Chronic embolism and thrombosis of left calf muscular vein

📋Clinical Description

This code signifies a persistent blockage within a muscular vein of the left calf, caused by either an embolus (a traveling clot) or a thrombus (a stationary clot). This condition indicates a long-standing vascular obstruction affecting the deep veins within the muscle compartments of the lower leg.

🎯When to Use

Apply this code when documentation specifies a chronic (long-term) venous occlusion in the left calf's muscular veins. This is typically supported by imaging studies (e.g., ultrasound, venography) confirming the presence and chronicity of the embolism or thrombosis in this specific anatomical location.

💡Coding Tips

Ensure documentation clearly specifies "chronic" and the exact location as "left calf muscular vein."
Distinguish from acute events; if acute, a different code from the I82.4- or I82.5- series would be appropriate.
Verify laterality; codes exist for the right calf and unspecified calf muscular veins.
