Chronic embolism and thrombosis of left popliteal vein

This code signifies a persistent blockage of the left popliteal vein due to an embolus (a traveling clot) or thrombosis (a clot formed in place). This chronic condition indicates a long-standing obstruction affecting blood flow in the specified lower extremity vein.

Apply this code when documentation clearly states a chronic embolism or thrombosis specifically located in the left popliteal vein. This is typically supported by imaging studies (e.g., ultrasound, venography) confirming the chronic nature and location of the occlusion.

• Ensure documentation specifies "chronic" and the exact location as "left popliteal vein."
• Distinguish from acute conditions (I82.432) and other venous sites.
• Consider sequencing with any underlying conditions contributing to the embolism/thrombosis (e.g., hypercoagulable states).
