Chronic embolism and thrombosis of calf muscular vein, bilateral

📋Clinical Description

This code signifies the presence of a persistent blood clot (thrombosis) or a traveling clot (embolism) within the muscular veins of both calves. This condition is long-standing, indicating it is not an acute or recent event.

🎯When to Use

Apply this code when documentation clearly indicates chronic venous thromboembolism affecting the muscular veins of both lower legs, specifically the calf region. Supporting documentation should specify the chronicity and bilateral involvement, often found in imaging reports (e.g., ultrasound, venography) or physician notes detailing long-term management.

💡Coding Tips

Ensure documentation explicitly states "chronic" and "bilateral" involvement of the calf muscular veins.
Distinguish from acute events (I82.50-I82.55) or unspecified chronicity.
Do not confuse with deep vein thrombosis (DVT) of the popliteal, tibial, or peroneal veins, which have distinct codes.
