Phlebitis and thrombophlebitis of popliteal vein, bilateral

This code signifies the presence of inflammation and clot formation within the popliteal veins in both legs. It indicates a deep vein thrombosis (DVT) affecting the major vein located behind the knee, occurring bilaterally. This condition can lead to pain, swelling, and warmth in the affected lower extremities.

This code is appropriate when documentation clearly states a diagnosis of phlebitis or thrombophlebitis specifically involving the popliteal veins in both the left and right legs. Supporting documentation would include physician notes detailing clinical findings consistent with DVT in both popliteal veins, along with imaging reports (e.g., duplex ultrasound) confirming the bilateral location of the thrombus.

• Ensure documentation explicitly states "bilateral" involvement of the popliteal veins; otherwise, a unilateral code would be more appropriate.
• Distinguish this from superficial thrombophlebitis; this code is for deep vein involvement.
• Consider sequencing this code after any underlying cause of the thrombophlebitis, if known and documented (e.g., malignancy, hypercoagulable state).
