
