Acute embolism and thrombosis of popliteal vein, bilateral

This code signifies the sudden blockage of both popliteal veins, typically by a blood clot (thrombus) or other embolic material. This acute condition impairs blood flow from the lower legs, potentially leading to swelling, pain, and serious complications like pulmonary embolism.

Apply this code when documentation explicitly states an acute embolism or thrombosis affecting both popliteal veins. This diagnosis is often supported by imaging studies such as duplex ultrasound or venography confirming the presence of occlusive material in both popliteal veins.

• Ensure the documentation specifies "acute" to differentiate from chronic conditions.
• Verify that both popliteal veins are affected; separate codes exist for unilateral involvement.
• Always sequence this code after any underlying cause of the embolism or thrombosis, if known and documented.
