Acute embolism and thombos unsp deep veins of low extrm, bi

This code signifies the sudden blockage of an unspecified deep vein in both lower extremities due to an embolus (a traveling clot) or a thrombus (a stationary clot). This condition is acute, meaning it has a sudden onset and is of recent duration. It represents a serious vascular event requiring prompt medical attention.

Use this code when documentation clearly indicates an acute deep vein thrombosis (DVT) or embolism affecting both lower extremities, but the specific deep vein involved (e.g., femoral, popliteal) is not specified. This code is appropriate when the physician's notes confirm the bilateral nature and acute onset of the venous occlusion.

• Ensure documentation explicitly states "acute" and "bilateral" involvement of the lower extremities.
• Avoid using this code if a more specific deep vein (e.g., femoral, popliteal) is identified; instead, select the appropriate code for that specific vein.
• Always review the medical record for laterality and acuity to prevent miscoding.
