ICD-10 Code I75.011 – Atheroembolism of right upper extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I75.011 – Atheroembolism of right upper extremity
What it is
I75.011 identifies a cholesterol or atheromatous embolus that has traveled to arteries of the right upper extremity. It indicates arterial blockage caused by plaque material, not a primary clot in the limb.
Clinical signs
Findings may include sudden arm pain, coolness, pallor, numbness, or reduced pulses in the right upper limb. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents atheroembolism affecting the right arm or upper extremity. It fits cases where the source is an atherosclerotic plaque and the laterality is clearly right-sided. If the note only says embolism or limb ischemia, check documentation for the specific cause and side.
Do not use for
Do not use it for emboli of uncertain origin, thromboembolism, or left-sided or bilateral upper-extremity disease. Check documentation.
Coding tip
Confirm both the embolic cause and the right upper-extremity laterality before assigning I75.011.
