Ac emblsm and thombos unsp deep veins of left prox low extrm

This code signifies a sudden blockage of an unspecified deep vein in the upper part of the left leg (e.g., femoral, popliteal) due to a blood clot. This condition is acute, meaning it has a recent onset, and can lead to significant pain, swelling, and potential complications like pulmonary embolism.

Use this code for patients presenting with symptoms of an acute deep vein thrombosis (DVT) in the left proximal lower extremity where the specific deep vein involved is not documented. Documentation should clearly indicate "acute," "embolism" or "thrombosis," and "left proximal lower extremity deep vein" without further specificity.

• Ensure documentation specifies "acute" onset; otherwise, consider chronic DVT codes.
• Avoid this code if a more specific deep vein (e.g., femoral, popliteal) is identified; use the corresponding specific code.
• Always review for any associated pulmonary embolism, which would require an additional code.
