ICD-10 Code I74.19 – Embolism and thrombosis of other parts of aorta (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I74.19 – Embolism and thrombosis of other parts of aorta
What it is
I74.19 identifies an embolus or thrombus blocking another part of the aorta, excluding the abdominal and thoracic aorta codes. Use it when documentation specifies aortic obstruction in a different aortic segment.
Clinical signs
Clinical features vary; refer to documentation. Findings may include acute ischemic pain, diminished distal pulses, or signs of reduced blood flow related to the affected aortic branch or segment.
When to use this code
Use this code when the provider documents embolism or thrombosis in an aortic location not captured by a more specific aortic site code. It may also apply when imaging or operative notes identify the involved aortic segment clearly.
If the record only says “aortic thrombus” without location, check documentation before coding. Confirm whether the event is embolic, thrombotic, or due to another vascular disorder.
Do not use for
Do not use it for embolism or thrombosis of the abdominal or thoracic aorta when a more specific code applies. Do not use for nonspecific arterial occlusion without documented aortic involvement.
Coding tip
Verify the exact aortic segment in the report; the site drives code selection.
