Atheroembolism of left upper extremity

This code signifies the presence of an atheroembolism affecting the left upper extremity. This condition occurs when atherosclerotic plaque material dislodges from a proximal artery and travels to occlude smaller arteries in the arm, hand, or fingers, leading to ischemia.

Apply this code when documentation explicitly states an atheroembolism or "cholesterol emboli" syndrome impacting the left arm. This typically presents with symptoms such as pain, pallor, paresthesia, or pulselessness in the affected limb, often following an invasive vascular procedure or in patients with severe atherosclerosis.

• Ensure the documentation specifies "atheroembolism" or "cholesterol emboli" rather than a generic arterial embolism.
• Verify the laterality is clearly documented as "left upper extremity" to support this specific code.
• Consider sequencing this code after any underlying conditions, such as atherosclerosis, if applicable and documented as the primary cause.
