Chronic embolism and thrombosis of left femoral vein

This code signifies a persistent or long-standing blockage of the left femoral vein due to an embolus (a traveling clot) or thrombosis (a clot formed in situ). This condition can lead to chronic venous insufficiency, pain, swelling, and skin changes in the affected lower extremity.

Assign this code when documentation clearly indicates a chronic, rather than acute, embolism or thrombosis affecting the left femoral vein. Supporting documentation should include physician notes detailing the chronicity of the condition, such as "chronic DVT of left femoral vein" or "history of left femoral vein thrombosis with ongoing symptoms."

• Differentiate carefully between acute (I82.412) and chronic conditions; documentation must specify chronicity.
• Ensure the laterality is correctly identified as "left" to avoid miscoding with the right (I82.511) or unspecified (I82.519) femoral vein.
• Consider co-reporting any associated complications, such as post-thrombotic syndrome (I87.0-) or venous insufficiency (I87.2-), if documented.
