Chronic embolism and thrombosis of popliteal vein, bilateral

This code signifies the presence of a persistent blood clot (thrombosis) or a traveling clot (embolism) within both popliteal veins. This condition is chronic, indicating a long-standing or recurrent nature of the venous obstruction in the lower extremities. It specifically affects the veins located behind the knee.

Apply this code when documentation clearly indicates chronic venous obstruction, either embolic or thrombotic, affecting both popliteal veins. Supporting documentation would include imaging reports (e.g., duplex ultrasound, venography) confirming bilateral popliteal vein involvement and a physician's diagnosis specifying chronicity.

• Ensure documentation explicitly states "bilateral" involvement of the popliteal veins.
• Distinguish between acute (I82.43-) and chronic (I82.53-) conditions; this code is for chronic presentations only.
• Do not use this code for unspecified or unilateral popliteal vein thrombosis/embolism.
