ICD-10 Code I75.022 – Atheroembolism of left lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I75.022 – Atheroembolism of left lower extremity
What it is
This code identifies cholesterol or atheromatous material that has broken away and blocked blood flow in the left lower extremity. It reflects an embolic arterial problem, not simple peripheral artery disease.
Clinical signs
Findings may include sudden pain, coldness, pallor, diminished pulses, or ischemic changes in the left leg or foot. Clinical features vary; refer to documentation.
When to use this code
Use I75.022 when the record specifically documents atheroembolism affecting the left lower extremity. You may also use it when the provider describes cholesterol emboli or embolic occlusion in that limb. Confirm laterality and that the event is arterial, not venous.
Do not use for
Do not use this code for nonspecific leg ischemia, routine peripheral vascular disease, or emboli without documented atheroembolism. Check documentation if the site or cause is unclear.
Coding tip
Verify left-sided laterality and explicit atheroembolism wording before assigning I75.022.
