Acute embolism and thombos unsp deep vn unsp lower extremity

This code signifies a sudden blockage of blood flow within an unspecified deep vein of an unspecified lower limb due to either an embolus (a traveling clot) or a thrombus (a stationary clot). It represents an acute vascular event affecting the venous system of the leg, without further specification of the exact vein or laterality.

This code is appropriate when documentation confirms an acute deep vein thrombosis (DVT) or embolism in a lower extremity, but the specific deep vein (e.g., femoral, popliteal) is not identified, and the laterality (left or right) is also not specified. It is a code of last resort when more specific information is unavailable in the medical record.

• Avoid using this code if the documentation specifies the affected deep vein (e.g., femoral, popliteal) or the laterality (left or right leg).
• Always query the provider for more specific anatomical location and laterality if possible, as more specific codes exist.
• This code should not be used for chronic deep vein thrombosis; separate codes exist for chronic conditions.
