ICD-10 Code I75.01 – Atheroembolism of upper extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I75.01 – Atheroembolism of upper extremity
What it is
I75.01 identifies atheroembolism affecting the upper extremity. It means plaque material from a larger artery has traveled and blocked blood flow in an arm or hand vessel.
Clinical signs
Findings may include sudden pain, coldness, pallor, or reduced pulses in the affected upper limb. Clinical features vary; refer to documentation for the exact vessel and laterality.
When to use this code
Use this code when the record clearly documents embolic occlusion of an artery in the upper extremity caused by atherosclerotic debris. It is appropriate when the provider names atheroembolism, cholesterol embolus, or similar wording for the arm or hand. Check documentation if the source artery or site is unclear.
Do not use for
Do not use this code for emboli in other body regions or for general arterial occlusion without an atheroembolic cause. Do not assume laterality or location if the note does not specify the upper extremity.
Coding tip
Code only when the provider links the upper-extremity ischemic event to atheroembolism, not just to peripheral vascular disease.
