Acute embolism and thombos unsp deep veins of l low extrem

This code signifies a sudden blockage of blood flow in an unspecified deep vein within the left lower limb due to a blood clot. This condition is acute, meaning it has a recent onset, and the specific deep vein affected is not documented. It represents a serious vascular event requiring prompt medical attention.

Apply this code when documentation confirms an acute deep vein thrombosis (DVT) or embolism affecting the left lower extremity, but the specific deep vein (e.g., femoral, popliteal, tibial) is not specified. This code is appropriate when the physician's notes indicate "acute DVT of left leg, unspecified deep vein" or similar phrasing.

• Ensure the documentation explicitly states "acute" and "unspecified deep veins" of the left lower extremity.
• Avoid using this code if a more specific deep vein is identified; instead, use the appropriate anatomical site code.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting treatment.
