Laceration of left renal vein, initial encounter

This code signifies a tear or cut in the main vein draining the left kidney. Such an injury can lead to significant blood loss and compromise kidney function. It typically results from blunt or penetrating trauma to the flank or abdomen.

Apply this code for the initial treatment of a patient presenting with a confirmed laceration of the left renal vein. This includes emergency department visits, initial surgical repair, or the first encounter for diagnostic workup following the injury.

• Ensure documentation specifies the left renal vein; otherwise, an unspecified laterality code may be more appropriate.
• Confirm the encounter is indeed the "initial encounter" for this specific injury. Subsequent care would require a different seventh character.
• Always code any associated external cause of injury (e.g., fall, motor vehicle accident) to provide a complete clinical picture.
