Chronic embolism and thrombosis of right popliteal vein

This code signifies the persistent presence of a blood clot within the right popliteal vein, leading to an obstruction of blood flow. This condition is chronic, indicating it has been ongoing or recurrent, and can result in symptoms such as swelling, pain, and skin changes in the lower leg.

Apply this code when documentation clearly states a chronic embolism or thrombosis specifically affecting the right popliteal vein. This diagnosis is typically supported by imaging studies (e.g., duplex ultrasound, venography) confirming the presence and chronicity of the clot.

• Ensure documentation specifies "chronic" to differentiate from acute popliteal vein thrombosis.
• Verify laterality (right) is explicitly stated; do not assume.
• Code any associated post-thrombotic syndrome separately if documented.
