Acute embolism and thrombosis of left tibial vein

This code signifies the sudden blockage of the left tibial vein by an embolus (a traveling clot) or a thrombus (a stationary clot formed within the vessel). This acute event obstructs blood flow, potentially leading to pain, swelling, and other signs of venous insufficiency in the lower leg.

Apply this code when documentation clearly indicates an acute onset of a thrombotic or embolic event specifically affecting the left tibial vein. Supporting documentation should include diagnostic imaging (e.g., ultrasound, venography) confirming the presence and location of the clot, along with clinical signs and symptoms consistent with acute venous occlusion.

• Differentiate between acute and chronic conditions; this code is for acute presentations only.
• Ensure the laterality (left) and specific vessel (tibial vein) are explicitly documented.
• Do not confuse with superficial thrombophlebitis; this code is for deep vein thrombosis (DVT) of the tibial vein.
