Acute embolism and thrombosis of left peroneal vein

This code signifies the sudden blockage of the left peroneal vein due to a blood clot (thrombus) or an embolus. This acute event restricts blood flow in the lower leg, potentially leading to pain, swelling, and other complications. It specifically identifies the left-sided involvement of this deep vein.

Use this code when documentation clearly indicates an acute embolism or thrombosis affecting the left peroneal vein. This typically occurs in the context of deep vein thrombosis (DVT) affecting the lower extremity. Supporting documentation should include imaging reports (e.g., ultrasound, venography) confirming the presence and location of the clot, along with clinical notes describing the acute onset of symptoms.

• Ensure the documentation specifies "acute" and "left" to accurately assign this code.
• Distinguish from chronic conditions or those affecting other veins (e.g., tibial, popliteal).
• Consider sequencing this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity being managed.
