Minor contusion of left kidney, initial encounter

This code signifies a superficial bruise or mild injury to the left kidney, without significant tissue damage or rupture. It indicates that the kidney has sustained a minor impact, resulting in localized bleeding and swelling but maintaining its structural integrity.

This code is appropriate for patients presenting with blunt trauma to the left flank or back, where imaging (e.g., CT scan) reveals a low-grade contusion of the left kidney. It is used when the injury is the primary reason for the patient's current encounter and treatment.

• Ensure documentation specifies "minor" or "grade I" contusion of the left kidney.
• Verify that the encounter is the initial treatment for this specific injury.
• Do not use for more severe kidney injuries (e.g., lacerations, ruptures) or for contusions of the right kidney.
