Phlebitis and thrombophlebitis of unspecified femoral vein

This code signifies inflammation of an unspecified femoral vein, accompanied by the formation of a blood clot within that vein. It indicates a deep vein thrombosis (DVT) affecting the femoral vein when the laterality (right or left) is not documented.

Use this code when the medical record clearly documents phlebitis and thrombophlebitis of the femoral vein, but the specific side (left or right) is not specified by the provider. This diagnosis is typically supported by imaging studies such as ultrasound confirming the presence of a thrombus and inflammation.

• Avoid using this code if the laterality of the femoral vein is documented; instead, choose a more specific code (I80.11- or I80.12-).
• Ensure the documentation explicitly states "femoral vein" and not a more distal or proximal vein.
• Consider sequencing this code after any underlying conditions contributing to the thrombophlebitis, such as malignancy or hypercoagulable states.
