ICD-10 Code I75.89 – Atheroembolism of other site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I75.89 – Atheroembolism of other site
What it is
I75.89 identifies atheroembolism affecting a site other than the specifically listed locations in ICD-10-CM. It means cholesterol or plaque material has broken off and traveled to another vessel, causing blockage there.
Clinical signs
Clinical features vary; refer to documentation. You may see ischemic pain, reduced blood flow, or organ dysfunction in the affected area, depending on where the embolus lodged.
When to use this code
Use this code when the provider documents atheroembolism at an unspecified other site and the record does not name a more specific ICD-10-CM option. It is appropriate when the embolic source is atherosclerotic plaque and the site is clearly documented as “other.”
Code from the documented site and condition when a more specific diagnosis is available. Check documentation if the chart only says embolism, thrombosis, or vascular occlusion without confirming atheroembolism.
Do not use for
Do not use I75.89 for emboli from non-atherosclerotic causes or for atheroembolism in a specifically indexed site. If the record names another vascular disorder, code that condition instead.
Coding tip
Always confirm both the atheroembolism diagnosis and the exact site wording before assigning I75.89.
