Acute embolism and thombos of deep vein of low extrm, bi

This code signifies the sudden blockage of blood flow in deep veins of both lower extremities due to a blood clot (embolism) or the formation of a blood clot within the vein itself (thrombosis). This condition is acute, meaning it has a sudden onset and is typically severe, requiring immediate medical attention.

Use this code when documentation clearly indicates an acute deep vein thrombosis (DVT) or embolism affecting deep veins in both lower limbs, and the specific deep vein is not further specified as popliteal, tibial, peroneal, or calf. Supporting documentation would include physician notes detailing bilateral lower extremity DVT, imaging reports (e.g., duplex ultrasound) confirming bilateral deep vein involvement, and an acute presentation.

• Ensure the documentation explicitly states "bilateral" involvement of the lower extremities.
• Verify that the condition is acute; chronic DVT of other specified deep veins would be coded differently.
• Do not use this code if a more specific deep vein (e.g., popliteal, tibial) is identified for the bilateral DVT; refer to the more granular codes within the I82.4- series.
