Injury of left iliac vein, initial encounter

This code signifies a traumatic injury specifically to the left iliac vein, which is a major blood vessel draining blood from the left leg and pelvis into the inferior vena cava. Such injuries can range from contusions to complete lacerations, potentially leading to significant hemorrhage or thrombosis.

Assign this code when documenting the initial treatment for a patient presenting with an injury to their left iliac vein, typically resulting from blunt force trauma, penetrating wounds, or iatrogenic causes during surgical procedures. This code is appropriate for the first encounter related to this specific injury.

• Always confirm the laterality (left) and the specific vessel (iliac vein) from the physician's documentation.
• Ensure the "A" seventh character is used only for the initial encounter for active treatment of the injury.
• Look for associated injuries to surrounding structures, such as arteries, nerves, or organs, and code them separately.
