Acute embolism and thrombosis of left femoral vein

This code signifies the sudden blockage of the left femoral vein by an embolus (traveling clot) or a thrombus (stationary clot forming in the vessel). This condition is an acute venous thromboembolism (VTE) affecting a major deep vein in the left leg.

Use this code when documentation clearly indicates an acute deep vein thrombosis (DVT) or embolism specifically located in the left femoral vein. Supporting documentation would include imaging reports (e.g., ultrasound, venography) confirming the presence and location of the clot, along with physician notes describing the acute onset of symptoms.

• Differentiate between acute and chronic presentations; this code is strictly for acute events.
• Ensure the laterality (left) is explicitly documented and matches the code.
• Do not confuse with superficial thrombophlebitis or thrombosis of other deep veins.
