Acute embolism and thrombosis of deep vein of l low extrem

This code signifies the sudden blockage of a deep vein in the left lower extremity, excluding the femoral, iliac, or popliteal veins, due to a blood clot. This acute event can lead to pain, swelling, and warmth in the affected limb, potentially causing significant circulatory compromise.

Apply this code when documentation clearly indicates an acute deep vein thrombosis (DVT) or embolism affecting a specific, non-femoral, non-iliac, and non-popliteal deep vein in the left leg. Supporting documentation includes imaging reports (e.g., duplex ultrasound, venography) confirming the location and acute nature of the clot, along with physician notes detailing the patient's symptoms and diagnosis.

• Ensure the documentation specifies "acute" to differentiate from chronic conditions.
• Verify the exact location of the deep vein in the left lower extremity; avoid using this code if the femoral, iliac, or popliteal veins are specified.
• Always sequence this code after any underlying cause, such as a hypercoagulable state or malignancy, if applicable.
