Phlebitis and thrombophlebitis of left popliteal vein

This code signifies inflammation of the left popliteal vein accompanied by the formation of a blood clot (thrombus). This condition typically presents with localized pain, swelling, tenderness, and warmth in the popliteal fossa (behind the knee). It is a form of superficial thrombophlebitis affecting a specific deep vein.

Use this code when documentation clearly indicates a diagnosis of phlebitis and thrombophlebitis specifically affecting the left popliteal vein. This diagnosis is often supported by physical examination findings, ultrasound imaging confirming a thrombus in the left popliteal vein, and patient symptoms localized to the left popliteal area.

• Ensure laterality is explicitly documented as "left" for the popliteal vein.
• Distinguish from deep vein thrombosis (DVT) of other lower extremity veins; this code is specific to the popliteal.
• Do not use if the condition is superficial phlebitis without thrombus, or if the thrombus is in a different vein.
