Ac emblsm and thombos unsp deep veins of dist low extrm, bi

This code signifies the sudden blockage of blood flow in the deep veins located in the lower part of both legs, below the knee, due to a blood clot. This condition is acute, meaning it has a rapid onset, and the specific deep vein affected is not documented.

Apply this code when documentation clearly indicates an acute deep vein thrombosis (DVT) or embolism affecting the distal lower extremities (e.g., calf veins) of both legs, and the specific vein involved is not specified. This is typically supported by imaging studies (e.g., duplex ultrasound) confirming bilateral distal DVT.

• Ensure documentation specifies "acute" and "bilateral" involvement of the distal lower extremities.
• Avoid using this code if a more specific deep vein (e.g., posterior tibial, peroneal) is identified; instead, use the appropriate specific code.
• Distinguish from chronic DVT, which would require a different code from the I82.5- series.
