Acute embolism and thombos of calf muscular vein, bilateral

This code signifies the sudden blockage of a muscular vein in both calves due to an embolus (a traveling clot) or a thrombus (a clot formed in place). This condition is acute, meaning it has a sudden onset and is of recent duration. It specifically refers to the deep veins within the calf muscles, not the main superficial or deep veins of the leg.

Use this code when documentation clearly indicates an acute, bilateral occlusion of the calf muscular veins. This diagnosis is typically supported by imaging studies such as duplex ultrasound showing thrombus in the gastrocnemius or soleus veins of both lower extremities. The patient would likely present with acute pain, swelling, and tenderness in both calves.

• Ensure documentation specifies "acute" and "bilateral" involvement of the calf muscular veins.
• Distinguish from deep vein thrombosis (DVT) of the main leg veins (e.g., popliteal, femoral), which are coded differently.
• Always review imaging reports and physician notes for precise anatomical location and laterality.
