ICD-10 Code I75.019 – Atheroembolism of unspecified upper extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I75.019 – Atheroembolism of unspecified upper extremity
What it is
I75.019 identifies cholesterol or atherosclerotic debris that has broken loose and traveled to an upper extremity artery, causing blockage. Use this code when the affected arm or hand is not further specified.
Clinical signs
Typical findings include sudden ischemic pain, coolness, pallor, numbness, or diminished pulses in the affected upper limb. Clinical features vary; refer to documentation.
When to use this code
Use I75.019 when the provider documents atheroembolism affecting an upper extremity but does not identify the side or a more specific artery. It also fits notes describing embolic ischemia from atherosclerotic plaque in the arm or hand. Check documentation if the record instead names a different embolic source.
Do not use for
Do not use this code for emboli from cardiac, thrombotic, or other non-atherosclerotic sources. Do not assign it when the documentation specifies a more exact upper-extremity site or a different vascular disorder.
Coding tip
Look for the exact source and limb laterality in the note before selecting this unspecified code.
