Acute embolism and thrombosis of unspecified popliteal vein

This code signifies a sudden blockage of blood flow in an unspecified popliteal vein due to a blood clot. This acute event can lead to pain, swelling, and warmth in the affected lower leg, and if untreated, can have serious complications.

Apply this code when documentation clearly indicates an acute venous thromboembolism (VTE) affecting the popliteal vein, and the laterality (left or right) is not specified. This diagnosis is typically supported by imaging studies such as ultrasound or venography confirming the presence of a thrombus.

• Ensure the documentation specifies "acute" to differentiate from chronic conditions.
• Avoid using this code if the laterality (left or right popliteal vein) is documented; instead, select the more specific code.
• Consider sequencing this code after any underlying conditions contributing to the thrombosis, such as malignancy or hypercoagulable states.
