Acute embolism and thrombosis of femoral vein, bilateral

This code signifies the sudden blockage of both femoral veins by an embolus (a traveling clot) or a thrombus (a clot formed in situ). This condition is a serious form of deep vein thrombosis (DVT) affecting the major veins in both upper legs, potentially leading to significant circulatory impairment and risk of pulmonary embolism.

Apply this code when documentation explicitly states acute embolism or thrombosis affecting both femoral veins. This diagnosis is typically supported by imaging studies such as duplex ultrasound or venography confirming the presence of acute thrombi in both femoral veins.

• Ensure documentation specifies "acute" and "bilateral" involvement of the femoral veins.
• Distinguish from chronic or unspecified thrombosis of the femoral vein, which would use different codes.
• Code any associated pulmonary embolism separately, as it represents a distinct and often life-threatening complication.
