Major laceration of unspecified kidney, initial encounter

This code signifies a significant, deep tear or cut to an unspecified kidney, indicating a severe injury that likely extends through the renal capsule and into the parenchyma. Such a laceration suggests substantial damage to the kidney's structure, potentially leading to significant bleeding and functional impairment.

Apply this code when documentation confirms a major laceration of the kidney, but the specific kidney (left or right) is not specified in the medical record. This is appropriate for the initial treatment of such an injury, typically seen in trauma cases like motor vehicle accidents, falls, or direct blows to the flank.

• Ensure the documentation clearly states "major laceration" or similar terminology indicating a severe tear, not just a contusion or minor laceration.
• Only use this code when the laterality of the injured kidney is explicitly unknown or unrecorded. If left or right is specified, a more precise code should be used.
• The "A" at the end signifies an initial encounter for active treatment of the injury. Subsequent care would use different seventh characters.
