Phlebitis and thrombophlebitis of femoral vein, bilateral

This code signifies inflammation of the femoral veins, accompanied by the formation of blood clots, affecting both the left and right legs. This condition is a form of deep vein thrombosis (DVT) specifically located in the femoral veins. Patients typically present with pain, swelling, and tenderness in both thighs.

Use this code when documentation clearly indicates a diagnosis of phlebitis and thrombophlebitis involving the femoral vein in both lower extremities. This diagnosis is often supported by imaging studies such as duplex ultrasound confirming thrombus presence in the bilateral femoral veins.

• Ensure documentation explicitly states "bilateral" involvement of the femoral veins. If only one side is affected, a unilateral code should be used.
• Distinguish from superficial thrombophlebitis; this code is for deep vein involvement.
• Consider sequencing this code after any underlying cause, such as malignancy or hypercoagulable state, if applicable and documented.
