Acute emblsm and thombos unsp deep vn unsp distal low extrm

This code signifies the sudden blockage of an unspecified deep vein in an unspecified distal lower extremity due to a blood clot. It indicates an acute event affecting the lower leg or foot, where the specific deep vein involved (e.g., posterior tibial, peroneal) is not documented.

Use this code when documentation confirms an acute deep vein thrombosis (DVT) or embolism in the distal lower extremity, but the specific deep vein affected is not identified. This often occurs when imaging reports (e.g., ultrasound) confirm a DVT in the calf or foot region without specifying the exact vessel.

• Avoid using this code if the specific deep vein (e.g., popliteal, femoral) is documented; instead, use a more specific code from the I82.4- series.
• Ensure the documentation clearly states "acute" to support the "acute" nature of the embolism/thrombosis.
• This code should be used when laterality (left or right) is also unspecified in the documentation.
