ICD-10 Code I75.012 – Atheroembolism of left upper extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I75.012 – Atheroembolism of left upper extremity
What it is
I75.012 identifies atheroembolism affecting the left upper extremity. It means debris from atherosclerotic plaque has traveled and blocked blood flow in an artery of the left arm.
Clinical signs
Documented findings may include sudden pain, pallor, coolness, numbness, or reduced pulses in the left arm. Clinical features vary; refer to documentation.
When to use this code
Use I75.012 when the provider documents atheroembolism in the left upper extremity or clearly identifies embolic plaque material causing arterial obstruction there. You should code from the documented site and laterality, not from suspected vascular disease alone.
If the record only mentions limb ischemia without naming atheroembolism, check documentation. Confirm that the left upper extremity is the affected location before assigning this code.
Do not use for
Do not use this code for embolism from other causes, generalized atherosclerosis, or disease in a different limb. Check documentation if the site or cause is unclear.
Coding tip
Match the code to both the documented cause and the left-sided upper-extremity site.
